         ITEM 5.   OTHER EVENTS.

         On March 2, 1999, the Registrant completed a private offering of 10,000
units (the  "Units"),  each  consisting of $10,000  principal  amount of 11 1/2%
senior  notes due 2006 (the  "Notes")  and  warrants to  purchase  150 shares of
common stock of the Registrant,  par value $.01 ("Common  Stock") at an exercise
price of $6.25 per share (the "Warrants").

         First Albany Corporation (the "Initial Purchaser")  initially purchased
the Units at a discount of 2.5% of the principal  amount of the Notes. The price
to  purchasers  of Units from the Initial  Purchaser  was 100% of the  principal
amount of the Notes.

         The net proceeds to the  Registrant  from the sale of the Units,  after
deducting the discount to the Initial  Purchaser and related issuance costs, was
approximately  $97.3  million.  The  Registrant  will  use the net  proceeds  to
complete a buyback of 500,000 shares of Common Stock, finance pending and future
acquisitions, repay outstanding debt, as well as for general corporate purposes.

         Delivery of the Units was made on March 2, 1999 through the  facilities
of the  Depository  Trust  Company,  against  payment  therefor  in  immediately
available funds.

         The Notes,  in the aggregate  principal  amount of  $100,000,000,  were
issued under an Indenture  dated March 2, 1999  between the  Registrant  and IBJ
Whitehall Bank & Trust Company, as trustee, and mature on January 15, 2006.

         The Notes bear  interest  at a rate of 11 1/2% per annum  except as set
forth  below.  In the event that the  Registrant  has not  achieved  an Adjusted
Stockholders'  Equity (as  defined  herein)  of at least $40  million by each of
December 31, 1999, June 30, 2000 and December 31, 2000, the interest rate of the
Notes shall be adjusted on the date following such dates to 13%, 14% and 15% per
annum, respectively,  except as such rate may be adjusted as otherwise set forth
herein in  connection  with a default of the  Registrant's  obligation  to file,
cause to be declared effective and keep effective registration  statements filed
with the Securities and Exchange  Commission.  "Adjusted  Stockholders'  Equity"
means the Registrant's stockholders' equity as shown on its consolidated balance
sheets  filed as part of its regular  reports with the  Securities  and Exchange
Commission,  less the amount of any increase therein resulting from the issuance
of  shares  of  Common  Stock  in  exchange  for   outstanding   7%  convertible
subordinated notes due 2005 of the Registrant,  to the extent, if any, that such
issuance exceeds 2,343,646 shares of Common Stock in the aggregate.

         Interest  accrues  on the  Notes  from the  March  2,  1999 and will be
payable semi-annually in arrears on each January 15 and July 15, commencing July
15,  1999,  to  holders  of  record  of the  Notes  on  January  1 and  July  1,
respectively,  subject  to  prepayment  under  certain  circumstances  described
herein.



<PAGE>



         Pursuant  to  a  registration  rights  agreement,   the  Registrant  is
obligated to file a registration statement under the Securities Act of 1933 with
respect to either (i) an exchange offer with respect to the Notes 
(the "Exchange Offer")  or (ii) resales of the Notes, and, if the Registrant 
does not either make such a filing prior to the date that is 180 days  after  
March 2,  1999,  or does not  consummate  such Exchange  Offer or cause a shelf 
registration  statement  with  respect to such resales to be declared  effective
on or prior to the date that is 240 days after March 2, 1999,  the interest  
rate on the Notes will increase by 0.5% per annum, in either case for so long as
 such failure continues.


         Upon a Change of Control (as defined in the Indenture),  the Registrant
will be required,  subject to certain conditions, to make an offer to repurchase
all of the  outstanding  Notes  at a  purchase  price  equal  to 101%  of  their
principal  amount,  plus  accrued  and  unpaid  interest  to the  date  of  such
repurchase.

         The  Warrants,  representing  the right to  purchase  an  aggregate  of
1,500,000  shares of Common Stock,  were issued pursuant to a Warrant  Agreement
dated  March 2, 1999  between  the  Registrant  and IBJ  Whitehall  Bank & Trust
Company, as warrant agent.

         The Warrants are  exercisable  from and after September 2, 1999, to and
including  March 2, 2004.  Each Warrant  entitles the holder thereof to purchase
one share of Common Stock at an exercise price of $6.25 per share. The number of
shares for which,  and the price per share at which,  a Warrant is  exercisable,
are subject to adjustment  upon the  occurrence of certain events as provided in
the Warrant Agreement.

         Pursuant to a registration rights agreement, the Registrant is required
within  180 days of March 2, 1999 to file a shelf  registration  statement  with
respect to the resale of the  Warrants,  the  issuance of Common  Stock upon the
exercise of the Warrants and,  under certain  circumstances  if required by law,
the resale of Common Stock  issuable upon  exercise of the Warrants,  and to use
its reasonable best efforts to cause such registration  statement to be declared
effective,  subject to certain exceptions,  on or before 240 days after March 2,
1999.  If the  Registrant  does not  comply  with  its  obligations  under  this
registration  rights agreement the interest rate on the Notes will be subject to
increase by 0.5% for so long as such failure continues.  The Registrant has also
agreed to do all things  reasonably  required to maintain  the  quotation of the
Common Stock on the Nasdaq SmallCap Market.

First Albany Corporation
30 South Pearl Street
Albany, NY 12201

Ladies and Gentlemen:

         Waste  Systems   International,   Inc.,  a  Delaware  corporation  (the
"Company"),  and the  subsidiaries  of the Company set forth in Exhibit D hereto
(the  "Subsidiary   Guarantors")  confirm  their  agreement  with  First  Albany
Corporation (the "Initial  Purchaser") with respect to the issue and sale by the
Company and the  purchase by the Initial  Purchaser  of  $100,000,000  aggregate
principal  amount of the  Company's 11 1/2% Senior Notes due 2005 (the  "Notes")
and 1,500,000  Warrants of the Company (the "Warrants"),  each Warrant entitling
the holder  thereof to purchase  one share of common  stock,  par value $.01 per
share, of the Company (the "Common Stock").  The Notes and Warrants will be sold
in Units (the  "Units"),  each Unit  consisting of $10,000  principal  amount of
Notes and 150  Warrants.  The Notes are to be issued  pursuant to the  Indenture
dated as of March 2, 1999 (the "Indenture"), between the Company, the Subsidiary
Guarantors and IBJ Whitehall Bank & Trust Company,  as trustee (the  "Trustee").
The  Company's  obligations  under the  Notes,  including  the due and  punctual
payment of  interest on the Notes,  will be  unconditionally  guaranteed  by the
Subsidiary  Guarantors.  The Warrants  are to be issued  pursuant to the Warrant
Agreement  dated as of March 2,  1999 (the  "Warrant  Agreement"),  between  the
Company and IBJ Whitehall Bank & Trust  Company,  as warrant agent (the "Warrant

referred to herein as "Warrant Shares."

         The Company  understands that the Initial Purchaser proposes to make an
offering of the Units on the terms and in the manner set forth herein and in the
Offering  Memorandum (as hereinafter  defined) as soon as the Initial  Purchaser
deems advisable after this Agreement has been executed and delivered, subject to
the  conditions set forth herein and in the Units,  Notes and Warrants,  to, and
only to,  qualified  institutional  buyers  (each,  a  "Qualified  Institutional
Buyer") as defined in Rule 144A ("Rule 144A") under the  Securities Act of 1933,
as amended (the  "Securities  Act"),  in transactions  exempt from  registration
under the  Securities Act pursuant to Rule 144A. The Notes and Warrants shall be
separately transferable immediately upon issuance.  Holders of the Notes will be
entitled to the benefits of the Note Registration  Rights Agreement of even date
herewith (the "Note  Registration  Rights Agreement")  between the Company,  the
Subsidiary  Guarantors and the Initial Purchaser,  pursuant to which the Company
will file a  registration  statement  (the  "Registration  Statement")  with the
Securities and Exchange  Commission (the "Commission")  under the Securities Act
registering the Notes or the Exchange Notes referred to in the Note Registration
Rights  Agreement.  Holders of the Warrants  will be entitled to the benefits of
the Warrant  Registration  Rights  Agreement of even date herewith (the "Warrant
Registration Rights Agreement") between the Company,  the Subsidiary  Guarantors
and the  Initial  Purchaser,  pursuant  to which the  Company  will file a shelf
registration   statement  (the  "Warrant   Registration   Statement")  with  the
Commission  under the  Securities Act  registering  the Warrants and the Warrant
Shares referred to in the Warrant Registration Rights Agreement. As used herein,
this Agreement,  the Indenture,  the Warrant  Agreement,  the Note  Registration
Rights  Agreement  and  the  Warrant  Registration  Rights  Agreement  shall  be
collectively  referred to as the "Transaction  Documents." The Units, the Notes,
the  Warrants  and the  Transaction  Documents  are more fully  described in the

the registration requirements thereunder. The Company has prepared and delivered

1999 (such preliminary offering memorandum, including the documents incorporated

thereof in  connection  with the  offering  and resale of the Units as  provided
herein.  The Company is also preparing and will deliver to the Initial Purchaser

memorandum, including the documents incorporated or deemed to be incorporated by
reference therein,  in the form first furnished to the Initial Purchaser for use
in connection  with the offering of the Units being  hereinafter  referred to as
the "Final Offering  Memorandum") and hereby authorizes the Initial Purchaser to
distribute  copies  thereof in  connection  with the  offering and resale of the
Units  as  provided  herein.  All  references  herein  to  information  that  is
"included" or "contained" in the  Preliminary  Offering  Memorandum or the Final
Offering  Memorandum,  and all  references  of like  import,  shall  include the
information (including financial statements)  incorporated by reference therein,

Claims"), pending or, to the best of the Company's knowledge, threatened against
the Company or any of its  subsidiaries  or any person or entity whose liability
for any Environmental  Claim the Company or any of its subsidiaries has retained
or assumed either  contractually or by operation of law; and (iv) to the best of
the  Company's  knowledge,  there are no past or  present  actions,  activities,
circumstances,  conditions, events or incidents,  including, without limitation,
the  release,  emission,  discharge,  presence or  disposal  of any  Material of
Environmental  Concern,  that reasonably could result in a material violation of
any  Environmental  Law or form the  basis of a  potential  Environmental  Claim
against  the  Company  or any  of its  subsidiaries,  including  any  Subsidiary
Guarantor, or against any person or entity whose liability for any Environmental
Claim the Company or any of its  subsidiaries  has  retained  or assumed  either
contractually or by operation of law. (xxiii) Cost of Environmental  Compliance.
In the ordinary course of its business, the Company conducts periodic reviews of
the effect of Environmental  Laws on the business,  operations and properties of
the  Company  and its  subsidiaries,  in the course of which it  identifies  and
evaluates associated costs and liabilities (including,  without limitation,  any
capital or operating  expenditures required for clean-up,  closure of properties
or compliance with  Environmental Laws or any permit,  license or approval,  any
related  constraints on operating  activities  and any potential  liabilities to
third  parties).  On the basis of such reviews and the amount of its established
reserves,  the Company has reasonably  concluded that such associated  costs and
liabilities  would not,  individually or in the aggregate,  result in a Material
Adverse Effect.  (xxiv) No Registration  Required.  Subject to compliance by the
Initial Purchaser with the representations,  warranties and agreements set forth
in Section 3 hereof, the Company is not required by applicable law or regulation
in  connection  with the offer,  sale and  delivery  of the Units to the Initial
Purchaser,  or in connection with the initial resale of the Units by the Initial
Purchaser in the manner  contemplated by this  Agreement,  to register the Units
under the Securities Act or to qualify the Indenture  under the Trust  Indenture
Act of 1939, as amended (the "Trust  Indenture  Act").  (xxv) No Sale of Shares.
Except as described in the Offering  Memorandum and except for 455,922 shares of
Common Stock issued in connection  with the acquisition on September 21, 1998 of
Mattei-Flynn  Trucking,  Incorporated,  neither  the  Company  nor  any  of  its
subsidiaries,  including any Subsidiary Guarantor, has sold or issued any shares
of Common Stock of the Company during the six-month period preceding the date of
the Offering Memorandum, including any sales pursuant to Rule 144A, Regulation D
or Regulation S under the Securities  Act, other than shares issued  pursuant to
stock plans of the Company or issued upon conversion of convertible  securities.
(xxvi)  Investment  Company Act. The Company is not, and after giving  effect to
the offering and sale of the Units will not be, an "investment  company"  within
the meaning of such term under the Investment  Company Act of 1940 and the rules
and  regulations of the Commission  thereunder (the  "Investment  Company Act").
(xxvii)  Rule 144A  Eligibility.  No  securities  of the same class  (within the
meaning of Rule 144A(d)(3)  under the Securities Act) as the Units, the Notes or
the Warrants are listed on any national  securities  exchange  registered  under
Section 6 of the Exchange Act or quoted on an  automated  interdealer  quotation
system.  The Company has been  advised  that the Notes have been  designated  as
securities  eligible  for the Private  Offerings,  Resales  and Trading  through
Automated  Linkages  ("PORTAL") in accordance  with the rules and regulations of
the National  Association  of Securities  Dealers,  Inc.  ("NASD").  (xxviii) No
Stabilization.  Neither the Company nor any of its  subsidiaries,  including any
Subsidiary Guarantor, has taken or will take, directly or indirectly, any action
designed  to,  or that  might be  reasonably  expected  to,  cause or  result in
stabilization or manipulation of the price of the Units, the Notes, the Warrants
and the Warrant Shares. (xxix) No General Solicitation. None of the Company, its
Affiliates under the Securities Act, or any person acting on its or any of their
behalf has directly,  or through any agent (provided that no  representation  is
made as to the Initial Purchaser or any person acting on its behalf),  (i) sold,
offered for sale, solicited offers to buy or otherwise negotiated in respect of,
any security (as defined in the Securities  Act) which is or would be integrated
with the  offering  and sale of the Units in a manner  that  would  require  the
registration  of the Units under the  Securities Act or (ii) engaged in any form
of general  solicitation  or general  advertising  (within  the  meaning of Rule
502(c) of the Securities  Act) in connection  with the offering of the Units. As
used in this Agreement,  the term "Affiliate"  shall have the meaning given such
term by Rule 501(b) of Regulation D under the Securities Act. (xxx) Tax Returns.
The  Company  and each of its  subsidiaries,  including  each of the  Subsidiary
Guarantors,  have filed all federal,  state,  local and foreign tax returns that
are required to be filed or have duly requested extensions thereof and have paid
all taxes required to be paid by each of them and any related assessments, fines
or penalties, except for any such tax, assessment, fine or penalty that is being
contested  in good  faith  and by  appropriate  proceedings.  Adequate  charges,
accruals  and  reserves  have  been  provided  for in the  financial  statements
referred to in Section 1(a)(iii) above in respect of all federal,  state,  local
and foreign  taxes for all periods as to which the tax  liability of the Company
or any of its  subsidiaries  has not been finally  determined or remains open to
examination by applicable taxing  authorities.  (xxxi) Absence of Labor Dispute.
No labor dispute with the  employees of the Company or any of its  subsidiaries,
including any Subsidiary  Guarantor,  exists or, to the Company's knowledge,  is
imminent,  and the  Company  is not  aware of any  existing  or  imminent  labor
disturbance  by the  employees  of any  of  its  or any  subsidiary's  principal
suppliers,  customers or  contractors,  which, in either case, may reasonably be
expected to result in a Material Adverse Effect.  (xxxii) Internal Controls. The
Company  maintains  a  system  of  accounting  controls  sufficient  to  provide
reasonable  assurances  that (i)  transactions  are executed in accordance  with
management's general or specific  authorization;  (ii) transactions are recorded
as necessary to permit  preparation of financial  statements in conformity  with
generally  accepted  accounting  principles and to maintain  accountability  for
assets; (iii) access to assets is permitted only in accordance with management's
general or specific  authorization;  and (iv) the  recorded  accountability  for
assets is compared with existing assets at reasonable  intervals and appropriate
action is taken with respect to any differences. (b) Officers' Certificates. Any
certificate  signed by any  officer of the  Company or any of its  subsidiaries,
including any  Subsidiary  Guarantor,  delivered to the Initial  Purchaser or to
counsel for the Initial Purchaser shall be deemed a representation  and warranty
by the Company to the Initial Purchaser as to the matters covered thereby.

Institutional Buyer over which such person exercises sole investment  discretion
to whom  notice  has been  given  that such sale or  delivery  is being  made in
reliance on Rule 144A, and, in each case, in a transaction  under Rule 144A. (d)
No Liability for  Subsequent  Transfers.  Following the sale of the Units by the
Initial  Purchaser to each  subsequent  purchaser  of the Units  pursuant to the
terms hereof,  the Initial  Purchaser  shall not be liable or responsible to the
Company  for any  losses,  damages or  liabilities  suffered  or incurred by the
Company,  including any losses, damages or liabilities under the Securities Act,

(b)  Amendment  to Offering  Memorandum.  During the period  beginning  the date
hereof  and ending  the date of  completion  of the  offering  of the Units,  as
determined  by the  Initial  Purchaser,  the Company (i) will advise the Initial
Purchaser  promptly of any  proposed  amendment  or  supplement  to the Offering
Memorandum or any document  that would as a result  thereof be  incorporated  by
reference in the Offering  Memorandum,  (ii) will furnish the Initial  Purchaser
with copies of any such  amendment,  supplement  or other  document a reasonable
time in advance of making any such  amendment,  supplement or filing,  and (iii)
will not  effect  such  amendment,  supplement  or filing  without  the  Initial
Purchaser's consent, which consent shall not be unreasonably  withheld.  Neither
the Initial  Purchaser's  consent to, nor its delivery of, any such amendment or
supplement  shall  constitute  a waiver  of any of the  conditions  set forth in
Section 5 hereof.  (c) Notice and Effect of Material  Events.  The Company  will
promptly  notify the Initial  Purchaser of (i) any filing made by the Company of
information  relating to the offering of the Units,  Notes,  Warrants or Warrant
Shares with any securities  exchange or any other  regulatory body in the United
States  or any  other  jurisdiction,  and (ii)  prior to the  completion  of the
offering  of the  Units by the  Initial  Purchaser,  any  material  change in or
affecting,  or any  development  involving a prospective  material  change in or
affecting,  the  earnings or business  of the Company or any  subsidiary  of the
Company  that (A)  makes  any  statement  in the  Offering  Memorandum  false or
misleading or (B) is not disclosed in the Offering Memorandum.  In such event or
if prior to the completion of the offering of the Units any event shall occur as
a result  of which it is  necessary,  in the  reasonable  opinion  of any of the
Company,  its  counsel,  the  Initial  Purchaser  or  counsel  for  the  Initial
Purchaser,  to amend or  supplement  the Offering  Memorandum  in order that the
Offering  Memorandum not include any untrue statement of a material fact or omit
to state a material fact necessary in order to make the  statements  therein not
misleading in the light of the  circumstances  then  existing,  the Company will
forthwith  amend  or  supplement  the  Offering   Memorandum  by  preparing  and
furnishing  to the  Initial  Purchaser  an  amendment  or  amendments  of,  or a
supplement or  supplements  to, the Offering  Memorandum  (in form and substance
satisfactory in the reasonable  opinion of counsel for the Initial Purchaser) so
that, as so amended or supplemented, the Offering Memorandum will not include an
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make  the  statements  therein,  in the  light of the  circumstances
existing at the time it is delivered to a purchaser by the Initial  Purchaser in
connection  with the initial resale of the Units by the Initial  Purchaser,  not
misleading. (d) Transfer Restrictions.  During the period of two years after the
Closing Date, the Company will, upon request,  furnish to the Initial  Purchaser
and any  holder of any of the Units,  the Notes,  the  Warrants  or the  Warrant
Shares a copy of the  restrictions  on transfer  applicable to such Unit,  Note,
Warrant or Warrant Share. (e) Restriction on Repurchases.  The Company will not,
and will cause its  Affiliates  not to,  resell any Units,  Notes,  Warrants  or
Warrant  Shares which have been  acquired by it or them during the period of two
years after the Closing Date and which constitute "restricted  securities" under
Rule  144(a)(3) of the Securities  Act,  otherwise than pursuant to an effective
registration statement under the Securities Act. (f) Investment Company.  During
the period of two years  after the  Closing  Date,  the  Company  will not be or
become an "investment  company"  within the meaning of, nor be or become subject
to regulation under, the Investment  Company Act. (g) Qualification of Units for
Offer and Sale.  The Company and the Subsidiary  Guarantors  will cooperate with
counsel to the Initial  Purchaser to arrange for  qualification of the Units for
sale  under  the  laws  of  such  jurisdictions  as the  Initial  Purchaser  may
reasonably  designate and to maintain such  qualifications  in effect so long as
reasonably required for the distribution of the Units but under no circumstances
for a  period  of less  than  one  year  from  the  date of the  Final  Offering
Memorandum; provided, however, that the Company will not be obligated to qualify
to do  business  as a  foreign  corporation  in any  state in which it is not so
qualified or to file a general consent to service of process in any jurisdiction
in which it is not so qualified  or to subject  itself to taxation in respect of
doing business in any jurisdiction in which it is not otherwise so subject.  The
Company will file such  statements and reports as may be required by the laws of
each jurisdiction in which the Units have been qualified as above provided.
         The  Company  will  also  supply  the  Initial   Purchaser   with  such
information as the Initial  Purchaser  reasonably  believes is necessary for the
determination of the legality of the Units for investment under the laws of such
jurisdictions as the Initial Purchaser may reasonably request.

(h) Payment of Expenses.  The Company agrees to pay (i) the fees and expenses of
its counsel and  accountants  and any  transfer  agents,  conversion  agents and
paying agents;  (ii) the costs in connection with packaging and initial delivery
of the  certificates  evidencing  the Units,  the Notes,  the  Warrants  and the
Warrant Shares and the preparation and printing of the  certificates  evidencing
the Units,  the Notes,  the Warrants and the Warrant Shares,  this Agreement and
the other Transaction Documents, the Preliminary Offering Memorandum,  the Final
Offering  Memorandum  and any  information  provided by the Company  pursuant to
Sections 4(a) and 4(g) above and any other document  relating to the issuance of
the Units;  (iii) the cost of  obtaining  approval  for the trading of the Notes
through the PORTAL Market;  (iv) any fees charged by rating  agencies for rating
the Notes;  (v) the fees and expenses of the Trustee,  including  the legal fees
and expenses of counsel for the Trustee in connection with the Indenture and the

and  expenses of counsel for the Warrant  Agent in  connection  with the Warrant
Agreement  and the  Warrants;  (vii)  any  fees  and  expenses  relating  to the
eligibility of the Units,  Notes,  Warrants and Warrant Shares for clearance and
settlement  through the facilities of the DTC; (viii) the  qualification  of the
Units, Notes,  Warrants and Warrant Shares under the applicable  securities laws
in  accordance  with  Section  4(g)  above,  including  the filing  fees and the
reasonable  fees and  disbursements  of counsel  for the  Initial  Purchaser  in
connection with the Blue Sky Survey and legal investment memoranda; and (ix) all
other costs,  fees and expenses  incident to the  performance of its obligations
hereunder  which are not  specifically  provided for above. If this Agreement is
terminated by the Initial Purchaser in accordance with the provisions of Section
5 hereof,  the Company  shall  reimburse  the Initial  Purchaser  for all of its
reasonable   out-of-pocket   expenses,   including  the   reasonable   fees  and
disbursements  of counsel  for the  Initial  Purchaser,  incurred by the Initial
Purchaser  in making  preparations  for the  purchase,  sale and delivery of the
Units.

(i) Rule 144A(d)(4) Information. So long as any of the Units, Notes, Warrants or
Warrant Shares are "restricted  securities" within the meaning of Rule 144(a)(3)
under the  Securities  Act,  the Company  will either (i) file reports and other
information  with the  Commission  under  Section  13(a) or Section 15(d) of the
Exchange  Act,  or (ii)  during any  period in which it is not  subject to or in
compliance with Sections 13 or 15(d) of the Exchange Act, provide to each holder
of such restricted  securities and to each prospective  purchaser (as designated
by such  holder)  upon  request of such  holder or  prospective  purchaser,  any
information required to be provided by Rule 144A(d)(4) under the Securities Act.
This  covenant  is  intended  to be for  the  benefit  of the  holders,  and the
prospective  purchasers  designated by such  holders,  from time to time of such
restricted  securities.  (j) Eligibility of Units,  Notes,  Warrants and Warrant

be  designated  by  the  Commission,  and  such  other  documents,  reports  and
information as shall be furnished by the Company to the Commission.  (l) No Sale
Requiring Registration. Neither the Company nor any of its Affiliates will offer
for sale,  sell or solicit  offers to buy any other  security (as defined in the
Securities  Act) the offering of which could be integrated  with the sale of the
Units,  Notes or Warrants in a manner that would require the registration of any
of the Units,  Notes or Warrants under the Securities Act. (m) Required Legends.
Each Unit, Note,  Warrant and Warrant Share will bear a legend  substantially in
the form set forth in the  Offering  Memorandum  under the  caption  "Notice  to
Investors"  until such legend shall no longer be necessary or advisable  because
such  Unit,  Note,  Warrant  or  Warrant  Share  is no  longer  subject  to  the
restrictions on transfer described therein.

(n) No Public  Offering  or  Solicitation.  Neither  the  Company nor any of its
Affiliates will offer or sell the Units,  Notes or Warrants in the United States
in any manner  involving a public offering within the meaning of Section 4(2) of
the  Securities Act or by means of any form of general  solicitation  or general
advertising (as those terms are used in Regulation D under the Securities  Act),
including,  but not limited to, (i) any advertisement,  article, notice or other
communication published in any newspaper, magazine or similar media or broadcast
over  television or radio,  or (ii) any seminar or meeting whose  attendees have
been invited by any general solicitation or general advertising.

Rights  Agreement)  and the Exchange Offer  Registration  Statement or the Shelf
Registration  Statement  (as each such term is defined in the Note  Registration
Rights  Agreement),  neither the Company nor any of its Affiliates  will solicit
any offer to buy or offer to sell the Units,  Notes,  Warrants or Warrant Shares
by means of any form of general  solicitation or general advertising (within the
meaning of Rule  502(c) of  Regulation  D) or in any manner  involving  a public
offering within the meaning of Section 4(2) of the Securities Act.

(p) Limitation on Public Offering of Debt Securities. At or prior to the Closing
Time,  the Company will not,  without the prior  written  consent of the Initial
Purchaser, directly or indirectly, offer or sell, or enter into any agreement to
offer or sell,  any debt  securities  issued or guaranteed by the Company with a
maturity of more than one year in any public  offering.  This  limitation is not
applicable  to the public  offering of tax exempt  securities  guaranteed by the
Company or to the Exchange  Notes  referred to in the Note  Registration  Rights
Agreement.  (q) Use of Proceeds.  The Company will use the net proceeds received
by it from  the  sale of the  Units  in the  manner  specified  in the  Offering
Memorandum under the caption "Use of Proceeds".

of counsel for the Initial  Purchaser,  is material or is  necessary to make the
statements  therein,  in the light of the  circumstances  under  which they were
made, not materially misleading.

received from Brown & Wood LLP, counsel for the Initial Purchaser,  such opinion
or opinions,  dated such Closing Date, with respect to the issuance of the Units
and such other related  matters as the Initial  Purchaser  may require,  and the
Company shall have furnished to such counsel such  documents as they  reasonably
request for the purpose of enabling  them to pass upon such  matters.  In giving
such opinion such  counsel may rely,  as to all matters  governed by the laws of
jurisdictions  other than the law of the State of New York,  the  federal law of
the United States and the General Corporation Law of the State of Delaware, upon
the opinions of counsel satisfactory to the Initial Purchaser.  Such counsel may
also state that,  insofar as such opinion involves  factual  matters,  they have
relied,  to the extent they deem proper,  upon  certificates  of officers of the
Company  and  its  subsidiaries  and  certificates  of  public  officials.   (g)
Accountant's Consent;  Comfort Letter. On the date hereof, the Initial Purchaser
shall have received from KPMG LLP, independent auditors of the Company, a letter
dated such date, in form and substance  reasonably  satisfactory  to the Initial
Purchaser, consenting to the incorporation by reference of the audited financial
statements in the Offering  Memorandum and confirming  that they are independent
certified  public  accountants with respect to the Company within the meaning of
the Securities Act and the Rules and Regulations,  and containing statements and
information,  as of the  date  of such  letter  (or,  with  respect  to  matters
involving  changes  or  developments  since  the  respective  dates  as of which
specified  financial  information is given in the Offering  Memorandum,  as of a
date not more  than  five days  prior to the date of such  letter),  of the type
ordinarily  included  in  accountants'  "comfort  letters"  with  respect to the
financial statements and certain financial information contained in the Offering
Memorandum.  (h)  Bring-Down  Comfort  Letter.  On the Closing Date, the Initial
Purchaser  shall have  received from KPMG LLP, a letter dated such date, in form
and substance  reasonably  satisfactory to the Initial Purchaser,  to the effect
that it reaffirms the statements made in the letter  previously  furnished by it
pursuant to Section  5(g)  above,  except that the  specified  date  referred to
therein for the carrying out of procedures  shall be no more than three business
days  prior to the  Closing  Date.  (i)  Officers'  Certificate.  At the time of
execution of this Agreement,  at the time the Offering Memorandum was issued, at
the time any amended or supplemented  Offering  Memorandum was issued and at the
Closing Time, (i)(A) the Offering Memorandum as so amended or supplemented shall
not include an untrue  statement of a material  fact or omit to state a material
fact required to be stated therein or necessary to make the statements  therein,
in the light of the circumstances under which they were made, not misleading and
(B) the documents incorporated by reference in the Offering Memorandum and filed
with the  Commission  prior to the Closing  Time,  except to the extent that any
statement  therein is modified or superseded in the Offering  Memorandum,  as of
the  dates  they were  filed  with the  Commission,  did not  contain  an untrue
statement of a material  fact or omit to state any material  fact required to be
stated therein or necessary to make the statements  therein, in the light of the
circumstances  under which they were made, not misleading;  (ii) there shall not
have been,  since the respective  dates as of which  information is given in the
Offering  Memorandum,  any material  adverse change or any prospective  material
adverse change,  in or affecting  particularly the business or financial affairs
of the  Company  and its  subsidiaries,  including  the  Subsidiary  Guarantors,
considered as one enterprise,  which, in any such case, would, in the opinion of
the Initial  Purchaser,  make it inadvisable to proceed with the offering of the
Units, (iii) no action,  suit or proceeding at law or in equity shall be pending
or, to the  knowledge of the Company,  threatened  against the Company or any of
its subsidiaries, including any Subsidiary Guarantor, other than as set forth in
the Offering Memorandum and no proceedings shall be pending or, to the knowledge
of the  Company,  threatened  against  the  Company or any of its  subsidiaries,
including any  Subsidiary  Guarantor,  before or by any federal,  state or other
commission,  board or  administrative  agency wherein an  unfavorable  decision,
ruling or finding would  reasonably be expected to materially  adversely  affect
the condition  (financial  or  otherwise),  earnings or business  affairs of the
Company and its subsidiaries, including the Subsidiary Guarantors, considered as
one  enterprise,  other than as set forth in the Offering  Memorandum,  (iv) the
Company and the  Subsidiary  Guarantors  shall have complied with all agreements
and  satisfied all  conditions  set forth herein on its part to be performed and
satisfied at or prior to the Closing Time and (v) the other  representations and
warranties  of the Company and the  Subsidiary  Guarantors  set forth in Section
1(a) hereof shall be accurate as though  expressly made at and as of the time of
execution of this  Agreement  and the Closing  Time,  as the case may be. At the
Closing Time,  the Initial  Purchaser  shall have received a certificate  of the
Chairman, Chief Executive Officer and President of the Company and the Executive
Vice President-Acquisitions, Chief Financial Officer, Treasurer and Secretary of
the  Company,  dated as of the Closing  Time,  to such  effect.  (j) No Material

Memorandum was issued and at the Closing Time, there shall not have occurred any
of the following  (i) the Company  shall have failed,  refused or been unable to
perform any  agreement  on its part to be performed  hereunder,  (ii) trading in
securities generally on the New York Stock Exchange, the American Stock Exchange
or the over-the-counter market shall have been suspended or minimum prices shall
have  been  established  on  either  of such  exchanges  or such  market  by the
Commission or such exchange or other  regulatory body or governmental  authority
having  jurisdiction,  (iii) a banking moratorium is declared by either Federal,
Commonwealth of  Massachusetts  or New York State  authorities,  (iv) the United
States  becomes  engaged in hostilities or there is an escalation of hostilities
involving the United States or there is a declaration of a national emergency or
war by the United  States,  (v) there  shall  have been such a material  adverse
change in general economic,  political or financial conditions, or the effect of
international  or national  conditions  on the  financial  markets in the United
States shall be such, as to, in the judgment of the Initial  Purchaser,  make it
inadvisable or  impracticable to proceed with the offering of the Units, or (vi)
the Company  shall have  sustained  any loss by fire,  flood,  accident or other
calamity,  or become a party to or the subject of any  litigation or proceeding,
which is materially adverse to the Company,  or there shall have been a Material
Adverse Effect or other material  adverse  change in the  governmental  affairs,
operations, business, key personnel, capitalization,  financial condition or net
worth of the Company, whether or not arising in the ordinary course of business,
which in the case of (i)  through  (vi)  above,  in the  judgment of the Initial
Purchaser,  shall render it  impracticable  or  inadvisable  to proceed with the
offering  of the Units.  (k) PORTAL.  The Notes shall have been  approved by The
National  Association of Securities Dealers,  Inc. as being eligible for trading
in the PORTAL Market and the Units,  Notes and Warrants shall have been declared
eligible for clearance and settlement  through The Depository Trust Corporation.
(l) Note Registration  Rights Agreement.  The Note Registration Rights Agreement
shall have been  executed  and  delivered  and be in form,  scope and  substance
reasonably  satisfactory  to the Initial  Purchaser.  (m)  Warrant  Registration
Rights  Agreement.  The Warrant  Registration  Rights  Agreement shall have been
executed  and  delivered  and  be  in  form,  scope  and  substance   reasonably
satisfactory to the Initial Purchaser. (n) Additional Documents. The Company and
each Subsidiary Guarantor shall furnish to the Initial Purchaser and counsel for
the Initial Purchaser  conformed copies of any opinions,  certificates,  letters
and other  documents  in such  number as they shall  reasonably  request for the
purpose of enabling them to pass upon the issuance and sale of the Units and the
issuance of the Notes and  Warrants as  contemplated  in this  Agreement  and in
order to evidence the accuracy and  completeness of any of the  representations,
warranties or statements of the Company or of the Subsidiary Guarantors,  or the
fulfillment  of any of the  conditions,  herein  contained.  All such  opinions,
certificates,  letters and documents  shall be in compliance with the provisions
hereof only if they are reasonably satisfactory in form and substance to counsel
for the Initial Purchaser.

         If any of the  conditions  specified  in this  Section 5 shall not have
been  fulfilled when and as required by this  Agreement,  this Agreement and all
obligations  of the Initial  Purchaser  hereunder  may be canceled at, or at any
time  prior to, the  Closing  Date by the  Initial  Purchaser,  except  that the
provisions  of Section  4(h),  Section 6 and  Section 7 shall  survive  any such
termination and remain in full force and effect.  Any such cancellation shall be
without  liability  of the  Initial  Purchaser  to the  Company.  Notice of such
cancellation  shall be given to the  Company  in  writing,  or by  telegraph  or
telephone and confirmed in writing.

SECTION 6Indemnification and Contribution.

(a) Indemnification of Initial Purchaser. The Company and each of the Subsidiary
Guarantors, jointly and severally, shall indemnify and hold harmless the Initial
Purchaser,  its directors,  officers and employees and each person,  if any, who
controls  the  Initial  Purchaser  within  the  meaning  of  Section  15 of  the
Securities Act or Section 20 of the Exchange Act:

(i) from and against any and all loss, liability,  claim, damage,  action and 
expense whatsoever,  as incurred,  insofar as such  loss,  liability,  claim,  
damage,  action or expense  arises out of, or is based upon,  any untrue  
statement or alleged  untrue  statement  of a material  fact  included in the  
Preliminary Offering  Memorandum  or the Final  Offering  Memorandum,  or any  
amendment or  supplement  thereto,  or the omission  or  alleged  omission  to  
state in the  Preliminary  Offering  Memorandum  or the  Final  Offering
Memorandum,  or any amendment or  supplement  thereto,  any material  fact  
required to be stated  therein or necessary  to make the  statements  therein, 
in light of the  circumstances  in which  they were  made,  not misleading;

(ii)  against any and all loss,  liability,  claim,  damage,  action and expense
whatsoever,  as  incurred,  to  the  extent  of the  aggregate  amount  paid  in
settlement of any litigation, or investigation or proceeding by any governmental
agency or body,  commenced or threatened,  or of any claim whatsoever based upon
any such untrue  statement or omission,  or any such alleged untrue statement or
omission;  provided that (subject to Section 6(d) below) any such  settlement is
effected with the written consent of the Company; and
                  (iii)  against  any  and  all  expense  whatsoever  (including
         reasonable  fees and  disbursements  of counsel  chosen by the  Initial
         Purchasers)   reasonably   incurred  in  investigating,   preparing  or
         defending against any litigation, or investigation or proceeding by any
         governmental  agency or body,  commenced  or  threatened,  or any claim
         whatsoever  based upon any such untrue  statement or  omission,  or any
         such alleged untrue statement or omission,  to the extent that any such
         expense is not paid under subparagraph (i) or (ii) above;

                                       12
<PAGE>

 provided,  however, that the Company and the Subsidiary Guarantors shall not be
liable in any such case to the  extent  that any such  loss,  liability,  claim,
damage,  action or expense arises out of or is based upon, any untrue  statement
or  alleged  untrue  statement  or  omission  or  alleged  omission  made in the
Preliminary  Offering  Memorandum  or  the  Final  Offering  Memorandum,  or any
amendment or supplement thereto, in reliance upon and in conformity with written
information  furnished to the Company by the Initial Purchaser  specifically for
inclusion therein. The foregoing indemnification with respect to any Preliminary
Offering  Memorandum or Final Offering Memorandum shall not inure to the benefit
of the  Initial  Purchaser  (or to the  benefit of any person  controlling  such
Initial  Purchaser) if the person  asserting any such losses,  claims,  damages,
liabilities  or expenses was not sent or delivered a copy of the Final  Offering
Memorandum (or the Final Offering  Memorandum as amended or  supplemented) at or
prior to the written confirmation of the sale of Units to such person and if the
untrue  statement or omission of a material fact  contained in such  Preliminary
Offering Memorandum was corrected in the Final Offering Memorandum (or the Final
Offering  Memorandum as amended or  supplemented)  unless such  corrected  Final
Offering  Memorandum  was not sent or  delivered  because the Company  failed to
timely provide the Initial  Purchaser with  sufficient  copies of such corrected
Final Offering  Memorandum.  The foregoing indemnity agreement is in addition to
any liability which the Company and the Subsidiary Guarantors may otherwise have
to the Initial  Purchaser or to any officer,  employee or controlling  person of
the Initial Purchaser.

(b)  Indemnification  of the Company.  The Initial Purchaser shall indemnify and
hold  harmless the Company,  its  directors,  officers  and  employees  and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities  Act or Section 20 of the Exchange  Act, from and against any and all
loss,  liability,  claim,  damage,  action and expense described in Section 6(a)
above,  as  incurred,  but in each  case  only to the  extent  that  the  untrue
statement or alleged  untrue  statement or omission or alleged  omission made in
the  Preliminary  Offering  Memorandum or the Final Offering  Memorandum (or any
amendment or  supplement  thereto) was made in reliance  upon and in  conformity
with written  information  concerning  such Initial  Purchaser  furnished to the
Company by First Albany Corporation specifically for inclusion therein.

(c)  Actions  Against  Parties;  Notification.  Promptly  after  receipt  by  an
indemnified  party  under  this  Section  6  of  notice  of  any  claim  or  the
commencement of any action,  the indemnified  party shall, if a claim in respect
thereof is to be made  against  the  indemnifying  party  under this  Section 6,
notify the  indemnifying  party in writing of the claim or the  commencement  of
that  action;  provided,  however,  that the failure to notify the  indemnifying
party  shall not  relieve  it from any  liability  which it may have  under this
Section  6,  except to the  extent  it has been  materially  prejudiced  by such
failure,  or from  any  liability  which  it may  have to an  indemnified  party
otherwise than under this Section 6. In the case of parties indemnified pursuant
to Section 6(a) above,  counsel to the indemnified  parties shall be selected by
the  Initial  Purchaser,  and,  in the case of parties  indemnified  pursuant to
Section 6(b) above,  counsel to the indemnified parties shall be selected by the
Company. An indemnifying party may participate at its own expense in the defense
of any such action;  provided,  however,  that counsel to the indemnifying party
shall not (except with the consent of the indemnified  party) also be counsel to
the indemnified party. In no event shall the indemnifying  parties be liable for
fees and  expenses of more than one counsel (in  addition to any local  counsel)
separate from their own counsel for all  indemnified  parties in connection with
any  one  action  or  separate  but  similar  or  related  actions  in the  same
jurisdiction  arising out of the same general  allegations or circumstances.  No
indemnifying   party  shall  (i)  without  the  prior  written  consent  of  the
indemnified parties (which consent shall not be unreasonably withheld) settle or
compromise  or consent to the entry of any judgment  with respect to any pending
or  threatened   claim,   action,   suit  or  proceeding  in  respect  of  which
indemnification  or  contribution  may be sought  hereunder  (whether or not the
indemnified  parties  are actual or  potential  parties to such claim or action)
unless such  settlement,  compromise  or consent (A)  includes an  unconditional
release of each indemnified  party from all liability arising out of such claim,
action,  suit or  proceeding  and (B) does not include a  statement  as to or an
admission  of fault,  culpability  or a failure  to act by or on  account of any
indemnified  party,  or (ii) be liable  for any  settlement  of any such  action
effected  without its written  consent (which consent shall not be  unreasonably
withheld), but if settled with the consent of the indemnifying party or if there
be a final judgment of the plaintiff in any such action,  the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. (d) Contribution. If
the indemnification provided for in this Section 6 is for any reason unavailable
to or insufficient to hold harmless an indemnified party in respect of any loss,
claim,  damage or  liability,  or any action in  respect  thereof,  referred  to
therein,  then  each  indemnifying  party  shall  in lieu of  indemnifying  such
indemnified party,  contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof,  (i) in such  proportion  as is  appropriate  to reflect  the  relative
benefits  received by the Company and the Subsidiary  Guarantors on the one hand
and the Initial  Purchaser on the other from the offering of the Units  pursuant
to this Agreement or (ii) if the allocation  provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault  of the  Company  and the  Subsidiary  Guarantors  on the one hand and the
Initial Purchaser on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant  equitable  considerations.  The relative benefits
received by the Company and the  Subsidiary  Guarantors  on the one hand and the
Initial  Purchaser on the other with respect to such offering shall be deemed to
be in the same  proportion  as the total net proceeds from the sale of the Units
to the  Initial  Purchaser  under this  Agreement  (before  deducting  expenses)
received  by the  Company  bear to the total  discount  received  by the Initial
Purchaser with respect to the Units purchased under this Agreement, in each case
as set forth on the cover of the Final Offering  Memorandum.  The relative fault
of the Company  and the  Subsidiary  Guarantors  on the one hand and the Initial


                                       13
<PAGE>


Purchaser on the other hand shall be  determined  by  reference  to, among other
things,  whether any such untrue or alleged untrue  statement of a material fact
or omission or alleged  omission to state a material fact relates to information
supplied by the Company or the Initial Purchaser,  the intent of the parties and
their relative  knowledge,  access to information  and opportunity to correct or
prevent such statement or omission.  The Company, the Subsidiary  Guarantors and
the  Initial  Purchaser  agree  that it  would  not be  just  and  equitable  if
contributions  pursuant to this Section 6(d) were to be  determined  by pro rata
allocable or by any other method of allocation  which does not take into account
the equitable  considerations  referred to herein. The amount paid or payable by
an indemnified  party as a result of the loss,  claim,  damage or liability,  or
action in  respect  thereof,  referred  to above in this  Section  6(d) shall be
deemed  to  include,  for  purposes  of this  Section  6(d),  any legal or other
expenses  reasonably  incurred  by such  indemnified  party in  connection  with
investigating,   preparing  or  defending   against  any   litigation,   or  any
investigation  or proceeding by any  governmental  agency or body,  commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged  omission.  Notwithstanding  the  provisions of
this Section 6(d), the Initial Purchaser shall not be required to contribute any
amount  in excess  of the  amount  by which  the total  price at which the Units
purchased  and resold by it exceeds the amount of any damages  which the Initial
Purchaser has otherwise  paid or become liable to pay by reason of any untrue or
alleged untrue  statement or omission or alleged  omission.  No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation. Each party entitled to contribution
agrees that upon the service of a summons or other initial legal process upon it
in any action  instituted  against it in  respect to which  contribution  may be
sought,  it shall  promptly give written  notice of such service to the party or
parties from whom contribution may be sought, but the omission so to notify such
party or  parties  of any such  service  shall not  relieve  the party from whom
contribution may be sought for any obligation it may have hereunder or otherwise
(except  as  specifically  provided  in Section  6(c)  above).  (e)  Information
Provided by Initial  Purchaser.  The Initial Purchaser  confirms and the Company
and the Subsidiary  Guarantors  acknowledge  that the statements with respect to
the Units,  Notes and Warrants by the Initial  Purchaser  set forth on the cover
page of, and the text appearing under the caption "Plan of Distribution" in, the
Offering  Memorandum  constitute the only  information  concerning  such Initial
Purchaser  furnished  in writing to the  Company by or on behalf of the  Initial
Purchaser  specifically  for  inclusion  in  the  Offering  Memorandum.  SECTION
7Survival  of  Representations,   Warranties  and  Obligations.  The  respective
indemnities, agreements, representations, warranties and other statements of the
Company,  the Subsidiary  Guarantors or any of their officers and of the Initial
Purchaser  set  forth  in or made in  certificates  delivered  pursuant  to this
Agreement will remain in full force and effect,  regardless of any investigation
made by or on behalf of the  Initial  Purchaser,  the  Company,  the  Subsidiary
Guarantors or any of their respective representatives,  officers or directors or
any person who controls the Company or the Initial  Purchaser within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall
survive delivery of and payment for the Units.

SECTION 8. Notices. All communications  hereunder will be in writing and will be
deemed to have been duly given if mailed or  transmitted by any standard form of
telecommunication.  Notices to the Initial  Purchaser shall be directed to First
Albany Corporation at 30 South Pearl Street, Albany, New York 12201,  Attention:
Legal Department  (facsimile:  (518) 447-8557),  with a copy, in the case of any
notice  pursuant  to Section  6(c),  to Stephen  Wink,  Esquire;  notices to the
Company shall be directed to it at Waste Systems International,  Inc., Lexington
Office Park, 420 Bedford  Street,  Lexington,  Massachusetts  02173,  Attention:
President  (facsimile:  (781) 862-2929).  SECTION 9. Parties.  This Agreement is
made solely for the benefit of the Initial  Purchaser,  the Company  and, to the
extent  expressed,  any person who controls the Company or the Initial Purchaser
within the meaning of Section 15 of the  Securities  Act, and the  directors and
officers of the Company and its respective executors, administrators, successors
and  assigns  and no other  person  shall  acquire or have any right under or by
virtue of this  Agreement.  The term  "successors and assigns" shall not include
any purchaser,  as such purchaser,  from the Initial Purchaser of the Units. All
of their  obligations  hereunder  are several and not joint.  SECTION 10. Entire
Agreement.  This  Agreement  is complete,  reflects the entire  agreement of the
parties with respect to its subject matter,  and supersedes all previous written
or oral  negotiations,  commitments  and writings  between the parties hereto in
respect of the transactions  contemplated  herein. No promise,  representations,
understandings,  warranties and agreements  have been made by any of the parties
hereto  except as referred to herein and all  inducements  to the making of this
Agreement relied upon by either party hereto have been expressed herein. SECTION
11.  Governing  Law.  THIS  AGREEMENT  SHALL BE  GOVERNED  BY AND  CONSTRUED  IN
ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE
AND TO BE PERFORMED WHOLLY WITHIN SUCH JURISDICTION.  SECTION 12.  Counterparts.
This  Agreement  may be  executed in any number of  counterparts,  each of which
shall be deemed an original but all of which shall  constitute  one and the same
instrument.  SECTION 13. Effect of Headings. The Section headings herein and the
Table of Contents are for convenience only and shall not affect the construction
hereof.

         (ix)     The  Warrant  Shares to be issued by  Company  pursuant  to 
                  the  Warrant  Agreement  have been duly authorized  for 
                  issuance and sale,  and,  when issued and  delivered by the 
                  Company  pursuant to the Warrant  Agreement,  will be validly 
                  issued  and fully paid and  non-assessable.  The  Company  has
                  reserved and  available,  out of the aggregate of its  
                  authorized  but unissued  Common Stock or its authorized  and

                  the exercise of all  outstanding  Warrants  (without  giving
                  effect to any future splits,  dividends or similar events with
                  respect to the Common Stock,  none of which,  to our knowledge
                  are currently  contemplated by the Company).  The form of 
                  certificate  used to evidence the Warrant  Shares  complies in
                  all material  respects  with all  applicable  statutory
                  requirements,  with any  applicable  requirements  of the
                  charter and  by-laws of the  Company.  The issuance of the 
                  Warrant  Shares is not subject to the  preemptive or other any
                  statutory  preemptive rights or preemptive  rights in the  
                  Certificate of  Incorporation or By-laws of the Company or, to
                  our knowledge, similar rights of any securityholder of the 
                  Company.

         (x)      The Units, Notes,  Warrants and Common Stock and the Indenture

                  material respects to the descriptions thereof contained in the

                  and fairly  present in all material  respects the  information
                  required to be shown therein.

         (xii)    All  descriptions in the Offering  Memorandum of contracts and
                  other documents to which the Company or its subsidiaries are a

         We have participated in the preparation of the Offering  Memorandum and
have participated in discussions with your representatives, those of counsel for
the Initial  Purchaser,  and those of the Company and its  accountants.  We have
also reviewed operating permits for the Company's currently operating facilities
and  facilities  proposed to commence  operations  as  described in the Offering
Memorandum and a limited number of environmental site assessments for certain of
such facilities,  in each case in the form provided to us by the Company, and we
have  participated  in  conversations  with the Company's  management  regarding
overall environmental compliance. On the basis of the information that we gained
in the course of the performance of the services  referred to above,  considered
in the light of our  understanding  of the  applicable law and the experience we
have gained  through our  practice in offerings of the type made by the Offering
Memorandum,  we confirm to you that  nothing  that came to our  attention in the
course of such review has caused us to believe (A) that the Offering  Memorandum
or any amendment or supplement  thereto  (except for  financial  statements  and
schedules and other financial data included or incorporated by reference therein
or omitted therefrom, as to which we make no statement),  as of the date of such
Offering Memorandum or any such amendment or supplement and on the Closing Date,
included or includes an untrue  statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements  therein,  in
the light of the circumstances under which they were made, not misleading or (B)
that the  documents  incorporated  by reference in the Offering  Memorandum  and
filed with the  Commission  prior to the  Closing  Date  (except  for  financial
statements and schedules and other  financial data included or  incorporated  by
reference therein or omitted  therefrom,  as to which we make no statement,  and
except to the extent that any statement therein is modified or superseded in the
Offering  Memorandum or by a subsequent  document  filed with the Commission and
incorporated by reference in the Offering Memorandum), and as of the date hereof
contained or contain an untrue  statement of a material  fact or omitted or omit
to state any material  fact  required to be stated  therein or necessary to make
the  statements  therein  not  misleading.   The  limitations  inherent  in  the
independent  verification of factual matters and the character of determinations
involved in the offering  process are such,  however,  that we do not assume any
responsibility  for the  accuracy,  completeness  or fairness of the  statements
contained in the Offering Memorandum or the documents  incorporated by reference
therein   except  for  those  made  under  the  captions   "Business--Government
Regulation,"   "Certain  Federal  Income  Tax  Considerations"  and  "Notice  to
Investors" in the Offering Memorandum,  insofar as such statements  constitute a
summary of documents referred to therein or matters of law.

         In rendering such opinion,  we have relied,  as to matters of fact (but
not as to legal  conclusions),  to the extent we deem proper, on certificates of
responsible officers of the Company and public officials.

         (i)      The  Company is duly  qualified  as a foreign  corporation  to
                  transact business and is in good standing in each jurisdiction
                  listed on  Appendix I attached  hereto,  which  jurisdictions,
                  based on a certificate  of the Company,  constitute all of the
                  jurisdictions  in which the Company owns or leases property or
                  otherwise conducts its business.

         (ii)     The authorized,  issued and  outstanding  capital stock of the
                  Company  is as set forth in the  Offering  Memorandum  and the
                  shares of issued and outstanding  capital stock of the Company
                  have been duly  authorized  and  validly  issued and are fully
                  paid and non-assessable; and none of the outstanding shares of
                  capital  stock of the Company was issued in  violation  of any
                  statutory  preemptive  rights  or  preemptive  rights  in  the
                  Certificate of  Incorporation  or By-laws or, to my knowledge,
                  similar rights of any securityholder of the Company.

         (iii)    Each direct and indirect  subsidiary of the Company,  
                  including each  Subsidiary  Guarantor,  other
                  than Mostoller  Landfill has been duly incorporated and is 
                  validly existing as a corporation in good
                  standing under the laws of the jurisdiction of its 
                  incorporation,  has corporate power and authority
                  to own,  lease and operate its  properties  and to conduct 
                  its business as described in the Offering Memorandum  and is 
                  duly  qualified  as a foreign  corporation  to transact     
                  business  and is in good standing  in each jurisdiction listed

                  hereto,  which  jurisdictions,  based  on a  certificate  of  
                  the  Company,  constitute  all  of the jurisdictions  in which
                  such subsidiary owns or leases property or otherwise  conducts
                  its business; except as otherwise disclosed in the Offering 
                  Memorandum,  all of the issued and outstanding capital
                  stock of each direct and indirect  subsidiary of the Company, 
                  including each Subsidiary  Guarantor,
                  has been duly authorized and validly issued,  is fully paid 
                  and  non-assessable  and, to the best of
                  my  knowledge,  is owned by the  Company,  directly or through

                  security  interest,  other than security interests granted by
                  the Company under the Credit Facility; none of the outstanding
                  shares  of  capital  stock of any  subsidiary,  including  any

                  Certificate of  Incorporation or By-laws or, to my knowledge, 
                  similar rights of any  securityholder of such subsidiary.

         (iv)     To the best of my  knowledge,  based upon a  certificate  of 
                  the Company,  and except as would not, individually or in the 
                  aggregate,  result in a Material Adverse Effect,  neither the 
                  Company nor any subsidiary, including any Subsidiary Guarantor
                  is in violation of its charter or by-laws and no
                  default  by the  Company  or any  subsidiary  exists in the 
                  due  performance  or  observance  of any material  obligation,
                  agreement,  covenant  or  condition  contained  in any 
                  contract,  indenture, mortgage,  loan  agreement,  note,  
                  lease or other agreement or instrument  that is  described or
                  referred to in the  Offering  Memorandum  or filed as an 
                  exhibit to the  documents  incorporated  by
                  reference in the Offering Memorandum.

         (v)      To  the  best  of  my  knowledge  and  except  as  would  not,
                  individually or in the aggregate, result in a Material Adverse
                  Effect there is no Environmental Claim, pending or, threatened
                  against the Company or any of its subsidiaries,  including any
                  Subsidiary Guarantor,  or any person or entity whose liability
                  for  any  Environmental  Claim  the  Company  or  any  of  its
                  subsidiaries  has retained or assumed either  contractually or
                  by operation of law.

         (vi)     There is not pending or, to the best of my  knowledge,  
                  threatened  any action,  suit,  proceeding, inquiry  or  
                  investigation,  to which the  Company  or any  subsidiary  
                  is a party,  or to which the property  of the  Company  or any
                  subsidiary  is  subject,  before  or  brought  by  any  court 
                  or governmental agency or body, domestic or foreign,  which 
                  might reasonably be expected to result in a
                  Material  Adverse Effect,  or which might  reasonably be 
                  expected to materially and adversely affect
                  the  properties  or assets  thereof or the  consummation  of
                  the  transactions  contemplated  in the Purchase  Agreement,  
                  Note Registration  Rights Agreement,  Warrant  Registration 
                  Rights Agreement,  Warrant Agreement or Indenture, or the 
                  performance by the Company of its obligations thereunder.

         (vii)    To  the  best  of my  knowledge,  and  except  as  would  not,
                  individually or in the aggregate, result in a Material Adverse
                  Effect,  neither the Company nor any  subsidiary  has received
                  any  notice  of  proceedings  relating  to the  revocation  or
                  modification of any Governmental Licenses.

         In rendering  such opinion,  I have relied,  as to matters of fact (but
not as to legal  conclusions),  to the extent I deem proper,  on certificates of
responsible officers of the Company and public officials.

incurred  any  Indebtedness  since the  beginning of such period and through the
date of  determination  of the  Consolidated  Fixed Charge  Coverage  Ratio that
remains  outstanding or if the transaction  giving rise to the need to calculate
the Consolidated Fixed Charge Coverage Ratio is an incurrence of Indebtedness or

be calculated after giving effect on a pro forma basis to (1) such  Indebtedness
as if such  Indebtedness  had been  incurred  on the  first  day of such  period
(provided  that if such  Indebtedness  is  incurred  under  a  revolving  credit

purposes of this  calculation)  and (2) the discharge of any other  Indebtedness
repaid, repurchased,  defeased or otherwise discharged with the proceeds of such
new  Indebtedness  as if such  discharge  had  occurred on the first day of such
period,  (B) if since the  beginning  of such  period  any  Indebtedness  of the
Company or its Restricted Subsidiaries has been repaid, repurchased, defeased or
otherwise  discharged  (other  than  Indebtedness  under a  revolving  credit or
similar   arrangement  unless  such  revolving  credit   Indebtedness  has  been
permanently repaid and the underlying  commitment  terminated and not replaced),
Consolidated  Fixed Charges for such period shall be calculated after giving pro
forma  effect  thereto as if such  Indebtedness  had been  repaid,  repurchased,
defeased or otherwise  discharged on the first day of such period,  (C) if since
the beginning of such period the Company or any of its  Restricted  Subsidiaries
shall have made any Asset Sale, Adjusted EBITDA for such period shall be reduced
by an amount  equal to the Adjusted  EBITDA (if  positive)  attributable  to the
assets  which are the subject of such Asset Sale for such period or increased by
an amount equal to the Adjusted  EBITDA (if negative)  attributable  thereto for
such period,  Consolidated Fixed Charges for such period shall be (i) reduced by
an  amount  equal  to  the  Consolidated  Fixed  Charges   attributable  to  any
Indebtedness  of the  Company  or any of  its  Restricted  Subsidiaries  repaid,
repurchased,  defeased or otherwise  discharged  with respect to the Company and
its continuing  Restricted  Subsidiaries  in connection with such Asset Sale for
such period (or if the Capital Stock of any  Restricted  Subsidiary is sold, the
Consolidated  Interest for such period directly attributable to the Indebtedness
of such  Restricted  Subsidiary  to the extent the  Company  and its  continuing
Restricted  Subsidiaries are no longer liable for such  Indebtedness  after such
sale) and (ii) increased by interest income attributable to the assets which are
the subject of such Asset Sale for such  period,  (D) if since the  beginning of

otherwise)  shall have made an Investment in any  Restricted  Subsidiary (or any
Person  which  becomes  a  Restricted  Subsidiary  as a  result  thereof)  or an
acquisition  of assets  occurring in  connection  with a  transaction  causing a
calculation to be made hereunder which  constitutes all or substantially  all of
an operating unit of a business,  Adjusted EBITDA and Consolidated Fixed Charges
for such  period  shall be  calculated  after  giving pro forma  effect  thereto
(including  the  incurrence  of  any  Indebtedness)  as if  such  Investment  or
acquisition  occurred  on the  first  day of such  period,  and (E) if since the
beginning  of such  period any Person  (that  subsequently  became a  Restricted
Subsidiary  of the  Company or was merged  with or into the Company or any other
Restricted  Subsidiary  since the  beginning of such period) shall have made any
Asset Sale,  Investment  or  acquisition  of assets that would have  required an
adjustment  pursuant  to  clause  (C) or (D) above if made by the  Company  or a
Restricted Subsidiary during such period, Adjusted EBITDA and Consolidated Fixed
Charges  for such  period  shall be  calculated  after  giving pro forma  effect
thereto as if such Asset Sale,  Investment  or  acquisition  had occurred on the
first day of such  period.  For the  purposes of this  definition,  whenever pro
forma effect is to be given to an acquisition of assets, the amount of income or
earnings  relating  thereto  and  the  amount  of  Consolidated   Fixed  Charges
associated with any Indebtedness incurred in connection therewith, the pro forma
calculations  shall be determined  in good faith by a  responsible  financial or
accounting officer of the Company.  If any Indebtedness bears a floating rate of
interest  and is being  given pro forma  effect,  the  interest  expense on such
Indebtedness  shall  be  calculated  as if the  rate in  effect  on the  date of
determination had been the applicable rate for the entire period.

debt discount,  (b) the net cash payments, if any, under interest rate contracts
(including amortization of discounts),  (c) the interest portion of any deferred
payment  obligation,  (d) accrued interest,  plus (ii) the interest component of
the Capital  Lease  Obligations  paid,  accrued  and/or  scheduled to be paid or
accrued by the Company and its Restricted  Subsidiaries  during such period,  of
the Company and its Restricted Subsidiaries,  plus (iii) all cash dividends paid
during such period by the Company and its Restricted  Subsidiaries  with respect
to any Preferred Stock and  Disqualified  Stock, in each case as determined on a
consolidated  basis in  accordance  with  GAAP;  plus (iv) all  interest  on any
Indebtedness  of any person  guaranteed by the Company or any of its  Restricted
Subsidiaries;  provided,  that Consolidated  Fixed Charges shall not include (x)
the  amortization  of  debt  issuance  costs  and  (y) the  fixed  charges  of a

income (or loss) of the Company and its  Restricted  Subsidiaries  allocable  to
interests in unconsolidated  Persons or Unrestricted  Subsidiaries,  except that

included in Consolidated  Net Income to the extent of the amount of dividends or
distributions  actually paid to the Company or its  Restricted  Subsidiaries  by
such Person or Subsidiary during such period,  (iii) net income (or loss) of any
Person  combined  with the Company or any of its  Restricted  Subsidiaries  on a
"pooling of  interests"  basis  attributable  to any period prior to the date of
combination,  (iv)  net  gain  or loss  in  respect  of any  sale,  transfer  or

notice,  consent,  waiver or other action provided by this Indenture to be given
or taken by Holders may be embodied in and evidenced by one or more  instruments
of  substantially  similar  tenor  signed by such Holders in person or by agents
duly  appointed  in  writing   (including  but  not  limited  to  an  electronic
transmission of an agent's message or other consent pursuant to the Depositary's
Automated Tender Offer Program or any similar procedure);  and, except as herein
otherwise  expressly  provided,  such action  shall become  effective  when such
instrument or  instruments  are delivered to the Trustee and, where it is hereby
expressly  required,  to the Company.  Such  instrument or instruments  (and the
action embodied therein and evidenced  thereby) are herein sometimes referred to
as the "Act" of the Holders  signing such  instrument or  instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient  for any purpose of this  Indenture and conclusive in favor of the
Trustee and the Company if made in the manner provided in this Section.

                  (b)......The  fact and date of the  execution by any Person of
any such  instrument  or writing may be proved by the  affidavit of a witness of
such  execution  or  by a  certificate  of a  notary  public  or  other  officer
authorized  by law  to  take  acknowledgments  of  deeds,  certifying  that  the
individual signing such instrument or writing  acknowledged to him the execution
thereof. Where such execution is by a signer acting in a capacity other than his
individual  capacity,  such  certificate  or  affidavit  shall  also  constitute
sufficient  proof of  authority.  The fact and date of the execution of any such
instrument or writing,  or the authority of the Person  executing the same,  may
also be proved in any other manner that the Trustee deems sufficient.

                  (c)......The principal  amount and serial numbers of 
Securities held by any Person,  and the date of holding the same shall be proved
by the Security Register.

                  (d)......If  the  Company  shall  solicit  from the Holders of
Securities  any request,  demand,  authorization,  direction,  notice,  consent,
waiver or other Act, the Company  may, at its option,  by or pursuant to a Board
Resolution,  fix in  advance  a record  date for the  determination  of  Holders
entitled  to  give  such  request,  demand,  authorization,  direction,  notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding  TIA Section  316(c),  such record date shall be the record date
specified  in or  pursuant to such Board  Resolution,  which shall be a date not
earlier  than  the date 30 days  prior  to the  first  solicitation  of  Holders
generally in connection  therewith and not later than the date such solicitation
is  completed.   If  such  a  record  date  is  fixed,  such  request,   demand,
authorization,  direction,  notice,  consent,  waiver  or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such  record date shall be deemed to be Holders for the  purposes of
determining   whether  Holders  of  the  requisite   proportion  of  Outstanding
Securities  have  authorized  or agreed or  consented to such  request,  demand,
authorization,  direction,  notice,  consent,  waiver or other Act, and for that
purpose the  Outstanding  Securities  shall be computed as of such record  date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective  pursuant
to the  provisions  of this  Indenture  not later than eleven  months  after the
record date.

<PAGE>

                  (e)......Any  request,   demand,   authorization,   direction,
notice,  consent,  waiver or other Act of the Holder of any Security  shall bind
every future Holder of the same Security and the Holder of every Security issued
upon the  registration  of transfer  thereof or in exchange  therefor or in lieu
thereof in respect  of  anything  done,  omitted or  suffered  to be done by the
Trustee or the  Company in  reliance  thereon,  whether or not  notation of such
action is made upon such Security.

                  (f)......For  all  purposes  of this  Indenture,  all  Initial
Securities  and  Exchange  Securities  shall  vote  together  as one  series  of
Securities under this Indenture.

                  SECTION 105.      Notices, Etc., to Trustee, Company.

                  Any request, application,  demand,  authorization,  direction,
notice,  consent,  waiver  or Act of  Holders  or  other  document  provided  or
permitted  by this  Indenture to be made upon,  given or furnished  to, or filed
with,

                  (a) the  Trustee  by any  Holder  or by the  Company  shall be
         sufficient  for every purpose  hereunder if made,  given,  furnished or
         filed in writing  and hand  delivered  or mailed,  first-class  postage
         prepaid,  to or  with  the  Trustee  at  its  Corporate  Trust  Office,
         Attention:  Corporate  Trust  Department,  or sent by  facsimile to the
         Trustee at (212) 858-2952 (with receipt confirmed by telephone at (212)
         858-2000); or

                  (b) the  Company  by the  Trustee  or by any  Holder  shall be
         sufficient  for  every  purpose   hereunder  (unless  otherwise  herein
         expressly  provided)  if in writing  and  mailed,  first-class  postage
         prepaid, to the Company addressed to it at Waste Systems International,
         Inc.,   Lexington   Office  Park,   420  Bedford   Street,   Lexington,
         Massachusetts 02173 Attention:  President,  or sent by facsimile to the
         Company at (781) 862-2929 (with receipt confirmed by telephone at (781)
         862-3000),  or at any other  address  or  facsimile  number  previously
         furnished in writing to the Trustee by the Company.

                  SECTION 106.      Notice to Holders; Waiver.

                  Where  this  Indenture  provides  for  notice  of any event to
Holders by the Company or the Trustee,  such notice shall be sufficiently  given
(unless  otherwise  herein  expressly   provided)  if  in  writing  and  mailed,
first-class  postage prepaid, to each Holder affected by such event, at his last
address as it appears in the Security Register,  not later than the latest date,
and not  earlier  than the  earliest  date,  prescribed  for the  giving of such
notice.  In any case  where  notice to  Holders  is given by mail,  neither  the
failure to mail such  notice,  nor any  defect in any  notice so mailed,  to any
particular  Holder shall affect the  sufficiency  of such notice with respect to
other  Holders.  Any notice mailed to a Holder in the manner  herein  prescribed
shall be  conclusively  deemed to have been received by such Holder,  whether or
not such Holder actually receives such notice. Where this Indenture provides for
notice  in any  manner,  such  notice  may be waived in  writing  by the  Person
entitled to receive  such  notice,  either  before or after the event,  and such
waiver  shall be the  equivalent  of such  notice.  Waivers of notice by Holders
shall be filed  with the  Trustee,  but such  filing  shall  not be a  condition
precedent to the validity of any action taken in reliance upon such waiver.

                  In case by reason of the  suspension of or  irregularities  in
regular mail service or by reason of any other cause, it shall be  impracticable
to mail notice of any event to Holders  when such notice is required to be given
pursuant  to any  provision  of this  Indenture,  then any manner of giving such
notice  shall be  deemed to be a  sufficient  giving  of such  notice  for every
purpose hereunder.

                  SECTION 107.      Conflict of Any Provision of Indenture with
                                   Trust Indenture Act.

                  If and to the  extent  that any  provision  of this  Indenture
limits,  qualifies or conflicts  with the duties imposed by Sections 310 to 318,
inclusive,  of the Trust  Indenture  Act, or conflicts  with any  provision  (an
"incorporated provision") required by or deemed to be included in this Indenture
by operation  of such Trust  Indenture  Act  sections,  such  imposed  duties or
incorporated provision shall control.

                  SECTION 108.      Effect of Headings and Table of Contents.

                  The  Article  and  Section  headings  herein  and the Table of
Contents are for convenience only and shall not affect the construction  hereof.
Articles  and  Sections  referred  to herein  shall refer to such  Articles  and
Sections as set forth herein, unless otherwise specified.

                  SECTION 109.      Successors and Assigns.

                  All covenants and  agreements in this Indenture by the Company
and any Subsidiary  Guarantor shall bind its respective  successors and assigns,
whether so expressed or not.

                  SECTION 110.      Separability Clause.

                  In case any provision in this  Indenture or in the  Securities
shall  be  invalid,  illegal  or  unenforceable,   the  validity,  legality  and
enforceability  of the remaining  provisions shall not in any way be affected or
impaired thereby.

<PAGE>

                  SECTION 111.      Benefits of Indenture.

implied,  shall give to any Person,  other than the parties  hereto,  any Paying
Agent,  any  Registrar  and their  successors  hereunder,  and the Holders,  any
benefit or any legal or equitable right, remedy or claim under this Indenture.

Indenture  shall be subject to the  provisions of the Trust  Indenture Act, that

hereof,  Stated Maturity or Maturity,  Change of Control  Purchase Date or Asset
Sale  Purchase  Date  with  respect  to any  Security  or  other  date on  which
principal, premium or interest in respect or the Securities is due, shall not be
a Business Day, then  (notwithstanding  any other provision of this Indenture or
of the  Securities)  payment of principal (or premium,  if any) or interest need
not be made on such date,  but may be made on the next  succeeding  Business Day
with  the  same  force  and  effect  as if made on the  Interest  Payment  Date,
Redemption Date, date established for payment of Defaulted  Interest pursuant to

such day,  Redemption Date, date  established for payment of Defaulted  Interest
pursuant to Section 309 hereof,  Stated Maturity or Maturity,  Change of Control
Purchase Date,  Asset Sale Purchase Date or such other date, as the case may be,

                  The Company and each of the Subsidiary  Guarantors agrees that
any legal suit, action or proceeding  brought by any party to enforce any rights
under or with respect to this  Indenture or the  Securities may be instituted in
any state or  federal  court in The City of New York and  waives to the  fullest
extent  permitted by law any objection which it may now or hereafter have to the
laying of venue of any such suit,  action or proceeding and irrevocably  submits
to the non-exclusive  jurisdiction of any such court in any such suit, action or
proceeding. The Company and each of the Subsidiary Guarantors hereby irrevocably
designates  and  appoints  CT  Corporation  System  as the  Company's  and  such
Subsidiary  Guarantor's  authorized  agent to receive  and forward on its behalf
service of any and all process  which may be served in any such suit,  action or
proceeding  in any such  court  and  agrees  that  service  of  process  upon CT
Corporation System at its office at 1633 Broadway, New York, New York 10019, (or
such other  address in the State of New York as the  Company  may  designate  by
written notice to the Trustee) and written notice of such service to the Company
and any Subsidiary Guarantor marked or delivered to CT Corporation System at its
address set forth herein shall be deemed in every respect  effective  service of
process upon the Company and such Subsidiary  Guarantor in any such suit, action
or proceeding and shall be taken and held to be valid personal  service upon the
Company.  Nothing in this Section 114 shall affect the right of any party hereto
to serve process in any manner  permitted by law or limit the right of any party
hereto to bring proceedings  against the Company or any Subsidiary  Guarantor in
the courts of any  jurisdiction  or  jurisdictions.  The Company and each of the
Subsidiary  Guarantors further agrees to take any and all action,  including the
execution  and filing of any and all such  documents and  instruments  as may be
necessary to continue such designation and appointment of CT Corporation  System
in full  force and  effect so long as this  Indenture  or any of the  Securities
shall be outstanding. To the extent that the Company or any Subsidiary Guarantor
has or hereafter may acquire any immunity from jurisdiction of any court or from
any legal  process  (whether  through  service  of notice,  attachment  prior to
judgment, attachment in aid of execution, executor or otherwise) with respect to
itself  or its  property,  the  Company  and such  Subsidiary  Guarantor  hereby
irrevocably  waive  such  immunity  in  respect  of its  obligations  under this
Indenture, the Securities and the applicable Subsidiary Guarantee, to the extent

required or permitted by this Indenture,  and may have such letters,  numbers or
other marks of identification and such legends or endorsements placed thereon as
may be required to comply with the rules of any  securities  exchange or as may,
consistently  herewith, be determined by the officers executing such Securities,
as evidenced by their  execution of the  Securities.  Any portion of the text of
any  Security  may be set  forth on the  reverse  thereof,  with an  appropriate
reference thereto on the face of the Security.

                  The definitive  Securities  shall be printed,  lithographed or
engraved on steel-engraved  borders or may be produced in any other manner,  all
as  determined  by the officers of the Company  executing  such  Securities,  as
evidenced by their execution of such Securities.

                  The  terms  and  provisions  contained  in  the  form  of  the
Securities  annexed  hereto  as  Exhibit  A shall  constitute,  and  are  hereby
expressly made, a part of this Indenture. To the extent applicable,  the Company
and the Trustee,  by their execution and delivery of this  Indenture,  expressly
agree to such terms and provisions and to be bound thereby.

                  Securities  shall  be  issued  initially  in the  form  of one
permanent global Note in registered form  substantially in the form set forth in
Exhibit A (the "Global Security"),  registered in the name of the nominee of the
Depositary,  deposited with the Trustee,  as custodian for the Depositary,  duly
executed  by the  Company  and  authenticated  by  the  Trustee  as  hereinafter
provided. The aggregate principal amount of the Global Security may from time to
time be  increased  or  decreased  by  adjustments  made on the  records  of the
Trustee,  as  custodian  for  the  Depositary  or its  nominee,  as  hereinafter
provided.

                  Securities   offered  and  sold  in  the  form  of   permanent
certificated  Securities in registered form shall be in  substantially  the form
set forth in Exhibit A (the "Physical  Securities"),  except that the legends of
such  Securities  shall  not  contain  language  which  pertains  to the  Global
Security.

                  SECTION 202.      Restrictive Legends.

                  Unless  and  until  an  Initial  Security  is  sold  under  an
effective Shelf  Registration  Statement or an Initial Security is exchanged for
an Exchange Security in connection with an effective Exchange Offer Registration
Statement, in each case pursuant to the Note Registration Rights Agreement,  the
Global  Security and any Physical  Securities  shall bear the legend,  set forth
below on the face thereof (the "Private Placement Legend"):

         "THE  SECURITY (OR ITS  PREDECESSOR)  EVIDENCED  HEREBY WAS  ORIGINALLY

         ACT"), AND THE SECURITY  EVIDENCED  HEREBY MAY NOT BE OFFERED,  SOLD OR
         OTHERWISE  TRANSFERRED  IN  THE  ABSENCE  OF  SUCH  REGISTRATION  OR AN
         APPLICABLE  EXEMPTION   THEREFROM.   EACH  PURCHASER  OF  THE  SECURITY
         EVIDENCED HEREBY (1) BY ITS ACQUISITION  HEREOF REPRESENTS THAT IT IS A
         "QUALIFIED  INSTITUTIONAL  BUYER"  (AS  DEFINED  IN RULE 144A UNDER THE

         DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING
         THE  REQUIREMENTS  OF  RULE  144A,  (b) IN A  TRANSACTION  MEETING  THE
         REQUIREMENTS  OF  RULE  144A  UNDER  THE  SECURITIES  ACT,  OR  (c)  IN
         ACCORDANCE  WITH  ANOTHER  AVAILABLE  EXEMPTION  FROM THE  REGISTRATION
         REQUIREMENTS  OF THE  SECURITIES  ACT (AND  BASED  UPON AN  OPINION  OF
         COUNSEL  IF THE  COMPANY  SO  REQUESTS),  (ii) TO THE  COMPANY OR (iii)
         PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT AND, IN EACH CASE, IN
         ACCORDANCE  WITH ANY  APPLICABLE  SECURITIES  LAWS OF ANY  STATE OF THE
         UNITED STATES OR ANY OTHER  APPLICABLE  JURISDICTION AND (Y) THE HOLDER
         WILL, AND WILL REQUIRE EACH SUBSEQUENT  HOLDER TO, NOTIFY ANY PURCHASER

                  Each  Global  Security,  whether or not an  Initial  Security,
shall also bear the following legend on the face thereof:

                                 THE SECURITIES

                  SECTION 301.      Title and Terms.

                  The Initial  Securities  shall be known and  designated as the
"11 1/2% Senior Notes due 2006" and the Exchange  Securities  shall be known and
designated as the "11 1/2% Senior Notes due 2006, Series B." The Stated Maturity
of the Securities shall be January 15, 2006, and they shall bear interest at the
rate of 11 1/2% per annum (subject to adjustments as set forth below) from March
2, 1999,  or from the most recent  Interest  Payment Date to which  interest has
been paid or duly provided for,  payable  semiannually on January 15 and July 15
in each year,  commencing July 15, 1999, until the principal  thereof is paid or
duly provided for, to the Person in whose name the Security (or any  predecessor
Security) is registered at the close of business on the January 1 or July 1 next
preceding such Interest Payment Date.

                  In the event that the Adjusted  Stockholders' Equity is not at
least  $40,000,000 on each of December 31, 1999,  June 30, 2000 and December 31,
2000,  the rate at which the  Securities  bear interest shall be adjusted on the
date  following  each such  date to 13%,  14% and 15% per  annum,  respectively,
except as such rate may be  adjusted  pursuant to the Note  Registration  Rights
Agreement and Warrant Registration Rights Agreement in connection with a default
of the Company's obligations  thereunder to file, cause to be declared effective
and keep effective registration statements filed with the Commission.

                  Pursuant the terms of the Note  Registration  Rights Agreement
attached  hereto as  Exhibit B and the  Warrant  Registration  Rights  Agreement
attached  hereto as Exhibit C, the rate at which the Securities bear interest is
subject to an additional increase based upon the terms and conditions  specified
in the form of Security attached hereto as Exhibit A.

                  The  principal of (and premium,  if any),  and interest on the
Securities  shall be  payable,  and the  Securities  shall be  exchangeable  and
transferable,  at the  office or agency of the  Company  in The City of New York
maintained  for such  purposes,  (which  initially  shall be the  office  of the
Trustee located at One State Street,  New York, New York 10004 or, at the option
of the  Company,  interest  may be paid by check  mailed to the  address  of the
Person entitled  thereto as such address shall appear on the Security  Register;
provided  that all  payments  with respect to each Global  Security,  as well as
Physical  Securities the Holders of which have given wire transfer  instructions
to the  Trustee  (or other  Paying  Agent) by the  Regular  Record Date for such
payment,  shall be required to be made by wire transfer of immediately available
funds to the accounts specified by the Holders thereof.

                  Initial   Securities   that  remain   outstanding   after  the
consummation of the Exchange Offer and Exchange  Securities issued in connection
with the Exchange  Offer will be treated as a single class of  securities  under
this Indenture.

                  The  Securities  shall be  redeemable  as  provided in Article
Eleven.

                  SECTION 302.      Denominations.

                  The  Securities  shall be issuable  only in  registered  form,
without coupons,  and only in  denominations  of $10,000 and integral  multiples
thereof.

                  SECTION 303.   Execution, Authentication, Delivery and Dating.

                  The  aggregate  principal  amount of  Securities  which may be
authenticated and delivered under this Indenture is $100,000,000. The Securities
shall be  executed  on behalf of the Company by its  Chairman,  Chief  Executive
Officer and President,  its Chief Financial  Officer or any Vice President.  The
signature of any of these  officers on the Securities may be manual or facsimile
signatures  of the  present or any future  such  authorized  officer  and may be
imprinted or otherwise reproduced on the Securities.

                  Securities  bearing  the  manual or  facsimile  signatures  of
individuals  who were at any time the proper  officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

<PAGE>

                  On the date hereof,  after the  execution and delivery of this
Indenture,  the  Company  shall  deliver  Initial  Securities  in the  aggregate
principal  amount of  $100,000,000  executed  by the  Company to the Trustee for
authentication,  together  with a  Company  Order  for  the  authentication  and
delivery of such Initial  Securities  directing the Trustee to authenticate  the
Initial Securities and certifying that all conditions  precedent to the issuance
of Securities contained herein have been fully complied with, and the Trustee in
accordance with such Company Order shall  authenticate  and deliver such Initial
Securities.  On Company Order, the Trustee shall authenticate for original issue
Exchange Securities in an aggregate principal amount not to exceed $100,000,000;
provided  that such  Exchange  Securities  shall be issuable only upon the valid
surrender for cancellation of Initial  Securities of a like aggregate  principal
amount in accordance  with an Exchange Offer  pursuant to the Note  Registration
Rights  Agreement  and  a  Company  Order  delivered  to  the  Trustee  for  the
authentication and delivery of such Exchange  Securities and certifying that all
conditions  precedent to the issuance of such Securities have been complied with
(including  the  effectiveness  of the  Exchange  Offer  Registration  Statement
related  thereto).  In each case,  the  Trustee  shall be entitled to receive an
Officers'  Certificate  and an Opinion  of Counsel of the  Company to the effect
that  the  form  of  the   securities   being   delivered  to  the  Trustee  for
authentication comply with the terms and provisions of this Indenture,  that all
terms and  provisions of this Indenture have been complied with for the issuance
of Exchange  Securities  or such other  matters as the  Trustee  may  reasonably
request in connection with such authentication of Securities. Each Company Order
shall specify the amount of Securities to be authenticated and the date on which
the original issue of Securities is to be authenticated.

                  Each Security shall be dated the date of its authentication.

                  No  Security  shall be  entitled  to any  benefit  under  this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication  substantially in the form provided for
in Exhibit A hereto  duly  executed  by the  Trustee by manual  signature  of an
authorized  officer,  and such certificate upon any Security shall be conclusive
evidence, and the only evidence,  that such Security has been duly authenticated
and delivered hereunder and is entitled to the benefits of this Indenture.

                  In case the  Company,  pursuant  to  Article  Eight,  shall be
consolidated or merged with or into any other Person or shall convey,  transfer,
lease or otherwise  dispose of its  properties  and assets  substantially  as an
entirety  to  any  Person,   and  the  successor   Person  resulting  from  such
consolidation,  or surviving  such merger,  or into which the Company shall have
been merged,  or the Person which shall have  received a  conveyance,  transfer,
lease or other  disposition  as  aforesaid,  shall have  executed  an  indenture
supplemental  hereto with the  Trustee  pursuant  to Article  Eight,  any of the
Securities  authenticated  or  delivered  prior to such  consolidation,  merger,
conveyance,  transfer, lease or other disposition may, from time to time, at the
request of the successor Person,  be exchanged for other Securities  executed in
the name of the successor  Person with such changes in  phraseology  and form as
may be  appropriate  as determined by the Company or the successor  Person,  but
otherwise  in  substance of like tenor as the  Securities  surrendered  for such
exchange and of like principal amount; and the Trustee,  upon Company Request or
the successor Person,  shall authenticate and deliver Securities as specified in
such request for the purpose of such exchange.  If Securities  shall at any time
be authenticated and delivered in any new name of a successor Person pursuant to
this Section in exchange or substitution for or upon registration of transfer of
any Securities,  such successor Person, at the option of the Holders but without
expense to them or the Trustee, shall provide for the exchange of all Securities
at the time Outstanding for Securities  authenticated  and delivered in such new
name.

                  The  Trustee may appoint an  authenticating  agent  reasonably
acceptable to the Company to  authenticate  the Securities  (an  "Authenticating
Agent").  Unless  limited by the terms of such  appointment,  an  Authenticating
Agent may authenticate Securities whenever the Trustee may do so. Each reference
in this Indenture to  authentication  by the Trustee includes  authentication by
such agent. An Authenticating Agent has the same rights as any Registrar, Paying
Agent or agent for service of notices and demands.

                  SECTION 304.      Temporary Securities.

                  Pending the preparation of definitive Securities,  the Company
may execute,  and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed,  typewritten, mimeographed
or otherwise  produced,  in any authorized  denomination,  substantially  of the
tenor of the  definitive  Securities  in lieu of which  they are issued and with
such appropriate  insertions,  omissions,  substitutions and other variations as
the Company's officers executing such Securities may determine,  as conclusively
evidenced by their execution of such Securities.

                  If temporary  Securities  are issued,  the Company shall cause
definitive  Securities  to be prepared  without  unreasonable  delay.  After the
preparation  of  definitive  Securities,   the  temporary  Securities  shall  be
exchangeable   for  definitive   Securities  upon  surrender  of  the  temporary
Securities  at the office or agency of the Company  designated  for such purpose
pursuant to Section 1002 hereof,  without  charge to the Holder.  Upon surrender
for  cancellation  of any one or more  temporary  Securities,  the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
like  principal  amount of definitive  Securities  of authorized  denominations.
Until so exchanged,  the temporary  Securities shall in all respects be entitled
to the same benefits under this Indenture as definitive Securities.

                  SECTION 305.      Registration, Registration 
                                   of Transfer and Exchange.

                  The  Company  shall  cause to be kept at the  Corporate  Trust
Office of the Trustee a register (the register  maintained in such office and in
any other  office or agency  designated  pursuant to Section  1002 hereof  being
herein sometimes  referred to as the "Security  Register") in which,  subject to
such reasonable  regulations as it may prescribe,  the Company shall provide for
the  registration  of Securities  and of transfers of  Securities.  The Security
Register  shall be in written form or any other form capable of being  converted
into  written  form within a  reasonable  time.  At all  reasonable  times,  the
Security  Register  shall be open to inspection  by the Trustee.  The Trustee is
hereby  initially  appointed  as  "Registrar"  for the  purpose  of  registering
Securities and transfers of Securities as herein provided.

                  Upon surrender for registration of transfer of any Security at
the office or agency of the Company designated  pursuant to Section 1002 hereof,
the Company shall execute,  and the Trustee shall  authenticate and deliver,  in
the name of the designated transferee or transferees, one or more new Securities
of any authorized  denomination or denominations  of a like aggregate  principal
amount.

                  At the option of the Holder,  Securities  may be exchanged for
other  Securities  of  any  authorized  denomination  and  of a  like  aggregate
principal  amount,  upon  surrender  of the  Securities  to be exchanged at such
office or agency.  Whenever  any  Securities  are so  surrendered  for  exchange
(including  an exchange of Initial  Securities  for  Exchange  Securities),  the
Company shall  execute,  and the Trustee  shall  authenticate  and deliver,  the
Securities which the Holder making the exchange is entitled to receive; provided
that no exchange of Initial Securities for Exchange Securities shall occur until
an Exchange Offer  Registration  Statement shall have been declared effective by
the Commission,  the Trustee shall have received an Officers' Certificate and an
Opinion of Counsel confirming that the Exchange Offer Registration Statement has
been declared effective by the Commission and an Opinion of Counsel stating that
the  Exchange  Securities  are  entitled  to  the  benefits  of  this  Indenture
(including the Subsidiary Guarantees  hereunder),  and the Initial Securities to
be exchanged for the Exchange Securities shall be canceled by the Trustee.

                  All  Securities  issued upon any  registration  of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same  indebtedness,  and entitled to the same benefits under this Indenture,
as the Securities surrendered upon such registration of transfer or exchange.

                  Every Security  presented or surrendered  for  registration of
transfer or for exchange  shall (if so required by the Company or the Registrar)
be duly endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory  to the  Company  and the  Registrar,  duly  executed by the Holder
thereof or his attorney duly authorized in writing.

                  No  service  charge  shall  be made  for any  registration  of
transfer  or  exchange  or  redemption  of  Securities,  but the  Company or the
Registrar  may  require  payment of a sum  sufficient  to cover any tax or other
governmental  charge that may be imposed in connection with any  registration of
transfer or exchange of Securities,  other than  exchanges  pursuant to Sections
304, 906, 1012, 1013 or 1108 hereof not involving any transfer.

                  Neither  the Company  nor the  Registrar  shall be required to
issue,  register  the  transfer  of or  exchange  any  Security  during a period
beginning at the opening of business 15 days before the  selection of Securities
to be redeemed  under Section 1104 hereof and ending at the close of business on
the day of such mailing of the relevant notice of redemption.

                  Notwithstanding anything to the contrary contained herein, the
Trustee shall have no duty  whatsoever and no liability  whatsoever with respect
to compliance with federal or state securities laws, rules or regulations.

                  SECTION 306.      Book-Entry Provisions for Global Securities.

                  (a)......The Global Security initially shall (i) be registered
in the  name  of the  Depositary  or the  nominee  of the  Depositary,  (ii)  be
deposited  with,  or on  behalf  of,  the  Depositary  or with the  Trustee,  as
custodian  for such  Depositary,  and (iii) bear legends as set forth in Section
202 hereof.  Except as set forth  below,  owners of  beneficial  interests  in a
Global  Security will not be entitled to receive  physical  delivery of Physical
Securities in registered form without interest coupons.

                  Members  of,  or  participants  in,  the  Depositary   ("Agent
Members")  shall have no rights under this  Indenture with respect to any Global
Security  held  on  their  behalf  by  the  Depositary,  or the  Trustee  as its
custodian,  or under the Global Security, and the Depositary shall be treated by
the  Company,  the  Trustee  and any agent of the  Company or the Trustee as the
absolute   owner  of  such  Global   Security  for  all   purposes   whatsoever.
Notwithstanding  the foregoing,  nothing  herein shall prevent the Company,  the
Trustee or any agent of the  Company or the Trustee  from  giving  effect to any
written certification,  proxy or other authorization furnished by the Depositary
(or shall impair, as between the Depositary and its Agent Members, the operation
of customary  practices  governing the exercise of the rights of a holder of any
Security),  and the  Company,  the  Trustee  or any agent of the  Company or the
Trustee shall be entitled to rely thereon in accordance with such certification,
proxy or other authorization in accordance with its terms.

<PAGE>

                  (b)......Transfers  of a Global  Security  shall be limited to
transfers of such Global Security in whole,  but not in part, to the Depositary,
its successors or their respective nominees. Interests of beneficial owners in a
Global  Security may be transferred in accordance  with the rules and procedures
of the  Depositary  and the  provisions  of Section  307  hereof.  In  addition,
Physical  Securities  shall be transferred to all beneficial  owners in exchange
for  their  beneficial  interests  in  the  Global  Security  respectively,   in
accordance with instructions from the Depositary, if (i) the Depositary notifies
the  Company  and the  Trustee  that it is  unwilling  or unable to  continue as
Depositary  for the  Global  Security  or has  ceased  to be a  clearing  agency
registered under the Exchange Act and, in either case, a successor depositary is
not appointed by the Company within 90 days of such notice, (ii) the Company, in
its sole discretion, notifies the Trustee in writing that it elects to cause the
issuance of the Physical  Securities,  or (iii) an Event of Default has occurred
and is  continuing  and is known to the Trustee and the Registrar has received a
request from the Depositary.

                  (c)......In  connection  with any transfer of a portion of the
beneficial  interests  in a Global  Security to  beneficial  owners  pursuant to
subsection  (b) of this Section,  the  Registrar  shall reflect on its books and
records the date and a decrease in the principal  amount of the Global  Security
in an amount equal to the principal  amount of the  beneficial  interest in such
Global  Security to be  transferred,  and the  Company  shall  execute,  and the
Trustee shall authenticate and deliver,  one or more Physical Securities of like
tenor and amount.

                  (d)......In  connection with the transfer of the entire Global
Security to beneficial  owners  pursuant to subsection (b) of this Section,  the
Global   Security  shall  be  deemed  to  be  surrendered  to  the  Trustee  for
cancellation,  and the Company shall execute, and the Trustee shall authenticate
and deliver,  to each beneficial  owner identified by the Depositary in exchange
for its beneficial  interest in the Global Security identified by the Depositary
an equal  aggregate  principal  amount  of  Physical  Securities  of  authorized
denominations.

                  (e)......Any  Physical  Security  delivered in exchange for an
interest in the Global  Security  pursuant  to  subsection  (b) of this  Section
shall, except as otherwise provided by paragraph (c) of Section 307 hereof, bear
the applicable legend regarding transfer restrictions applicable to the Physical
Security set forth in Section 202 hereof.

                  (f)......The  registered Holder of a Global Security may grant
proxies and otherwise authorize any Person,  including Agent Members and Persons
that may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Securities.

                  SECTION 307.      Special Transfer Provisions.

                  The  Trustee  is  entitled  to  rely  upon  the   certificates
delivered pursuant to this Section 307 and is irrevocably  authorized to produce
such   certificates   or  copies  thereof  to  any   interested   party  in  any
administrative  or legal  proceeding  or official  inquiry  with  respect to the
matters covered thereby.

                  Unless and until the Trustee has received a certification from
the  Company  that (i) an  Initial  Security  is sold under an  effective  Shelf
Registration  Statement or (ii) an Initial Security is exchanged for an Exchange
Security in connection with an effective  Registration  Statement,  in each case
pursuant to the Note  Registration  Rights Agreement,  the following  provisions
shall apply:

                  (a)......Transfers  to QIBs.  The following  provisions  shall
apply with respect to the  registration  of any proposed  transfer of a Physical
Security or an interest in the Global Security to a QIB:

                  (i) If the Security to be transferred consists of (x) Physical
         Securities,  the Registrar shall register the transfer if such transfer
         is being made by a proposed transferor who has checked the box provided
         for on the form of Initial Security  stating,  or has otherwise advised
         the Company and the  Registrar in writing,  that the sale has been made
         in compliance  with the provisions of Rule 144A to a transferee who has
         signed the  certification  provided for on the form of Initial Security
         stating,  or has  otherwise  advised the Company and the  Registrar  in
         writing, that it is purchasing the Initial Security for its own account
         or an  account  with  respect  to which it  exercises  sole  investment
         discretion and that it, or the Person on whose behalf it is acting with
         respect to any such account,  is a QIB within the meaning of Rule 144A,
         and is aware that the sale to it is being made in reliance on Rule 144A
         and acknowledges  that it has received such  information  regarding the
         Company as it has requested pursuant to Rule 144A or has determined not
         to request such information and that it is aware that the transferor is
         relying  upon its  foregoing  representations  in  order  to claim  the
         exemption from registration provided by Rule 144A or (y) an interest in
         the Global Security, the transfer of such interest may be effected only
         through the book-entry system maintained by the Depositary.

                  (ii) If the proposed  transferee is an Agent  Member,  and the
         Initial  Security to be  transferred  consists of Physical  Securities,
         upon receipt by the  Registrar of the  documents  referred to in clause
         (i) and  instructions  given by the  Depositary in accordance  with the
         Depositary's  and the Registrar's  procedures  therefor,  the Registrar
         shall  reflect on its books and records the date and an increase in the
         principal  amount of the  Global  Security  in an  amount  equal to the
         principal amount of the Physical Securities to be transferred,  and the
         Trustee shall cancel the Physical Security so transferred.

<PAGE>

                  (b)......Other  Transfers of Physical  Securities or Interests
in the Global Security. The following provisions shall apply with respect to any
other transfer of interests in the Global Security or Physical Securities:

                  (i) prior to the removal of the Private  Placement Legend from
         the Global  Security  or a Physical  Security  pursuant  to Section 202
         hereof,  the Registrar  shall refuse to register  such transfer  unless
         such transfer complies with Section 306(b); and

                  (ii) after such  removal,  the  Registrar  shall  register the
         transfer  of  any  such  Security  without   requiring  any  additional
         certification.

                  (c)......Private Placement Legend. Upon the transfer, exchange
or  replacement  of Securities  not bearing the Private  Placement  Legend,  the
Registrar  shall  deliver  Securities  that do not  bear the  Private  Placement
Legend.  Upon the transfer,  exchange or replacement  of Securities  bearing the
Private Placement Legend,  the Registrar shall deliver only Securities that bear
the Private  Placement  Legend unless either (i) the Company directs the Trustee
pursuant to a Company  Order to remove such legend or (ii) there is delivered to
the Registrar an Opinion of Counsel  reasonably  satisfactory  to the Company to
the effect that neither such legend nor the related restrictions on transfer are
required in order to maintain  compliance  with the provisions of the Securities
Act.

                  (d)......General.  By its  acceptance of any Security  bearing
the Private  Placement Legend,  each Holder of such a Security  acknowledges the
restrictions on transfer of such Security set forth in this Indenture and in the
Private  Placement Legend and agrees that it will transfer such Security only as
provided in this Indenture.

                  The  Registrar  shall  retain as required by law copies of all
letters,  notices and other written communications  received pursuant to Section
306 hereof or this Section 307. The Company  shall have the right to inspect and
make copies of all such letters,  notices or other written communications at any
reasonable time upon the giving of reasonable written notice to the Registrar.

                  SECTION 308.      Mutilated, Destroyed, Lost and 
Stolen Securities.

                  If (i) any mutilated Security is surrendered to the Trustee or
the  Registrar,  or (ii) the Company and the Trustee  receive  evidence to their
satisfaction  of the  destruction,  loss or theft of any Security,  and there is
delivered  to the Company and the Trustee  such  security or indemnity as may be
required by them to save each of them  harmless,  then, in the absence of notice
to the Company or the Trustee  that such  Security  has been  acquired by a bona
fide  purchaser,  the Company  shall  execute and upon Company Order the Trustee
shall  authenticate and deliver,  in exchange for any such mutilated Security or
in lieu of any such destroyed,  lost or stolen Security,  a new Security of like
tenor and principal amount, bearing a number not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable,  the Company in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section,  the
Company may require  the payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Security  issued pursuant to this Section in lieu of
any mutilated,  destroyed,  lost or stolen Security shall constitute an original
additional contractual obligation of the Company,  whether or not the mutilated,
destroyed,  lost or stolen Security shall be at any time  enforceable by anyone,
and  shall  be  entitled  to  all  benefits  of  this   Indenture   equally  and
proportionately with any and all other Securities duly issued hereunder.

                  The  provisions  of  this  Section  are  exclusive  and  shall
preclude (to the extent  lawful) all other  rights and remedies  with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                  SECTION 309.   Payment of Interest; Interest Rights Preserved.

                  Interest on any Security  which is payable,  and is punctually
paid or duly  provided  for, on any  Interest  Payment Date shall be paid to the
Person in whose name such Security is registered at the close of business on the
Regular  Record Date for such interest at the office or agency of the Company in
The City of New York maintained for such purposes (which  initially shall be the
office of the Trustee  located at One State  Street,  New York,  New York 10004)
pursuant to Section 1002 hereof) or, at the option of the Company,  interest may
be paid by check mailed to the address of the Person entitled  thereto  pursuant
to 310 hereof as such address  appears in the Security  Register;  provided that
all payments  with respect to a Global  Security  and  Physical  Securities  the
Holders of which have given wire transfer  instructions to the Trustee (or other
Paying  Agent) by the  Regular  Record Date shall be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof.

<PAGE>

                  Any interest on the Securities shall be considered  punctually
paid or duly provided for if the Paying Agent holds immediately  available funds
no later than 11:00 A.M. New York City time on the applicable  Interest  Payment
Date. Any interest on any Security which is payable,  but is not punctually paid
or duly provided for, on any Interest  Payment Date shall  forthwith cease to be
payable to the Holder on the  Regular  Record Date by virtue of having been such
Holder,  and such defaulted interest and (to the extent lawful) interest on such
defaulted  interest at the rate borne by the Securities (such defaulted interest
and interest thereon herein  collectively  called  "Defaulted  Interest") may be
paid by the Company,  at its election in each case, as provided in clause (a) or
(b) below:

                  (a) The  Company  may elect to make  payment of any  Defaulted
         Interest  to the  Persons  in whose  names  the  Securities  (or  their
         respective  predecessor  securities)  are  registered  at the  close of
         business on a Special  Record  Date for the  payment of such  Defaulted
         Interest,  which shall be fixed in the  following  manner.  The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed  to be paid  on each  Security  and the  date of the  proposed
         payment,  and at the  same  time the  Company  shall  deposit  with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted  Interest or shall make  arrangements
         satisfactory  to the Trustee for such deposit  prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons  entitled to such Defaulted  Interest as in this
         clause provided.  Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days and not  less  than 10 days  prior to the date of the  proposed
         payment  and not less than 10 days after the  receipt by the Trustee of
         the notice of the proposed  payment.  The Trustee shall promptly notify
         the Company of such  Special  Record  Date,  and in the name and at the
         expense of the Company,  shall cause notice of the proposed  payment of
         such  Defaulted  Interest  and the Special  Record Date  therefor to be
         given in the manner  provided for in Section 106 hereof,  not less than
         10 days  prior to such  Special  Record  Date.  Notice of the  proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having  been so given,  such  Defaulted  Interest  shall be paid to the
         Persons in whose names the Securities (or their respective  predecessor
         Securities)  are  registered  at the close of business on such  Special
         Record Date and shall no longer be payable  pursuant  to the  following
         clause (b).

                  (b) The Company may make payment of any Defaulted  Interest in
         any other lawful manner not  inconsistent  with the requirements of any
         securities  exchange on which the  Securities  may be listed,  and upon
         such notice as may be required by such exchange, if, after notice given
         by the Company to the Trustee of the proposed  payment pursuant to this
         clause,  such  manner of  payment  shall be deemed  practicable  by the
         Trustee.

                  Subject to the  foregoing  provisions  of this  Section,  each
Security  delivered under this Indenture upon  registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                  If  the  Company  shall  be  required  to pay  any  additional
interest  pursuant  to Section  301 hereof or  pursuant to the terms of the Note
Registration Rights Agreement or Warrant Registration Rights Agreement, it shall
deliver an Officers'  Certificate to the Trustee  setting forth the new interest
rate and the period for which such rate is applicable.

                  SECTION 310.      Persons Deemed Owners.

                  Prior to the due presentment of a Security for registration of
transfer,  the Company,  the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such  Security is  registered in the Security
Register as the owner of such  Security for the purpose of receiving  payment of
principal of (and premium,  if any) and (subject to Sections 305 and 309 hereof)
interest on such Security and for all other purposes whatsoever,  whether or not
such Security be overdue,  and none of the Company,  any Subsidiary Guarantor or
the Trustee or any agent of the Company, any Subsidiary Guarantor or the Trustee
shall be affected by notice to the contrary.

                  SECTION 311.      Cancellation.

                  All   Securities   surrendered   for   payment,    redemption,
registration  of transfer or exchange  shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company may at any time  deliver to the  Trustee  for  cancellation  any
Securities  previously  authenticated and delivered  hereunder which the Company
may have acquired in any manner  whatsoever,  and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously  authenticated  hereunder  which the Company has not issued and sold,
and all Securities so delivered shall be promptly  cancelled by the Trustee.  If
the Company shall so acquire any of the Securities,  however,  such  acquisition
shall  not  operate  as  a  redemption  or  satisfaction  of  the   indebtedness
represented by such Securities  unless and until the same are surrendered to the
Trustee for cancellation.  No Securities shall be authenticated in lieu of or in
exchange  for any  Securities  canceled as provided in this  Section,  except as
expressly  permitted  by this  Indenture.  All canceled  Securities  held by the
Trustee  shall be disposed of by the Trustee in  accordance  with its  customary
procedures and  certification of their disposal  delivered to the Company unless
by Company Order the Company shall direct that cancelled  Securities be returned
to it.

<PAGE>

                  SECTION 312.      CUSIP Numbers.

                  The Company in issuing the Securities may use "CUSIP"  numbers
(if then  generally  in use) and,  if so,  the  Trustee  shall use such  "CUSIP"
numbers in notices of redemption as a convenience to Holders;  provided that any
such notice may state that no  representation  is made as to the  correctness of
such numbers  either as printed on the  Securities or as contained in any notice
of a redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                  SECTION 313.      Computation of Interest.

                  Interest on the Securities shall be computed on the basis of a
360-day year comprised of twelve 30-day months.

acknowledging satisfaction and discharge of this Indenture when

                  (a)      either

                           (i) all the Securities theretofore  authenticated and
                  delivered  (other than  mutilated,  destroyed,  lost or stolen

                  Section  308  and   Securities   that  have  been  subject  to
                  defeasance under Article  Thirteen) have been delivered to the

                           (ii)     all Securities not theretofore  delivered t
 the Trustee for cancellation  have become due and payable, whether

                                    (A)     at Stated Maturity, or

                                    (B) the Company has irrevocably notified the
                           Trustee to call such Securities for redemption  under
                           arrangements  for the giving of notice of  redemption
                           by the Trustee in the name,  and at the  expense,  of
                           the Company,

and the Company or any Subsidiary Guarantor,  as the case may be, in the case of

Securities  that have  become  due and  payable)  or to the Stated  Maturity  or
Redemption Date, as the case may be; and

                  (b)      the Company or any  Subsidiary  Guarantor,  as the 
case may be, has paid or caused to be paid all sums payable hereunder by the

obligations  of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of
this Section 401, the  obligations of the Trustee under Section 402 and the last

determine,  to the Persons entitled thereto,  of the principal (and premium,  if
any) and  interest  for whose  payment  such money has been  deposited  with the
Trustee;  but such money need not be  segregated  from other funds except to the

         Restricted  Subsidiaries  (or the payment of which is Guaranteed by the
         Company  or  any  of  its   Restricted   Subsidiaries)   whether   such
         Indebtedness  or Guarantee now exists,  or is created after the date of
         this Indenture, if that default:

                           (i) is  caused by a failure  to pay  principal  of or
                  premium, if any, or interest on such Indebtedness prior to the
                  expiration of the grace period  provided in such  Indebtedness
                  on the date of such default (a "Payment Default"); or

         stayed  for a period of 10 days after  notice  (the  "judgment  default

         or invalid or shall cease for any reason to be in full force and effect
         or any  Subsidiary  Guarantor,  or any  Person  acting on behalf of any

                  However, a default under clause (d), (e) or (f) above will not
         constitute  an Event of Default until the Trustee or the Holders of 25%
         in principal amount of the Outstanding Securities notify the Company of
         the Default and the Company does not cure such Default  within the time
         specified after receipt of such notice.

                  SECTION 502.      Acceleration of Maturity; Rescission and 
         Annulment.

                  (a)......If  an Event of Default  (other than as  specified in
clauses (h) and (i) of Section 501 hereof) occurs and is continuing, the Trustee
by notice to the Company  may,  and the Trustee at the request of the Holders of
not  less  than  25%  in  aggregate  principal  amount  of the  Securities  then
outstanding shall, declare the principal of and accrued and unpaid interest,  if
any, on all of the outstanding Securities immediately due and payable. Upon such
a declaration,  such principal and accrued and unpaid  interest shall become due
and payable  immediately.  If an Event of Default specified in clause (h) or (i)
of  Section  501 hereof  occurs and is  continuing,  then the  principal  of and
accrued and unpaid interest, if any, on all of the outstanding  Securities shall
ipso facto become and be immediately  due and payable without any declaration or
other act on the part of the Trustee or any Holder.

                  In the case of any Event of Default occurring by reason of any
willful  action or  inaction  taken or not taken by or on behalf of the  Company
with the  intention of avoiding  payment of the premium  that the Company  would
have had to pay if the  Company  then  had  elected  to  redeem  the  Securities
pursuant  to Section  1101,  an  equivalent  premium  shall  also  become and be
immediately due and payable to the extent permitted by law upon the acceleration
of the  Securities.  If an Event of  Default  occurs  prior to March 2,  2003 by
reason of any willful action (or inaction)  taken (or not taken) by or on behalf
of the Company with the intention of avoiding the  prohibition  on redemption of
the  Securities  prior to March 2, 2003,  then the premium  payable  pursuant to
Section  1101  shall  also  become  immediately  due and  payable  to the extent
permitted by law upon the acceleration of the Securities.

                  (b)......At any time after a declaration of acceleration under
this Indenture, but before a judgment or decree for payment of the money due has
been obtained by the Trustee,  the Holders of a majority in aggregate  principal
amount of the outstanding  Securities,  by written notice to the Company and the
Trustee,  may (i) rescind  such  declaration  and its  consequences  and (ii) on
behalf of the  Holders of all of the  Securities,  waive any  existing  Event of
Default and its consequences,  except a continuing Event of Default specified in
clause (b) of Section 501, if

                  (A)      the Company has paid or deposited with the Trustee a 
sum sufficient to pay

                           (1)      all Defaulted Interest on all Securities,

                           (2) all unpaid principal of (and premium, if any, on)
                           any  outstanding   Securities  that  has  become  due
                           otherwise than by such  declaration  of  acceleration
                           and  interest  thereon  at  the  rate  borne  by  the
                           Securities,

                           (3)      to the extent that payment of such  interest
                           is lawful,  interest  upon overdue
                           interest and overdue principal at the rate borne by
                           the Securities, and

                           (4)      all sums paid or advanced by the  Trustee  
                           under  this  Indenture  and the reasonable  
                           compensation,  expenses,  disbursements  and  
                           advances of the  Trustee, its agents and counsel; and

                  (B) all  Events of  Default,  other  than the  non-payment  of
                  amounts of principal  of (or premium,  if any, on) or interest
                  on  the  Securities  that  have  become  due  solely  by  such
                  declaration of acceleration, have been cured or waived.

                  No such rescission or waiver shall affect any subsequent 
default or impair any right  consequent thereon.

                  Notwithstanding  the  preceding  paragraph,  in the event of a
declaration of acceleration in respect of the Securities  because of an Event of
Default specified in Section 501(e) shall have occurred and be continuing,  such
declaration of acceleration shall be automatically  annulled if the indebtedness
that is the subject of such Event of Default has been  discharged or the holders
thereof have  rescinded  their  declaration of  acceleration  in respect of such
indebtedness,  and written notice of such  discharge or rescission,  as the case
may be, shall have been given to the Trustee by the Company and countersigned by
the  holders of the  requisite  percentage  of such  indebtedness  or a trustee,
fiduciary or agent for such holders,  within 30 days after such  declaration  of
acceleration  in respect of the  Securities,  and no other  Event of Default has
occurred  during such 30-day  period  which has not been cured or waived  during
such period.

                  SECTION 503.      Collection of Indebtedness and Suits for
Enforcement by Trustee.

                  The Company and each Subsidiary Guarantor covenants that if

                  (a)  default  is made in the  payment  of any  installment  of
         interest on any Security when such interest becomes due and payable and
         such default continues for a period of 30 days, or

                  (b)      default  is made  in the  payment  of the  principal 
of (or  premium,  if any,  on) any Security at the Stated Maturity thereof,

the Company and each Subsidiary Guarantor shall, upon demand of the Trustee, pay
to the  Trustee for the  benefit of the  Holders of such  Securities,  the whole
amount then due and payable on such  Securities for principal  (and premium,  if
any) and interest,  and interest on any overdue principal (and premium,  if any)
and, to the extent that payment of such interest  shall be legally  enforceable,
upon any overdue  installment of interest,  at the rate borne by the Securities,
and, in addition  thereto,  such further  amount as shall be sufficient to cover
the costs and expenses of  collection,  including the  reasonable  compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

                  If the Company or any  Subsidiary  Guarantor,  as the case may
be, fails to pay such amounts  forthwith upon such demand,  the Trustee,  in its
own name as trustee of an express trust, may institute a judicial proceeding for
the collection of the sums so due and unpaid,  may prosecute such  proceeding to
judgment or final decree and may enforce the same against the Company,  any such
Subsidiary  Guarantor or any other obligor upon the  Securities  and collect the
moneys  adjudged  or decreed to be payable in the manner  provided by law out of
the property of the Company,  any such Subsidiary Guarantor or any other obligor
upon the Securities, wherever situated.

                  If an Event of Default occurs and is  continuing,  the Trustee
may in its  discretion  proceed to protect and enforce its rights and the rights
of the Holders by such  appropriate  judicial  proceedings  as the Trustee shall
deem most  effectual  to protect and enforce  any such  rights,  whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

                  SECTION 504.      Trustee May File Proofs of Claim.

                  In  case  of the  pendency  of any  receivership,  insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial  proceeding relative to the Company or any other obligor upon the
Securities  (including any Subsidiary  Guarantor) or the property of the Company
or of such other  obligor  or their  creditors,  the  Trustee  (irrespective  of
whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company for the payment of overdue  principal,
premium,  if any, or interest) shall be entitled and empowered,  by intervention
in such proceeding or otherwise,

                  (a) to file  and  prove  a  claim  for  the  whole  amount  of
         principal  (and  premium,  if any) and  interest  owing  and  unpaid in
         respect of the Securities and to file such other papers or documents as
         may be  necessary  or  advisable  in order to have  the  claims  of the
         Trustee (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee,  its agents and counsel) and
         of the Holders allowed in such judicial proceeding, and

                  (b) to collect and receive any moneys or other  securities  or
         property payable or deliverable upon the conversion or exchange of such
         securities or upon any such claims and to distribute the same;

and any custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator or
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder to make such  payments to the Trustee  and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee  any  amount  due  it  for  the   reasonable   compensation,   expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606 hereof.

                  Nothing  herein  contained  shall be deemed to  authorize  the
Trustee  to  authorize  or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder  thereof,  or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

                  SECTION 505.      Trustee May Enforce Claims Without 
Possession of Securities.

                  All rights of action and claims  under this  Indenture  or the
Securities may be prosecuted and enforced by the Trustee  without the possession
of any of the  Securities or the production  thereof in any proceeding  relating
thereto,  and any such proceeding  instituted by the Trustee shall be brought in
its own name and as trustee of an express  trust,  and any  recovery of judgment
shall, after provision for the payment of the reasonable compensation, expenses,
disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable  benefit  of the  Holders  of the  Securities  in  respect of which such
judgment has been recovered.

                  SECTION 506.      Application of Money Collected.

                  Any money  collected  by the Trustee  pursuant to this Article
shall be  applied  in the  following  order,  at the date or dates  fixed by the
Trustee and, in case of the  distribution  of such money on account of principal
(or premium,  if any) or interest,  upon  presentation of the Securities and the
notation  thereon  of the  payment  if only  partially  paid and upon  surrender
thereof if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee under 
Section 606 hereof;

                  SECOND:  To the payment of the amounts then due and unpaid for
         principal of (and  premium,  if any) and interest on the  Securities in
         respect  of  which or for the  benefit  of which  such  money  has been
         collected,  ratably,  without  preference  or  priority  of  any  kind,
         according  to the  amounts  due  and  payable  on such  Securities  for
         principal (and premium, if any) and interest, respectively; and

                  THIRD:  The balance, if any, to the Company or as a court of 
competent jurisdiction may direct.

                  SECTION 507.      Limitation on Suits.

                  Except to enforce the right to receive  payment of  principal,
premium (if any) or interest  when due, no Holder of any  Securities  shall have
any right to institute any  proceeding,  judicial or otherwise,  with respect to
this  Indenture,  or for the  appointment  of a receiver or trustee,  or for any
other remedy hereunder, unless

                  (a)      such Holder has  previously  given written  notice 
to the Trustee of a continuing  Event of Default;

                  (b) the  Holders of not less than 25% in  principal  amount of
         the  Outstanding  Securities  shall  have made  written  request to the
         Trustee to institute proceedings in respect of such Event of Default in
         its own name as Trustee hereunder;

                  (c)  such  Holder  or  Holders  have  offered  to the  Trustee
         reasonable  indemnity  against  the  costs,  expenses  and  liabilities
         (including  fees and expenses of its agents and counsel) to be incurred
         in compliance with such request;

                  (d)      the  Trustee  for 60 days  after  its  receipt  of 
such  notice,  request  and  offer of indemnity has failed to institute any 
such proceeding; and

                  (e) no direction  inconsistent  with such written  request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority or more in principal amount of the Outstanding Securities;

it being  understood  and intended  that no one or more  Holders  shall have any
right in any manner  whatever by virtue of, or by availing of, any  provision of
this Indenture to affect,  disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain  priority or preference over any other Holders
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided and for the equal and ratable benefit of all the Holders.

                  SECTION 508.      Unconditional Right of Holders to Receive 
Principal, Premium and Interest.

                  Notwithstanding  any other  provision in this  Indenture,  the
Holder  of  any   Security   shall  have  the  right,   which  is  absolute  and
unconditional, to receive payment, as provided herein (including, if applicable,
Article Thirteen) and in such Security of the principal of (and premium, if any)
and (subject to Section 309 hereof)  interest on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption,  on
the  Redemption  Date) and to  institute  suit for the  enforcement  of any such
payment,  and such rights shall not be impaired or affected  without the consent
of such Holder.

                  SECTION 509.      Restoration of Rights and Remedies.

                  If the Trustee or any Holder has  instituted any proceeding to
enforce any right or remedy under this  Indenture and such  proceeding  has been
discontinued or abandoned for any reason,  or has been  determined  adversely to
the  Trustee or to such  Holder,  then and in every  such  case,  subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored  severally and respectively to their former positions  hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                  SECTION 510.      Rights and Remedies Cumulative.

                  Except as otherwise  provided with respect to the  replacement
or  payment  of  mutilated,  destroyed,  lost or stolen  Securities  in the last
paragraph of Section 308 hereof,  no right or remedy  herein  conferred  upon or
reserved to the Trustee or to the  Holders is  intended to be  exclusive  of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be  cumulative  and in  addition  to every other right and remedy  given
hereunder or now or  hereafter  existing at law or in equity or  otherwise.  The
assertion or employment of any right or remedy  hereunder,  or otherwise,  shall
not prevent the  concurrent  assertion or  employment  of any other  appropriate
right or remedy.

<PAGE>

                  SECTION 511.      Delay or Omission Not Waiver.

                  No delay or  omission  of the  Trustee or of any Holder of any
Security  to  exercise  any right or remedy  accruing  upon any Event of Default
shall  impair any such right or remedy or  constitute a waiver of any such Event
of Default or an  acquiescence  therein.  Every  right and remedy  given by this
Article  Five or by law to the Trustee or to the Holders may be  exercised  from
time to time, and as often as may be deemed expedient,  by the Trustee or by the
Holders, as the case may be.

                  SECTION 512.      Control by Holders.

                  The Holders of not less than a majority in principal amount of
the Outstanding  Securities shall have the right to direct the time,  method and
place of conducting any proceeding for any remedy  available to the Trustee,  or
exercising any trust or power conferred on the Trustee, provided that

                  (a)      such direction shall not be in conflict with any rule
of law or with this Indenture,

                  (b)      the  Trustee  may take any  other  action  deemed 
proper  by the  Trustee  which is not  inconsistent with such direction, and

                  (c) the Trustee need not take any action  which might  involve
         it in personal liability or be unjustly  prejudicial to the Holders not
         consenting.

                  Prior to taking any action  hereunder,  the  Trustee  shall be
entitled to  indemnification  satisfactory to it in its sole discretion  against
all losses and expenses caused by taking or not taking such action.

                  SECTION 513.      Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the  Outstanding  Securities  may,  on  behalf  of  the  Holders  of  all of the
Securities, waive any past defaults hereunder, except a default

                  (a) in the payment of the principal of (or premium, if any) or
         interest on any Security, or

                  (b) in respect of a covenant or  provision  hereof which under
         Article  Nine cannot be modified or amended  without the consent of the
         Holder of each Security Outstanding.

                  Upon any such waiver,  such default shall cease to exist,  and
any Event of Default arising  therefrom shall be deemed to have been cured,  for
every  purpose  of  this  Indenture;  but no such  waiver  shall  extend  to any
subsequent or other  default or Event of Default or impair any right  consequent
thereon.

                  SECTION 514.      Waiver of Stay or Extension Laws.

                  The Company and each  Subsidiary  Guarantor  covenant  (to the
extent  that they may  lawfully  do so) that they  shall not at any time  insist
upon,  or  plead,  or in any  manner  whatsoever  claim or take the  benefit  or
advantage  of, any stay or extension  law wherever  enacted,  now or at any time
hereafter in force,  which may affect the covenants or the  performance  of this
Indenture;  and the Company and each  Subsidiary  Guarantor  (to the extent that
they may lawfully do so) hereby  expressly waive all benefit or advantage of any
such law and  covenants  so that they  shall  not  hinder,  delay or impede  the
execution  of any power  herein  granted to the  Trustee,  but shall  suffer and
permit the execution of every such power as though no such law had been enacted.

                  SECTION 515.      Undertaking for Costs.

                  All parties to this  Indenture  agree,  and each Holder of any
Security by his  acceptance  thereof  shall be deemed to have  agreed,  that any
court may in its  discretion  require,  in any suit for the  enforcement  of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action  taken,  suffered  or omitted by it as  Trustee,  the filing by any party
litigant in such suit of an  undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs,  including  reasonable
attorney's fees,  against any party litigant in such suit,  having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee,  to any suit instituted by any Holder, or group of Holders,  holding in
the aggregate more than 10% in principal  amount of the Outstanding  Securities,
or to any suit  instituted by any Holder for the  enforcement  of the payment of
the principal (or premium,  if any ) or interest on any Security on or after the
respective  Stated  Maturities  expressed in such  Security  (or, in the case of
redemption, on or after the Redemption Date).

                                   ARTICLE SIX


                                   THE TRUSTEE

                  SECTION 601.      Notice of Defaults.

                  The Company shall deliver to the Trustee, within 60 days after
the end of each fiscal year,  an Officer's  Certificate  indicating  whether the
signers  thereof know of any Default that occurred during the previous year. The
Company shall also deliver to the Trustee,  within 30 days after the  occurrence
thereof, written notice of any events which constitute an Event of Default.

                  If a Default or an Event of Default  occurs and is  continuing
and is known to the  Trustee,  the  Trustee  shall  mail to each  Holder  of the
Securities in the manner and to the extent provided in TIA Section 313(c) notice
of the Default or Event of Default within 90 days after the occurrence  thereof;
provided,  however, that, except in the case of a Default or an Event of Default
in the payment of  principal  of (and  premium,  if any,  on) or interest on any
Securities, the Trustee may withhold the notice to the Holders of the Securities
if its board of directors,  a committee of its board of directors or a committee
of its trust officers in good faith  determines that  withholding such notice is
in the interests of the Holders of the Securities.

                  SECTION 602.      Certain Rights of Trustee.

                  (a)......Prior  to the  occurrence of a Default or an Event of
Default of which the Trustee has been  notified as provided in clause  (c)(x) of
this Section below,  or of which by that paragraph the Trustee is deemed to have
notice,  and after the cure or waiver of all Defaults or Events of Default which
may have occurred and, as applicable,  subject to the provisions of TIA Sections
315(a) through 315(d):

                  (i) the Trustee  undertakes  to perform  only those duties and
                  obligations which are set forth specifically in this Indenture
                  and no other  duties or  obligations  shall be  implied to the
                  Trustee;

                  (ii) in the absence of bad faith on its part,  the Trustee may
                  rely  conclusively  as to the truth of the  statements and the
                  correctness   of   the   opinions   expressed   therein   upon
                  certificates   or  opinions   furnished  to  the  Trustee  and
                  conforming to the  requirements of this Indenture;  but in the
                  case  of  any  such  certificates  or  opinions  which  by any
                  provision hereof are required  specifically to be furnished to
                  the Trustee,  the Trustee shall be under a duty to examine the
                  same to determine  whether they conform to the requirements of
                  this Indenture.

                  In case a Default or an Event of Default has  occurred  and is
continuing  hereunder  of which the Trustee has been  notified,  or is deemed to
have notice as  provided in clause  (c)(x) of this  Section  below,  the Trustee
shall  exercise those rights and powers vested in it by this Indenture and shall
use the same  degree of care and skill in their  exercise,  as a prudent  person
would exercise or use under the circumstances in the conduct of his own affairs.

                  (b)......No provisions of this Indenture shall be construed to
release  the  Trustee  from  liability  for its own  negligent  action,  its own
negligent failure to act, or its own willful misconduct, except that:

                  (i) this  paragraph  shall  not be  construed  to  affect  the
                  limitation of the Trustee's duties and obligations provided in
                  clause (a) of this Section 602 or the Trustee's  right to rely
                  on the truth of statements and the  correctness of opinions as
                  provided in clause (a)(ii) of this Section 602;

                  (ii) the Trustee shall not be liable for any error of judgment
                  made in good faith by any one of its officers, unless it shall
                  be established  that the Trustee was negligent in ascertaining
                  the pertinent facts; and

                  (iii) the  Trustee  shall not be liable  with  respect  to any

                  a majority in principal  amount of the  Securities at the time

               c) Except as otherwise provided in subsections (a) and (b) above:

                  (i) the Trustee may  conclusively  rely and shall be protected
                  in acting or refraining from acting,  pursuant to the terms of
                  this Indenture or otherwise, upon any resolution, certificate,

                  established prior to taking,  suffering or omitting any action
                  hereunder,  the  Trustee  (unless  other  evidence  be  herein
                  specifically  prescribed)  may, in the absence of bad faith on

                  request or  direction  of any of the Holders  pursuant to this
                  Indenture,  unless  such  Holders  shall  have  offered to the
                  Trustee  reasonable  security or indemnity  against the costs,
                  expenses and  liabilities  (including fees and expenses of its
                  agents  and  counsel)   which  might  be  incurred  by  it  in
                  compliance with such request or direction;

                  (vi) the Trustee shall not be bound to make any  investigation
                  into,  and may  conclusively  rely upon,  the facts or matters
                  stated in any resolution,  certificate, statement, instrument,

                           (C)       any instrument or document of further 
                                     assurance or collateral assignment,

                           (D)      the validity of the execution by the Company
                                    and the Subsidiary  Guarantors of
                                    this  Indenture,  any supplemental indenture

                           (E)      the  sufficiency  of the  security  for the
                                    Securities  issued  hereunder  or
                                    intended to be secured hereby,

                           (F)      losses as the result of any  investments  
                                    in any fund made at the direction of
                                    the Company, or

                           (G)      any disclosure in any offering memorandum or
                                    similar  document related to the Securities,

                  (x) except for those  Events of Default  specified in Sections
                  501(a) and (b) hereof,  the  Trustee  shall not be required to
                  take notice,  and shall not be deemed to have  notice,  of any
                  Default or Event of  Default  hereunder,  unless  the  Trustee
                  shall be  notified  specifically  of the  Default  or Event of
                  Default in a written instrument or document delivered to it by
                  the Company or by the Holders of at least 25% of the aggregate
                  principal  amount  of  Securities  then  Outstanding.  In  the
                  absence of delivery of a notice satisfying those requirements,
                  the Trustee may assume  conclusively  that there is no Default
                  or Event of  Default,  except  for  those  Events  of  Default
                  specified in Sections 501(a) and (b) hereof.

                  (xi) the  Trustee  shall not be  required  to give any bond or
                  surety  with  respect  to the  execution  of these  trusts and
                  powers or otherwise in respect of the Securities.

                  (xii) the  Registrar,  Paying Agent and  Authenticating  Agent
                  shall be  entitled  to all of the  protections  to  which  the
                  Trustee is entitled hereunder.

                  (xiii)  notwithstanding  anything to the contrary herein,  the
                  Trustee   shall  not  be   responsible   or  liable   for  the
                  appropriateness or compliance of the form of securities issued
                  representing   any  of  the  Securities  with  the  terms  and
                  provisions  of this  Indenture  or any  applicable  federal or
                  state securities law, rule or regulation and the Trustee shall
                  solely   rely  on  the  Company  to  deliver  to  the  Trustee
                  certificates  for  authentication  which comply with the terms
                  and provisions of this Indenture and any applicable federal or
                  state securities law, rule or regulation,  such delivery which
                  shall conclusively evidence such compliance.

                  The  Trustee  shall not be  required to expend or risk its own
funds or otherwise  incur any financial  liability in the  performance of any of
its duties  hereunder,  or in the  exercise of any of its rights or powers if it
shall have  reasonable  grounds for  believing  that  repayment of such funds or
adequate  indemnity against such risk or liability is not reasonably  assured to
it.

                  SECTION 603.      Trustee Not Responsible for Recitals or 
Issuance of Securities.

                  The recitals  contained  herein and in the Securities,  except
for  the  Trustee's  certificates  of  authentication,  shall  be  taken  as the
statements of the Company and the Trustee  assumes no  responsibility  for their
correctness.  The  Trustee  makes  no  representations  as to  the  validity  or
sufficiency of this Indenture, any Subsidiary Guarantee or the Securities except
that the Trustee  represents  that it is duly  authorized to execute and deliver
this  Indenture,   authenticate  the  Securities  and  perform  its  obligations
hereunder and, upon the  effectiveness of the Registration  Statement,  that the
statements  made by it in a Statement of Eligibility on Form T-1 supplied to the
Company are true and accurate,  subject to the qualifications set forth therein.
The Trustee shall not be  accountable  for the use or application by the Company
of Securities  or the proceeds  thereof or any money paid to the Company or upon
the Company's direction under any provision of this Indenture. The Trustee shall
not be  responsible  for the use or  application  of any money  received  by any
Paying Agent other than the Trustee.

                  SECTION 604.      May Hold Securities.

                  The  Trustee,  any Paying  Agent,  any  Registrar or any other
agent of the Company or of the Trustee, in its individual or any other capacity,
may  become  the owner or pledgee of  Securities  and,  subject to TIA  Sections
310(b) and 311,  may  otherwise  deal with the  Company  with the same rights it
would have if it were not Trustee, Paying Agent, Registrar or such other agent.

                  SECTION 605.      Money Held in Trust.

                  Money  held by the  Trustee  in  trust  hereunder  need not be
segregated  from other funds  except to the extent  required by law. The Trustee
shall be under no liability  for interest on any money  received by it hereunder
except as otherwise agreed with the Company.

                  SECTION 606.      Compensation and Reimbursement.

                  The Company agrees:

                  (a) to pay to the Trustee (in its capacity as Trustee,  Paying

         services  rendered by it  hereunder  (which  compensation  shall not be
         limited  by any  provision  of law in regard to the  compensation  of a
         trustee  of  an  express  trust),  including  in  connection  with  the
         investment  by the Trustee  (and/or its  affiliate)  of trust assets in
         certain Permitted Investments as provided in this Indenture;

                  (b)  except  as  otherwise   expressly   provided  herein,  to

         Registrar)  promptly  upon its  request  for all  reasonable  expenses,
         disbursements   and  advances  incurred  or  made  by  the  Trustee  in
         accordance with any provision of this Indenture  (including  securities
         transaction  charges and the reasonable  compensation  and the expenses
         and disbursements of its agents and counsel),  except any such expense,
         disbursement or advance as may be attributable to its negligence or bad
         faith but, with respect to securities  transaction charges, only to the
         extent any such securities  transaction charges have not been waived by
         the Trustee (and/or its affiliate); and

                  (c) to  indemnify  the  Trustee  for,  and to hold it harmless
         against,  any loss, liability or expense incurred without negligence or
         bad  faith  on its  part,  arising  out of or in  connection  with  the
         acceptance  or  administration  of this trust,  including the costs and
         expenses  (including  the  reasonable  expenses  and  disbursements  of
         counsel) of  enforcing  this  Indenture  (including  this  Section 606)
         against the Company or any Subsidiary Guarantor and of defending itself
         against any claim (whether asserted by any Holder or the Company or any
         other  Person)  or  liability  in  connection   with  the  exercise  or
         performance of any of its powers or duties hereunder.

         of such obligations of the Company, the Trustee shall have a lien prior
         to the Securities  upon all property and funds held or collected by the
         Trustee  as  such,  except  funds  held in  trust  for the  payment  of
         principal  of  (and   premium,   if  any)  or  interest  on  particular
         Securities.

                  If  the  Trustee  incurs  expenses  or  renders   services  in
connection  with an Event of Default  specified in Section 501(h) or (i) hereof,
the expenses  (including the reasonable  charges and expenses of its counsel) of

administration under any applicable bankruptcy, insolvency or other similar law.

                  The   provisions   of  this  Section  606  shall  survive  the
termination of this Indenture.

capital  and  surplus of at least  $50,000,000.  If such  corporation  publishes
reports of condition at least annually,  pursuant to law or to the  requirements
of federal, state,  territorial or District of Columbia supervising or examining
authority,  then for the  purposes of this  Section,  the  combined  capital and
surplus  of such  corporation  shall be deemed to be its  combined  capital  and
surplus as set forth in its most recent report of condition so published.  If at
any  time  the  Trustee  shall  cease  to be  eligible  in  accordance  with the
provisions of this Section,  it shall resign  immediately in the manner and with
the effect hereinafter specified in this Article Six.

accordance with the applicable requirements of Section 609 hereof.

                  (b)......The  Trustee may resign at any time by giving written
notice  thereof to the Company.  If the  instrument of acceptance by a successor
Trustee  required by Section  609 hereof  shall not have been  delivered  to the
Trustee  within 30 days  after the  giving of such  notice of  resignation,  the
resigning  Trustee may  petition  any court of  competent  jurisdiction  for the
appointment of a successor Trustee.

Holders  of not less than a  majority  in  principal  amount of the  Outstanding
Securities, delivered to the Trustee and to the Company.

                  (d)......If at any time:

                  (i) the Trustee  shall fail to comply with the  provisions  of
                  TIA  Section  310(b)  after  written  request  therefor by the
                  Company or by any Holder who has been a bona fide  Holder of a
                  Security  for at least six months,  except when the  Trustee's
                  duty to resign is stayed in accordance  with the provisions of
                  TIA Section 310(b), or

                  (ii) the Trustee shall cease to be eligible  under Section 607

                  (iii) the Trustee shall become incapable of acting or shall be
                  adjudged a bankrupt or  insolvent or a receiver of the Trustee
                  or of its property  shall be  appointed or any public  officer
                  shall take charge or control of the Trustee or of its property
                  or affairs for the purpose of rehabilitation,  conservation or
                  liquidation,

then, in any such case, (A) the Company,  by a Board Resolution,  may remove the
Trustee,  or (B) subject to TIA Section  315(e),  any Holder who has been a bona
fide Holder of a Security  for at least six months may, on behalf of himself and
all others similarly situated,  petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

                  (e)......If  the Trustee  shall  resign,  be removed or become
incapable  of acting,  or if a vacancy  shall occur in the office of Trustee for
any  cause,  the  Company,  by a Board  Resolution,  shall  promptly  appoint  a
successor  Trustee.  If,  within  one year after  such  resignation,  removal or
incapability,  or the occurrence of such vacancy,  a successor  Trustee shall be
appointed  by the Holders of a majority in principal  amount of the  Outstanding
Securities  delivered to the Company and the  retiring  Trustee,  the  successor
Trustee so appointed shall,  forthwith upon its acceptance of such  appointment,
become the successor  Trustee and supersede the successor  Trustee  appointed by
the Company. If no successor Trustee shall have been so appointed by the Company
or the Holders  and  accepted  appointment  in the manner  hereinafter  provided
subject to TIA Section  315(e),  any Holder who has been a bona fide Holder of a
Security  for at least six  months  may,  on behalf of  himself  and all  others
similarly  situated,  petition  any  court  of  competent  jurisdiction  for the
appointment of a successor Trustee.

Corporate Trust Office.

                  Every  successor  Trustee  appointed  hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting  such  appointment,  and thereupon the  resignation  or removal of the
retiring Trustee shall become effective and such successor Trustee,  without any
further  act,  deed or  conveyance,  shall  become  vested  with all the rights,
powers,  trusts  and  duties of the  retiring  Trustee;  but,  on request of the
Company or the successor  Trustee,  such retiring Trustee shall, upon payment of
its charges,  execute and deliver an instrument  transferring  to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign,  transfer and deliver to such  successor  Trustee all property and money
held by such retiring Trustee hereunder subject to the retiring Trustee's rights
as provided  under the last sentence of Section 606 hereof.  Upon request of any
such successor  Trustee,  the Company shall execute any and all  instruments for
more fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

                  No successor  Trustee shall accept its  appointment  unless at
the time of such  acceptance  such  successor  Trustee  shall be  qualified  and
eligible under this Article Six.

                  SECTION 610.      Merger, Conversion, Consolidation or 
Succession to Business.

                  Any  corporation  into  which  the  Trustee  may be  merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion  or  consolidation  to which the Trustee shall be a
party,  or  any  corporation  succeeding  to  all  or  substantially  all of the
corporate  trust business of the Trustee,  shall be the successor of the Trustee
hereunder,  provided such corporation shall be otherwise  qualified and eligible
under this Article,  without the execution or filing of any paper or any further
act on the part of any of the parties hereto.  In case any Securities shall have
been  authenticated,  but not  delivered,  by the  Trustee  then in office,  any
successor by merger,  conversion or consolidation to such authenticating Trustee
may adopt such  authentication  and deliver the Securities so authenticated with
the same  effect as if such  successor  Trustee  had itself  authenticated  such
Securities.  In case at that  time any of the  Securities  shall  not have  been
authenticated,  any successor Trustee may authenticate such Securities either in
the name of any predecessor  hereunder or in the name of the successor  Trustee.
In all such cases such  certificates  shall have the full force and effect which
this Indenture  provides that the certificate of  authentication  of the Trustee
shall  have;  provided,  however,  that the  right to adopt the  certificate  of
authentication of any predecessor  Trustee or to authenticate  Securities in the
name of any predecessor  Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

reason of mailing  any  material  pursuant  to a request  made under TIA Section
312(b).

                  SECTION 702.      Reports by Trustee.

                  Within 60 days after May 15 of each year  commencing  with the

                  Delivery of such  reports,  information  and  documents to the

                    CONSOLIDATION, MERGER, AND SALE OF ASSETS

                  SECTION 801.      Company May Consolidate, etc., Only on 
Certain Terms.

                  The Company shall not consolidate  with or merge with or into,
or  convey  or  transfer  or lease in one  transaction  or a series  of  related
transactions,  all or substantially  all of its assets to, another Person unless
each of the following conditions is satisfied:

                  (a)  the  resulting,  surviving  or  transferred  Person  (the
         "Successor  Corporation") is a corporation organized and existing under
         the laws of the United  States or any state  thereof or the District of
         Columbia and (if other than the  Company)  assumes,  by a  supplemental
         indenture in form  satisfactory to the Trustee,  all the obligations of
         the Company under the Securities and this Indenture;

                  (b)      immediately  after  giving  effect to such  
transaction,  no Default or Event of Default exists;

                  (c)  immediately   after  giving  pro  forma  effect  to  such
         transaction  and any  related  financing  transactions,  the  Successor
         Corporation  would be permitted to incur at least $1.00 of Indebtedness
         pursuant to the Consolidated Fixed Charge Coverage Ratio test set forth
         in Section 1010(a);

                  (d) the Company  delivers,  or causes to be delivered,  to the
         Trustee, in form and substance reasonably  satisfactory to the Trustee,
         an Officers'  Certificate and an Opinion of Counsel,  each stating that
         such  transaction  complies with the requirements of this Indenture and
         all conditions precedent have been satisfied; and

                  (e) if the Company is not the  continuing  obligor  under this
         Indenture,  each Subsidiary Guarantor,  unless it is the other party to
         the  transaction   described  above,  has  by  supplemental   indenture
         confirmed  that  its  Subsidiary  Guarantee  applies  to the  Successor
         Corporation's obligations under this Indenture and the Securities.

                  Notwithstanding the foregoing, this Section 801 will not apply
to a conveyance, sale, assignment,  transfer, conveyance or other disposition of
assets  between  or among the  Company  and any of its  Wholly-Owned  Restricted
Subsidiaries or any of the Subsidiary Guarantors. For purposes of the foregoing,
the transfer (by lease,  assignment,  sale or otherwise, in a single transaction
or series of  transactions)  of all or  substantially  all of the  properties or
assets  of  one  or  more  Restricted   Subsidiaries  that  constitutes  all  or
substantially  all of the properties and assets of the Company on a consolidated
basis,  shall be deemed to be the  transfer of all or  substantially  all of the
properties and assets of the Company.

                  SECTION 802.      Successor Substituted.

                  In the event of any  transaction  described  in and  complying
with the conditions listed in Section 801 hereof in which the Company is not the
continuing obligor under this Indenture,  the Successor Corporation shall be the
successor to, and be substituted for, and may exercise every right and power of,
the  Company  under this  Indenture  with the same  effect as if such  Successor
Corporation  had been named as the Company  herein,  and  thereafter the Company
shall be released from its obligations under the Securities and this Indenture.

amend or supplement this Indenture or the Securities  without the consent of any
Holder of the Securities:

                  (i)      to cure any ambiguity, defect or inconsistency;

                 interests of Holders of the Securities in any material respect;

                  (ii)     to provide for uncertificated Securities in addition 
                  to or in place of certificated Securities;

                  (iii) to provide for the assumption by a Successor Corporation
                  of the Company's  obligations  to Holders of Securities in the
                  case  of  a  merger  or   consolidation  or  sale  of  all  or
                  substantially all of the Company's assets;

                  (iv) to make any change  that  would  provide  any  additional
                  rights or benefits to the Holders of  Securities  or that does
                  not  adversely  affect the legal rights  hereunder of any such
                  Holder;

                  (v)      to comply with any requirement of the Commission in

                  (viii)   to secure the Securities; or

                  (ix)     to add new Subsidiary  Guarantors or release  
                  Subsidiary  Guarantors in accordance  with the terms of this 
                  Indenture.

                  Upon  the  request  of  the  Company  accompanied  by a  Board
Resolution  authorizing  the  execution  of any  such  amended  or  supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
903 hereof,  the Trustee  shall join with the  Company in the  execution  of any
amended or supplemental Indenture,  authorized or permitted by the terms of this
Indenture and to make any further  appropriate  agreements and stipulations that
may be therein  contained,  but the Trustee shall not be obligated to enter into
such amended or  supplemental  Indenture that affects its own rights,  duties or
immunities under this Indenture or otherwise.

                  SECTION 902.      With Consent of Holders.

                  (a)......Except  as set forth  herein,  this  Indenture may be

the  Outstanding  Securities  and any  past  Default  or  Event  of  Default  or
compliance  with any provisions may be waived with the consent of the Holders of

                  (c)......It  shall  not be  necessary  for any Act of  Holders
under this Section to approve the particular  form of any proposed  supplemental
indenture,  but it shall be  sufficient  if such Act shall approve the substance
thereof.

                  SECTION 903.      Execution of Supplemental Indentures.

                  In executing,  or accepting the additional  trusts created by,
any  supplemental  indenture  permitted  by this  Article  or the  modifications
thereby of the trusts created by this  Indenture,  the Trustee shall be entitled
to  receive,  and  shall  be fully  protected  in  relying  upon,  an  Officers'
Certificate   and  Opinion  of  Counsel  stating  that  the  execution  of  such
supplemental  indenture is  authorized  or permitted by this  Indenture and that
such supplemental  indenture constitutes the legal, valid and binding obligation
of the Company and each Subsidiary Guarantor subject to the customary exceptions
and such other matters as the Trustee may reasonably  request.  The Trustee may,
but shall not be obligated to, enter into any such supplemental  indenture which
affects the Trustee's own rights,  duties or immunities  under this Indenture or
otherwise.

                  SECTION 904.      Effect of Supplemental Indentures.

                  Upon the execution of any  supplemental  indenture  under this
Article Nine, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

                  SECTION 905.      Conformity with Trust Indenture Act.

                  Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act as then in effect.

                  SECTION 906.      Reference in Securities to Supplemental 
Indentures.

                  Securities  authenticated and delivered after the execution of
any supplemental  indenture  pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental  indenture. If the Company shall so determine,
new Securities so modified as to conform,  in the opinion of the Trustee and the
Company, to any such supplemental  indenture may be prepared and executed by the
Company  and  authenticated  and  delivered  by  the  Trustee  in  exchange  for
Outstanding Securities.

                  SECTION 907.      Notice of Supplemental Indentures.

                  Promptly after the execution by the Company,  each  Subsidiary
Guarantor  and  the  Trustee  of  any  supplemental  indenture  pursuant  to the
provisions of Section 902 hereof,  the Company shall give notice  thereof to the
Holders of each  Outstanding  Security  affected,  in the manner provided for in

supplemental indenture.

                                    COVENANTS

                  SECTION 1001.     Payment of Principal, Premium, if Any, and
Interest.

                  The  Company  covenants  and  agrees  for the  benefit  of the
Holders that it will duly and punctually  pay the principal of (and premium,  if
any)  and  interest  on the  Securities  in  accordance  with  the  terms of the
Securities and this Indenture.

                  SECTION 1002.     Maintenance of Office or Agency.

                  The Company shall  maintain in The City of New York, an office
or agency where  Securities may be presented or surrendered  for payment,  where
Securities may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served.  The Trustee's office located at One State Street,  New
York,  New York 10004 shall be such office or agency of the Company,  unless the
Company shall designate and maintain some other office or agency for one or more
of such purposes. The Company shall give prompt written notice to the Trustee of
any change in the  location  of any such  office or  agency.  If at any time the
Company shall fail to maintain any such required  office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the  Corporate  Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

                  The Company may also from time to time  designate  one or more
other  offices or  agencies  (in or  outside of The City of New York)  where the
Securities may be presented or surrendered  for any or all such purposes and may
from time to time rescind any such designation;  provided, however, that no such
designation  or  rescission  shall in any  manner  relieve  the  Company  of its
obligation  to  maintain  an  office  or agency in The City of New York for such
purposes.  The Company  shall give prompt  written  notice to the Trustee of any
such  designation or rescission and any change in the location of any such other
office or agency.

                  SECTION 1003.  Money for Security Payments to Be Held in Trust

                  If the Company  shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of (or premium,  if any) or
interest on any of the  Securities,  segregate and hold in trust for the benefit
of the Persons  entitled  thereto a sum  sufficient  to pay the principal of (or
premium,  if any) or interest  so becoming  due until such sums shall be paid to
such Persons or  otherwise  disposed of as herein  provided  and shall  promptly
notify the Trustee of its action or failure so to act.

                  Whenever the Company  shall have one or more Paying Agents for
the  Securities,  it shall,  on or before each due date of the  principal of (or
premium,  if any) or interest on any  Securities,  deposit with a Paying Agent a
sum  sufficient  to pay the  principal  (and  premium,  if any) or  interest  so
becoming  due,  such  sum to be held in trust  for the  benefit  of the  Persons
entitled to such principal,  premium or interest,  and (unless such Paying Agent
is the Trustee) the Company shall promptly  notify the Trustee of such action or
any failure so to act.

                  The  Company  shall cause each  Paying  Agent  (other than the
Trustee)  to execute  and  deliver to the  Trustee an  instrument  in which such
Paying Agent shall agree with the  Trustee,  subject to the  provisions  of this
Section, that such Paying Agent shall:

                  (i) hold all sums held by it for the payment of the  principal
                  of (and  premium,  if any) or interest on  Securities in trust
                  for the benefit of the  Persons  entitled  thereto  until such
                  sums shall be paid to such Persons or otherwise disposed of as
                  herein provided;

                  (ii) give the Trustee notice of any default by the Company (or
                  any other  obligor upon the  Securities)  in the making of any
                  payment of principal (and premium, if any) or interest; and

                  (iii) at any time during the  continuance of any such default,
                  upon the written request of the Trustee,  forthwith pay to the
                  Trustee all sums so held in trust by such Paying Agent.

                  The Company may at any time,  for the purpose of obtaining the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying  Agent,  such sums to be held by the Trustee
upon the same  trusts as those upon which such sums were held by the  Company or
such Paying  Agent;  and,  upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further  liability  with respect to
such sums.

<PAGE>

               Any money  deposited with the Trustee or any Paying Agent,  or
then held by the  Company,  in trust for the  payment  of the  principal  of (or
premium,  if any) or interest on any Security and  remaining  unclaimed  for two
years after such principal (and premium,  if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company)  shall be discharged  from such trust;  and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment  thereof,  and all  liability  of the Trustee or such Paying  Agent with
respect  to such  trust  money,  and all  liability  of the  Company  as trustee
thereof,  shall thereupon  cease;  provided,  however,  that the Trustee or such
Paying  Agent,  before  being  required to make any such  repayment,  may at the
expense of the Company cause to be published  once, in a newspaper  published in
the English language,  customarily published on each Business Day and of general
circulation in the Borough of Manhattan,  The City of New York, notice that such
money remains  unclaimed and that, after a date specified  therein,  which shall
not be less  than 30 days  from  the  date of such  publication,  any  unclaimed
balance of such money then remaining shall be repaid to the Company.

                  SECTION 1004.     Corporate Existence.

                  Subject to Article Eight,  the Company shall do or cause to be
done all  things  necessary  to  preserve  and keep in full force and effect its
existence and the existence of each of its Restricted Subsidiaries in accordance
with the  respective  organizational  documents  of the  Company  and each  such
Restricted  Subsidiary and the rights (whether pursuant to charter,  partnership
certificate,  agreement, statute or otherwise), material licenses and franchises
of the Company and each such Restricted Subsidiary;  provided, however, that the
Company  shall not be required to preserve any such right,  license or franchise
or the existence of any Restricted  Subsidiary,  if the Board of Directors shall
determine that the maintenance or preservation thereof is no longer desirable in
the conduct of the business of the Company and its Restricted Subsidiaries taken
as a whole and that the loss  thereof  is not  disadvantageous  in any  material
respect to the Holders.

                  SECTION 1005.     Payment of Taxes and Other Claims.

                  The  Company  shall  pay or  discharge  or cause to be paid or
discharged,  before the same shall become delinquent, (a) all taxes, assessments
and governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income,  profits or property of the Company or any  Subsidiary  and (b)
all material lawful claims for labor, materials and supplies,  which, if unpaid,
might by law become a lien upon the  property of the Company or any  Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax,  assessment,  charge or claim whose
amount,   applicability  or  validity  is  being  contested  in  good  faith  by
appropriate proceedings and for which adequate reserves have been established.

                  SECTION 1006.     Maintenance of Properties and Insurance.

                  The Company shall cause all properties owned by the Company or
any  Subsidiary  of the  Company  or used or held for use in the  conduct of its
business or the business of any  Subsidiary  to be  maintained  and kept in good
condition,  repair and working order and supplied  with all necessary  equipment
and  shall  cause  to be made all  necessary  repairs,  renewals,  replacements,
betterments and improvements  thereof, all as in the judgment of the Company may
be necessary  so that the business  carried on in  connection  therewith  may be
properly and  advantageously  conducted at all times;  provided,  however,  that
nothing in this Section 1006 shall  prevent the Company or any  Subsidiary  from
discontinuing  the  maintenance of any of such properties or disposing of any of
them if such  discontinuance  or disposal  is, in the  judgment of the  Company,
desirable in the conduct of its business or the business of any Subsidiary.

                  The Company will  provide or cause to be provided,  for itself
and its Restricted  Subsidiaries,  insurance against loss or damage of the kinds
customarily  insured against by corporations  similarly situated and owning like
properties,  including,  but not  limited  to,  environmental  damage  liability
insurance  and public  liability  insurance,  with  reputable  insurers  in such
amounts,  with such  deductibles  and by such methods as shall be customary  for
corporations similarly situated in the industry in which the Company or any such
Restricted Subsidiary, as the case may be, is then conducting business.

                  SECTION 1007.     Statement by Officers as to Default.

                  (a)......The  Company shall deliver to the Trustee,  within 60
days  after  the  end of  each  fiscal  year,  an  Officers'  Certificate  as to
compliance by the Company and the  Restricted  Subsidiaries  with all conditions
and covenants under this Indenture.  For purposes of this Section 1007(a),  such
compliance  shall  be  determined  without  regard  to any  period  of  grace or
requirement of notice under this Indenture.

                  (b)......If  any Default has occurred and is continuing  under
this  Indenture,  the  Company  shall  deliver to the Trustee by  registered  or
certified  mail,  telex  or  facsimile  transmission  an  Officers'  Certificate
specifying  such event,  notice or other action within five Business Days of its
occurrence.

                  (c)......If any  Registration  Default (as defined in the Note
Registration Rights Agreement and Warrant Registration Rights Agreement) occurs,
the Company shall  deliver to the Trustee by registered or certified  mail or by
facsimile  transmission an Officers'  Certificate  specifying the nature of such

                  forms,  including a  "Management's  Discussion and Analysis of
                  Financial  Condition  and  Results of  Operations"  and,  with
                  respect to the annual information only, a report on the annual

                  If the  Company  has  designated  any of its  Subsidiaries  as

condition  and results of  operations of the  Unrestricted  Subsidiaries  of the
Company.

                  In addition,  whether or not required by the  Commission,  the
Company will file a copy of all of the  information  and reports  referred to in
clauses (i) and (ii) above with the  Commission for public  availability  within
the time periods specified in the Commission's rules and regulations (unless the

                  SECTION 1009.     Limitation on Sale-Leaseback Transactions.

                  The  Company  will not,  and will not  permit  any  Restricted
Subsidiary to, enter into any  sale-leaseback  transaction  involving any of its
assets or  properties  whether  now owned or  hereafter  acquired,  whereby  the
Company or a Restricted  Subsidiary sells or transfers such assets or properties
and then or  thereafter  leases such assets or properties or any part thereof or
any other assets or properties which the Company or such Restricted  Subsidiary,
as the  case may be,  intends  to use for  substantially  the  same  purpose  or
purposes as the assets or properties sold or transferred.

                  The foregoing restriction does not apply to any sale-leaseback
transaction if:

                  (i) the Company or such Restricted Subsidiary,  as applicable,
                  could have (A) Incurred Indebtedness in an amount equal to the
                  attributable  Indebtedness relating to such sale and leaseback
                  transaction under the Consolidated Fixed Charge Coverage Ratio
                  test in Section 1010(a) and (B) Incurred a Lien to secure such
                  Indebtedness pursuant to Section 1017;

                  (ii) the  gross  cash  proceeds  of that  sale  and  leaseback
                  transaction  are at least equal to the fair market  value,  as
                  determined  in good  faith by the Board of  Directors  and set
                  forth in an Officers' Certificate delivered to the Trustee, of
                  the  property  that is the subject of such sale and  leaseback
                  transaction; and

                  (iii)  the  transfer  of  assets  in that  sale and  leaseback
                  transaction  is  permitted  by, and the  Company  applies  the
                  proceeds of such transaction in compliance with,  Section 1013
                  of this Indenture.

                  SECTION 1010.   Limitation on Indebtedness and Issuance of 
                              Preferred Stock.

         (a) The  Company  will not,  and will not permit any of its  Restricted
Subsidiaries to, Incur any Indebtedness  (including  Acquired  Indebtedness) and
the Company will not issue any Disqualified Stock and will not permit any of its
Restricted  Subsidiaries  to issue any shares of Preferred Stock or Disqualified
Stock; provided,  however, that: (i) the Company may Incur Indebtedness which is
expressly subordinate and junior in right of payment to the Securities, and (ii)
the Company and its Restricted  Subsidiaries may Incur  Indebtedness  (including
Acquired Indebtedness) or issue Disqualified Stock if:
                           (A) the Consolidated  Fixed Charge Coverage Ratio for
                           the Company's most recently ended full fiscal quarter
                           for  which   financial   statements   are   available
                           immediately   preceding   the  date  on  which   such
                           Indebtedness is Incurred or such  Disqualified  Stock
                           is issued would have been (1) if the last day of such
                           fiscal quarter is on or before  December 31, 1999, at
                           least  1.5 to 1,  and  (2) if the  last  day of  such
                           fiscal  quarter is on or after  January  1, 2000,  at
                           least  2.0 to 1, in  each  case  determined  on a pro
                           forma basis as set forth in this Section 1010(a); and

                           (B)      no Default or Event of Default has occurred 
and is continuing.

<PAGE>


         In making the foregoing calculation, pro forma effect will be given to:
(i) the  Incurrence of such  Indebtedness  or the issuance of such  Disqualified
Stock  and  (if  applicable)  the  application  of the net  proceeds  therefrom,
including  to  refinance  other   Indebtedness,   as  if  such  Indebtedness  or
Disqualified  Stock, as the case may be, was Incurred or issued, as the case may
be, and the  application  of such  proceeds  occurred at the  beginning  of such
quarter,  (ii) the  Incurrence,  issuance,  repayment or retirement of any other
Indebtedness or Disqualified Stock by the Company or its Restricted Subsidiaries
since the first day of such  quarter  as if such  Indebtedness  or  Disqualified
Stock was Incurred,  issued,  repaid or retired at the beginning of such quarter
and (iii)  the  acquisition  (whether  by  purchase,  merger  or  otherwise)  or
disposition  (whether by sale,  merger or otherwise)  of any company,  entity or
business acquired or disposed of by the Company or its Restricted  Subsidiaries,
as the case may be, since the first day of such quarter,  as if such acquisition
or  disposition  occurred  at  the  beginning  of  such  quarter.  In  making  a
computation under the foregoing clause (i) or (ii), (A) interest on Indebtedness
bearing a floating  interest  rate will be  computed as if the rate in effect on
the date of computation had been the applicable rate for the entire quarter, (B)
if such  Indebtedness  bears, at the option of the Company,  a fixed or floating
rate of interest,  interest thereon will be computed by applying,  at the option
of the  Company,  either  the  fixed  or  floating  rate and (C) the  amount  of
Indebtedness  under a revolving  credit facility will be computed based upon the
average daily balance of such Indebtedness during such quarter.

         (b) Notwithstanding the foregoing paragraph (a), the Company and any of
its Restricted Subsidiaries may Incur each and all of the following Indebtedness
("Permitted Indebtedness"):

                  (i)  Indebtedness  under the Credit  Facility  and one or more
                  other  loan or  credit  agreements  with one or more  banks or
                  financial institutions; provided, that the aggregate principal
                  amount of all  Indebtedness  of the Company and its Restricted
                  Subsidiaries  outstanding  under  all such  credit  facilities
                  after  giving  effect to such  Incurrence  does not  exceed an
                  amount  equal to the  greater of (A) $25  million and (B) such
                  amount  as,  when  added  to  all  other   Indebtedness   then
                  outstanding,  would  result  in  total  Indebtedness  equal to
                  twenty (20) times the  Adjusted  EBITDA of the Company for the
                  most  recently  ended  fiscal  quarter  for  which   financial
                  statements  are  available  immediately  preceding the date on
                  which such  Indebtedness  was  incurred,  calculated  on a pro
                  forma  basis  in  the  manner  described  in  the  penultimate
                  paragraph of subsection (a) above, less in either case (1) the
                  aggregate amount of all repayments,  optional or mandatory, of
                  the principal of any Indebtedness under a credit facility that
                  have  been  made  by the  Company  or  any  of its  Restricted
                  Subsidiaries  after the second anniversary of the date of this
                  Indenture,   except  for   repayments   in   connection   with
                  Refinancing  Indebtedness (as herein defined)  permitted under
                  clause  (vii)  below,  and  (2),  without   duplication,   the
                  aggregate  amount  of all Net Cash  Proceeds  of  Asset  Sales
                  applied by the Company or any of its  Restricted  Subsidiaries
                  to permanently  reduce the  Indebtedness or commitments  under
                  the credit facilities pursuant to Section 1013;

                  (ii)     Indebtedness  of  the  Company  and  its  Subsidiary 
                  Guarantors represented  by  the Securities and the Subsidiary 
                  Guarantees;

                  (iii)    Existing Indebtedness;

                  (iv)  Indebtedness  owed by the  Company  to any  Wholly-Owned
                  Restricted Subsidiary or owed by a Subsidiary Guarantor to the
                  Company or any Wholly-Owned  Restricted  Subsidiary  (provided
                  that  such  Indebtedness  is  held  by  the  Company  or  such
                  Restricted    Subsidiary    and    constitutes    Subordinated
                  Indebtedness);   provided,   that  the   Incurrence   of  such
                  Indebtedness does not violate Section 1011.

                  (v)  Indebtedness of the Company or any Restricted  Subsidiary
                  arising with respect of Interest  Rate  Agreement  Obligations
                  and Currency Agreement Obligations Incurred for the purpose of
                  fixing or hedging interest rate risk or currency risk;

                  (vi)  Indebtedness  Incurred  by  the  Company  or  any of its
                  Restricted  Subsidiaries  with  respect  to letters of credit,
                  bankers'  acceptances,  surety or  performance  bonds or other
                  instruments  issued  in the  ordinary  course of  business  in
                  amounts and for purposes customary in the Company's industry;

                  (vii)  Indebtedness  Incurred  by  the  Company  or any of the
                  Restricted   Subsidiaries  in  connection  with  or  given  in
                  exchange for the renewal, extension, modification,  amendment,
                  refunding,   defeasance,   refinancing   or   replacement   (a
                  "Refinancing")  of  any  of the  Securities  or  any  Existing
                  Indebtedness or any Indebtedness issued after the Closing Date
                  and not Incurred in violation of this Indenture  ("Refinancing
                  Indebtedness");  provided,  however,  that  (a) the  principal
                  amount of such Refinancing  Indebtedness  shall not exceed the
                  principal  amount  (or  accreted  amount,   if  less)  of  the
                  Indebtedness  so  refinanced  at  the  time   outstanding  (or
                  obtainable under any outstanding  credit  agreement) (plus the
                  premiums  paid in  connection  therewith  and  the  reasonable
                  expenses incurred in connection  therewith);  (b) with respect
                  to  Subordinated  Indebtedness  being  refinanced,  the Stated
                  Maturity of the Refinancing  Indebtedness shall be not earlier
                  than the Stated Maturity of the Indebtedness being refinanced,
                  and such Refinancing  Indebtedness  shall have an Average Life
                  at the time such Refinancing  Indebtedness is incurred that is
                  equal to or greater  than the  remaining  Average  Life of the
                  Indebtedness   being   Refinanced;   (c)   with   respect   to
                  Subordinated  Indebtedness  of the Company  being  refinanced,
                  such Refinancing  Indebtedness shall rank no more senior than,
                  and shall be at least as  subordinated  in right of payment to
                  the Securities as the Indebtedness  being refinanced;  and (d)
                  the  obligor  of such  Refinancing  Indebtedness  shall be the
                  obligor on the Indebtedness being refinanced of the Company or
                  a Restricted Subsidiary;

                  (viii) The  Incurrence by the Company or any of its Restricted
                  Subsidiaries  of  Indebtedness  represented  by Capital  Lease
                  Obligations,    mortgage    financings   or   Purchase   Money
                  Obligations,   in  each  case  Incurred  for  the  purpose  of
                  financing  all or any  part of the  purchase  price or cost of
                  construction  or improvement  of property,  plant or equipment
                  used  in  the  business  of the  Company  or  such  Restricted
                  Subsidiary,  in an  aggregate  principal  amount not to exceed
                  $5.0 million at any time outstanding;

                  (ix) Guarantees by the Company or any Restricted Subsidiary of
                  Indebtedness of the Company or any Restricted  Subsidiary that
                  were permitted to be Incurred pursuant to another provision of
                  this Section 1010;

                  (x)      Guarantees  by any  Restricted  Subsidiary  made in  
                  accordance  with the  provisions of
                  Section 1019;

                  (xi) Incurrence by the Company's Unrestricted Subsidiaries, if
                  any, of non-recourse Indebtedness;  provided, however, that if
                  any such Indebtedness  ceases to be Non-Recourse  Indebtedness
                  of an Unrestricted  Subsidiary,  such event shall be deemed to
                  constitute  an  Incurrence  of  Indebtedness  by a  Restricted
                  Subsidiary  of the  Company  that  was not  permitted  by this
                  clause;

                  Disqualified  Stock;  provided,  in each such  case,  that the
                  amount  thereof is included in Fixed Charges of the Company as
                  accrued; and

                  (xiii)   Indebtedness   of  the  Company  or  any   Restricted
                  Subsidiary  in  addition  to that  described  in  clauses  (i)

                  not exceed $5.0 million at any one time outstanding.

otherwise,  an  "Acquired  Person")  shall  be  deemed  to be  Incurred  by such
Restricted Subsidiary at the time it becomes a Restricted Subsidiary.

         For purposes of determining  compliance  with this Section 1010, in the
event that an item of proposed  Indebtedness meets the criteria of more than one
of the categories of Permitted  Indebtedness  described above, or is entitled to
be Incurred pursuant to subsection (a) of this Section 1010, the Company will be
permitted to classify (or  reclassify)  such item of Indebtedness on the date of
its Incurrence in any manner that complies with this Section 1010.

Securities,  in whole or in part in integral multiples of $10,000, at a purchase

accrued and unpaid  interest,  if any, to the date of purchase  (the  "Change of
Control Purchase Price"),  pursuant to the offer described below (the "Change of

                  Within 30 days  following  any Change of Control,  the Company
shall  notify the  Trustee  thereof  and give  written  notice of such Change of
Control to each Holder by  first-class  mail,  postage  prepaid,  at its address
appearing in the Security  Register,  stating,  among other  things:  (i) that a
Change of Control has occurred and that such Holder has the right to require the

Date to receive  interest  on the  relevant  Interest  Payment  Date);  (ii) the
repurchase date (which shall be a Business Day no earlier than 30 days nor later
than 60 days from the date  such  notice  is  mailed  or such  later  date as is
necessary to comply with  requirements  under the Exchange Act);  (iii) that any
Security not tendered shall continue to accrue interest;  (iv) that,  unless the
Company  defaults in the payment of the Change of Control  Purchase  Price,  any
Security  accepted  for payment  pursuant  to the Change of Control  Offer shall
cease to accrue interest after the Change of Control  purchase date (the "Change
of Control Purchase Date"); (v) that, in order to tender Securities  pursuant to
the Change of  Control  Offer,  a Holder  shall be  required  to  surrender  the
Securities,  with the form entitled  "Option of Holder to Elect Purchase" on the

specified in the notice prior to the close of business on the third Business Day
preceding  the Change of  Control  Purchase  Date;  (vi) that  Holders  shall be
entitled to withdraw their election if the Paying Agent receives, not later than
the close of business on the second Business Day preceding the Change of Control
Purchase Date, a telex,  facsimile transmission or letter setting forth the name
of the Holder, the principal amount of Securities delivered for purchase,  and a
statement that such Holder is withdrawing  his election to have such  Securities
purchased;  (vii) that Holders whose Securities are being purchased only in part
shall be issued new  Securities  equal in  principal  amount to the  unpurchased
portion of the Securities  surrendered,  which unpurchased portion must be equal
to $10,000 in principal amount or an integral multiple thereof; and (viii) other
procedures,  if any,  that the  Holders of  Securities  must  follow in order to

<PAGE>

                  If the  Change  of  Control  Purchase  Date  is on or  after a
Regular  Record Date and on or before the related  Interest  Payment  Date,  any
accrued  interest  will  be paid to the  Person  in  whose  name a  Security  is
registered  at the  close  of  business  on such  Regular  Record  Date,  and no
additional interest will be payable to Holders who tender Securities pursuant to
the Change in Control Offer.

                  On the Change of Control  Purchase Date, the Company shall, to
the extent lawful,  (i) accept for payment  Securities or portions  thereof that
are timely tendered  pursuant to the Change of Control Offer,  (ii) deposit with
the Paying  Agent an amount  equal to the Change of  Control  Purchase  Price in
respect of all  Securities or portions  thereof so tendered and (iii) deliver or
cause to be delivered to the Trustee the Securities so accepted together with an
Officers'  Certificate that states the aggregate  principal amount of Securities
or portions thereof tendered to the Company.

                  The  Paying  Agent  shall  promptly  mail  to each  Holder  of
Securities  so  accepted  payment  in an amount  equal to the  Change of Control
Purchase Price for such Securities,  and the Trustee shall promptly authenticate
and  mail to each  Holder  a new  Security  equal  in  principal  amount  to any
unpurchased  portion of the Securities  surrendered,  if any; provided that each
such new Security shall be in a principal amount of U.S.
$10,000 or an integral multiple thereof.

                  The Company will comply,  to the extent  applicable,  with the
requirements of Section 14(e) of the Exchange Act and any other  securities laws
or  regulations in connection  with the  repurchase of Securities  pursuant to a
Change of Control  Offer.  To the extent that the  provisions of any  securities
laws or  regulations  conflict  herewith,  the  Company  will  comply  with  the
applicable  securities  laws and  regulations  and  shall  not be deemed to have
breached its obligations described herein by virtue thereof.

                  The  Company  will not,  and will not  permit  any  Restricted
Subsidiary to, create any restriction  (other than  restrictions  existing under
Indebtedness  as in  effect  on the  Closing  Date  or in  refinancings  of such
Indebtedness)  that would materially impair the ability of the Company to make a
Change of Control Offer to purchase the Securities or, if such Change of Control
Offer is made, to pay for the Securities tendered for purchase.

                  SECTION 1013.     Limitation on Asset Sales.

                  (a)......The  Company  shall  not,  and shall not  permit  any
Restricted  Subsidiary  to,  consummate any Asset Sale unless (i) the Company or
such Restricted  Subsidiary,  as the case may be, receives  consideration at the
time of such Asset Sale at least equal to the fair market value of the assets or
other  property  sold or  disposed of in the Asset Sale and (ii) at least 75% of
such consideration consists of either cash or Cash Equivalents.

                  (b)......Within 365 days after any Asset Sale, the Company may
elect to apply the Net Cash  Proceeds  from such Asset  Sale to (i)  permanently
reduce or redeem  amounts  outstanding  under the Credit  Facility  or any other
credit facility  referred to in Section  1010(b)(i) or to the repayment of other
senior  indebtedness of the Company or a Restricted  Subsidiary and/or (ii) make
(or enter  into a  legally  binding  agreement  to make) an  Investment,  in, or
acquire assets and  properties  that will be used in the business of the Company
and its  Restricted  Subsidiaries  at the Closing Date.  Any balance of such Net
Cash Proceeds exceeding $10.0 million and not applied or invested as provided in
clauses  (i) and (ii)  within  365 days of such  Asset  Sale,  will be deemed to
constitute  "Excess  Proceeds"  and will be applied to make an offer to purchase
Securities (an "Asset Sale Offer") to the Holders of the Securities. Pending the
final  application  of any such Net Cash Proceeds,  the Company may  temporarily
invest such Net Cash Proceeds in cash or Cash Equivalents.

                  For the purposes of this Section 1013,  the following  will be
deemed to be cash: (x) the assumption by the transferee of  Indebtedness  of the
Company or  Indebtedness  of any  Restricted  Subsidiary  of the Company and the
release of the Company or such Restricted  Subsidiary from all liability on such
Indebtedness  in  connection  with such Asset  Sale (in which  case the  Company
shall,   without  further  action,  be  deemed  to  have  applied  such  assumed
Indebtedness in accordance with clause (i) above of this subsection (b)) and (y)
securities  received by the Company or any Restricted  Subsidiary of the Company
from the  transferee  that are  promptly  (and in any  event  within  120  days)
converted by the Company or such Restricted Subsidiary into cash.

                  (c)......In  the  event of an Asset  Sale  that  requires  the
Company  to make an Asset Sale  Offer  pursuant  to  subsection  (b) above,  the
Company  shall make an Asset Sale Offer to all Holders of  Securities,  on a pro
rata  basis,  in  accordance  with the  procedures  set forth in this  Indenture
(including prorating in the event of oversubscription), of the maximum principal
amount  (expressed as a multiple of $10,000) of Securities that may be purchased
with the  Excess  Proceeds,  at a  purchase  price in cash  equal to 100% of the
principal amount thereof,  plus accrued and unpaid interest, if any, to the date
such  offer to  purchase  is  consummated  . To the  extent  that the  aggregate
purchase price of Securities  tendered pursuant to such Asset Sale Offer is less
than the Net Cash  Proceeds  allotted  to the  purchase of the  Securities,  the
Company  shall  apply the  remaining  Net Cash  Proceeds  to  general  corporate
purposes  that  are  not  prohibited  under  this  Indenture.  If the  aggregate
principal  amount of  Securities  validly  tendered and not withdrawn by Holders
thereof  exceeds the Excess  Proceeds,  the Securities to be purchased  shall be
selected on a pro rata basis. Upon the consummation of any Asset Sale Offer, the
amount of Excess Proceeds will be reset to zero.

<PAGE>

                  (d)......Within  30 days of the date upon  which  the  Company
becomes required to make an Asset Sale Offer, the Company shall mail a notice to
the  Trustee  and to each  Holder in the manner  provided  in Section 106 hereof
stating:  (1) that the Asset Sale Offer is being made pursuant to the provisions
of  Section  1013 of this  Indenture  and that all  Securities  duly and  timely
tendered  shall be accepted  for payment  (except,  as  provided  above,  if the
aggregate  principal  amount as the case may be, of the  Securities  surrendered
exceeds the amount of Excess Proceeds);  (2) the purchase price and the purchase
date (the "Asset Sale  Purchase  Date"),  which date shall be no earlier than 30
days nor later than 60 days from the date such  notice is  mailed;  (3) that any
Securities not tendered shall continue to accrue interest;  (4) that, unless the
Company defaults in the payment of the purchase price,  all Securities  accepted
for payment  pursuant  to the Asset Sale Offer  shall  cease to accrue  interest
after the Asset  Sale  Purchase  Date;  (5) that  Holders  electing  to have any
Securities  purchased  pursuant  to an Asset Sale  Offer  shall be  required  to
surrender  the  Securities,  with the form  entitled  "Option of Holder to Elect
Purchase" on the reverse of the Securities completed, to the Paying Agent at the
address  specified  in the notice  prior to the close of  business  on the third
Business Day preceding the Asset Sale Purchase  Date;  (6) that Holders shall be
entitled to withdraw their election if the Paying Agent receives, not later than
the close of  business  on the  second  Business  Day  preceding  the Asset Sale
Purchase Date, a telex,  facsimile transmission or letter setting forth the name
of the Holder, the principal amount of Securities delivered for purchase,  and a
statement that such Holder is withdrawing  his election to have such  Securities
purchased;  (7) that Holders whose  Securities are being  purchased only in part
shall be issued new  Securities  equal in  principal  amount to the  unpurchased
portion of the Securities  surrendered,  which unpurchased portion must be equal
to $10,000 in principal amount or an integral  multiple  thereof;  (8) any other
procedures  that the Holders of Securities  must follow in order to tender their
Securities;  and (9) the  circumstances  and relevant facts regarding such Asset
Sale.

                  If the  Asset  Sale  Purchase  Date is on or  after a  Regular
Record  Date and on or before the related  Interest  Payment  Date,  any accrued
interest  will be paid to the Person in whose name a Security is  registered  at
the close of business on such Regular  Record Date,  and no additional  interest
will be payable to Holders  who  tender  Securities  pursuant  to the Asset Sale
Offer.

                  The Company shall comply, to the extent  applicable,  with the
requirements  of  Section  14(e) of the  Exchange  Act and any other  applicable
securities  laws or regulations in connection  with the repurchase of Securities
pursuant  to this  Section  1013 and shall not be  deemed to have  breached  its
obligations under this Section 1013 by virtue thereof.

                  SECTION 1014.     Limitation on Transactions With Affiliates.

                  (a)......The  Company  will  not,  and  will  not  permit  any
Restricted Subsidiary to, directly or indirectly,  enter into any transaction or
series  of  related  transactions  (including,  without  limitation,  the  sale,
purchase,  exchange or lease of assets, property or services) with any Affiliate
(other than the Company or a Restricted  Subsidiary  of the Company)  unless (i)
such  transaction  or  series  of  transactions  is on  terms  that  are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
would be available in a comparable  transaction in arm's-length dealings with an
unrelated third party,  and (ii) the Company  delivers to the Trustee,  (A) with
respect to any transaction or series of related transactions involving aggregate
consideration  in excess of $1.0  million,  a Board  Resolution  set forth in an
Officers'  Certificate  certifying  that such  transaction  or series of related
transactions complies with this Section 1014 and has been approved by a majority
of the disinterested  members of the Board of Directors of the Company;  and (B)
with respect to any  transaction or series of transactions  involving  aggregate
consideration in excess of $10.0 million,  an opinion as to the fairness of such
transaction to the Company or such  Restricted  Subsidiary,  as the case may be,
from a financial point of view, issued by an accounting, appraisal or investment
banking firm of national standing.

                  (b)......The provisions of subsection (a) above will not 
                    restrict any of the following:

                  (i) employment  agreements,  compensation or employee  benefit
                  arrangements,   stock  options  or  stock  purchase  plans  or
                  agreements with or for the benefit of any officer, director or
                  employee of the Company entered into in the ordinary course of
                  business and approved by the Board of Directors of the Company
                  (including  customary  fringe  benefits and  reimbursement  or
                  advancement of out of pocket  expenses,  loans to employees in
                  the ordinary course of business,  and director's and officer's
                  liability insurance and indemnification arrangements);

                  (ii)     any  transaction  solely  between  or  among  the 
                  Company  and  any of  its  Restricted
                  Subsidiaries or solely between Restricted Subsidiaries;

                  (iii) the payment of reasonable and customary  regular fees to
                  directors of the Company or any Restricted  Subsidiary who are
                  not employees of the Company or any Restricted Subsidiary; and

                  (iv)     any Restricted Payment not prohibited by Section 1011
                   of this Indenture.

                  SECTION 1015.     Limitation  on  Dividend  and Other  Payment
                   Restrictions  Affecting Restricted Subsidiaries.

the  following:  (i) any  agreement  in  effect  on the  Closing  Date,  and any
extensions,  refinancings,  renewals or replacement of such agreement;  provided
that the encumbrances  and  restrictions in any such  extensions,  refinancings,
renewals or replacements  are no less favorable to the Company or any Restricted
Subsidiary than those  encumbrances  or restrictions in the original  agreement;
(ii) existing under or by reason of applicable  law; (iii) this  Indenture,  the
Securities and the Subsidiary Guarantees; (iv) with respect to any Person or the
property  or assets of such Person  acquired  by the  Company or any  Restricted

contemplation  thereof, which encumbrances or restrictions are not applicable to
any Person or the property or assets of any Person other than such Person or the
property or assets of such Person so acquired; (v) in the case of clause (a)(iv)
of this Section 1015,  (A) that restrict in a customary  manner the  subletting,
assignment  or  transfer  of any  property  or asset  that is a lease,  license,
conveyance or contract or similar  property or asset,  (B) existing by virtue of

otherwise  prohibited  by this  Indenture  or (C)  arising  or  agreed to in the
ordinary course of business, not relating to any Indebtedness,  and that do not,

Indebtedness;  provided  that  the  restrictions  contained  in  the  agreements

being  refinanced;   (viii)  provisions  with  respect  to  the  disposition  or
distribution of assets or property in joint venture agreements and other similar

all of the  Capital  Stock or  assets  of such  Subsidiary,  provided  that such
disposition will comply with Section 1013 of this Indenture.  Nothing  contained
in this Section 1015 shall prevent the Company or any Restricted Subsidiary from
(1)  creating,  incurring,  assuming or suffering  to exist any Liens  otherwise
permitted in Section 1017 of this Indenture or (2) restricting the sale or other
disposition  of  property  or assets  of the  Company  or any of its  Restricted
Subsidiaries  that secure  Indebtedness  of the Company or any of its Restricted
Subsidiaries.

no longer  constitute a Restricted  Subsidiary and any Investment in such Person
remaining after giving effect to such issuance or sale would have been permitted
to be made  under  Section  1011 of this  Indenture  if made on the date of such
issuance or sale; or (iv) the issuance or sale of Common Stock of any Restricted

                  The  Company  will not,  and will not  permit  any  Restricted
Subsidiary to, directly or indirectly,  Incur or suffer to exist any Lien on any
of its assets or properties of any character,  or any shares of Capital Stock or
Indebtedness of any Restricted  Subsidiary,  without making effective  provision
for all of the  Securities  and all other amounts due under this Indenture to be
directly secured equally and ratably with (or, if the obligation or liability to

prior to) the obligation or liability secured by such Lien.

<PAGE>

                                    Subsidiaries.

                  (a)......The  Company will not designate any Subsidiary of the
Company (other than a newly created  Subsidiary in which no Investment in excess
of $1,000 has previously been made) as an "Unrestricted  Subsidiary"  under this
Indenture (a "Designation") after the Closing Date unless:

                  (i)      no Default shall have occurred and be continuing at 
                  the time of or after giving effect   to such Designation; and

                  (ii) the Company would not be prohibited  under this Indenture
                  from making an  Investment  at the time of  Designation  in an
                  amount  (the  "Designation  Amount")  equal to the fair market
                  value of such Restricted Subsidiary on such date.

                  If a Restricted  Subsidiary is  designated as an  Unrestricted
Subsidiary,  all outstanding Investments owned by the Company and its Restricted
Subsidiaries  in the Subsidiary so designated will be deemed to be an Investment
made as of the time of such Designation and will reduce the amount available for
Restricted Payments under Section 1011 for all purposes of this Indenture in the
Designation Amount.  Neither the Company nor any Restricted  Subsidiary shall at
any time (x)  provide a  Guarantee  of or  similar  undertaking  (including  any
undertaking, agreement or instrument evidencing such Indebtedness ) with respect
to any Indebtedness of an Unrestricted Subsidiary; provided that the Company and
its  Restricted  Subsidiaries  may pledge Capital Stock or  Indebtedness  of any
Unrestricted  Subsidiary  on a  nonrecourse  basis such that the  pledgee has no
claim whatsoever against the Company other than to obtain such pledged property;
or (y) be directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary, except to the extent permitted under Section 1011 of this Indenture.

                  (b)......The  Company  will  not  revoke  any  Designation  of
a  Subsidiary  as an  Unrestricted Subsidiary (a "Revocation"), unless:

                  (i)      no Default shall have occurred and be continuing at 
                  the time of and after giving  effect to such Revocation; and

                  (ii)  all  Liens  and   Indebtedness   of  such   Unrestricted
                  Subsidiary  outstanding  immediately following such Revocation
                  shall be deemed to have been  incurred  at such time and shall
                  have been  permitted  to be incurred  for all purposes of this
                  Indenture.

                  All   Designations   and  Revocations  must  be  evidenced  by
resolutions  of the Board of Directors  of the Company  delivered to the Trustee
certifying compliance with the foregoing provisions.

                  SECTION 1019.  Limitations  on Issuances of  Guarantees of  
                    Indebtedness;  Additional Guarantors.

                  The   Company   will  not   permit   any  of  its   Restricted
Subsidiaries,  directly  or  indirectly,  to  Guarantee  or pledge any assets to
secure the payment of any  Indebtedness of the Company under any credit facility
unless  such  Restricted  Subsidiary  simultaneously  executes  and  delivers  a
supplemental  indenture  providing  for  the  Guarantee  of the  payment  of the
Securities by such Restricted Subsidiary on a senior unsecured basis.

                  Notwithstanding  the  preceding   paragraph,   any  Subsidiary
Guarantee  of the  Securities  will  provide  by  its  terms  that  it  will  be
automatically   and   unconditionally   released   and   discharged   under  the
circumstances described in Article Fourteen of this Indenture.

                  SECTION 1020.     Waiver of Certain Covenants.

                  The  Company  or any  Restricted  Subsidiary  may  omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1005 through 1011 and Sections 1013 through 1019, inclusive,  if before
or after the time for such  compliance  the  Holders of at least a  majority  in
principal amount of the Outstanding  Securities,  by Act of such Holders,  waive
such compliance in such instance with such term, provision or condition,  but no
such waiver shall extend to or affect such term,  provision or condition  except
to the  extent  so  expressly  waived,  and,  until  such  waiver  shall  become
effective,  the  obligations  of the  Company  and the duties of the  Trustee in
respect of any such term,  provision or condition shall remain in full force and
effect.

                  SECTION 1021.     Payment for Consent.

                  Neither  the Company  nor any of its  Restricted  Subsidiaries
shall,  directly  or  indirectly,  pay or cause  to be paid  any  consideration,
whether  by way  of  interest,  fee or  otherwise,  to any  Holder  for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities  unless such  consideration is offered to be
paid or is paid to all Holders that consent, waive or agree to amend in the time
frame set forth in the solicitation  documents relating to such consent,  waiver
or agreement.

                            REDEMPTION OF SECURITIES

                  SECTION 1101.     Right of Redemption.

                  The  Securities  may be redeemed at the option of the Company,
in whole or from time to time in part,  at any time on or after  March 2,  2003,
subject to the conditions and at the Redemption  Prices specified in the form of
Security  attached  hereto as Exhibit A, together  with accrued  interest to the
Redemption  Date.  The Securities  will not be subject to any mandatory  sinking
fund redemption prior to maturity.

                  SECTION 1102.     Applicability of Article.

                  Redemption  of  Securities  at the  election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be
made in accordance with such provision and this Article.

                  SECTION 1103.     Election to Redeem; Notice to Trustee.

                  The election of the Company to redeem any Securities  pursuant
to Section 1101 hereof shall be evidenced by a Board Resolution.  In case of any
redemption at the election of the Company,  the Company shall,  at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee),  notify the Trustee of such Redemption Date and
of the  principal  amount of  Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 1104 hereof.

                  SECTION 1104.     Selection by Trustee of Securities to Be 
                                    Redeemed.

                  If  less  than  all the  Securities  are to be  redeemed,  the
particular  Securities  to be redeemed  shall be selected  not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities not
previously  called for redemption,  in compliance  with the  requirements of the
principal national securities exchange or automated quotation system, if any, on
which the  Securities  are  listed  or, if the  Securities  are not  listed on a
national securities exchange or automated system, by lot or by such other method
as the  Trustee in its sole  discretion  shall deem to be fair and  appropriate;
provided,  however,  that no such partial redemption shall reduce the portion of
the principal amount of a Security not redeemed to less than $10,000.

                  The Trustee  shall  promptly  notify the Company in writing of
the  Securities  selected  for  redemption  and,  in the case of any  Securities
selected for partial redemption, the principal amount thereof to be redeemed.

                  For  all  purposes  of  this  Indenture,  unless  the  context
otherwise  requires,  all provisions  relating to redemption of Securities shall
relate,  in the case of any Security redeemed or to be redeemed only in part, to
the portion of the principal  amount of such Security which has been or is to be
redeemed.

                  SECTION 1105.     Notice of Redemption.

                  Notice of redemption shall be given in the manner provided for
in  Section  106  hereof  not less  than 30 nor more  than 60 days  prior to the
Redemption Date, to each Holder of Securities to be redeemed.

                  All notices of redemption shall state:

                  (i)      the Redemption Date,

                  (ii)     the Redemption  Price and the amount of accrued  
                  interest to the Redemption Date payable
                  as provided in Section 1107 hereof, if any,

                  (iii)  if  less  than  all  Outstanding  Securities  are to be
                  redeemed,  the  identification  (and, in the case of a partial
                  redemption,   the   principal   amounts)  of  the   particular
                  Securities to be redeemed,

                  (iv) in case any Security is to be redeemed in part only,  the
                  notice which relates to such Security  shall state that on and
                  after the  Redemption  Date,  upon surrender of such Security,
                  the Holder shall receive,  without  charge,  a new Security or
                  Securities  of  authorized  denominations  for  the  principal
                  amount thereof remaining unredeemed,

                  (v) that on the  Redemption  Date the  Redemption  Price  (and
                  accrued  interest,  if any, to the Redemption  Date payable as
                  provided in Section 1107 hereof)  shall become due and payable
                  upon  each  such  Security,  or  the  portion  thereof,  to be
                  redeemed,  and that interest  thereon shall cease to accrue on
                  and after said date,

                  (vi)     the place or places  where such  Securities  are to 
                  be  surrendered  for  payment of the
                  Redemption Price and accrued interest, if any,

                  (vii)    the CUSIP number and

                  (viii)  the  Section  of  the  Securities  or  this  Indenture
                  pursuant to which the Securities are being redeemed.

                  Notice of  redemption  of  Securities  to be  redeemed  at the
election  of the  Company  shall be given by the  Company  or, at the  Company's
request, by the Trustee in the name and at the expense of the Company.

                  SECTION 1106.     Deposit of Redemption Price.

                  On or  prior  to  10:00  a.m.  (New  York  City  time)  on any
Redemption  Date,  the Company  shall  deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent,  segregate and hold
in trust as  provided  in  Section  1003  hereof)  an amount of money in Dollars
sufficient  to pay the  Redemption  Price of, and accrued  interest  on, all the
Securities which are to be redeemed on that date.

                  SECTION 1107.     Securities Payable on Redemption Date.

                  Notice of  redemption  having  been  given as  aforesaid,  the
Securities  so to be redeemed  shall,  on the  Redemption  Date,  become due and
payable  at the  Redemption  Price  therein  specified  (together  with  accrued
interest,  if any, to the Redemption Date), and from and after such date (unless
the Company  shall  default in the payment of the  Redemption  Price and accrued
interest) such  Securities  shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price,  together with accrued interest,
if any, to the Redemption  Date. If the Redemption Date is on or after a Regular
Record  Date and on or before the related  Interest  Payment  Date,  any accrued
interest  will be paid to the Person in whose name a Security is  registered  at
the close of business on such Regular  Record Date,  and no additional  interest
will be payable to Holders whose Securities are redeemed.

                  If any  Security  called for  redemption  shall not be so paid
upon  surrender  thereof for  redemption,  the principal  (and premium,  if any)
shall,  until paid,  bear interest from the Redemption Date at the rate borne by
the Securities.

                  SECTION 1108.     Securities Redeemed in Part.

                  Any  Security  which is to be  redeemed  only in part shall be
surrendered  at the office or agency of the Company  maintained for such purpose
pursuant  to  Section  1002  hereof  (with,  if the  Company  or the  Trustee so
requires,  due  endorsement  by, or a written  instrument  of  transfer  in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or such  Holder's  attorney duly  authorized in writing),  and the Company shall
execute,  and the Trustee shall  authenticate  and deliver to the Holder of such
Security without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the  unredeemed  portion of the principal of the Security so
surrendered.

                              RANKING OF SECURITIES

                  SECTION 1201.     Ranking.

                  The Securities and the  Subsidiary  Guarantees  will be senior
unsecured  obligations  of the  respective  obligors and will rank pari passu in
right of payment with all other  existing and future senior  obligations  of the
Company and the  Subsidiary  Guarantors,  respectively.  The  Securities and the
Subsidiary  Guarantees will be effectively  subordinated to all of the Company's
and the Subsidiary Guarantors' secured debt, including amounts outstanding under
the Credit Facility and Capital Lease Obligations, to the extent of the value of
the  assets  securing  such  loans.  The  Securities  will also be  structurally
subordinated to all liabilities,  including trade payables, of any Subsidiary of
the Company that is not a Subsidiary Guarantor, if any.

                                ARTICLE THIRTEEN

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1301.     Company Option to Effect Legal Defeasance or
 Covenant Defeasance.

                  The Company by Board  Resolution may, at its option and at any
time,  elect to have  either  Section  1302 or 1303  hereof  be  applied  to all
outstanding  Securities  upon  compliance with the conditions set forth below in
this Article Thirteen.

                  SECTION 1302.     Legal Defeasance and Discharge.

                  Upon the Company's  exercise  under Section 1301 hereof of the
option  applicable  to  this  Section  1302,  the  Company  and  the  Subsidiary
Guarantors  shall be deemed to have been discharged from their  obligations with
respect to all Outstanding  Securities and Subsidiary Guarantees on the date the
conditions set forth in Section 1304 hereof are satisfied  (hereinafter,  "legal
defeasance").  For this purpose, such defeasance means that the Company shall be
deemed to have paid and  discharged the entire  Indebtedness  represented by the
Outstanding  Securities,  which shall  thereafter be deemed to be  "Outstanding"
only for the  purposes  of Section  1305  hereof and the other  Sections of this
Indenture referred to in (i) and (ii) below, and to have satisfied all its other
obligations  under such Securities and this Indenture insofar as such Securities
are  concerned  (and the Trustee,  at the expense of the Company,  shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder:

                  (i) the rights of Holders of outstanding Securities to receive
                  payments in respect of the principal of, premium,  if any, and
                  interest on such Securities when such payments are due,

                  (ii)     the  Company's  obligations  with respect to such  
Securities  under  Sections 304, 305, 308, 1002 and 1003,

                  (iii)    the rights,  powers,  trusts,  duties and  immunities
of the Trustee  hereunder and the Company's obligations in connection therewith,
and

                  (iv)     this Article Thirteen.

         Subject to  compliance  with this  Article  Thirteen,  the  Company may
exercise its option under this Section 1302  notwithstanding  the prior exercise
of its option under Section 1303 hereof with respect to the Securities.

                  SECTION 1303.     Covenant Defeasance.

                  Upon the Company's  exercise  under Section 1301 hereof of the
option  applicable to this Section 1303,  each of the Company and the Subsidiary
Guarantors shall be released from its obligations  under any covenant  contained
in clauses  (b) and (c) of Section 801 and in Sections  1005  through  1019 with
respect to the  Outstanding  Securities on and after the date the conditions set
forth in Section 1304 below are satisfied (hereinafter,  "covenant defeasance"),
and the Securities shall  thereafter be deemed not to be  "Outstanding"  for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the  consequences of any thereof) in connection  with such covenants,  but shall
continue to be deemed  "Outstanding" for all other purposes hereunder.  For this
purpose,  such covenant  defeasance  means that, with respect to the Outstanding
Securities, the Company and any Subsidiary Guarantor may omit to comply with and
shall have no liability  in respect of any term,  condition  or  limitation  set
forth in any such covenant,  whether  directly or  indirectly,  by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such  covenant to any other  provision  herein or in any other  document and
such  omission to comply  shall not  constitute a Default or an Event of Default
under Section 501 (other than Section  501(i)) but,  except as specified  above,
the remainder of this Indenture and such Securities shall be unaffected thereby.

                  SECTION 1304.     Conditions to Legal Defeasance or Covenant 
Defeasance.

<PAGE>

                  The following  shall be the conditions to application  of 
either  Section 1302  or 1303 hereof to the Outstanding Securities:

                  (a) The Company shall  irrevocably have deposited or caused to
         be  deposited  with the  Trustee  (or another  trustee  satisfying  the
         requirements  of Section  607 hereof who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds in
         trust,  specifically  pledged as security for, and dedicated solely to,
         the  benefit  of the  Holders  of  such  Securities,  (i)  cash in U.S.
         Dollars,  or (ii) noncallable U.S.  Government  Obligations (as defined
         herein), or (iii) a combination thereof,  sufficient, in the opinion of
         a nationally recognized firm of independent public accountants,  to pay
         and discharge the  principal of,  premium,  if any, and interest on the
         Outstanding Securities on the Stated Maturity (or upon Redemption Date,
         if applicable) of such  principal,  premium,  if any, or installment of
         interest;  provided  that  the  Trustee  shall  have  been  irrevocably
         instructed to apply such money or the proceeds of such U.S.  Government
         Obligations  to said  payments with respect to the  Securities.  Before
         such a deposit,  the  Company  must give to the  Trustee,  notice as to
         whether  the  Securities  are  being  defeased  to  maturity  or  to  a
         particular   redemption  date.  For  this  purpose,   "U.S.  Government
         Obligations"  means  securities that are (A) direct  obligations of the
         United States of America for the timely payment of which its full faith
         and credit is  pledged or (B)  obligations  of a Person  controlled  or
         supervised by and acting as an agency or  instrumentality of the United
         States  of  America  the  timely  payment  of which is  unconditionally
         guaranteed  as a full faith and credit  obligation by the United States
         of America,  which,  in either case,  are not callable or redeemable at
         the option of the issuer  thereof,  and shall also include a depository
         receipt  issued  by a  bank  (as  defined  in  Section  3(a)(2)  of the
         Securities Act), as custodian with respect to any such U.S.  Government
         Obligation  or a specific  payment of  principal  of or interest on any
         such U.S. Government  Obligation held by such custodian for the account
         of the holder of such  depository  receipt,  provided  that  (except as
         required by law) such custodian is not authorized to make any deduction
         from the amount payable to the holder of such  depository  receipt from
         any amount received by the custodian in respect of the U.S.  Government
         Obligation  or the specific  payment of principal of or interest on the
         U.S. Government Obligation evidenced by such depository receipt.

                  (b) No  Default  or  Event  of  Default  with  respect  to the
         Securities  shall have  occurred and be continuing  either:  (i) on the
         date  of such  deposit  (other  than a  Default  or  Event  of  Default
         resulting  from the borrowing of funds to be applied to such  deposit);
         or (ii),  insofar as Section  501(i) hereof is  concerned,  at any time
         during the period ending on the 91st day after the date of such deposit
         (it being  understood that this condition shall not be deemed satisfied
         until the expiration of such period).

                  (c) Such legal  defeasance  or covenant  defeasance  shall not
         result in a breach or violation of, or constitute a default under,  any
         other material  agreement or instrument  (other than this Indenture) to
         which the Company or any Subsidiary Guarantor is a party or by which it
         is bound.

                  (d) In the case of an election under Section 1302 hereof,  the
         Company  shall  have  delivered  to the  Trustee  an Opinion of Counsel
         reasonably  acceptable to the Trustee  confirming  that (i) the Company
         has received from, or there has been published by, the Internal Revenue
         Service a ruling,  or (ii) since the date of this Indenture,  there has
         been a change in the applicable  federal income tax law, in either case
         to the effect that,  and based thereon such opinion shall confirm that,
         the Holders of the Outstanding  Securities shall not recognize  income,
         gain or loss for federal  income tax purposes as a result of such legal
         defeasance  and shall be  subject  to  federal  income  tax on the same
         amounts,  in the same  manner  and at the same times as would have been
         the case if such legal defeasance had not occurred.

                  (e) In the case of an election under Section 1303 hereof,  the
         Company  shall  have  delivered  to the  Trustee  an Opinion of Counsel
         reasonably acceptable to the Trustee confirming that the Holders of the
         Outstanding  Securities  shall not recognize  income,  gain or loss for
         federal income tax purposes as a result of such covenant defeasance and
         shall be subject to federal income tax on the same amounts, in the same
         manner  and at the  same  times  as  would  have  been the case if such
         covenant defeasance had not occurred.

                  (f) The Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that after the 91st day following the deposit,
         the trust  funds will not be  subject  to the effect of any  applicable
         bankruptcy,  insolvency,   reorganization  or  similar  laws  affecting
         creditors' rights generally.

                  (g)  The  Company  shall  have  delivered  to the  Trustee  an
         Officers'  Certificate  stating  that the  deposit  was not made by the
         Company with the intent of preferring  the Holders of  Securities  over
         the other  creditors  of the  Company  with the  intent  of  defeating,
         hindering, delaying or defrauding creditors of the Company or others.

                  (h)  The  Company  shall  have  delivered  to the  Trustee  an
         Officers'  Certificate and an Opinion of Counsel, each stating that all
         conditions  precedent  relating to the legal defeasance or the covenant
         defeasance have been complied with.

                  SECTION 1305.     Deposited  Money and U.S.  Government  
Obligations to Be Held in Trust;  Other Miscellaneous Provisions.

                  Subject to the  provisions  of the last  paragraph  of Section
1003 hereof, all money and U.S. Government  Obligations  (including the proceeds
thereof) deposited with the Trustee (or other qualifying  trustee,  collectively
for  purposes of this  Section  1305,  the  "Trustee")  pursuant to Section 1304
hereof  in  respect  of the  Outstanding  Securities  shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Securities and
this  Indenture,  to the  payment,  either  directly or through any Paying Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Holders of such  Securities of all sums due and to become due
thereon in respect of principal  (and premium,  if any) and  interest,  but such
money need not be segregated  from other funds except to the extent  required by
law.

                  The Company shall pay and  indemnify  the Trustee  against any
tax, fee or other charge  imposed on or assessed  against the U.S.  Governmental
Obligations  deposited  pursuant  to Section  1304 hereof or the  principal  and
interest  received  in respect  thereof  other  than any such tax,  fee or other
charge  which  by law is for  the  account  of the  Holders  of the  Outstanding
Securities.

                  Anything   in   this   Article   Thirteen   to  the   contrary
notwithstanding,  the Trustee  shall  deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1304 hereof which, in the opinion of a nationally recognized
firm of  independent  public  accountants  expressed in a written  certification
thereof  delivered to the  Trustee,  are in excess of the amount  thereof  which
would then be required to be deposited  to effect an  equivalent  defeasance  or
covenant defeasance, as applicable, in accordance with this Article.

                  SECTION 1306.     Reinstatement.

                  If the  Trustee  or any  Paying  Agent is  unable to apply any
money in accordance  with Section 1305 hereof by reason of any order or judgment
of any court or  governmental  authority  enjoining,  restraining  or  otherwise
prohibiting such application,  then the Company obligations under this Indenture
and the  Securities  shall be revived  and  reinstated  as though no deposit had
occurred pursuant to Section 1302 or 1303 hereof, as the case may be, until such
time as the  Trustee  or Paying  Agent is  permitted  to apply all such money in
accordance  with  Section 1305 hereof;  provided,  however,  that if the Company
makes any  payment of  principal  of (or  premium,  if any) or  interest  on any
Security  following the  reinstatement of its obligations,  the Company shall be
subrogated  to the rights of the  Holders  of such  Securities  to receive  such
payment from the money held by the Trustee or Paying Agent.

                                ARTICLE FOURTEEN


                              SUBSIDIARY GUARANTEES

                  SECTION 1401.     Subsidiary Guarantees.

                  The  Company  will  cause  each  Person  that  currently  is a
Restricted  Subsidiary,  or that  becomes a Restricted  Subsidiary,  to become a
Subsidiary Guarantor as provided in Section 1408 hereof.

                  (a)......Subject  to clause  (b) of this  Section  1401,  each
Subsidiary Guarantor hereby, jointly and severally, on a senior unsecured basis,
guarantees  to each  Holder of a Security  authenticated  and  delivered  by the
Trustee,  and to the Trustee on behalf of each Holder, the punctual payment when
due  of  all  Indenture  Obligations  which,  for  purposes  of  its  Subsidiary
Guarantee, shall also be deemed to include all commissions, fees, charges, costs
and  other  expenses  (including  reasonable  legal  fees and  disbursements  of
counsel)  arising out of or incurred by the Trustee or the Holders in connection
with  the  enforcement  of  any  Subsidiary  Guarantee.   Without  limiting  the
generality of the foregoing,  each Subsidiary Guarantor's liability shall extend
to all amounts that  constitute  part of the Indenture  Obligations and would be
owed by the Company to such Holder or the Trustee  under the  Securities or this
Indenture  but for the fact  that  they  are  unenforceable,  reduced,  limited,
suspended or not allowable due to the existence of a bankruptcy,  reorganization
or similar proceeding involving the Company.

                  (b)......Each  Subsidiary Guarantor and by its acceptance of a
Security  each  Holder  hereby  confirms  that it is the  intention  of all such
parties  that  the  Guarantee  by  such  Subsidiary  Guarantor  pursuant  to its
Subsidiary  Guarantee not  constitute a fraudulent  transfer or  conveyance  for
purposes of the Federal Bankruptcy Code, the Uniform Fraudulent  Conveyance Act,
the Uniform  Fraudulent  Transfer Act or any similar federal or state law or the
provisions of its local law relating to fraudulent  transfer or  conveyance.  To
effectuate the foregoing  intention,  the Holders and each Subsidiary  Guarantor
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary  Guarantee shall be limited to the maximum amount as shall, after
giving effect to all other  contingent and fixed  liabilities of such Subsidiary
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other  Subsidiary  Guarantor in respect of the  obligations  of
such other  Subsidiary  Guarantor under its Subsidiary  Guarantee or pursuant to
paragraph (c) of this Section 1401, result in the obligations of such Subsidiary
Guarantor  under  its  Subsidiary   Guarantee  not   constituting  a  fraudulent
conveyance or fraudulent transfer under federal or state law.

                  (c)......In   order  to   provide   for  just  and   equitable
contribution among the Subsidiary  Guarantors,  the Subsidiary Guarantors agree,
inter  se,  that  in the  event  any  payment  or  distribution  is  made by any
Subsidiary  Guarantor (a "Funding  Guarantor")  under its Subsidiary  Guarantee,
such  Funding  Guarantor  shall be  entitled to a  contribution  from each other
Subsidiary  Guarantor  in a pro rata amount based on the Adjusted Net Assets (as
defined below) of each Subsidiary  Guarantor  (including the Funding  Guarantor)
for all  payments,  damages and  expenses  incurred by the Funding  Guarantor in
discharging  the Indenture  Obligations  of the Company or any other  Subsidiary
Guarantor's obligations with respect to its Subsidiary Guarantee.  "Adjusted Net
Assets" of such  Subsidiary  Guarantor  at any date shall mean the lesser of (x)
the amount by which the fair value of the property of such Subsidiary  Guarantor
exceeds  the  total  amount  of  liabilities,   including,  without  limitation,
contingent  liabilities  (after giving effect to all other fixed and  contingent
liabilities  incurred or assumed on such date), but excluding  liabilities under
the Subsidiary  Guarantee of such Subsidiary  Guarantor at such date and (y) the
amount by which the present fair salable value of the assets of such  Subsidiary
Guarantor  at such date  exceeds  the amount  that shall be  required to pay the
probable  liability of such  Subsidiary  Guarantor  on its debts  (after  giving
effect to all other fixed and contingent liabilities incurred or assumed on such
date),  excluding  debt in respect of the Subsidiary  Guarantee,  as they become
absolute and matured.

                  SECTION 1402.     Guaranty Absolute.

                  Subject  to the  limitations  in  Section  1401  hereof,  each
Subsidiary  Guarantor  guarantees that the Securities shall be paid or performed
strictly in  accordance  with the terms of the  Securities  and this  Indenture,
regardless  of any law,  regulation  or order now or  hereafter in effect in any
jurisdiction  affecting  any of such  terms or the  rights  of any  Holder  with
respect  thereto.  The  obligations  of  each  Subsidiary  Guarantor  under  its
Subsidiary Guarantee are independent of the obligations of the Company under the
Securities and this  Indenture,  and a separate action or actions may be brought
and  prosecuted  against such  Subsidiary  Guarantor  to enforce its  Subsidiary
Guarantee,  irrespective of whether any action is brought against the Company or
any other  Subsidiary  Guarantor or whether the Company or any other  Subsidiary
Guarantor  is  joined in any such  action  or  actions.  The  liability  of each
Subsidiary  Guarantor  under its  Subsidiary  Guarantee  shall be  absolute  and
unconditional  and the liability and  obligations of such  Subsidiary  Guarantor
hereunder  shall not be released,  discharged,  mitigated,  waived,  impaired or
affected in whole or in part by:

<PAGE>

                  (i)      any  lack of  validity  or  enforceability  of this  
                  Indenture  or the  Securities  with respect to the Company or 
                  any  Subsidiary  Guarantor  or any  agreement  or  instrument 
                  relating thereto;

                  (ii) any change in the time, manner or place of payment of, or
                  in any other term of, all or any of the Indenture Obligations,
                  or  any  other  amendment  or  waiver  of or  any  consent  to
                  departure from this  Indenture,  including any increase in the

                  additional credit to the Company or otherwise;

                  (iii)    the failure to give notice to the  Subsidiary

                  (iv)     any taking,  release or amendment  or waiver of or 
                  consent to  departure  from any other
                  guarantee, for all or any of the Indenture Obligations;

                  (v) any failure,  omission,  delay by or inability on the part
                  of the Trustee or the Holders to assert or exercise any right,
                  power or remedy  conferred  on the  Trustee or the  Holders in
                  this Indenture or the Securities;

                  (vi) any change in the corporate  structure,  or  termination,
                  dissolution,  consolidation  or merger of the  Company  or any
                  Subsidiary  Guarantor  with  or into  any  other  Person,  the
                  voluntary or  involuntary  liquidation,  dissolution,  sale or
                  other  disposition of all or  substantially  all the assets of
                  the Company or any Subsidiary  Guarantor,  the  marshalling of
                  the assets and  liabilities  of the Company or any  Subsidiary
                  Guarantor,   the   receivership,    insolvency,    bankruptcy,
                  assignment  for  the  benefit  of  creditors,  reorganization,
                  arrangement,  composition with the creditors,  or readjustment
                  of, or other similar proceedings  affecting the Company or any
                  Subsidiary Guarantor, or any of the assets of any of them;

                  (vii)    the  assignment  of any right,  title or  interest  
                  of the Trustee or any Holder in this Indenture or the 
                  Securities to any other Person; or

                  (viii) any other event or circumstance  (including any statute
                  of  limitations),  whether  foreseen or unforeseen and whether
                  similar  or  dissimilar  to any of the  foregoing,  that might
                  otherwise  constitute a defense  available  to, or a discharge
                  of, the Company or a Subsidiary Guarantor,  other than payment
                  in full of the Indenture  Obligations;  it being the intent of
                  each Subsidiary Guarantor that its obligations hereunder shall
                  not be  discharged  except by  payment  of all  amounts  owing
                  pursuant to this Indenture or the Securities.

                  The Subsidiary  Guarantee of each  Subsidiary  Guarantor shall
continue to be  effective or be  reinstated,  as the case may be, if at any time
any payment of any of the Indenture  Obligations  is rescinded or must otherwise
be returned  by any Holder or the Trustee  upon the  insolvency,  bankruptcy  or
reorganization  of the Company or otherwise,  all as though such payment had not
been made. Each Subsidiary  Guarantor further agrees, to the fullest extent that
it may lawfully do so, that, as between such  Subsidiary  Guarantor,  on the one
hand,  and the Holders and the Trustee,  on the other hand,  (A) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article Five
of this Indenture for the purposes of this Subsidiary Guarantee, notwithstanding
any stay,  injunction  or other  prohibition  preventing  such  acceleration  in
respect  of the  obligations  guaranteed  hereby,  and (B) in the  event  of any
acceleration of such  obligations as provided in Article Five of this Indenture,
such obligations (whether or not due and payable) shall forthwith become due and
payable  by  the  Subsidiary  Guarantor  for  the  purpose  of  this  Subsidiary
Guarantee.

                  SECTION 1403.     Waivers.

                  (a)......Each Subsidiary Guarantor hereby expressly waives (to
the  extent  permitted  by  law)  notice  of the  acceptance  of its  Subsidiary
Guarantee   and   notice   of  the   existence,   renewal,   extension   or  the
non-performance,  non-payment,  or  non-observance on the part of the Company of
any of the terms, covenants,  conditions and provisions of this Indenture or the
Securities  or any  other  notice  whatsoever  to or upon  the  Company  or such
Subsidiary Guarantor with respect to the Indenture Obligations.  Each Subsidiary
Guarantor hereby acknowledges communication to it of the terms of this Indenture
and the Securities and all of the  provisions  herein  contained and consents to
and approves the same. Each Subsidiary Guarantor hereby expressly waives (to the
extent permitted by law) diligence, presentment and protest.

                  (b)......Without  prejudice  to any of the rights or  recourse
which the Trustee or the Holders may have against the Company,  each  Subsidiary
Guarantor  hereby expressly waives (to the extent permitted by law) any right to
require the Trustee or the Holders to:

<PAGE>

                  (i)      initiate  or  exhaust  any  rights,  remedies  or 
                   recourse  against  the  Company,  any Subsidiary Guarantor or
                   any other Person;

                  (ii)     value,  realize  upon,  or dispose of any  security 
                   of the  Company or any other  Person held by the Trustee or 
                   the Holders; or

                  (iii)    initiate  or exhaust any other  remedy  which the 
                  Trustee or the Holders may have in law or equity;

before requiring, becoming entitled to or demanding payment from such Subsidiary
Guarantor under this Subsidiary Guarantee.

                  SECTION 1404.     Subrogation.

                  Each  Subsidiary  Guarantor shall not exercise any rights that
it may acquire by way of subrogation  under this  Subsidiary  Guarantee,  by any
payment made hereunder or otherwise,  until all the Indenture  Obligations shall
have been paid in full. If any amount shall be paid to any Subsidiary  Guarantor
on account  of any such  subrogation  rights at any time when all the  Indenture
Obligations shall not have been paid in full, such amount shall be held in trust
for the benefit of the Holders  and the Trustee and shall  forthwith  be paid to
the  Trustee,  on behalf of the  Holders,  to be  credited  and  applied  to the
Indenture Obligations, whether matured or unmatured.

                  SECTION 1405.     No Waiver; Remedies.

                  No  failure  on the  part  of any  Holder  or the  Trustee  to
exercise,  and no delay in exercising,  any right  hereunder  shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right hereunder
preclude  any other or further  exercise  thereof or the  exercise  of any other
right.  The remedies  herein  provided are  cumulative  and not exclusive of any
remedies provided by law.

                  SECTION 1406.     Continuing Guaranty; No Right of Set-Off; 
Independent Obligation.

                  (a)......This  Subsidiary  Guarantee is a continuing guarantee
of the payment of all Indenture  Obligations  and shall remain in full force and
effect until the payment in full  (subject to Section 1401 hereof) of all of the
Indenture  Obligations  and all other  amounts  payable  under  this  Subsidiary
Guarantee  and shall apply to and secure any  ultimate  balance due or remaining
unpaid to the Trustee or the Holders under this Indenture or the Securities; and
this  Subsidiary  Guarantee  shall not be  considered  as  wholly  or  partially
satisfied by the payment or  liquidation at any time or from time to time of any
sum of money for the time being due or  remaining  unpaid to the  Trustee or the
Holders.

                  (b)......Subject  to  Section  1401  hereof,  each  Subsidiary
Guarantor hereby guarantees that the Indenture  Obligations shall be paid to the
Trustee without set-off or counterclaim or other reduction  whatsoever  (whether
for taxes,  withholding or otherwise) in lawful currency of the United States of
America.

                  (c)......Subject  to  Section  1401  hereof,  each  Subsidiary
Guarantor  guarantees that the Indenture  Obligations  shall be paid strictly in
accordance with their terms regardless of any lack of validity or enforceability
of any of such terms or the rights of the Holders with respect thereto.

                  (d)......Each  Subsidiary  Guarantor's  liability  to  pay  or
perform  or cause  the  performance  of the  Indenture  Obligations  under  this
Subsidiary  Guarantee  shall  arise  forthwith  after  demand for payment by the
Trustee has been given to such Subsidiary  Guarantor in the manner prescribed in
this Indenture.

                  SECTION 1407.     Subsidiary Guarantors May Consolidate, etc.,
on Certain Terms.

                  (a)......Nothing  contained in this Indenture or in any of the
Securities shall prevent any  consolidation or merger of a Subsidiary  Guarantor
with or into  the  Company  or a  Wholly-Owned  Restricted  Subsidiary  or shall
prevent any sale or conveyance  of the property of a Subsidiary  Guarantor as an
entirety  or  substantially  as an  entirety  to the  Company or a  Wholly-Owned
Restricted  Subsidiary,  which  consolidation,  merger,  sale or  conveyance  is
otherwise in accordance with the terms of this Indenture.

                  (b)......Other  than as set  forth  in  paragraph  (a) of this
Section 1407, no Subsidiary Guarantor may merge with or into or consolidate with
any other Person  (whether or not such  Subsidiary  Guarantor  is the  surviving
Person) or convey, sell, assign,  transfer, lease or otherwise dispose of all or
substantially  all its  properties  and  assets to any other  Person  unless (i)
immediately  after such  transaction,  and giving effect thereto,  no Default or
Event of Default has  occurred  and is  continuing;  (ii) such  transaction  was
subject to, and consummated in compliance with, as appropriate,  either Sections
801 and 802 or Section 1013 hereof;  and (iii) the Company shall have  delivered
to the Trustee an Officers'  Certificate and an Opinion of Counsel, each stating
that such transaction complies with the above provisions and that all conditions
precedent relating to such transaction have been complied with.

<PAGE>

                  SECTION 1408.     Additional Subsidiary Guarantors.

                  The Company  will cause each Person that  becomes a Restricted
Subsidiary  after the date of this  Indenture to become a  Subsidiary  Guarantor
with  respect  to the  Indenture  Obligations  by  executing  and  delivering  a
supplemental indenture to this Indenture providing for a Subsidiary Guarantee by
such  Subsidiary  under this  Article  Fourteen  (or under a separate  guarantee
agreement  consistent in all material respects with this Article Fourteen).  The
Company shall deliver to the Trustee,  together with the supplemental  indenture
referred to above,  an Opinion of Counsel  that such  Subsidiary  Guarantee is a
legal, valid, binding and enforceable  obligation of such Subsidiary  Guarantor,
subject  to  customary  local  law  exceptions  and  customary   exceptions  for
bankruptcy and equitable principles.

      SECTION 1409.                 Releases.

                  (a)......In the event of (i) the conveyance, sale, assignment,
transfer or other disposition (by way of merger,  consolidation or otherwise) of
all of the Capital  Stock of a  Subsidiary  Guarantor to a Person other than the
Company or a  Wholly-Owned  Restricted  Subsidiary  of the Company in compliance
with this  Section  1409 and the terms of this  Indenture,  the net  proceeds of
which are applied by the Company in accordance with the applicable provisions of
this  Indenture;  (ii)  a  conveyance,  sale,  assignment,   transfer  or  other
disposition of all or substantially all of the assets of a Subsidiary  Guarantor
(by way of  merger,  consolidation  or  otherwise)  to a Person  other  than the
Company or a  Wholly-Owned  Restricted  Subsidiary  of the Company in compliance
with this Section 1409 and the terms of this Indenture, the Net Cash Proceeds of
which are applied by the Company in  accordance  with Section  1013  hereof;  or
(iii) the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary by
the Board of Directors of the Company,  in compliance  with Section 1018 and the
terms of this  Indenture,  then such Subsidiary  Guarantor (or Person  acquiring
such assets in the event of a sale or other  disposition of all of the assets of
such Subsidiary  Guarantor) shall be deemed  automatically  and  unconditionally
released  from and  discharged  from all of its  obligations  under this Article
Fourteen and its Subsidiary Guarantee without any further action required on the
part of the Trustee or any Holder.

                  (b)......Concurrently  with the  defeasance of the  Securities
under Section 1302 hereof,  or the covenant  defeasance of the Securities  under
Section 1303 hereof, the Subsidiary  Guarantors shall be released from all their
obligations under their Subsidiary Guarantees under this Article Fourteen.

                  (c)......The  Trustee shall deliver an appropriate  instrument
evidencing  such  release upon receipt of a Company  Request  accompanied  by an
Officers'  Certificate  certifying as to the compliance  with this Section 1409.
Any Subsidiary Guarantor not so released shall remain liable for the full amount
of  principal of and interest on the  Securities  as provided in its  Subsidiary
Guarantee.

                  SECTION 1410.     Benefits Acknowledged.

                  Each Subsidiary  Guarantor  acknowledges  that it will receive
direct and indirect  benefits from the financing  arrangements  contemplated  by
this  Indenture and that its guarantee  and waivers  pursuant to its  Subsidiary
Guarantee are knowingly made in contemplation of such benefits.

                  SECTION 1411.     Severability.

                  In case any provision of this  Subsidiary  Guarantee  shall be
invalid, illegal or unenforceable, the validity, legality, and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

                           [REVERSE SIDE OF SECURITY]


                        WASTE SYSTEMS INTERNATIONAL, INC.


                          11 1/2% Senior Note due 2006





1.       Principal and Interest.

                  The Company will pay the principal of this Security on January
15, 2006.

                  The Company  promises to pay interest on the principal  amount
of this Security on each Interest  Payment Date, as set forth below, at the rate
per annum shown above.

                  Interest  will be  payable  semiannually  in  arrears  (to the
holders of record of the Securities at the close of business on the January 1 or
July 1 immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing July 15, 1999.

                  In the  event  that  the  Adjusted  Stockholders'  Equity  (as
defined in the  Indenture) is not at least  $40,000,000  on each of December 31,
1999,  June 30, 2000 and  December 31,  2000,  the interest  rate payable on the
Securities  shall be adjusted on the date  following  each such date to 13%, 14%
and 15% per annum, respectively, except as such rate may be adjusted pursuant to
the Note  Registration  Rights  Agreement  (as  defined  below)  or the  Warrant
Registration Rights Agreement (as defined below) in connection with a default of
the Company's obligations thereunder to file, cause to be declared effective and
keep effective registration statements filed with the Commission .

                  [The Holder of this  Security is entitled to the benefits of a
note  registration  rights  agreement,  dated  as of March 2,  1999,  among  the
Company,  the Subsidiary  Guarantors signatory thereto and the Initial Purchaser
named therein (the "Note Registration Rights Agreement").  The Note Registration
Rights Agreement  provides that, in the event that either (i) the Exchange Offer
Registration Statement (as defined in the Note Registration Rights Agreement) is
not filed with the  Commission  on or prior to the 180th  calendar day following
the date of original issue of the Securities (the "Closing  Date"),  or (ii) the
Exchange Offer  Registration  Statement is not declared effective on or prior to
the 210th  calendar day following the Closing Date, or (iii) the Exchange  Offer
(as defined in the Note Registration  Rights Agreement) is not consummated on or
prior  to  the  240th  calendar  day  following  the  Closing  Date  or a  Shelf
Registration  Statement (as defined in the Note  Registration  Rights Agreement)
with respect to the Registrable  Notes is not declared  effective on or prior to
the 240th  calendar  day  following  the  Closing  Date,  or (iv) either (A) the
Exchange Offer  Registration  Statement ceases to be effective at any time prior
to the time that the Exchange Offer is  consummated  or (B) if  applicable,  the
Shelf  Registration  Statement  has  been  declared  effective  and  such  Shelf
Registration  Statement  ceases to be  effective at any time prior to the second
anniversary  of the Closing Date, the interest rate borne by this Security shall
be increased by an amount equal to 0.50% per annum following such 180-day period
in the case of clause (i) above,  following  such 210-day  period in the case of
clause (ii) above,  following  such  240-day  period in the case of clause (iii)
above, or immediately in the case of clause (iv) above. Such additional interest
will be payable at the same time and in the same  manner as  interest is payable
on the  Securities.  Upon (w) the  filing  of the  Exchange  Offer  Registration
Statement  after the  180-day  period  described  in clause (i)  above,  (x) the
consummation of the Exchange Offer or the effectiveness of a Shelf  Registration
Statement,  as the case may be,  after the 240-day  period  described  in clause
(iii) above, (y) the effectiveness of the Exchange Offer Registration  Statement
after the 210-day period described in clause (ii) above or (z) the effectiveness
of the Exchange Offer Registration Statement or the Shelf Registration Statement
following an event  described in clause (iv) above,  the interest  rate borne by
this Security from the date of such filing,  effectiveness or  consummation,  as
the case may be, will be reduced to the original interest rate if the Company is
otherwise in compliance with this paragraph;  provided,  however, that, if after
any such  reduction in interest  rate, an event  specified in clauses (i), (ii),
(iii) or (iv) above  occurs,  the  interest  rate will again be  increased by an
amount equal to 0.50% per annum and thereafter reduced pursuant to the foregoing
conditions.

         If the Company issues a notice that the Shelf Registration Statement is
unusable  pending  the  announcement  of a  material  corporate  transaction  or
otherwise pursuant to Section 3(k) of the Note Registration Rights Agreement, or
such a notice is required under  applicable  securities laws to be issued by the
Company, and the aggregate number of days in any consecutive twelve-month period
for which all such  notices are issued or required to be issued  exceeds 30 days
in the  aggregate,  then  the  interest  rate  borne  by this  Security  will be
increased  by 0.50% per annum  following  the date that such Shelf  Registration
Statement ceases to be usable beyond the 30-day period permitted above. Upon the
Company  declaring  that the Shelf  Registration  Statement  is usable after the
interest  rate  has been  increased  pursuant  to the  preceding  sentence,  the
interest rate borne by this  Security  will be reduced to the original  interest
rate if the Company is  otherwise  in  compliance  with Section 2(e) of the Note
Registration  Rights  Agreement,  provided,  however,  that if  after  any  such
reduction in interest rate the Shelf  Registration  Statement again ceases to be
usable  beyond the  period  permitted  above,  the  interest  rate will again be
increased and thereafter reduced pursuant to the foregoing provisions.

<PAGE>

        In  addition,   pursuant  to  a  warrant  registration  rights
agreement,  dated  as of  March 2,  1999,  among  the  Company,  the  Subsidiary
Guarantors  signatory  thereto  and the Initial  Purchaser  named  therein  (the
"Warrant  Registration  Rights  Agreement"),  in the event  that  either (i) the
Registration Statement (as defined in the Warrant Registration Rights Agreement)
is not filed with the Commission on or prior to the 180th calendar day following
the Closing Date, (ii) such Registration  Statement is not declared effective on
or prior to the 240th  calendar  day  following  the  Closing  Date or (iii) the
Registration  Statement  ceases to be effective at any time prior to the earlier
of (A) the time when the  Registrable  Securities  (as  defined  in the  Warrant
Registration Rights Agreement) covered by the Registration Statement can be sold
pursuant to Rule 144 under the  Securities  Act without  any  limitations  under
clauses  (c),  (e),  (f) and (h) of Rule 144 and (ii) two years from the Closing
Date (each such event a  "Registration  Default"),  then the per annum  interest
rate borne by the Securities shall be increased by 0.50%  immediately  following
such Registration Default. Upon the filing of the Registration  Statement or the
effectiveness  of the Registration  Statement,  as the case may be, the interest
rate borne by the Securities from the date of such filing or  effectiveness,  as
the case may be, will be reduced to the otherwise  applicable  interest rate set
forth above; provided,  however, that, if after such reduction in interest rate,
a different  event  specified in clause (i),  (ii), or (iii) above  occurs,  the
interest rate may again be increased pursuant to the foregoing provisions. If an
event has  occurred  and is  continuing  as a result  of which the  Registration
Statement  would be  required  to be  amended  or  supplemented  or which  would
otherwise  cause the  Registration  Statement not to be effective and usable for
resale of  Registrable  Securities  during the period  required  by the  Warrant
Registration  Rights  Agreement,  pursuant  to which the  Company  has  issued a
Blackout Notice (as defined in the Warrant  Registration Rights Agreement),  and
the aggregate  number of days in any consecutive  twelve-month  period for which
all such Blackout  Notices are issued or required to be issued  exceeds 30 days,
then the interest  rate borne by the  Securities  will be increased by 0.50% per
annum following the date that such  Registration  Statement  ceases to be usable
beyond such 30 day period permitted above.  Upon the Company  declaring that the
Registration  Statement  is usable after the  interest  rate has been  increased
pursuant to the preceding  sentence,  the interest rate borne by the  Securities
will be reduced to the  otherwise  applicable  interest  rate if the  Company is
otherwise  in  compliance  with  the  Warrant   Registration  Rights  Agreement,
provided,  however,  that if  after  any such  reduction  in  interest  rate the
Registration  Statement  again ceases to be usable  beyond the period  permitted
above, the interest rate will again be increased and thereafter reduced pursuant
to the foregoing provisions.

                  Notwithstanding the foregoing,  in no event shall the interest
rate borne by this  Security  be  increased  pursuant  to the Note  Registration
Rights Agreement or the Warrant Registration Rights Agreement by an amount which
exceeds an aggregate of 0.50% per annum above the otherwise applicable per annum
interest rate.]*

                  Interest  on this  Security  will  accrue from the most recent
date  to  which  interest  has  been  paid  on this  Security  [or the  Security
surrendered in exchange  hereof]** or, if no interest has been paid,  from March
2, 1999;  provided  that,  if there is no  existing  default  in the  payment of
interest and if this  Security is  authenticated  between a Regular  Record Date
referred to on the face hereof and the next  succeeding  Interest  Payment Date,
interest shall accrue from such Interest Payment Date. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

                  The  Company  shall pay  interest  on  overdue  principal  and
premium, if any, and interest on overdue installments of interest, to the extent
lawful, at the rate borne by the Securities.

2.       Method of Payment.

                  The Company will pay interest (except  defaulted  interest) on
the  principal  amount of the  Securities  on each January 15 and July 15 to the
Persons who are Holders (as  reflected in the Security  Register at the close of
business on the January 1 and July 1 (each a "Regular Record Date")  immediately
preceding  the Interest  Payment  Date),  in each case,  even if the Security is
canceled on registration of transfer or registration of exchange,  redemption or
repurchase after such record date; provided that, with respect to the payment of
principal,  the Company  will make  payment to the Holder that  surrenders  this
Security to any Paying Agent on or after January 15, 2006.

                  The Company will pay principal,  premium, if any, and interest
in money of the United  States  that at the time of payment is legal  tender for
payment of public and private debts. At the option of the Company,  interest may
be paid by check  mailed to the address of the Holder  entitled  thereto as such
address  appears in the  Security  Register;  provided  that all payments to the
Holders  who have given wire  transfer  instructions  to the  Trustee  (or other
Paying Agent) by the Regular  Record Date  immediately  preceding  such Interest
Payment  Date  shall be  required  to be made by wire  transfer  of  immediately
available funds to the accounts specified by such Holders.  If a payment date is
a date other than a Business  Day at a place of payment,  payment may be made on
the next  succeeding day that is a Business Day and no interest shall accrue for
the intervening period.

                  Payment of the  principal,  premium,  if any,  and interest on
this  Security,  when and as the same  become due and  payable,  is  guaranteed,
jointly and severally, on a senior unsecured basis, by the Subsidiary Guarantors
referred to below.

3.       Paying Agent and Registrar.

                  Initially,  the  Trustee  will  act as  Authenticating  Agent,
Paying Agent and  Registrar.  The Company may change any  Authenticating  Agent,
Paying Agent or Registrar upon written  notice.  The Company,  any Subsidiary or
any Affiliate of any of them may act as Paying Agent, Registrar or co-registrar.

4.       Indenture; Limitations.

                  The Company issued the Securities  under an Indenture dated as

such  terms.  To the extent  permitted  by  applicable  law, in the event of any
inconsistency between the terms of this Security and the terms of the Indenture,
the terms of the  Indenture  shall  control.  [The  Company  and the  Subsidiary
Guarantors   acknowledge   that  Holders  of  the  Securities   shall  have  the
registration  rights set forth in the Note Registration  Rights  Agreement.  The
Securities  are  also  subject  to  certain  terms   contained  in  the  Warrant
Registration Rights Agreement.]*

                  The Securities are general obligations of the Company.

5.       Ranking.

         The Indebtedness  represented by the Securities ranks in the manner and
to the  extent set forth in the  Indenture.  Each  Holder of a  Security  by his

6.       Redemption.

                  Mandatory  Redemption.  The  Securities  will  not be  subject
to  any  mandatory  sinking  fund redemption prior to maturity.

                  case of any partial  redemption,  selection of the  Securities
                  for redemption will be made
by the Trustee in compliance  with the  requirements  of the principal  national
securities  exchange  or  automated  quotation  system,  if any,  on  which  the
Securities  are  listed  or, if the  Securities  are not  listed  on a  national
securities  exchange or automated  system, by lot or by such other method as the
Trustee in its sole discretion shall deem to be fair and  appropriate;  provided
that no  Security  of $10,000 in  principal  amount or less shall be redeemed in
part.  If any Security is to be redeemed in part only,  the notice of redemption
relating  to such  Security  shall  state the  portion of the  principal  amount
thereof  to be  redeemed.  A new  Security  in  principal  amount  equal  to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation  of the original  Security.  Such new Securities can be obtained at
the offices of the paying agents and transfer agents.

7.       Repurchase upon a Change in Control and Asset Sales.

                  (a) Upon the occurrence of a Change of Control, the Company is

redemption price of 101% of the principal amount thereof, plus accrued interest,
if any, to the date of  purchase  and (b) upon Asset  Sales,  the Company may be
obligated to make offers to purchase  Securities  with the Net Cash  Proceeds of
such Asset Sales at a redemption  price of 100% of the principal  amount thereof
plus accrued interest, if any, to the date of purchase.

8.       Denominations; Transfer; Exchange.

                  The  Securities  are in registered  form without  coupons,  in
denominations  of $10,000 and multiples of $10,000 in excess  thereof.  A Holder
may register  the  transfer or exchange of  Securities  in  accordance  with the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not register
the transfer or exchange of any Securities  selected for redemption  (except the
unredeemed  portion of any Security being  redeemed in part).  Also, it need not
register  the  transfer or exchange  of any  Securities  for a period of 15 days
before a selection of Securities to be redeemed is made.

9.       Persons Deemed Owners.

                  A Holder may be  treated  as the owner of a  Security  for all
purposes.

interest remains  unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company at its request.  After that,  Holders entitled
to the money must look to the Company for payment,  unless an abandoned property
law designates  another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

11.      Discharge Prior to Redemption or Maturity.

                  If  the  Company  irrevocably   deposits,   or  causes  to  be
deposited,  with the Trustee money or U.S. Government  Obligations sufficient to
pay the then outstanding  principal of, premium, if any, and accrued interest on
the  Securities to redemption or maturity,  the Company will be discharged  from
the Indenture and the Securities,  except in certain  circumstances  for certain
sections thereof.

12.      Amendment; Supplement; Waiver.

                  Subject to certain exceptions, the Indenture or the Securities
may be amended or  supplemented  with the  consent of the  Holders of at least a
majority in aggregate  principal amount of the Securities then Outstanding,  and
any existing  default or  compliance  with any  provision may be waived with the
consent of the  Holders  of a  majority  in  aggregate  principal  amount of the
Securities then Outstanding. Without notice to or the consent of any Holder, the
parties  thereto may amend or  supplement  the Indenture or the  Securities  to,
among other things,  cure any ambiguity,  defect or  inconsistency  and make any
change that does not materially adversely affect the rights of any Holder.

obligations of its  predecessor  under the  Securities  and the  Indenture,  the
predecessor Person will be released from those obligations.

15.      Remedies for Events of Default.

                  If an Event of Default,  as defined in the  Indenture,  occurs
and is continuing,  the Trustee or the Holders of not less than 25% in principal
amount of the Securities  then  Outstanding may declare all the Securities to be
immediately due and payable.  If a bankruptcy or insolvency default with respect
to the Company or any of the Subsidiary Guarantors occurs and is continuing, the
Securities  automatically  become  immediately due and payable.  Holders may not
enforce the Indenture or the Securities except as provided in the Indenture. The
Trustee  may  require  indemnity  satisfactory  to it  before  it  enforces  the
Indenture or the Securities. Subject to certain limitations, Holders of at least
a majority in principal amount of the Securities then Outstanding may direct the
Trustee in its exercise of any trust or power.

16.      Subsidiary Guarantees.

premium,  if any, and interest) by the Subsidiary  Guarantors (as defined in the
Indenture)  pursuant to the Subsidiary  Guarantees.  The Indenture requires that
each of the Company's current and future Restricted  Subsidiaries (as defined in
the Indenture) be a Subsidiary  Guarantor.  The Indenture also contains  certain
covenants  restricting  the  ability  of the  Subsidiary  Guarantors  to  merge,
consolidate or conduct certain asset sales.

17.      Trustee Dealings with Company.

                  The Trustee  under the  Indenture,  in its  individual  or any
other capacity, may become the owner or pledgee of Securities and may make loans
to, accept  deposits  from,  perform  services for, and otherwise deal with, the
Company and its Affiliates as if it were not the Trustee.

18.      Authentication.

                  This  Security  shall not be valid until the Trustee signs the
certificate of authentication on the other side of this Security.

                  WARRANT  AGREEMENT,  dated  as  of 
March  2,  1999  (the  "Agreement"),  between  Waste  Systems
International,  Inc., a Delaware corporation (the "Company"),  and IBJ Whitehall
Bank & Trust  Company,  a New York  banking  corporation  as warrant  agent (the
"Warrant Agent").
===============================================================================

                  WHEREAS,   the  Company   proposes  to  issue   warrants,   as
hereinafter  described  (the  "Warrants"),  to  purchase up to an  aggregate  of
1,500,000  shares of Common Stock (as defined  below),  in  connection  with the
offering by Waste  Systems  International,  Inc., a Delaware  corporation  of an
aggregate of $100 million principal amount of the Company's 11 1/2% Senior Notes
due 2006 (the  "Notes")  and  1,500,000  Warrants of the  Company,  each Warrant
entitling  the  holder  thereof  to  purchase  one share of Common  Stock of the
Company.  The Notes and Warrants will be sold in Units (the "Units"),  each Unit
consisting of $10,000 principal amount of Notes and 150 Warrants.

                  WHEREAS,  the  Company  desires  the  Warrant  Agent to act on
behalf of the Company, and the Warrant Agent is willing so to act, in connection
with the issuance of Warrant  Certificates  (as defined below) and other matters
as provided herein.

                  NOW,  THEREFORE,  in  consideration  of the  promises  and the
mutual  agreements  herein  set  forth,  and for the  purpose  of  defining  the
respective  rights and  obligations  of the Company,  the Warrant  Agent and the
Holders (as defined below), the parties hereto agree as follows:

SECTION 1.........Certain  Definitions.  As used in this  Agreement,  the 
               following  terms shall have the following respective meanings:

                  "Affiliate"  of any Person means any other Person  directly or
indirectly  controlling  or  controlled  by or under  direct or indirect  common
control with such Person. For purposes of this definition, "control" (including,
with correlative meanings,  the terms "controlling,"  "controlled by" and "under
common  control  with"),  as used with  respect  to any  Person  shall  mean the
possession,  directly  or  indirectly,  of the  power to  direct  or  cause  the
direction  of the  management  or policies  of such  specified  Person,  whether
through the ownership of voting securities, by agreement or otherwise;  provided
that  beneficial  ownership of 10% or more of the voting  securities of a Person
shall be deemed to be control.

                  "Applicable Procedures" means, with respect to any transfer or
exchange of or for  beneficial  interests in any Global  Warrant,  the rules and
procedures of the Depositary that apply to such transfer or exchange.

                  "Business Day" means any day other than a Legal Holiday.

                  "Cashless  Exercise"  means the exercise of a Warrant  without
the  payment  of cash,  by  reducing  the number of  Warrant  Shares  that would
otherwise have been  obtainable upon the exercise of such Warrant and payment of
the  Exercise  Price in cash so as to yield a number  of  Warrant  Shares  to be
issued  upon such  Cashless  Exercise  equal to the product of (A) the number of
shares of Common Stock for which the Warrant is  exercisable  as of the Exercise
Date (if the  Exercise  Price were  being paid in cash) or such lower  number of
shares for which it is exercised and (B) the Cashless Exercise Ratio.

                  "Cashless  Exercise Ratio" means a fraction,  the numerator of
which is the  excess of the then  Current  Market  Price per share of the Common
Stock on the Exercise Date over the Exercise  Price per share as of the Exercise
Date and the  denominator of which is the then Current Market Price per share of
the Common Stock on the Exercise Date.

         Persons  who  take  delivery  thereof  in the  form of an  Unrestricted
         Definitive Warrant if:

         substantially  the following form:

         "THIS  GLOBAL  WARRANT  IS HELD BY THE  DEPOSITARY  (AS  DEFINED IN THE

in whole and not in part,  each such  Global  Warrant  shall be  returned  to or

hereof. At any time prior to such cancellation,  if any beneficial interest in a
Global Warrant is exercised or exchanged for or transferred to a Person who will
take  delivery  thereof in the form of a beneficial  interest in another  Global
Warrant or for Definitive  Warrants,  the amount of Warrants represented by such
Global Warrant shall be reduced  accordingly and an endorsement shall be made on
such Global  Warrant by the Warrant Agent or by the  Depositary at the direction
of the Warrant Agent to reflect such reduction;  and if the beneficial  interest
is being exchanged for or transferred to a Person who will take delivery thereof
in the form of a  beneficial  interest  in another  Global  Warrant,  such other
Global Warrant shall be increased  accordingly and an endorsement  shall be made
on  such  Global  Warrant  by the  Warrant  Agent  or by the  Depositary  at the
direction of the Warrant Agent to reflect such increase.

such orders or instructions. As to any Opinions of Counsel delivered pursuant to
this Section 3.5, the Warrant  Registrar may exclusively rely upon, and be fully
protected in relying upon, such Opinions.

3.6.              Replacement Warrants.

                  In case any of the Warrant  Certificates  shall be  mutilated,
lost,  stolen or  destroyed,  the  Company may in its  discretion  issue and the
Warrant  Agent may,  countersign,  in  exchange  and  substitution  for and upon
cancellation  of  the  mutilated  Warrant   Certificate,   or  in  lieu  of  and
substitution  for the  Warrant  Certificate  lost,  stolen or  destroyed,  a new
Warrant  Certificate  of like tenor and  representing  an  equivalent  number of
Warrants,  but only upon  receipt of  evidence  reasonably  satisfactory  to the
Company and the Warrant Agent of such loss, theft or destruction of such Warrant
Certificate.  If required by the Warrant Agent or the Company, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Warrant
Agent and the Company to protect the Company,  the Warrant Agent,  and any other
agent for  purposes of the  countersignature  from any loss that any of them may
suffer  if a  Warrant  is  replaced.  Applicants  for  such  substitute  Warrant
Certificates  shall also comply with such other  reasonable  regulations and pay
such  other  reasonable  charges  as the  Company  and  the  Warrant  Agent  may
prescribe. The Company may charge for its expenses in replacing a Warrant.

                  Every  replacement  Warrant  is an  additional  warrant of the
Company and shall be entitled to all of the benefits of this  Warrant  Agreement
equally and proportionately with all other Warrants duly issued hereunder.

3.7.              Temporary Warrants.

                  Until  certificates   representing   Warrants  are  ready  for
delivery,  the Company may prepare  and the  Warrant  Agent,  upon  receipt of a
Warrant  Countersignature  Order,  shall  issue  temporary  Warrants.  Temporary
Warrants shall be  substantially  in the form of  certificated  Warrants but may
have variations that the Company  considers  appropriate for temporary  Warrants
and as shall be reasonably acceptable to the Warrant Agent. Without unreasonable
delay,  the  Company  shall  prepare and the  Warrant  Agent  shall  countersign
definitive Warrants in exchange for temporary Warrants.

                  Holders of temporary  Warrants shall be entitled to all of the
benefits of this Warrant Agreement.

3.8.              Cancellation.

                  Subject to Section 3.5(h) hereof,  the Company at any time may
deliver Warrants to the Warrant Agent for  cancellation.  The Warrant  Registrar
shall  forward  to the  Warrant  Agent  any  Warrants  surrendered  to them  for
registration  of transfer,  exchange or exercise.  The Warrant  Agent and no one
else  shall  cancel all  Warrants  surrendered  for  registration  of  transfer,
exchange,  exercise,  replacement or cancellation and shall return such canceled
Warrants to the  Company  (subject to the record  retention  requirement  of the
Exchange Act).  The Company may not issue new Warrants to replace  Warrants that
have been  exercised  or that  have  been  delivered  to the  Warrant  Agent for
cancellation.

SECTION 4.        Separation  of Warrants.  The Notes and Warrants  shall be  
                  separately  transferable  immediately
upon issuance.

SECTION 5.        Registration and Countersignature.  
                  (a) The Warrant Agent, 
                  on behalf of the Company, shall number and register the 
                  Warrant Certificates in a register as they are issued 
                  by the Company.

                  (b)  Warrant  Certificates  shall be manually  countersigned  
by the Warrant  Agent and shall not be valid for any purpose unless so 
countersigned.

                  (c) The Company  and the Warrant  Agent may deem and treat the
Holder(s)  of  the  Warrant   Certificates  as  the  absolute  owner(s)  thereof
(notwithstanding  any  notation of ownership  or other  writing  thereon made by
anyone),  for all purposes,  and neither the Company nor the Warrant Agent shall
be affected by any notice to the contrary.

SECTION 6. Terms of Warrants; Exercise of Warrants. Subject to the terms of this
Agreement,  each  Warrant  Holder  shall have the right,  which may be exercised
commencing  at the opening of business on any Exercise Date and until 5:00 p.m.,
New York City time on the Expiration Date to receive from the Company the number
of fully paid and nonassessable  Warrant Shares which the Holder may at the time
be entitled to receive on exercise of such  Warrants and payment of the Exercise
Price then in effect for such Warrant  Shares;  provided that no Warrant  Holder
shall be entitled to exercise such Holder's Warrants at any time, unless, at the
time of exercise  (A) (i) a  registration  statement  under the  Securities  Act
relating to the Warrant Shares has been filed with,  and declared  effective by,
the  Commission,  and  no  stop  order  suspending  the  effectiveness  of  such
registration statement has been issued by the Commission or (ii) the issuance of
the Warrant Shares is permitted  pursuant to an exemption from the  registration
requirements of the Securities Act and (B) such Warrant Shares are qualified for
sale or exempt from  qualification  under the applicable  securities laws of the
states in which the various  holders of the Warrants or other Persons to whom it
is  proposed  that the  Warrant  Shares be issued on  exercise  of the  Warrants
reside.  Each Warrant not exercised  prior to 5:00 p.m.,  New York City time, on
the Expiration  Date shall become void and all rights  thereunder and all rights
in  respect  thereof  under  this  Agreement  shall  cease as of such  time.  No
adjustments as to dividends will be made upon exercise of the Warrants.

                  The  Company  shall give notice not less than 90, and not more
than  120,  days  prior  to the  Expiration  Date  to the  Holders  of all  then
outstanding  Warrants to the effect that the Warrants will  terminate and become
void as of 5:00 p.m., New York City time, on the Expiration Date. If the Company
fails to give such notice,  the Warrants will not expire until 90 days after the
Company gives such notice,  provided in no event will Holders be entitled to any
damages or other remedy for the Company's failure to give such notice other than
any such extension.

                  In order to exercise all or any of the Warrants represented by
a Warrant  Certificate,  (i)(A) in the case of Definitive  Warrants,  the Holder
thereof must  surrender for exercise the Warrant  Certificate  to the Company at
the office of the Warrant Agent at its New York corporate  trust office,  (B) in
the  case  of  a  beneficial  interest  in  a  Global  Warrant,  the  exercising
Participant  whose  name  appears  on  a  securities  position  listing  of  the
Depositary  as the  holder of such  beneficial  interest  must  comply  with the
Applicable  Procedures  relating to the exercise of such beneficial  interest in
such  Global  Warrant  and (C) in the  case  of  both  the  Global  Warrant  and
Definitive Warrants, the Holder thereof or the Participant,  as applicable, must
deliver to the Company at the office of the  Warrant  Agent the form of election
to purchase on the reverse  thereof duly filled in and signed,  which  signature
shall  be  medallion  guaranteed  by  an  institution  which  is a  member  of a
Securities Transfer Association recognized signature guarantee program, and (ii)
present  payment to the  Warrant  Agent for the  account  of the  Company of the
Exercise  Price,  which  is set  forth  in the form of  Warrant  Certificate  as
adjusted  as herein  provided,  for the number of  Warrant  Shares in respect of
which such  Warrants  are then  exercised.  For purposes of the  foregoing,  the
Warrant Agent is entitled to conclusively rely on written instructions  received
from the Depositary  regarding any exercise of Warrants  represented by a Global
Warrant.

                  Payment of the aggregate  Exercise  Price shall be made (i) in
cash by wire  transfer or by  certified or official  bank check,  payable to the
order of the Company in United States dollars or (ii) by a Cashless Exercise for
any or all of the shares of Common Stock.

                  When a Holder  surrenders a Warrant  Certificate in connection
with an  option to elect a  Cashless  Exercise,  the  number of shares of Common
Stock  deliverable  upon such Cashless  Exercise shall be equal to the number of
shares of Common Stock  issuable  upon the exercise of Warrants  that the Holder
specifies are to be exercised pursuant to a Cashless Exercise  multiplied by the
Cashless  Exercise  Ratio.  The  exercise of  Warrants by Holders of  beneficial
interest  in the  Global  Warrant  shall be  effected  in  accordance  with this
Agreement and the procedures of the Depositary therefor.

<PAGE>

                  Subject to the provisions of Section 7 hereof,  upon surrender
of Warrants and payment of the  Exercise  Price as provided  above,  the Warrant
Agent  shall  thereupon  promptly  notify the  Company,  and the  Company  shall
promptly  transfer to the Holder of such Warrant  Certificate a  certificate  or
certificates for the appropriate number of Warrant Shares or other securities or
property  (including  any money) to which the Holder is entitled,  registered or
otherwise  placed in, or  payable to the order of,  such name or names as may be
directed  in  writing by the  Holder,  and shall  deliver  such  certificate  or
certificates  representing  the  Warrant  Shares  and any  other  securities  or
property  (including any money) to the person or persons entitled to receive the
same,  together  with an  amount in cash in lieu of any  fraction  of a share as
provided in Section 13 hereof. Any such certificate or certificates representing
the  Warrant  Shares  shall be  deemed  to have been  issued  and any  person so
designated to be named therein shall be deemed to have become a Holder of record
of such  Warrant  Shares as of the date of the  surrender  of such  Warrants and
payment of the Exercise Price.

                  The Warrants shall be  exercisable  commencing on the Exercise
Date,  at the  election of the Holders  thereof,  either in full or from time to
time in part. If less than all the Warrants  represented by a Definitive Warrant
are exercised, such Definitive Warrant shall be surrendered and a new Definitive
Warrant  of the  same  tenor  and for the  number  of  Warrants  which  were not
exercised  shall be executed by the Company and  delivered to the Warrant  Agent
and the Warrant Agent shall countersign the new Definitive  Warrant,  registered
in such name or names as may be  directed  in writing by the  Holder,  and shall
deliver the new Definitive  Warrant to the Person or Persons entitled to receive
the same.  The  Warrant  Agent shall make such  notations  on the  "Schedule  of
Exchanges  of  Interests  on the Global  Warrant" to each Global  Warrant as are
required  to reflect any change in the number of  Warrants  represented  by such
Global Warrant  resulting from any exercise in accordance with the terms hereof.
All Warrant Certificates surrendered upon exercise of Warrants shall be canceled
by the Warrant Agent. Such canceled Warrant  Certificates shall then be disposed
of by the Warrant  Agent in a manner  satisfactory  to the Company.  The Warrant
Agent shall account  promptly to the Company with respect to Warrants  exercised
and concurrently pay to the Company all monies received by the Warrant Agent for
the purchase of the Warrant Shares  through the exercise of such  Warrants.  The
Warrant  Agent shall keep  copies of this  Agreement  and any  notices  given or
received  hereunder  by or from the  Company  available  for  inspection  by the
Holders during normal business hours at its office. The Company shall supply the
Warrant Agent from time to time with such numbers of copies of this Agreement as
the Warrant Agent may reasonably request.

                  All  certificates  representing  Warrant  Shares  issued  in a
transaction  exempt from  registration  under the  Securities Act shall bear the
legend  in  substantially  the form set  forth in  Section  3.5(g)(i)(A)  hereof
(provided  that if no legend is  required  none  shall be placed on the  Warrant
Shares).

SECTION 7. Payment of Taxes.  The Company shall pay all documentary  stamp taxes
attributable  to the  initial  issuance of Warrant  Shares upon the  exercise of
Warrants;  provided  that the  Company  shall not be  required to pay any tax or
taxes which may be payable in respect of any  transfer  involved in the issue of
any Warrant  Certificates or any certificates for Warrant Shares in a name other
than that of the Holder of a Warrant  Certificate  surrendered upon the exercise
of a Warrant,  and the Company  shall not be  required to issue or deliver  such
Warrant  Certificates  unless or until  the  person or  persons  requesting  the
issuance  thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

SECTION 8.        Reservation of Warrant Shares.
(a) The  Company  shall at all  times  reserve  and keep  available,  free  from
preemptive  rights,  out of the aggregate of its authorized but unissued  Common
Stock or its  authorized  and issued Common Stock held in its treasury,  for the
purpose of enabling it to satisfy any  obligation to issue  Warrant  Shares upon
exercise of  Warrants,  the maximum  number of shares of Common  Stock which may
then be deliverable upon the exercise of all outstanding Warrants.

(b) The Company or, if  appointed by the  Company,  the  transfer  agent for the
Common Stock (the "Transfer Agent") and every subsequent  transfer agent for any
shares of the Company's  capital stock  issuable upon the exercise of any of the
rights of purchase aforesaid will be irrevocably  authorized and directed at all
times to reserve such number of authorized  shares as shall be required for such
purpose.  The  Company  shall  keep a copy of this  Agreement  on file  with the
Transfer  Agent and with every  subsequent  transfer agent for any shares of the
Company's  capital  stock  issuable  upon the exercise of the rights of purchase
represented  by the Warrants.  The Company shall supply such Transfer Agent with
duly executed certificates for such purposes and shall provide or otherwise make
available  any cash which may be payable as provided  in Section 13 hereof.  The
Company shall furnish such Transfer  Agent a copy of all notices of  adjustments
and  certificates  related  thereto,  transmitted to each Holder of the Warrants
pursuant to Section 14 hereof. (c) Before taking any action which would cause an
adjustment  pursuant to Sections  10 or 12 hereof to reduce the  Exercise  Price
below the then par value (if any) of the Warrant  Shares,  the Company will take
any  corporate  action  which may, in the  opinion of its counsel  (which may be
counsel  employed by the  Company),  be  necessary in order that the Company may
validly and legally  issue fully paid and  nonassessable  Warrant  Shares at the
Exercise Price as so adjusted. (d) The Company covenants that all Warrant Shares
which may be issued upon  exercise of Warrants in  accordance  with the terms of
this Agreement  (including the terms of the Exercise Price) will, upon issue, be
duly and validly issued, fully paid and nonassessable, free of preemptive rights
and free from all taxes,  liens,  charges and security interests with respect to
the issue  thereof  (other  than  those  created  by the  Holders).  SECTION  9.
Obtaining Stock Exchange  Listings.  The Company will from time to time take all
action which may be necessary so that the Warrant Shares, immediately upon their
issuance  upon  the  exercise  of  Warrants,  will be  listed  on the  principal
securities  exchanges and markets  (including,  without  limitation,  the Nasdaq
SmallCap  Market)  within the United  States of America,  if any, on which other
shares of Common  Stock are then  listed.  The Company  will obtain and keep all
required permits and records in connection with such listing.

SECTION 10.  Adjustment of Exercise Price and Number of Warrant Shares Issuable.
The number and kind of shares  purchasable upon the exercise of Warrants and the
Exercise Price shall be subject to adjustment from time to time as follows:  (a)
Stock Splits,  Combinations,  etc. In case the Company shall hereafter (A) pay a
dividend  or make a  distribution  on its Common  Stock in shares of its capital
stock  (whether  shares of Common Stock or of capital stock of any other class),
(B)  subdivide  its  outstanding   shares  of  Common  Stock,  (C)  combine  its
outstanding  shares of Common Stock into a smaller number of shares or (D) issue
by reclassification of its shares of Common Stock any shares of capital stock of
the Company,  the Exercise Price in effect immediately prior to such action and,
if  applicable,  the type of security  issuable  upon any  exercise of a Warrant
shall be adjusted so that the Holder of any Warrant  thereafter  exercised shall
be entitled to receive upon payment of the Exercise Price the kind and amount of
shares of  capital  stock of the  Company  which  such  Holder  would have owned
immediately  following such action had such Warrant been  exercised  immediately
prior  thereto.  An  adjustment  made  pursuant to this  paragraph  shall become
effective  immediately after the record date in the case of a dividend and shall
become  effective  immediately  after  the  effective  date  in  the  case  of a
subdivision,  combination or reclassification.  If, as a result of an adjustment
made pursuant to this paragraph,  the Holder of any Warrant thereafter exercised
shall become  entitled to receive shares of two or more classes of capital stock
of the Company, the Board of Directors of the Company (whose determination shall
be conclusive)  shall  determine the  allocation of the adjusted  Exercise Price
between or among shares of such classes of capital stock.

(b)   Reclassification,   Combinations,   Mergers,   etc.   In   case   of   any
reclassification  or change of outstanding  shares of Common Stock issuable upon
exercise of the  Warrants  (other than as set forth in  paragraph  (a) above and
other than a change in par value,  or from par value to no par value, or from no
par value to par value or as a result of a subdivision  or  combination),  or in
case of any  consolidation  or  merger  of the  Company  with  or  into  another
corporation  (other  than a  merger  in  which  the  Company  is the  continuing
corporation and which does not result in any  reclassification  or change of the
then  outstanding  shares of Common Stock or other capital  stock  issuable upon
exercise  of the  Warrants)  or in case of any  sale or  conveyance  to  another
corporation of the property of the Company as an entirety or substantially as an
entirety, except any such transactions covered by paragraph (e) below then, as a
condition  of such  reclassification,  change,  consolidation,  merger,  sale or
conveyance,  the Company or such a successor or purchasing  corporation,  as the
case may be,  shall  forthwith  make lawful and adequate  provision  whereby the
Holder of such  Warrant  then  outstanding  shall have the right  thereafter  to
receive on  exercise  of such  Warrant the kind and amount of shares of stock or
other  securities or property  receivable  upon such  reclassification,  change,
consolidation, merger, sale or conveyance by a Holder of the number of shares of
Common Stock  issuable upon exercise of such Warrant  immediately  prior to such
reclassification,  change,  consolidation,  merger, sale or conveyance and enter
into a  supplemental  warrant  agreement so  providing.  Such  provisions  shall
include  provision for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 10. If the issuer of
securities  deliverable upon exercise of Warrants under the supplemental warrant
agreement is an Affiliate of the formed,  surviving or  transferee  corporation,
that  issuer  shall  join  in the  supplemental  warrant  agreement.  The  above
provisions  of  this   paragraph  (b)  shall   similarly   apply  to  successive
reclassifications  and  changes  of  shares of  Common  Stock and to  successive
consolidations,  mergers,  sales or conveyances.  (c) Distribution of Options or
Convertible  Securities.  In the event that both (x) the Company  shall,  at any
time or from time to time after the date  hereof,  issue,  sell,  distribute  or
otherwise  grant in any manner  (including by  assumption) to all holders of the
Common  Stock any rights to  subscribe  for or to  purchase,  or any warrants or
options for the purchase of, Common Stock or any stock or securities convertible
into or  exchangeable  for Common  Stock (any such  rights,  warrants or options
being herein called "Options" and any such convertible or exchangeable  stock or
securities  being herein called  "Convertible  Securities")  or any  Convertible
Securities  (other than upon exercise of any Option and other than a dividend or
distribution subject to paragraph (a) above), whether or not such Options or the
rights to  convert or  exchange  such  Convertible  Securities  are  immediately
exercisable,  and (y) the price per share at which Common Stock is issuable upon
the  exercise  of such  Options  or upon  the  conversion  or  exchange  of such
Convertible Securities (determined by dividing (i) the aggregate amount, if any,
received or receivable by the Company as consideration  for the issuance,  sale,
distribution or granting of such Options or any such Convertible Security,  plus
the minimum aggregate amount (determined without regard to possible  adjustments
that are  contingent  upon future events) of additional  consideration,  if any,
payable to the Company upon the exercise of all such Options or upon  conversion
or exchange of all such Convertible Securities,  plus, in the case of Options to
acquire  Convertible  Securities,  the minimum  aggregate  amount of  additional
consideration,  if any,  payable  upon the  conversion  or  exchange of all such
Convertible  Securities,  by (ii) the total maximum number of shares (determined
without regard to possible  adjustments  that are contingent upon future events)
of Common  Stock  issuable  upon the  exercise  of all such  Options or upon the
conversion or exchange of all such Convertible Securities or upon the conversion

<PAGE>


or exchange of all Convertible Securities issuable upon the exercise of all such
Options)  shall be less than the Current  Market Price per share of Common Stock
on the record  date for the  issuance,  sale,  distribution  or granting of such
Options  or  Convertible  Securities  (any  such  event  being  herein  called a
"Distribution"),  then, effective upon such Distribution, (I) the Exercise Price
shall be reduced to the price  (calculated  to the nearest  1/1,000 of one cent)
determined by multiplying the Exercise Price in effect immediately prior to such
Distribution  by a fraction,  the numerator of which shall be the sum of (1) the
number of shares of Common Stock outstanding  (exclusive of any treasury shares)
immediately  prior to such  Distribution  multiplied by the Current Market Price
per  share  of  Common  Stock  on the  date of such  Distribution  plus  (2) the
consideration,  if any, received by the Company upon such Distribution,  and the
denominator  of which shall be the product of (A) the total  number of shares of
Common Stock  outstanding  (exclusive of any treasury shares)  immediately after
such Distribution multiplied by (B) the Current Market Price per share of Common
Stock on the record date for such  Distribution and (II) the number of shares of
Common Stock purchasable upon the exercise of each Warrant shall be increased to
a number  determined  by  multiplying  the  number of shares of Common  Stock so
purchasable  immediately  prior to the record  date for such  Distribution  by a
fraction,  the  numerator  of  which  shall  be the  Exercise  Price  in  effect
immediately prior to the adjustment  required by clause (I) of this sentence and
the denominator of which shall be the Exercise Price in effect immediately after
such  adjustment  (for the purposes of this clause (ii) without giving effect to
the  provisions  of Section  10(i)).  For purposes of the  foregoing,  the total
maximum  number of shares of Common  Stock  issuable  upon  exercise of all such
Options or upon  conversion  or exchange of all such  Convertible  Securities or
upon the conversion or exchange of the total maximum  amount of the  Convertible
Securities  issuable  upon the exercise of all such  Options  shall be deemed to
have been issued as of the date of such  Distribution  and  thereafter  shall be
deemed to be  outstanding  and the Company  shall be deemed to have  received as
consideration therefor such price per share, determined as provided above, which
shall constitute  consideration  received by the Company upon such  Distribution
for purposes of the foregoing calculations.  For purposes of the foregoing,  the
total number of shares of Common Stock  issuable  upon exercise or conversion of
outstanding Options or Convertible Securities shall be deemed outstanding before
and after such  Distribution  if the exercise or  conversion  price with respect
thereto is less than the Current  Market  Value.  No adjustment to the number of
Warrant  Shares  issuable  upon the  exercise of the Warrants or to the Exercise
Price  shall be made,  however,  as a result  of (i) the  issuance  of shares of
Common  Stock under any Options  existing on the date hereof or issued  pursuant
hereto,  (ii) the  issuance  of shares of  Common  Stock in bona fide  public or
private  offerings  that  are  underwritten  or in  which a  placement  agent is
retained  by the  Company or (iii) the  issuance  of Options or shares of Common
Stock pursuant to any Option,  under any employee  benefit plans approved by the
Board of Directors. Such adjustments shall be made whenever such rights, options
or  warrants  or  convertible  securities  are  issued.  Except as  provided  in
paragraphs  (k) and (l) below,  no additional  adjustment of the Exercise  Price
shall be made upon the actual  exercise of such  Options or upon  conversion  or
exchange of the Convertible Securities or upon the conversion or exchange of the
Convertible  Securities  issuable upon the exercise of such  Options.  (d) Other
Issuances of Common Stock, Options or Convertible Securities.  Upon any issuance
of Common Stock,  Options or Convertible  Securities as to which paragraphs (a),
(b) and (c) above are not applicable, in the event that at any time or from time
to time the  Company  shall  issue (i) shares of Common  Stock  (subject  to the
provisions below), (ii) Options (provided,  however, that no adjustment shall be
made  upon  the  exercise  of such  Options)  or  (iii)  Convertible  Securities
(provided,  however,  that no  adjustment  shall be made  upon  the  conversion,
exchange or exercise of such securities (other than issuances  specified in (i),
(ii) or (iii) which are made as the result of  antidilution  adjustments in such
securities)),  at a price  per share  (determined,  in the case of  Options  and
Convertible Securities, as provided in clause (y) of paragraph (c) above) at the
record date of such issuance that is less than the then Current Market Price per
share of Common Stock,  then the number of shares of Common Stock  issuable upon
the  exercise of each  Warrant  shall be  increased  to a number  determined  by
multiplying  the  number of shares of Common  Stock  theretofore  issuable  upon
exercise of each  Warrant by a  fraction,  the  numerator  of which shall be the
number of shares of Common  Stock  outstanding  immediately  after  such sale or
issuance  (including  shares  deemed  outstanding  as provided in paragraph  (c)
above) plus the number of  additional  shares of Common  Stock into or for which
such  securities that are issued are  convertible,  exchangeable or exercisable,
and the  denominator  of which  shall be the  number of  shares of Common  Stock
outstanding  immediately prior to such sale or issuance (including shares deemed
outstanding  as provided in paragraph (c) above) plus the total number of shares
of Common Stock which the aggregate consideration expected to be received by the
Company  (assuming the exercise or conversion of all such Options or Convertible
Securities, if any) would purchase at the then Current Market Price per share of
Common Stock,  and subject to paragraph (i) below,  the Exercise  Price shall be
adjusted to a number determined by dividing the Exercise Price immediately prior
to such date of issuance by the aforementioned fraction; provided, however, that
no adjustment to the number of Warrant Shares  issuable upon the exercise of the
Warrants or to the Exercise  Price shall be made as a result of (i) the issuance
of shares of Common Stock under any Options or Convertible  Securities  existing
on the date hereof or issued  pursuant  hereto,  (ii) the  issuance of shares of
Common Stock and/or Options and/or Convertible Securities in bona fide public or
private  offerings  that  are  underwritten  or in  which a  placement  agent is
retained  by the  Company or (iii) the  issuance  of Options or shares of Common
Stock pursuant to any Option,  under any employee  benefit plans approved by the
Board of Directors. Such adjustments shall be made whenever such rights, options
or warrants or convertible  securities are issued.  No adjustment  shall be made
pursuant to this  paragraph  (d) which shall have the effect of  decreasing  the
number of shares of Common Stock  issuable  upon  exercise of each warrant or of
increasing the Exercise Price,  except by operation of paragraph (k) below.  For

<PAGE>

purposes of paragraph (c) hereof and this  paragraph  (d) only,  any issuance of
Common Stock, Options or Convertible Securities, which issuance (or agreement to
issue) (A) is in exchange  for or  otherwise  in  connection  with the bona fide
acquisition  of  property  or assets of any kind  (excluding  any such  exchange
exclusively  for cash) of any Person and (B) is at a price per share  determined
by the Board of Directors  to be equal to the fair market  value  thereof at the
time an agreement in principle is reached or at the time a definitive  agreement
is entered into, shall be deemed to have been made at a price per share equal to
the  Current  Market  Price per share at the  record  date with  respect to such
issuance (the time of closing or  consummation  of such exchange or acquisition)
if such definitive  agreement is entered into within 90 days of the date of such
agreement in  principle.  (e)  Combination;  Liquidation.  In the event of (A) a
combination  where  consideration to the holders of Common Stock in exchange for
their shares is payable  solely in cash or (B) the  dissolution,  liquidation or
winding-up of the Company,  Holders shall be entitled to receive, upon surrender
of their Warrant Certificates,  distributions on an equal basis with the holders
of Common Stock or other securities,  issuable upon exercise of the Warrants, as
if the Warrants had been  exercised  immediately  prior to such event,  less the
Exercise Price.  Upon receipt of such payment,  if any, the Warrants will expire
and the rights of the Holders will cease. In case of any  combination  described
in this  paragraph  (e), the surviving or acquiring  Person and, in the event of
any  dissolution,  liquidation  or winding-up of the Company,  the Company shall
deposit  promptly with the Warrant Agent the funds, if any,  necessary to pay to
the holders of the Warrant the amounts to which they are  entitled as  described
above. After such funds and the surrendered  Warrant  Certificates are received,
the  Warrant  Agent  is  required  to  deliver  a  check  in such  amount  as is
appropriate,  as  instructed  by the Company  (or, in the case of  consideration
other than cash, such other consideration as is appropriate),  to such Person or
Persons  as it may be  directed  in  writing by the  Holders  surrendering  such
Warrants.  (f) Dividends and  Distributions.  In the event the Company shall, at
any time or from time to time  after  the date  thereof,  distribute  to all the
holders of Common Stock any dividend or other distribution of cash, evidences of
its  indebtedness,  other securities or other properties or assets (in each case
other  than (i)  dividends  payable  in Common  Stock,  Options  or  Convertible
Securities or rights to acquire the same and (ii) any cash dividend  that,  when
added to all other  cash  dividends  paid in the same  fiscal  year prior to the
declaration date of such dividend (excluding any such other dividend included in
a previous  adjustment of the Exercise Price  pursuant to this  paragraph  (f)),
does not exceed the greater of (x) the Company's retained earnings as of the end
of the prior fiscal year and (y) the Company's net earnings for the prior fiscal
year on such  declaration  date),  or any  options,  warrants or other rights to
subscribe  for or purchase any of the  foregoing,  then (A) the  Exercise  Price
shall be decreased to a price  determined by multiplying the Exercise Price then
in effect by a fraction,  the  numerator  of which  shall be the Current  Market
Price per share of Common  Stock on the record date for such  distribution  less
the sum of (X) the cash  portion,  if any,  of such  distribution  per  share of
Common Stock  outstanding  (exclusive of any treasury shares) on the record date
for such distribution plus (Y) the then fair market value (as determined in good
faith by the Board of  Directors  of the  Company)  per  share of  Common  Stock
outstanding  (exclusive  of any  treasury  shares) on the  record  date for such
distribution  of that  portion,  if  any,  of such  distribution  consisting  of
evidences  of  indebtedness,  other  securities,  properties,  assets,  options,
warrants or subscription or purchase rights,  and the denominator of which shall
be such  Current  Market  Price per share of Common  Stock and (B) the number of
shares of Common Stock  purchasable  upon the exercise of each Warrant  shall be
increased to a number  determined by multiplying  the number of shares of Common
Stock so purchasable  immediately prior to the record date for such distribution
by a fraction,  the  numerator  of which shall be the  Exercise  Price in effect
immediately prior to the adjustment  required by clause (A) of this sentence and
the denominator of which shall be the Exercise Price in effect immediately after
such  adjustment  (for the purposes of this clause (B) without  giving effect to
the provisions of Section 10(i)). The adjustments required by this paragraph (f)
shall be made whenever any such  distribution  occurs  retroactive to the record
date  for  the   determination   of   stockholders   entitled  to  receive  such
distribution.  (g) Certain  Distributions.  If the Company  shall pay a dividend
payable in  Options or  Convertible  Securities  or make any other  distribution
payable in Options or  Convertible  Securities,  then, for purposes of paragraph
(c) above,  such Options or Convertible  Securities shall be deemed to have been
issued or sold without consideration.  (h) Consideration Received. If any shares
of Common Stock,  Options or  Convertible  Securities  shall be issued,  sold or
distributed for  consideration  other than cash, the amount of the consideration
other than cash received by the Company in respect thereof shall be deemed to be
the then fair market value of such consideration (as determined in good faith by
the  Board of  Directors  of the  Company).  If any  Options  shall be issued in
connection  with  the  issuance  and sale of other  securities  of the  Company,
together comprising one integral transaction in which no specific  consideration
is  allocated  to such Options by the parties  thereto,  such  Options  shall be
deemed to have been  issued for such  consideration  as is  established  in good
faith by the  Board  of  Directors  of the  Company.  (i)  Deferral  of  Certain
Adjustments.  No  adjustment  to  the  Exercise  Price  (including  the  related
adjustment to the number of shares of Common Stock purchasable upon the exercise
of each Warrant) shall be required  hereunder unless such  adjustment,  together
with other  adjustments  carried forward as provided  below,  would result in an
increase or decrease of at least one  percent of the  Exercise  Price;  provided
that any  adjustments  which by reason of this paragraph (i) are not required to
be made  shall be carried  forward  and taken  into  account  in any  subsequent
adjustment.  No  adjustment  need be made for a change  in the par  value of the
Common Stock. All  calculations  under this Section shall be made to the nearest
1/1,000 of one cent or to the  nearest  1/1,000 of a share,  as the case may be.
(j)  Changes  in Options  and  Convertible  Securities.  If the  exercise  price
provided for in any Options  referred to in  paragraphs  (c) and (d) above,  the
additional consideration, if any, payable upon the conversion or exchange of any
Convertible  Securities referred to in paragraphs (c) and (d) above, or the rate

<PAGE>

at which any Convertible  Securities referred to in paragraphs (c) and (d) above
are convertible  into or exchangeable  for Common Stock shall change at any time
(other  than  under or by reason  of  provisions  designed  to  protect  against
dilution  upon an event which results in a related  adjustment  pursuant to this
Section  10),  the  Exercise  Price  then in effect  and the number of shares of
Common Stock  purchasable  upon the exercise of each Warrant shall  forthwith be
readjusted  (effective  only with respect to any  exercise of any Warrant  after
such readjustment) to the Exercise Price and number of shares of Common Stock so
purchasable  that  would  then be in  effect  had the  adjustment  made upon the
issuance,  sale,  distribution  or  granting  of  such  Options  or  Convertible
Securities  been  made  based  upon  such  changed  purchase  price,  additional
consideration  or conversion  rate, as the case may be, but only with respect to
such  Options  and  Convertible  Securities  as  then  remain  outstanding.  (k)
Expiration  of Options  and  Convertible  Securities.  If, at any time after any
adjustment to the number of shares of Common Stock purchasable upon the exercise
of each Warrant shall have been made pursuant to paragraph (c), (d) or (j) above
or  this  paragraph  (k),  any  Options  or  conversion  rights  of  Convertible
Securities shall have expired unexercised, the number of such shares purchasable
upon the exercise of each Warrant shall, upon such expiration, be readjusted and
shall  thereafter  be such as they  would  have  been had they  been  originally
adjusted (or had the original adjustment not been required,  as the case may be)
as if (i) the only  shares  of  Common  Stock  deemed  to have  been  issued  in
connection with such Options or Convertible Securities were the shares of Common
Stock,  if any,  actually  issued or sold upon the  exercise of such  Options or
Convertible Securities and (ii) such shares of Common Stock, if any, were issued
or sold  for the  consideration  actually  received  by the  Company  upon  such
exercise  plus the aggregate  consideration,  if any,  actually  received by the
Company for the issuance,  sale, distribution or granting of all such Options or
Convertible  Securities,  whether  or  not  exercised;  provided  that  no  such
readjustment  shall have the effect of  decreasing  the number of such shares so
purchasable  by an amount  (calculated by adjusting such decrease to account for
all other adjustments made pursuant to this Section 10 following the date of the
original adjustment referred to above) in excess of the amount of the adjustment
initially  made in respect of the issuance,  sale,  distribution  or granting of
such Options or Convertible Securities.  (l) Other Adjustments.  The Company may
at any time reduce the Exercise  Price for any period of time (but not less than
20  Business  Days) when deemed  appropriate  by the Board of  Directors  of the
Company,  provided that the Exercise  Price may not be reduced to an amount that
is less than the par value of the Common  Stock.  In the event that at any time,
as a result of an adjustment  made pursuant to any provision of this Section 10,
the Holders shall become entitled to receive any securities of the Company other
than shares of Common Stock,  thereafter the number of such other  securities so
receivable  upon exercise of the Warrants and the Exercise  Price  applicable to
such exercise  shall be subject to adjustment  from time to time in a manner and
on terms as nearly  equivalent as practicable to the provisions  with respect to
the shares of Common Stock  contained in this Section 10. SECTION 11.  Statement
on  Warrants.  Irrespective  of any  adjustment  in the number or kind of shares
issuable upon the exercise of the Warrants,  Warrants  theretofore or thereafter
issued may  continue  to express the same price and number and kind of shares as
are stated in the Warrants initially issuable pursuant to this Agreement.

SECTION 12. No Dilution or Impairment;  Capital and Ownership Structure.  If any
event  shall  occur as to which the  provisions  of Section 10 are not  strictly
applicable but the failure to make any  adjustment  would  adversely  affect the
purchase  rights  represented  by  the  Warrants  so as to be  contrary  to  the
essential  intent and  principles of such Section,  then, in each such case, the
Company shall appoint an investment banking firm of recognized national standing
that does not have a direct  or  material  indirect  financial  interest  in the
Company or any of its  subsidiaries,  who has not been,  and,  at the time it is
called upon to give  independent  financial  advice to the Company,  is not (and
none of its directors,  officers,  employees,  affiliates or stockholders are) a
promoter,  director or officer of the Company or any of its subsidiaries,  which
shall give their opinion upon the adjustment, if any, on a basis consistent with
the essential  intent and  principles  established  in Section 10,  necessary to
preserve,  on a basis  consistent  with  the  essential  intent  and  principles
established in Section 10, the purchase rights represented by the Warrants. Upon
receipt of such  opinion,  the Company will  promptly mail a copy thereof to the
holders of the Warrants and shall make the adjustments described therein.
                  The  Company  will not, by  amendment  of its  certificate  of
incorporation or through any consolidation, merger, reorganization,  transfer of
assets, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or performance of any of the terms of the
Warrants,  but will at all times in good faith assist in the carrying out of all
such  terms  and in the  taking  of  all  such  action  as may be  necessary  or
appropriate in order to protect the rights of the holder of the Warrants against
dilution or other impairment.  Without limiting the generality of the foregoing,
the Company (a) will take all such action as may be necessary or  appropriate in
order  that  the  Company   may  validly  and  legally   issue  fully  paid  and
nonassessable  shares of Common Stock on the exercise of the Warrants  from time
to time  outstanding  and (b)  will not take any  action  which  results  in any
adjustment of the Exercise Price if the total number of Warrant Shares  issuable
after the action upon the exercise of all of the Warrants would exceed the total
number of shares of Common Stock then authorized by the Company's certificate of
incorporation  and  available  for the purposes of issue upon such  exercise.  A
consolidation,  merger,  reorganization  or  transfer  of assets  involving  the
Company covered by Sections 10(b) or 10(e) shall not be prohibited by or require
any adjustment under this Section 12.

                  It is the intent of this  Agreement to provide that, on and as
of the Closing  Date,  the number of Warrant  Shares into which the Warrants are
exercisable represent approximately 8.7% of the issued and outstanding shares of
Common Stock as adjusted  pro forma on a fully  diluted  basis.  For purposes of
this paragraph,  the phrase "on a fully diluted basis" shall include any and all

<PAGE>

options,  warrants  or other  rights to  acquire  Common  Stock of the  Company,
whether or not  exercisable  on the Closing Date but excluding all such options,
warrants (other than the Warrants) or other rights to acquire Common Stock at an
exercise or conversion  price greater than the exercise price of the Warrants as
of the Closing Date, as adjusted.  If, after the Closing Date the exercise price
of the Company's then outstanding warrants, options or convertible securities is
reduced to an  exercise  price equal to or less than the  Exercise  Price of the
Warrants (as it may be adjusted as a result of the same event or  circumstance),
then the shares of Common Stock issuable upon the exercise or conversion of such
warrants,  options  or  convertible  securities,  as the  case  may be,  will be
included in the  calculation of the Common Stock on a fully-diluted  basis,  and
the  number  of  Warrant   Shares   issuable   upon  exercise  of  each  Warrant
automatically  shall be adjusted upward by multiplying such number by a fraction
, the  numerator  of  which  shall be the  number  of  shares  of  Common  Stock
outstanding on a  fully-diluted  basis after such inclusion and the numerator of
which  shall  be  the  number  of  shares  of  Common  Stock  outstanding  on  a
fully-diluted  basis  prior  to  such  inclusion;  provided,  however,  that  no
adjustment shall be made pursuant to this sentence as a result of the completion
of the exchange of the Company' s 7% Convertible Subordinated Notes due 2005.

SECTION 13.  Fractional  Interest.  The  Company  shall not be required to issue
fractional shares of Common Stock on the exercise of Warrants.  If more than one
Warrant  shall be  presented  for  exercise in full at the same time by the same
Holder,  the number of full shares of Common Stock which shall be issuable  upon
such exercise  shall be computed on the basis of the aggregate  number of shares
of Common  Stock  acquirable  on exercise of the Warrants so  presented.  If any
fraction of a share of Common Stock  would,  except for the  provisions  of this
Section,  be issuable on the  exercise  of any  Warrant  (or  specified  portion
thereof),  the Company shall direct the Transfer  Agent to pay an amount in cash
calculated by it to equal the then Current Market Price per share  multiplied by
such  fraction  computed  to the  nearest  whole cent less such  fraction of the
Exercise Price. The Holders,  by their  acceptance of the Warrant  Certificates,
expressly  waive any and all rights to receive any fraction of a share of Common
Stock or a stock certificate representing a fraction of a share of Common Stock.

SECTION 14.  Notices to Warrant  Holders;  No Rights as  Shareholders.  Upon any
adjustment  of the  Exercise  Price  pursuant  to Sections 10 or 12, the Company
shall  promptly  thereafter  (i)  cause to be filed  with  the  Warrant  Agent a
certificate of a firm of independent public accountants of nationally recognized
standing  selected  by the Board of  Directors  of the  Company  (who may be the
regular  auditors of the Company)  setting  forth the Exercise  Price after such
adjustment and setting forth in reasonable  detail the method of calculation and
the facts upon which such calculations are based and setting forth the number of
Warrant  Shares (or  portion  thereof)  issuable  after such  adjustment  in the
Exercise Price,  upon exercise of a Warrant and payment of the adjusted Exercise
Price, which certificate shall be conclusive  evidence of the correctness of the
matters set forth therein,  and (ii) cause to be given to each of the registered
Holders of the Warrant  Certificates or the DTC  Participants  with interests in
the Global Warrant at his/her address  appearing on the Warrant register written
notice of such adjustments by first-class  mail,  postage  prepaid.  The Warrant
Agent shall be entitled to rely on the above-referenced accountant's certificate
and  shall  be  under  no  duty  or  responsibility  with  respect  to any  such
certificate, except to exhibit the same from time to time to any Holder desiring
an inspection thereof during reasonable  business hours. The Warrant Agent shall
not at any time be under any duty or  responsibility  to any Holder to determine
whether any facts exist that may require any  adjustment of the number of shares
of Common Stock or other stock or property  issuable on exercise of the Warrants
or the  Exercise  Price,  or with  respect  to the  nature or extent of any such
adjustment  when made,  or with  respect to the method  employed  in making such
adjustment  or the  validity  or value (or the kind or  amount) of any shares of
Common Stock or other stock or property which may be issuable on exercise of the
Warrants.  The  Warrant  Agent shall not be  responsible  for any failure of the
Company to make any cash payment or to issue,  transfer or deliver any shares of
Common Stock or stock  certificates  or other common stock or property  upon the
exercise of any Warrant.
                  In case:

                  (a) the Company shall authorize the issuance to all holders of
         shares of Common Stock of rights,  options or warrants to subscribe for
         or purchase shares of Common Stock or of any other subscription  rights
         or warrants; or

                  (b)  the  Company  shall  authorize  the  distribution  to all
         holders of shares of Common Stock of evidences of its  indebtedness  or
         assets (other than cash dividends or cash distributions  payable out of
         consolidated  earnings or earned surplus or dividends payable in shares
         of Common Stock or distributions referred to in Section 10 hereof); or

                  (c) of any  consolidation  or merger to which the Company is a
         party and for which  approval  of any  shareholders  of the  Company is
         required, or of the conveyance or transfer of the properties and assets
         of the Company substantially as an entirety, or of any reclassification
         or change of Common Stock issuable upon exercise of the Warrants (other
         than a change in par value,  or from par value to no par value, or from
         no  par  value  to  par  value,  or as a  result  of a  subdivision  or
         combination),  or a tender offer or exchange offer for shares of Common
         Stock; or

                  (d)       of  the  voluntary  or  involuntary  dissolution,  
         liquidation  or  winding  up of  the Company; or

                  (e) the Company  proposes to take any other  action that would
         require an  adjustment  of the Exercise  Price or the number of Warrant
         Shares pursuant to Sections 10 or 12;

<PAGE>


then the Company  shall cause to be filed with the Warrant Agent and shall cause
to be given to each of the  registered  Holders of the Warrant  Certificates  at
such Holder's address appearing on the Warrant register, at least 20 days (or 10
days in any case  specified in clauses (a) or (b) above) prior to the applicable
record date hereinafter  specified,  or promptly in the case of events for which
there is no record date, by first class mail,  postage prepaid, a written notice
stating (i) the date as of which the holders of record of shares of Common Stock
to be entitled to receive any such rights, options, warrants or distribution are
to be determined,  or (ii) the initial  expiration  date set forth in any tender
offer or exchange  offer for shares of Common Stock,  or (iii) the date on which
any such consolidation,  merger, conveyance, transfer, dissolution,  liquidation
or winding up or Change of Control (as defined in the  Indenture) is expected to
become  effective or  consummated,  and the date as of which it is expected that
holders of record of shares of Common  Stock shall be entitled to exchange  such
shares  for  securities  or  other  property,  if  any,  deliverable  upon  such
reclassification,  consolidation,  merger,  conveyance,  transfer,  dissolution,
liquidation  or winding up or Change of Control.  The failure to give the notice
required by this Section 14 or any defect  therein shall not affect the legality
or validity of any distribution, right, option, warrant, consolidation,  merger,
conveyance,  transfer,  dissolution,  liquidation  or  winding  up, or Change of
Control or the vote upon any action.

                  Nothing  contained in this  Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the Holders thereof the right
to vote or to  consent or to receive  notice as  shareholders  in respect of the
meetings of  shareholders  or the  election of  Directors  of the Company or any
other matter, or any rights whatsoever as shareholders of the Company.

SECTION  15.  Merger,  Consolidation  or Change of Name of  Warrant  Agent.  Any
corporation  into which the Warrant  Agent may be merged or with which it may be
consolidated,  or any corporation  resulting from any merger or consolidation to
which the Warrant Agent shall be a party, or any  corporation  succeeding to the
business of the  Warrant  Agent,  shall be the  successor  to the Warrant  Agent
hereunder without the execution or filing of any paper or any further act on the
part of any of the  parties  hereto,  provided  that such  corporation  would be
eligible for  appointment  as a successor  warrant agent under the provisions of
Section 17. Any such successor  Warrant Agent shall promptly cause notice of its
succession as Warrant Agent to be mailed (by first class mail,  postage prepaid)
to each Holder at such Holder's last address as shown on the register maintained
by the  Warrant  Agent  pursuant  to this  Agreement.  In case at the time  such
successor  to the  Warrant  Agent  shall  succeed to the agency  created by this
Agreement,  and in case at that time any of the Warrant  Certificates shall have
been  countersigned  but not delivered,  any such successor to the Warrant Agent
may adopt the  countersignature  of the original  Warrant Agent;  and in case at
that time any of the Warrant Certificates shall not have been countersigned, any
successor to the Warrant Agent may countersign such Warrant  Certificates either
in the name of the predecessor  Warrant Agent or in the name of the successor to
the Warrant Agent;  and in all such cases such Warrant  Certificates  shall have
the full force and  effect  provided  in the  Warrant  Certificates  and in this
Agreement.

                  In case at any  time the name of the  Warrant  Agent  shall be
changed  and at such  time  any of the  Warrant  Certificates  shall  have  been
countersigned  but not delivered,  the Warrant Agent whose name has been changed
may adopt the  countersignature  under its prior name,  and in case at that time
any of the Warrant  Certificates shall not have been countersigned,  the Warrant
Agent may countersign such Warrant  Certificates  either in its prior name or in
its changed name, and in all such cases such Warrant Certificates shall have the
full  force  and  effect  provided  in the  Warrant  Certificates  and  in  this
Agreement.

SECTION  16.  Warrant  Agent.  The  Warrant  Agent  undertakes  the  duties  and
obligations  imposed by this Agreement upon the following  terms and conditions,
by all of which the  Company and the Holders of  Warrants,  by their  acceptance
thereof, shall be bound:

                  (a)  The  statements  contained  herein  and  in  the  Warrant
Certificates  shall be taken as  statements of the Company and the Warrant Agent
assumes no responsibility  for the correctness of any of the same except such as
describe  the  Warrant  Agent or action  taken or to be taken by it. The Warrant
Agent assumes no responsibility  with respect to the distribution of the Warrant
Certificates  except  as  otherwise  provided  by  the  express  terms  of  this
Agreement.

                  (b) The Warrant Agent shall not be responsible for any failure
of the Company to comply with any of the covenants  contained in this  Agreement
or in the Warrant Certificates to be complied with by the Company.

                  (c) The Warrant  Agent may consult at any time with counsel of
its own  selection  (who may be counsel for the Company)  and the Warrant  Agent
shall incur no  liability or  responsibility  to the Company or to any Holder of
any Warrant  Certificate in respect of any action taken,  suffered or omitted by
it hereunder in good faith and in  accordance  with the opinion or the advice of
such counsel.

<PAGE>


                  (d) Before the Warrant Agent acts or refrains from acting,  it
may require an  officer's  certificate  or an opinion of counsel,  or both.  The
Warrant   Agent  may   conclusively   rely  and  shall  incur  no  liability  or
responsibility  to the Company or to any Holder of any Warrant  Certificate  for
any action taken in reliance on any Warrant Certificate,  certificate of shares,
notice,  resolution,  waiver,  consent,  order,  certificate,  or  other  paper,
document or instrument  (whether in its original or facsimile  form) believed by
it to be genuine and to have been signed,  sent or presented by the proper party
or parties.

                  (e)  The  Company  agrees  to pay to the  Warrant  Agent  such
compensation  as shall be  agreed  upon  from  time to time in  writing  for all
services  rendered by the Warrant Agent in the execution of this  Agreement,  to
reimburse the Warrant Agent for all expenses, taxes and governmental charges and
other charges of any kind and nature reasonably incurred by the Warrant Agent in
the  execution  of this  Agreement  and to indemnify  the Warrant  Agent and any
predecessor  Warrant Agent and save it harmless against any and all liabilities,
claims,  damages, losses and expenses (including taxes other than taxes based on
the income of the  Warrant  Agent)  including  judgments,  reasonable  costs and
counsel fees and expenses,  for anything done or omitted by the Warrant Agent in
the  execution  of this  Agreement or arising out of or in  connection  with its
performance  of its  obligations or duties under this  Agreement,  except to the
extent such  liabilities  are  attributable  to its gross  negligence or willful
misconduct. The Warrant Agent shall notify the Company promptly of any claim for
which it may seek  indemnity;  provided that the failure by the Warrant Agent to
so notify the Company shall not relieve its obligations  hereunder.  The Company
shall defend the claim and the Warrant Agent shall cooperate in the defense. The
Warrant Agent may have separate counsel and the Company shall pay the reasonable
fees and expenses of such counsel.  The Company need not pay for any  settlement
made without its consent, which consent shall not be unreasonably withheld.

                  (f)  The  Warrant  Agent  shall  be  under  no  obligation  to
institute  any  action,  suit or legal  proceeding  or to take any other  action
likely to involve  expense  unless the Company or one or more Holders of Warrant
Certificates  shall  furnish  the  Warrant  Agent with  security  and  indemnity
reasonably  satisfactory to it for any costs and expenses which may be incurred,
but this provision  shall not affect the power of the Warrant Agent to take such
action as is necessary,  whether with or without any such security or indemnity.
All rights of action  under this  Agreement  or under any of the Warrants may be
enforced  by the Warrant  Agent  without  the  possession  of any of the Warrant
Certificates or the production thereof at any trial or other proceeding relative
thereto, and any such action, suit or proceeding instituted by the Warrant Agent
shall be brought in its name as Warrant Agent and any recovery of judgment shall
be for the ratable benefit of the Holders of the Warrants,  as their  respective
rights or interests may appear.

                  (g) The Warrant Agent, and any stockholder,  director, officer
or  employee  of it,  may  buy,  sell or deal in any of the  Warrants  or  other
securities of the Company or become pecuniarily interested in any transaction in
which the  Company  may be  interested,  or  contract  with or lend money to the
Company or otherwise act as fully and freely as though it were not Warrant Agent
under this  Agreement.  Nothing  herein shall  preclude  the Warrant  Agent from
acting in any other capacity for the Company or for any other legal entity.

                  (h) The Warrant Agent shall act hereunder  solely as agent for
the Company, and its duties shall be determined solely by the provisions hereof.
The Warrant  Agent shall not be liable for  anything  which it may do or refrain
from doing in connection with this Agreement except for its own gross negligence
or willful misconduct.

                  (i) The Warrant  Agent shall not at any time be under any duty
or responsibility  to any Holder of any Warrant  Certificate to make or cause to
be made any  adjustment of the Exercise Price or number of the Warrant Shares or
other  securities or property  deliverable as provided in this Agreement,  or to
determine whether any facts exist which may require any of such adjustments,  or
with respect to the nature or extent of any such adjustments, when made, or with
respect to the method  employed in making the same.  The Warrant Agent shall not
be  accountable  with  respect to the validity or value or the kind or amount of
any Warrant  Shares or of any  securities  or property  which may at any time be
issued or delivered  upon the exercise of any Warrant or with respect to whether
any such Warrant Shares or other  securities  will when issued be validly issued
and fully  paid and  nonassessable,  and makes no  representation  with  respect
thereto.

                  (j) The Warrant  Agent  undertakes  to perform such duties and
only such duties as are specifically set forth in this Agreement, and no implied
covenants or obligations  shall be read into this Agreement  against the Warrant
Agent.

                  (k) The Warrant Agent may  conclusively  rely, as to the truth
of the statements and the correctness of the opinions  expressed  therein,  upon
certificates  or opinions  furnished to the Warrant Agent and  conforming to the
requirements  of this  Agreement;  but in the case of any such  certificates  or
opinions which by any provision hereof are specifically required to be furnished
to the Warrant  Agent,  the  Warrant  Agent shall be under a duty to examine the
same to  determine  whether  or not they  conform  to the  requirements  of this
Agreement  (but need not confirm or  investigate  the  accuracy of  mathematical
calculations or other facts stated therein).

                  (l) The Warrant  Agent shall not be liable with respect to any
action taken or omitted to be taken by it in good faith in  accordance  with the
direction  of the  Holders of a majority of the  Warrants  relating to the time,
method and place of conducting any  proceeding  for any remedy  available to the
Warrant  Agent,  or  exercising  any trust or power  conferred  upon the Warrant
Agent, under this Agreement with respect to the Warrants.

                  (m) No provision of this  Agreement  shall require the Warrant
Agent to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder,  or in the exercise of any of
its rights or powers,  if it shall have  reasonable  grounds for believing  that
repayment of such funds or adequate  indemnity against such risk or liability is
not reasonably assured to it.

                  (n)  Whether  or not  therein  expressly  so  provided,  every
provision of this  Agreement  relating to the conduct or affecting the liability
of or  affording  protection  to the  Warrant  Agent  shall  be  subject  to the
provisions of this Section.

                  (o)  The  Warrant  Agent  shall  not  be  bound  to  make  any
investigation  into the facts or matters stated in any resolution,  certificate,
statement,  instrument,  opinion, report, notice, request,  direction,  consent,
order, bond,  debenture,  note, other evidence of indebtedness or other paper or
document,  but the  Warrant  Agent,  in its  discretion,  may make such  further
inquiry or  investigation  into such facts or maters as it may see fit,  and, if
the Warrant Agent shall determine to make such further inquiry or investigation,
it shall be entitled to examine the books,  records and premises of the Company,
personally  or by agent or  attorney  at the sole cost of the  Company and shall
incur no  liability  or  additional  liability of any kind by any reason of such
inquiry or investigation.

                  (p) The Warrant  Agent may execute any of the trusts or powers
hereunder  or perform  any duties  hereunder  either  directly  or by or through
agents or  attorneys  and the  Warrant  Agent shall not be  responsible  for any
willful  misconduct  or gross  negligence  on the part of any agent or  attorney
appointed with due care by it hereunder.

                  (q) The  Warrant  Agent  shall  not be liable  for any  action
taken,  suffered  or  omitted  to be taken by it in good  faith  and  reasonably
believed by it to be  authorized  or within the  discretion  or rights or powers
conferred upon it by this Agreement.

                  (r) The  Warrant  Agent  shall not be deemed to have notice of
any  Default or Event of Default  unless a  Responsible  Officer of the  Warrant
Agent has actual  knowledge  thereof or unless written notice of any event which
is in fact such a default is received by the Warrant  Agent at the office of the
Warrant Agent, and such notice references the Securities and this Agreement.

                  (s)  The  rights,  privileges,   protections,  immunities  and
benefits given to the Warrant Agent, including, without limitation, its right to
be indemnified,  are extended to, and shall be enforceable by, the Warrant Agent
in each of its  capacities  hereunder,  and to each agent,  custodian  and other
Person employed to act hereunder.

SECTION 17. Resignation and Removal of Warrant Agent;  Appointment of Successor.
No resignation or removal of the Warrant Agent and no appointment of a successor
warrant agent shall become  effective until the acceptance of appointment by the
successor  warrant  agent as provided  herein.  The Warrant Agent may resign its
duties and be discharged from all further duties and liability hereunder (except
liability  arising as a result of the Warrant  Agent's own gross  negligence  or
willful misconduct) after giving written notice to the Company.  The Company may
remove the  Warrant  Agent upon  written  notice,  and the  Warrant  Agent shall
thereupon in like manner be discharged  from all further duties and  liabilities
hereunder,  except as  aforesaid.  The Warrant  Agent  shall,  at the  Company's
expense,  cause to be mailed (by first  class  mail,  postage  prepaid)  to each
Holder of a Warrant at his last  address as shown on the register of the Company
maintained  by the Warrant  Registrar a copy of said  notice of  resignation  or
notice of removal,  as the case may be. Upon such  resignation  or removal,  the
Company shall appoint in writing a new warrant agent.  If the Company shall fail
to make such  appointment  within a period of 30 days after it has been notified
in writing of such  resignation  by the  resigning  Warrant  Agent or after such
removal,  then the  resigning  Warrant Agent or the Holder of any Warrant may at
the expense of the Company apply to any court of competent  jurisdiction for the
appointment of a new warrant agent. Any new warrant agent,  whether appointed by
the Company or by such a court,  shall be a corporation doing business under the
laws of the United  States or any state  thereof,  in good standing and having a
combined capital and surplus of not less than $50,000,000.  The combined capital
and  surplus of any such new warrant  agent  shall be deemed to be the  combined
capital  and  surplus  as set  forth in the most  recent  annual  report  of its
condition  published by such warrant  agent prior to its  appointment,  provided
that such  reports are  published  at least  annually  pursuant to law or to the
requirements  of a federal or state  supervising or examining  authority.  After
acceptance in writing of such  appointment by the new warrant agent, it shall be
vested with the same powers,  rights,  duties and  responsibilities as if it had
been  originally  named  herein  as  the  Warrant  Agent,  without  any  further
assurance,  conveyance, act or deed; but if for any reason it shall be necessary
or expedient to execute and deliver any further  assurance,  conveyance,  act or
deed,  the same shall be done at the expense of the Company and shall be legally
and validly  executed and delivered by the resigning or removed  Warrant  Agent.
Not later than the  effective  date of any such  appointment,  the Company shall
give notice thereof to the resigning or removed  Warrant Agent.  Failure to give
any notice provided for in this Section,  however, or any defect therein,  shall
not affect the legality or validity of the  resignation  of the Warrant Agent or
the appointment of a new warrant agent, as the case may be.

SECTION 18.  Registration.  The Company acknowledges that Holders shall have the
registration rights set forth in the Warrant  Registration  Rights Agreement,  a

report thereon by the Company's certified independent accountants;  and (ii) all
current  reports that would be required to be filed with the  Commission on Form
8-K if the Company were required to file such reports.  In addition,  whether or
not required by the rules and  regulations of the  Commission,  the Company will
file a copy of all such  information  and reports with the Commission for public
availability (unless the Commission will not accept such a filing) and make such
information  available to securities  analysts and  prospective  investors  upon
request.
                  Delivery of such  reports,  information  and  documents to the
Warrant Agent is for  informational  purposes only and the receipt of such shall
not  constitute  constructive  notice of any  information  contained  therein or
determinable  from  information  contained  therein,   including  the  Company's
compliance with any of its covenants hereunder (as to which the Warrant Agent is
entitled to rely exclusively on officers' certificates).

                  (b)  The  Company  shall  provide  the  Warrant  Agent  with a
sufficient number of copies of all reports filed with the Commission pursuant to

Securities,  to such Holder or beneficial owner of Registrable  Securities,  the

thereby  in a timely  manner  in order to  permit  resales  of such  Registrable
Securities pursuant to Rule 144.

authorized by this  Agreement to be given or made by the Warrant Agent or by the
Holder of any Warrant  Certificate  to or on the Company  shall be  sufficiently

location  thereof,  presentations  may be made and  notices  and  demands may be
served at the principal office of the Warrant Agent.

                  Any  notice  pursuant  to this  Agreement  to be  given by the
Company or by the  Holder(s)  of any Warrant  Certificate  to the Warrant  Agent

SECTION 22.  Supplements and  Amendments.  The Company and the Warrant Agent may
from time to time supplement or amend this Agreement without the approval of any
Holders of Warrant  Certificates in order to cure any ambiguity or to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provision  herein,  or to make any other  provisions in regard to
matters or questions  arising  hereunder which the Company and the Warrant Agent
may deem  necessary  or  desirable  and which  shall  not in any way  materially
adversely  affect  the  interests  of any Holder of  Warrant  Certificates.  Any
amendment or  supplement  to this  Agreement  that has an adverse  effect on the
interests of Holders shall require the written consent of Holders representing a
majority  of the  then  outstanding  Warrants  (excluding  Warrants  held by the
Company  or any of its  Affiliates).  The  consent  of each  Holder of a Warrant
affected  shall be required  for any  amendment  pursuant to which the  Exercise
Price  would be  increased  or the number of  Warrant  Shares  purchasable  upon
exercise of Warrants  would be  decreased  (other than  pursuant to  adjustments
provided by this  Agreement) or the exercise period with respect to the Warrants
would be shortened.  The Warrant Agent shall be entitled to receive and, subject
to  Section  16,  shall  be  fully  protected  in  relying  upon,  an  officers'
certificate  and  opinion  of  counsel  as  conclusive  evidence  that  any such
amendment or supplement is  authorized  or permitted  hereunder,  that it is not
inconsistent herewith, and that it will be valid and binding upon the Company in
accordance with its terms.

to Warrants previously exercised,  with respect to Section 16(e) hereof and with
respect to  indemnification  under Section 17) shall terminate at 5:00 p.m., New
York City time on the Expiration Date. SECTION 25. Governing Law. THIS AGREEMENT

                                   [Reverse]

THIS  GLOBAL  WARRANT  IS HELD BY THE  DEPOSITARY  (AS  DEFINED  IN THE  WARRANT
AGREEMENT  GOVERNING  THIS WARRANT) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF
THE BENEFICIAL  OWNERS HEREOF,  AND IS NOT  TRANSFERABLE TO ANY PERSON UNDER ANY
CIRCUMSTANCES EXCEPT THAT(I) THE WARRANT AGENT MAY MAKE SUCH NOTATIONS HEREON AS
MAY BE REQUIRED  PURSUANT TO SECTION  3.5 OF THE  WARRANT  AGREEMENT,  (II) THIS
GLOBAL WARRANT MAY BE EXCHANGED OR TRANSFERRED  PURSUANT TO SECTIONS 3.5(a), 3.6
AND 3.7 OF THE WARRANT  AGREEMENT AND (III) THIS GLOBAL WARRANT MAY BE DELIVERED
TO THE  WARRANT  AGENT FOR  CANCELLATION  PURSUANT TO SECTION 3.8 OF THE WARRANT
AGREEMENT.

UNLESS THIS  CERTIFICATE  IS PRESENTED BY AN  AUTHORIZED  REPRESENTATIVE  OF THE

TRANSFER,  EXCHANGE OR PAYMENT,  AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE
NAME OF CEDE & CO. OR TO SUCH  OTHER  ENTITY AS IS  REQUESTED  BY AN  AUTHORIZED
REPRESENTATIVE  OF THE DEPOSITORY  TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE
TO  CEDE  & CO.  OR TO  SUCH  OTHER  ENTITY  AS IS  REQUESTED  BY AN  AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY),  ANY TRANSFER,  PLEDGE OR OTHER
USE HEREOF FOR VALUE OR  OTHERWISE  BY OR TO ANY  PERSON IS  WRONGFUL  SINCE THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

THE SECURITY (OR ITS PREDECESSOR)  EVIDENCED  HEREBY WAS ORIGINALLY  ISSUED IN A
TRANSACTION  EXEMPT  FROM  REGISTRATION  UNDER  SECTION 5 OF THE  UNITED  STATES
SECURITIES  ACT OF 1933,  AS AMENDED (THE  "SECURITIES  ACT"),  AND THE SECURITY
EVIDENCED  HEREBY  MAY NOT BE  OFFERED,  SOLD OR  OTHERWISE  TRANSFERRED  IN THE

PURCHASER  OF THE  SECURITY  EVIDENCED  HEREBY  (1) BY  ITS  ACQUISITION  HEREOF
REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A
UNDER THE  SECURITIES  ACT) AND (2) IS HEREBY  NOTIFIED  THAT THE  SELLER MAY BE
RELYING ON THE EXEMPTION  FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
PROVIDED BY RULE 144A THEREUNDER OR ANOTHER  EXEMPTION UNDER THE SECURITIES ACT.
THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE ISSUER
THAT (X) SUCH  SECURITY MAY BE RESOLD,  PLEDGED OR OTHERWISE  TRANSFERRED,  ONLY
(i)(a)  TO  A  PERSON  WHOM  THE  SELLER  REASONABLY  BELIEVES  IS  A  QUALIFIED
INSTITUTIONAL  BUYER (AS  DEFINED  IN RULE 144A UNDER THE  SECURITIES  ACT) IN A
TRANSACTION  MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING
THE  REQUIREMENTS  OF RULE 144A UNDER THE  SECURITIES  ACT, OR (c) IN ACCORDANCE
WITH ANOTHER  AVAILABLE  EXEMPTION  FROM THE  REGISTRATION  REQUIREMENTS  OF THE
SECURITIES  ACT  (AND  BASED  UPON AN  OPINION  OF  COUNSEL  IF THE  COMPANY  SO
REQUESTS),  (ii) TO THE COMPANY OR (iii)  PURSUANT TO AN EFFECTIVE  REGISTRATION
STATEMENT AND, IN EACH CASE, IN ACCORDANCE  WITH ANY APPLICABLE  SECURITIES LAWS
OF ANY STATE OF THE UNITED STATES OR ANY OTHER  APPLICABLE  JURISDICTION AND (Y)
THE  HOLDER  WILL,  AND WILL  REQUIRE  EACH  SUBSEQUENT  HOLDER  TO,  NOTIFY ANY
PURCHASER FROM IT OF THE SECURITY  EVIDENCED  HEREBY OF THE RESALE  RESTRICTIONS
SET FORTH IN (X) ABOVE.

THE WARRANT AGREEMENT CONTAINS A PROVISION REQUIRING THE WARRANT AGENT TO REFUSE
TO REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING.

         Unless and until it is  exchanged  in whole or in part for  Warrants in
certificated  form, this Warrant may not be transferred except as a whole by the
depositary to a nominee of the  depositary or by a nominee of the  depositary to
the depositary or another  nominee of the depositary or by the depositary or any
such  nominee  to  a  successor  depositary  or  a  nominee  of  such  successor
depositary.  The Depository Trust Company ("DTC"),  (55 Water Street,  New York,
New York) shall act as the  Depositary  until a successor  shall be appointed by
the Company and the Warrant Agent.

         The Warrants  evidenced by this Warrant  Certificate are part of a duly
authorized  issue of Warrants  expiring  March 2, 2004  entitling  the holder on
exercise to receive shares of Common Stock, par value $0.01, of the Company (the
"Common Stock"),  and are issued or to be issued pursuant to a Warrant Agreement
dated as of March 2, 1999 (the "Warrant Agreement"), duly executed and delivered
by the  Company to IBJ  Whitehall  Bank & Trust  Company  as warrant  agent (the
"Warrant Agent"), which Warrant Agreement is hereby incorporated by reference in
and made a part of this  instrument and is hereby  referred to for a description
of  the  rights,  limitation  of  rights,  obligations,  duties  and  immunities
thereunder  of the  Warrant  Agent,  the  Company  and the  holders  (the  words
"holders" or "holder"  meaning the registered  holders or registered  holder) of
the  Warrants.  A copy of the  Warrant  Agreement  may be obtained by the holder
hereof  upon  written  request to the  Company.  Capitalized  terms used  herein
without  definition  shall have the  meanings  ascribed  to them in the  Warrant

2.                Registration Under the Securities Act.

(a) Exchange Offer Registration.  To the extent not prohibited by any applicable
law or applicable  interpretation  of the staff of the  Commission,  the Company
shall (A) file on or prior to the 180th  calendar day following the Closing Date
an Exchange Offer  Registration  Statement  covering the offer by the Company to
the Holders of Exchange  Notes with terms  identical  to the Notes  (except that
such  Exchange  Notes will not bear  legends or  contain  terms with  respect to

best efforts to cause such Exchange Offer Registration  Statement to be declared
effective by the  Commission on or prior to the 210th calendar day following the
Closing Date, (C) use its best efforts to cause such Exchange Offer Registration
Statement to remain  effective  until the closing of the Exchange  Offer and (D)
use its best efforts to consummate  the Exchange  Offer on or prior to the 240th
calendar day following the Closing Date. Upon the  effectiveness of the Exchange
Offer Registration  Statement,  the Company shall promptly commence the Exchange
Offer,  it being the  objective  of such  Exchange  Offer to enable  each Holder
(other than  Participating  Broker-Dealers  (as defined in Section  3(f) hereof)
eligible and electing to exchange Registrable Notes for Exchange Notes (assuming
that such Holder is not an affiliate  of the Company  within the meaning of Rule
405 under the Securities Act, acquires the Exchange Notes in the ordinary course
of such Holder's  business and has no  arrangements or  understandings  with any
person to participate in the Exchange Offer for the purpose of distributing  the
Exchange  Notes) to trade  such  Exchange  Notes  from and after  their  receipt
without any  limitations  or  restrictions  under the Securities Act and without
material  restrictions under the securities laws of a substantial  proportion of
the  several  states of the  United  States.  For each Note  surrendered  to the
Company pursuant to the Registered  Exchange Offer, the Holder of such Note will
receive  an  Exchange  Note  having  a  principal  amount  equal  to that of the
surrendered Note. The Exchange Notes will be issued under the Indenture.

                  In connection with the Exchange Offer, the Company shall:

(i)      mail  to  each  Holder  a copy of the  Prospectus  forming  part of the
         Exchange  Offer  Registration  Statement,  together with an appropriate
         letter of transmittal and related documents;

(ii)     keep the Exchange  Offer open for not less than 20 business  days after
         the date notice thereof is mailed to the Holders (or longer if required
         by applicable law);

(iii)    use the  services of the  Depositary  for the Exchange  Offer 
         with respect to Notes  evidenced by global certificates;

(iv) permit Holders to withdraw tendered  Registrable Notes at any time prior to
the close of business, New York City time, on the last business day on which the
Exchange Offer shall remain open, by sending to the institution specified in the
notice a telegram,  telex,  facsimile  transmission  or letter setting forth the
name of such Holder,  the principal  amount of Registrable  Notes  delivered for
exchange,  and a statement that such Holder is withdrawing  his election to have
such  Notes  exchanged;  and (v)  otherwise  comply  in all  respects  with  all
applicable laws relating to the Exchange Offer.
                  As soon as practicable  after the close of the Exchange Offer,
the Company shall:

(i)      accept for  exchange  Registrable  Notes duly  tendered and not validly
         withdrawn  pursuant to the Exchange Offer in accordance  with the terms
         of  the  Exchange  Offer  Registration  Statement  and  the  letter  of
         transmittal which is an exhibit thereto;

(ii)     deliver,  or cause to be delivered,  to the Trustee for  cancellation  
         all  Registrable  Notes so accepted for exchange by the Company; and

(iii) cause the Trustee  promptly to authenticate  and deliver Exchange Notes to
each Holder of  Registrable  Notes equal in amount to the  Registrable  Notes of
such Holder so accepted for exchange.
                  Interest on each  Exchange Note will accrue from the last date
on which  interest was paid on the  Registrable  Notes  surrendered  in exchange
therefor or, if no interest has been paid on the Registrable  Notes,  from March
2, 1999. The Exchange Offer shall not be subject to any  conditions,  other than
that the Exchange  Offer,  or the making of any  exchange by a Holder,  does not
violate  applicable  law or any  applicable  interpretation  of the staff of the
Commission.   Each  Holder  of  Registrable  Notes  (other  than   Participating
Broker-Dealers) who wishes to exchange such Registrable Notes for Exchange Notes
in the Exchange Offer shall have  represented  that (i) any Exchange Notes to be
received by it will be acquired in the ordinary course of business,  (ii) at the
time  of the  commencement  of the  Exchange  Offer  it  has no  arrangement  or
understanding  with any person to  participate in the  distribution  (within the
meaning  of the  Securities  Act)  of the  Exchange  Notes,  (iii)  it is not an
affiliate (as defined in Rule 405 under the Securities  Act) of the Company,  or
if it is an  affiliate,  it will comply  with the  registration  and  prospectus
delivery requirements of the Securities Act to the extent applicable and (iv) it
is not acting on behalf of any person who could not make the  representations in
clauses (i) through (iii). The Company shall inform the Initial Purchaser of the
names and addresses of the Holders to whom the Exchange  Offer is made,  and the
Initial  Purchaser  shall have the right to contact such  Holders and  otherwise
facilitate the tender of Registrable Notes in the Exchange Offer.

<PAGE>


                  If the Company effects the Registered  Exchange Offer, it will
be entitled to close such offer at the close of business 20 business  days after
commencement thereof provided that it has accepted all Notes theretofore validly
tendered in accordance with the terms of the Registered  Exchange  Offer.  Notes
not tendered in the Exchange  Offer shall bear interest at the rate specified in
the  Offering  Memorandum  and be  subject  to all of the terms  and  conditions
specified in the Indenture and to the transfer restrictions described therein.

(b) Shelf  Registration.  (i) If,  because  of any  change in law or  applicable
interpretations  thereof  by the staff of the  Commission,  the  Company  is not
permitted to effect the Exchange Offer as  contemplated  by Section 2(a) hereof,
or (ii) if for any other reason the Exchange Offer cannot be consummated  within
240 calendar days following the Closing Date, or (iii) if any Holder (other than
the Initial  Purchaser) is not eligible to  participate in the Exchange Offer or
does not receive  freely  tradable  Exchange Notes in the Exchange Offer or (iv)
upon the request of the Initial Purchaser (with respect to any Registrable Notes
which it acquired  directly from the Company)  following the consummation of the
Exchange Offer if the Initial  Purchaser shall hold  Registrable  Notes which it
acquired  directly  from  the  Company  and  if  the  Initial  Purchaser  is not
permitted,  in the  opinion of counsel to the  Initial  Purchaser,  pursuant  to
applicable  law or applicable  interpretation  of the staff of the Commission to
participate in the Exchange Offer, the Company shall, at its cost:

(A)      as  promptly  as   practicable,   file  with  the  Commission  a  Shelf
         Registration  Statement  relating  to the  offer  and  sale of the then
         outstanding  Registrable  Notes  by the  Holders  from  time to time in
         accordance  with the methods of  distribution  elected by the  Majority
         Holders  of  such  Registrable  Notes  and  set  forth  in  such  Shelf
         Registration Statement;

(B) use its best  efforts  to cause  such  Shelf  Registration  Statement  to be
declared  effective by the Commission under the Securities Act; (C) use its best
efforts to keep the Shelf Registration Statement continuously effective in order
to permit the Prospectus  forming part thereof to be usable by Holders until the
earlier  of (i) the time  when  the  Notes  covered  by the  Shelf  Registration
Statement can be sold pursuant to Rule 144 under the  Securities Act without any
limitations  under  clauses (c), (e), (f) and (h) of Rule 144 and (ii) two years
from the Closing Date; and (D)  notwithstanding any other provisions hereof, use
its best  efforts to ensure that (i) any Shelf  Registration  Statement  and any
amendment  thereto and any Prospectus  forming a part thereof and any supplement
thereto complies in all material  respects with the Securities Act and the rules
and  regulations  thereunder,  (ii) any  Shelf  Registration  Statement  and any
amendment  thereto  does  not,  when it  becomes  effective,  contain  an untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary to make the  statements  therein not misleading and
(iii) any Prospectus forming part of any Shelf Registration  Statement,  and any
supplement to such  Prospectus (as amended or  supplemented  from time to time),
does not  include  an untrue  statement  of a  material  fact or omit to state a
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.
                  The Company  further  agrees,  if necessary,  to supplement or
amend the Shelf Registration  Statement if reasonably  requested by the Majority
Holders with  respect to  information  relating to the Holders and  otherwise as
required by Section 3(b) below, to use all reasonable  efforts to cause any such
supplement  or  amendment to become  effective  and such Shelf  Registration  to
become usable as soon as practicable thereafter and to furnish to the Holders of
Registrable Notes copies of any such supplement or amendment  promptly after its
being used or filed with the Commission.

(c) Expenses. The Company shall pay all Registration Expenses in connection with
the  registration  pursuant to Section 2(a) and 2(b).  Each Holder shall pay all
expenses  of its  counsel  other  than as set forth in the  preceding  sentence,
underwriting  discounts and  commissions  (prior to the  reduction  thereof with
respect to selling concessions,  if any) and transfer taxes, if any, relating to
the sale or disposition of such Holder's Registrable Notes pursuant to the Shelf
Registration Statement.

(d) Effective Registration Statement. (i) The Company will be deemed not to have
used its best efforts to cause a Registration Statement to become, or to remain,
effective  during the  requisite  period if the  Company  voluntarily  takes any
action that would result in any such  Registration  Statement not being declared
effective or in the Holders of Registrable  Notes covered thereby not being able
to exchange or offer and sell such  Registrable  Notes during that period unless
(A) such action is required by applicable law or (B) such action is taken by the
Company  in good  faith  and for  valid  business  reasons  (but  not  including
avoidance  of  the  Company's  obligations  hereunder),   including  a  material
corporate  transaction,  so long  as the  Company  promptly  complies  with  the
requirements  of Section  3(k) hereof,  if  applicable.  (ii) An Exchange  Offer
Registration Statement pursuant to Section 2(a) hereof or a Shelf
         Registration  Statement  pursuant  to Section  2(b)  hereof will not be
         deemed to have become effective  unless it has been declared  effective
         by the  Commission;  provided,  however,  that  if,  after  it has been
         declared  effective,  the offering of  Registrable  Notes pursuant to a
         Registration Statement is interfered with by any stop order, injunction
         or  other  order  or   requirement  of  the  Commission  or  any  other
         governmental  agency  or court,  such  Registration  Statement  will be
         deemed  not  to  have  been   effective   during  the  period  of  such
         interference,  until the offering of Registrable Notes pursuant to such
         Registration Statement may legally resume.

<PAGE>


(e) Increase in Interest  Rate. In the event that either (i) the Exchange  Offer
Registration Statement is not filed with the Commission on or prior to the 180th
calendar day following the Closing Date, or (ii) the Exchange Offer Registration
Statement  is not  declared  effective  on or prior to the  210th  calendar  day
following the Closing Date, or (iii) the Exchange Offer is not consummated on or
prior  to  the  240th  calendar  day  following  the  Closing  Date  or a  Shelf
Registration  Statement  with respect to the  Registrable  Notes is not declared
effective on or prior to the 240th  calendar day  following the Closing Date, or
(iv) either (A) the Exchange Offer Registration Statement ceases to be effective
at any time prior to the time that the Exchange  Offer is  consummated or (B) if
applicable,  the Shelf  Registration  Statement has been declared  effective and
such Shelf  Registration  Statement  ceases to be effective at any time prior to
the second anniversary of the Closing Date, the interest rate borne by the Notes
shall be increased on the outstanding principle amount of the Notes by an amount
equal to 0.50% per annum following such 180-day period in the case of clause (i)
above, following such 210-day period in the case of clause (ii) above, following
such 240-day  period in the case of clause (iii) above,  or  immediately  in the
case of clause (iv) above. Such additional  interest will be payable at the same
time and in the same manner as  interest  is payable on the Notes.  Upon (w) the
filing of the Exchange  Offer  Registration  Statement  after the 180-day period
described in clause (i) above, (x) the consummation of the Exchange Offer or the
effectiveness of a Shelf Registration  Statement,  as the case may be, after the
240-day period  described in clause (iii) above,  (y) the  effectiveness  of the
Exchange Offer  Registration  Statement  after the 210-day  period  described in
clause (ii) above or (z) the  effectiveness  of the Exchange Offer  Registration
Statement or the Shelf  Registration  Statement  following an event described in
clause (iv) above,  the  interest  rate borne by the Notes from the date of such
filing,  effectiveness or  consummation,  as the case may be, will be reduced to
the original  interest rate if the Company is otherwise in compliance  with this
paragraph;  provided,  however,  that,  if after any such  reduction in interest
rate, an event specified in clauses (i), (ii),  (iii) or (iv) above occurs,  the
interest  rate will again be increased by an amount equal to 0.50% per annum and
thereafter reduced pursuant to the foregoing conditions.

         If the Company issues a notice that the Shelf Registration Statement is
unusable  pending  the  announcement  of a  material  corporate  transaction  or
otherwise  pursuant  to  Section  3(k) of this  Agreement,  or such a notice  is
required under applicable  securities laws to be issued by the Company,  and the
aggregate  number of days in any consecutive  twelve-month  period for which all
such  notices  are  issued  or  required  to be  issued  exceeds  30 days in the
aggregate,  then the interest rate borne by the Notes will be increased by 0.50%
per annum following the date that such Shelf Registration Statement ceases to be
usable beyond the 30-day period permitted above. Upon the Company declaring that
the Shelf  Registration  Statement is usable  after the  interest  rate has been
increased  pursuant to the  preceding  sentence,  the interest rate borne by the
Notes will be reduced to the original  interest rate if the Company is otherwise
in compliance with Section 2(e) of this Agreement,  provided,  however,  that if
after any such reduction in interest rate the Shelf Registration Statement again
ceases to be usable beyond the period  permitted  above,  the interest rate will
again be increased and thereafter reduced pursuant to the foregoing provisions.

         Notwithstanding  the  foregoing,  in no event shall the  interest  rate
borne by the Notes be increased pursuant to this Section 2(e) or Section 3(b) of
the  Warrant  Registration  Rights  Agreement  by an  amount  which  exceeds  an
aggregate of 0.50% per annum above the otherwise  applicable  per annum interest
rate.

(f) Specific Enforcement. Without limiting the remedies available to the Initial
Purchaser  and the  Holders,  the Company  acknowledges  that any failure by the
Company to comply with its respective  obligations  under Sections 2(a) and 2(b)
hereof may result in material irreparable injury to the Initial Purchaser or the
Holders  for  which  there is no  adequate  remedy  at law,  that it will not be
possible to measure  damages for such injuries  precisely and that, in the event
of any such failure,  the Initial Purchaser or any Holder may obtain such relief
as may be  required to  specifically  enforce the  Company's  obligations  under
Sections 2(a) and 2(b) hereof.

3.                Registration  Procedures.  In connection with the obligations 
of the Company  with respect to the Registration Statements pursuant to Sections
2(a) and 2(b) hereof, the Company shall:

the time  period  specified  in  Section  2, on the  appropriate  form under the
Securities  Act, which form (A) shall be selected by the Company,  (B) shall, in
the case of a Shelf  Registration,  be available for the sale of the Registrable
Notes by the  selling  Holders  thereof  and (C) shall  comply as to form in all
material  respects with the  requirements  of the applicable form and include or
incorporate by reference all financial  statements required by the Commission to
be filed  therewith,  and (ii) use its best  efforts to cause such  Registration
Statement to become  effective and remain effective in accordance with Section 2
hereof;

keep  such  Shelf  Registration  Statement  effective  for the  period  required
pursuant to Section 2(b) hereof;  (ii) cause each  Prospectus to be supplemented
by any  required  prospectus  supplement,  and as so  supplemented  to be  filed
pursuant  to Rule 424 under  the  Securities  Act;  and  (iii)  comply  with the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
securities  covered by each Registration  Statement during the applicable period
in accordance with the intended method or methods of distribution by the selling
Holders thereof; (c) in the case of a Shelf Registration, (i) notify each Holder
of  Registrable  Notes,  at  least  ten  days  prior  to  filing,  that a  Shelf

advising such Holders that the distribution of Registrable Notes will be made in
accordance with the method elected by the Majority Holders; (ii) furnish to each

declared   effective  by  the  Commission,   keep  each  such   registration  or
qualification  effective  during  the  period  such  Registration  Statement  is
required to be  effective  and do any and all other acts and things which may be
reasonably  necessary  or  advisable  to enable  such Holder to  consummate  the
disposition in each such  jurisdiction of such  Registrable  Notes owned by such
Holder,  and to  cooperate  with the  Holders  in  connection  with any  filings
required to be made with the NASD; provided, however, that the Company shall not
be required to (i) qualify as a foreign corporation or as a dealer in securities
in any jurisdiction  where it would not otherwise be required to qualify but for

respects,  (v) of the receipt by the Company of any notification with respect to
the suspension of the  qualification  of the  Registrable  Notes for sale in any
jurisdiction  or the  initiation  or  threatening  of any  proceeding  for  such
purpose, (vi) of the happening of any event or the discovery of any facts during
the period a Shelf Registration Statement is effective which makes any statement
made in such Shelf  Registration  Statement or the related  Prospectus untrue in
any material  respect or which  requires the making of any changes in such Shelf
Registration  Statement or  Prospectus  in order to make the  statements  in the
Shelf Registration Statement, at the time it became effective, not misleading or
to make the statements in the Prospectus in the light of the circumstances under
which they were made,  at the date  thereof,  not  misleading,  and (vii) of any

Broker-Dealer"),  and who receives Exchange Notes for Registrable Notes pursuant
to the  Exchange  Offer,  may be a  statutory  underwriter  and must  deliver  a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange  Notes,  (D) subject to the last paragraph of Section 3,

covered by the  Prospectus  or any  amendment  or  supplement  thereto,  and (E)
include in the transmittal letter or similar  documentation to be executed by an
exchange offeree in order to participate in the Exchange Offer (1) the following
provision:  "If  the  undersigned  is  not  a  broker-dealer,   the  undersigned
represents  that it is not  engaged  in,  and does not  intend to  engage  in, a
distribution of Exchange Notes. If the undersigned is a broker-dealer  that will
receive Exchange Notes for its own account in exchange for Registrable Notes, it
represents  that the  Registrable  Notes to be exchanged for Exchange Notes were
acquired  by it  as a  result  of  market-making  activities  or  other  trading
activities  and  acknowledges  that it will  deliver a  prospectus  meeting  the
requirements  of the  Securities  Act in  connection  with  any  resale  of such
Exchange Notes pursuant to the Exchange Offer;  however, by so acknowledging and
by delivering a prospectus,  the undersigned will not be deemed to admit that it
is an  "underwriter"  within  the  meaning  of the  Securities  Act";  and (2) a
statement  to the  effect  that by a  broker-dealer  making  the  acknowledgment
described in subclause (1) and by delivering a Prospectus in connection with the
exchange of Registrable Securities, the broker-dealer will not be deemed to have
admitted that it is an underwriter within the meaning of the Securities Act; and
(ii) to the extent any Participating  Broker-Dealer participates in the Exchange
Offer, the Company
         shall use its best  efforts to cause to be  delivered at the request of
         an entity representing the Participating  Broker-Dealers  (which entity
         shall be the  Initial  Purchaser,  unless it elects  not to act as such
         representative) only one, if any, "cold comfort" letter with respect to
         the  Prospectus  in the  form  existing  on the  last  date  for  which
         exchanges are accepted  pursuant to the Exchange Offer and with respect
         to each subsequent amendment or supplement, if any, effected during the
         period specified in clause (iii) below; and
<PAGE>


(iii) to the extent any Participating Broker-Dealer participates in the Exchange
Offer,  the Company shall use its best efforts to maintain the  effectiveness of
the Exchange Offer Registration Statement for a period of 180 days following the
closing  of  the  Exchange  Offer  and  make  available  the  Prospectus  to any
Participating Broker-Dealer; and (iv) the Company shall not be required to amend
or  supplement  the  Prospectus  contained  in the Exchange  Offer  Registration
Statement as would  otherwise be contemplated by Section 3(b), or take any other
action as a result of this Section 3(f),  for a period  exceeding 180 days after
the last date for which  exchanges are accepted  pursuant to the Exchange  Offer
(as such period may be extended by the Company) and Participating Broker-Dealers
shall  not be  authorized  by the  Company  to,  and  shall  not,  deliver  such
Prospectus  after such period in connection  with resales  contemplated  by this
Section 3. (g) (i) in the case of an Exchange Offer,  furnish to counsel for the
Initial  Purchaser  and (ii) in the  case of a Shelf  Registration,  furnish  to
counsel  for the  Holders  of  Registrable  Notes  copies of any  request by the
Commission or any state securities  authority for amendments or supplements to a
Registration Statement and Prospectus or for additional information;

(h)  make  every  reasonable  effort  to  obtain  the  withdrawal  of any  order
suspending the effectiveness of a Registration  Statement as soon as practicable
and provide immediate notice to each Holder of the withdrawal of any such order;
(i) in the case of a Shelf  Registration,  furnish to each Holder of Registrable
Notes,  without  charge,  at  least  one  conformed  copy of  each  Registration
Statement  and  any   post-effective   amendment   thereto  (without   documents
incorporated therein by reference or exhibits thereto, unless requested); (j) in
the  case of a  Shelf  Registration,  cooperate  with  the  selling  Holders  of
Registrable  Notes  to  facilitate  the  timely   preparation  and  delivery  of
certificates  representing  Registrable  Notes  to be sold and not  bearing  any
restrictive   legends;   and  cause  such  Registrable   Notes  to  be  in  such
denominations  (consistent  with the provisions of the Indenture) and registered
in such names as the selling Holders or the underwriters, if any, may reasonably
request  at  least  one  business  day  prior  to the  closing  of any  sale  of
Registrable Notes; (k) in the case of a Shelf Registration,  upon the occurrence
of any event or the  discovery  of any facts,  each as  contemplated  by Section
3(e)(vi) hereof,  use its best efforts to prepare a supplement or post-effective
amendment to a Registration  Statement or the related Prospectus or any document
incorporated  therein by reference or file any other required  document so that,
as  thereafter  delivered  to the  purchasers  of the  Registrable  Notes,  such
Prospectus will not contain at the time of such delivery any untrue statement of
a  material  fact  or omit  to  state a  material  fact  necessary  to make  the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading.  The Company agrees to notify each Holder to suspend use of the
Prospectus as promptly as practicable after the occurrence of such an event, and
each Holder hereby agrees to suspend use of the Prospectus until the Company has
amended or supplemented the Prospectus to correct such misstatement or omission.
At  such  time  as such  public  disclosure  is  otherwise  made or the  Company
determines  that such  disclosure is not necessary,  in each case to correct any
misstatement  of a material fact or to include any omitted  material  fact,  the
Company  agrees  promptly  to notify each  Holder of such  determination  and to
furnish  each Holder  such  numbers of copies of the  Prospectus,  as amended or
supplemented,  as such Holder may reasonably request;  (l) obtain a CUSIP number
for all Exchange Notes, or Registrable Notes, as the case may be, not later than
the effective  date of a  Registration  Statement,  and provide the Trustee with
printed  certificates  for the Exchange Notes or the  Registrable  Notes, as the
case may be, in a form eligible for deposit with the  Depositary;  (m) (i) cause
the Indenture to be qualified  under the Trust Indenture Act of 1939, as amended
(the "TIA"),  in connection  with the  registration  of the Exchange  Notes,  or
Registrable  Notes,  as the case may be, (ii) cooperate with the Trustee and the
Holders to effect  such  changes to the  Indenture  as may be  required  for the
Indenture to be so qualified in  accordance  with the terms of the TIA and (iii)
execute, and use its best efforts to cause the Trustee to execute, all documents
as may be  required to effect such  changes,  and all other forms and  documents
required  to be filed  with the  Commission  to enable  the  Indenture  to be so
qualified in a timely  manner;  (n) in the case of a Shelf  Registration,  enter
into agreements (including underwriting agreements) and take all other customary
and appropriate  actions  (including those reasonably  requested by the Majority
Holders) in order to expedite or facilitate the disposition of such  Registrable
Notes and in such connection whether or not an underwriting agreement is entered
into and whether or not the  registration is an underwritten  registration:  (i)
make such  representations  and  warranties  to the Holders of such  Registrable
Notes and the
         underwriters,  if any, in form,  substance and scope as are customarily
         made by issuers to  underwriters in similar  underwritten  offerings as
         may be reasonably requested by them;

(ii)  obtain  opinions of counsel to the  Company  and  updates  thereof  (which
counsel  and  opinions  (in  form,  scope  and  substance)  shall be  reasonably
satisfactory to the managing underwriters, if any, and the holders of a majority
in  principal  amount of the  Registrable  Notes being sold)  addressed  to each
selling Holder and the underwriters,  if any,  covering the matters  customarily
covered in opinions requested in sales of securities or underwritten  offerings;
(iii)  obtain "cold  comfort"  letters and updates  thereof  from the  Company's
independent certified public accountants addressed to the underwriters,  if any,
and use best  efforts to have such letters  addressed to the selling  Holders of
Registrable  Notes, such letters to be in customary form and covering matters of
the type  customarily  covered  in "cold  comfort"  letters to  underwriters  in
connection  with similar  underwritten  offerings;  (iv) enter into a securities
sales  agreement  with the Holders and an agent of the  Holders  providing  for,
among other things,  the  appointment of such agent for the selling  Holders for
the purpose of soliciting  purchases of Registrable Notes, which agreement shall
be in form, substance and scope customary for similar offerings; and (v) deliver
such  documents  and  certificates  as may be  reasonably  requested  and as are

<PAGE>

customarily  delivered in similar offerings.  The above shall be done at (i) the
effectiveness of such Shelf  Registration  Statement (and, if appropriate,  each
post-effective  amendment  thereto) and (ii) each closing under any underwriting
or similar  agreement as and to the extent required  thereunder.  In the case of
any  underwritten  offering,  the Company  shall provide  written  notice to the
Holders of all Registrable Notes of such underwritten  offering at least 30 days
(or such shorter,  reasonable time period as is practicable) prior to the filing
of a prospectus supplement for such underwritten offering. Such notice shall (x)
if  satisfactory  to the  investment  banker  or  manager  of such  underwritten
offering,  offer each such Holder the right to participate in such  underwritten
offering,  (y) specify a date,  which shall be no earlier than 10 days following
the date of such  notice,  by which such  Holder  must inform the Company of its
intent  to  participate  in  such  underwritten  offering  and (z)  include  the
instructions   such  Holder  must  follow  in  order  to   participate  in  such
underwritten offering;

(o) in the  case of a Shelf  Registration,  make  available  for  inspection  by
representatives  of the Holders of the  Registrable  Notes and any  underwriters
participating in any disposition pursuant to a Shelf Registration  Statement and
any  counsel  or  accountant  retained  by  such  Holders  or  underwriters,  at
reasonable  times and in a reasonable  manner,  all financial and other records,
pertinent corporate documents and properties of the Company reasonably requested
by any such persons,  and cause the respective officers,  directors,  employees,
and any  other  agents  of the  Company  to supply  all  information  reasonably
requested by any such representative, underwriter, special counsel or accountant
in connection with such Shelf Registration  Statement;  provided,  however, that
such Persons shall first agree in writing with the Company that any  information
that is  reasonably  and in good faith  designated  by the Company in writing as
confidential  at the  time  of  delivery  of  such  information  shall  be  kept
confidential  by such  Persons,  unless (i)  disclosure of such  information  is
required  by court  or  administrative  order  or is  necessary  to  respond  to
inquiries of regulatory  authorities,  (ii)  disclosure of such  information  is
required  by law  (including  any  disclosure  requirements  pursuant to Federal
securities  laws in  connection  with  the  filing  of such  Shelf  Registration
Statement  or  the  use of  any  Prospectus),  (iii)  such  information  becomes
generally  available  to the public  other than as a result of a  disclosure  or
failure to safeguard such  information  by such Person or (iv) such  information
becomes  available  to such Person from a source  other than the Company and its
Subsidiary  Guarantors  and  such  source  is  not  bound  by a  confidentiality
agreement;  and provided,  further,  that the foregoing  investigation  shall be
coordinated on behalf of the Holders by one representative  designated by and on
behalf of such Holders and any such confidential  information shall be available
from such  representative  to such  Holders so long as any  Holder  agrees to be
bound by such confidentiality agreement;

(p) (i) a reasonable time prior to the filing of any Exchange Offer Registration
Statement,  any Prospectus forming a part thereof,  any amendment to an Exchange
Offer Registration Statement or amendment or supplement to a Prospectus, provide
copies of such document to the Initial Purchaser,  and, subject to the rights of
the Company to issue the notice contemplated contemplated by Section 3(k) hereof
and suspend the use of the  Registration  Statement and Prospectus under Section
2(e) hereof,  make such changes in any such document prior to the filing thereof
as the Initial Purchaser or its counsel may reasonably request; (ii) in the case
of  a  Shelf  Registration,   a  reasonable  time  prior  to  filing  any  Shelf
Registration Statement,  any Prospectus forming a part thereof, any amendment to
such Shelf Registration Statement or amendment or supplement to such Prospectus,
provide  copies of such  document to the Holders of  Registrable  Notes,  to the
Initial Purchaser, to counsel on behalf of the Holders and to the underwriter or
underwriters  of an  underwritten  offering of Registrable  Notes,  if any, and,
subject  to  the  rights  of  the  Company  to  issue  the  notice  contemplated
contemplated  by Section  3(k) hereof and  suspend  the use of the  Registration
Statement and  Prospectus  under  Section 2(e) hereof,  make such changes in any
such document prior to the filing  thereof as the Holders of Registrable  Notes,
the  Initial  Purchaser  on  behalf  of  such  Holders,  their  counsel  or  any
underwriter may reasonably  request;  and (iii) cause the representatives of the
Company to be available  for  discussion of such document as shall be reasonably
requested by the Holders of Registrable  Notes, the Initial  Purchaser on behalf
of such Holders, their counsel or any underwriter and shall not at any time make
any filing of any such document of which such Holders,  the Initial Purchaser on
behalf  of such  Holders,  their  counsel  or any  underwriter  shall  not  have
previously  been  advised  and  furnished a copy or to which such  Holders,  the
Initial  Purchaser on behalf of such Holders,  their counsel or any  underwriter
shall  reasonably  object,  each of which  actions in this  clause  (iii) by the
Holders  shall be  coordinated  by one  representative  for all the  Holders  at
reasonable  times  and  in a  reasonable  manner;  (q) in the  case  of a  Shelf
Registration,  use its best efforts to cause all  Registrable  Securities  to be
listed on any securities exchange on which similar debt securities issued by the
Company  are  then  listed  if  requested  by  the  Majority  Holders  or by the
underwriter  or  underwriters   of  an  underwritten   offering  of  Registrable
Securities,  if any; (r) in the case of a Shelf Registration,  unless the rating
in effect for the Notes  applies to the Exchange  Notes and the Notes to be sold
pursuant to a Shelf Registration,  use its best efforts to cause the Registrable
Notes to be rated with the appropriate  rating agencies,  if so requested by the
Majority  Holders  or by the  underwriter  or  underwriters  of an  underwritten
offering of Registrable  Notes, if any, unless the Registrable Notes are already
so rated; (s) otherwise use its best efforts to comply with all applicable rules
and regulations of the Commission and make available to its security holders, as
soon as  reasonably  practicable,  an  earnings  statement  covering at least 12
months which shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder; and (t) cooperate and assist in any filings required to
be made with the NASD.

<PAGE>


                  In the case of a Shelf Registration Statement, the Company may
(as a  condition  to such  Holder's  participation  in the  Shelf  Registration)
require  each  Holder  of  Registrable  Notes to  furnish  to the  Company  such
information  regarding such Holder and the proposed  distribution by such Holder
of such Registrable  Notes and make such  representations,  in each case, as the
Company may from time to time reasonably request in writing.

                  In the case of a Shelf  Registration  Statement,  each  Holder
agrees that, upon receipt of any notice from the Company of the happening of any
event or the  discovery  of any  facts,  each of the kind  described  in Section
3(e)(ii)-(vii)  hereof,  such Holder will forthwith  discontinue  disposition of
Registrable  Notes  pursuant to a  Registration  Statement  until such  Holder's
receipt of the copies of the supplemented or amended Prospectus  contemplated by
Section  3(k)  hereof,  and,  if so directed  by the  Company,  such Holder will
deliver to the Company (at the Company's  expense) all copies in its possession,
other than  permanent  file  copies  then in such  Holder's  possession,  of the
Prospectus  covering  such  Registrable  Notes current at the time of receipt of
such  notice.  If the  Company  shall  give  any  such  notice  to  suspend  the
disposition of Registrable Notes pursuant to a Shelf Registration Statement as a
result of the happening of any event or the discovery of any facts,  each of the
kind described in Section 3(e)(vi)  hereof,  the Company shall be deemed to have
used its best efforts to keep the Shelf Registration  Statement effective during
such period of  suspension  provided that the Company shall use its best efforts
to file and have declared  effective (if an amendment) as soon as practicable an
amendment or supplement to the Shelf Registration Statement and shall extend the
period during which the  Registration  Statement  shall be maintained  effective
pursuant  to this  Agreement  by the number of days  during the period  from and
including  the date of the giving of such notice to and  including the date when
the Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions.

4.  Underwritten  Registrations.  If any of the Registrable Notes covered by any
Shelf  Registration are to be sold in an underwritten  offering,  the investment
banker or  investment  bankers  and  manager or  managers  that will  manage the
offering  will be selected by the  Majority  Holders of such  Registrable  Notes
included in such offering and shall be reasonably acceptable to the Company.

                  No  Holder  of  Registrable   Notes  may  participate  in  any
underwritten  registration  hereunder unless such Holder (a) agrees to sell such
Holder's   Registrable   Notes  on  the  basis  provided  in  any   underwriting
arrangements  approved  by  the  persons  entitled  hereunder  to  approve  such
arrangements  and (b)  completes  and  executes  all  questionnaires,  powers of
attorney,  indemnities,  underwriting  agreements and other  documents  required
under the terms of such underwriting arrangements.

5.  Indemnification  and  Contribution.  (a) The  Company  and  each  Subsidiary
Guarantor,  jointly and  severally,  agree to indemnify  and hold  harmless each
Holder and each person,  if any,  who controls any Holder  within the meaning of
Section 15 of the  Securities  Act or Section 20 of the Exchange Act against any
losses, claims,  damages or liabilities,  joint or several, to which such Holder
or such  controlling  person may become  subject under the  Securities  Act, the
Exchange  Act  or  otherwise,   insofar  as  such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) arise out of or are based upon:

(i)               any untrue  statement or alleged  untrue  statement  made by 
         the Company or any of the Subsidiary
         Guarantors of any material fact contained in the Offering Memorandum,

(ii) any untrue  statement or alleged  untrue  statement  of any  material  fact
contained in (A) any  Registration  Statement or  Prospectus or any amendment or
supplement thereto or (B) any application or other document, or any amendment or
supplement  thereto,  executed by the Company or based upon written  information
furnished by or on behalf of the Company filed in any  jurisdiction  in order to
qualify the Registrable Notes or Exchange Notes under the securities or blue sky
laws  thereof or filed with the  Commission  or any  securities  association  or
securities  exchange (each an  "Application"),  or (iii) the omission or alleged
omission to state in any Registration Statement or Prospectus or any
         amendment or  supplement  thereto,  or any  Application a material fact
         required to be stated in such  Registration  Statement  or necessary to
         make the  statements  in such  Registration  Statement,  at the time it
         became  effective,  not  misleading,  or  required to be stated in such
         Prospectus or any supplement or amendment  thereto or necessary to make
         the statements in such Prospectus, at the date thereof, in the light of
         the circumstances under which they were made, not misleading,

and will reimburse,  as incurred,  each Holder and each such controlling  person
for any  legal or other  expenses  reasonably  incurred  by such  Holder or such
controlling  person in  connection  with  investigating,  defending  against  or
appearing as a  third-party  witness in  connection  with any such loss,  claim,
damage,  liability  or action;  provided,  however,  that the  Company  and each
Subsidiary Guarantor, jointly and severally, will not be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon any untrue  statement  or alleged  untrue  statement  or  omission or
alleged  omission  made  in any  Registration  Statement  or  Prospectus  or any
amendment  or  supplement  thereto or any  Application  in reliance  upon and in
conformity  with  written  information  relating to any Holder  furnished to the
Company  by  such  Holder   specifically   for  use   therein.   The   foregoing
indemnification  with respect to any preliminary  Prospectus or final Prospectus
shall not inure to the  benefit of any  Holder (or to the  benefit of any person
controlling  such  Holder)  if the person  asserting  any such  losses,  claims,
damages,  liabilities  or expenses was not sent or delivered a copy of the final
Prospectus (or the final  Prospectus as amended or  supplemented) at or prior to
the written  confirmation  of the sale of Notes to such person and if the untrue
statement  or  omission  of  a  material  fact  contained  in  such  preliminary
Prospectus  was corrected in the final  Prospectus  (or the final  Prospectus as
amended or supplemented)  unless such corrected final Prospectus was not sent or
delivered  because  the  Company  failed  to timely  provide  such  Holder  with
sufficient copies of such corrected final Prospectus.  This indemnity  agreement
will be in addition  to any  liability  which the  Company  and each  Subsidiary
Guarantor,  jointly and  severally,  may otherwise  have to any Holder or to any
person  who  controls  such  Holder  within  the  meaning  of  Section 15 of the
Securities Act or Section 20 of the Exchange Act.

<PAGE>


(b) Each Holder,  severally and not jointly,  agrees, by acquiring any Notes, to
indemnify  and hold  harmless the Company,  each of its  directors,  each of its
executive  officers and each person, if any, who controls the Company within the
meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange Act
against any losses,  claims,  damages or liabilities  to which the Company,  any
such  director,  officer or  controlling  person may  become  subject  under the
Securities  Act or  otherwise,  insofar  as  such  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof) arise out of or are based upon (i)
any untrue  statement or alleged untrue statement of any material fact contained
in any  Registration  Statement or  Prospectus  or any  amendment or  supplement
thereto or any Application or (ii) the omission or alleged  omission to state in
any Registration Statement or Prospectus or any amendment or supplement thereto,
or any  Application a material  fact required to be stated in such  Registration
Statement or necessary to make the statements in such Registration Statement, at
the time it became effective,  not misleading,  or required to be stated in such
Prospectus  or any  supplement  or  amendment  thereto or  necessary to make the
statements  in  such  Prospectus,  at the  date  thereof,  in the  light  of the
circumstances  under which they were made, not  misleading,  in each case to the
extent,  but only to the extent,  that such untrue  statement or alleged  untrue
statement  or omission  or alleged  omission  was made in  reliance  upon and in
conformity  with  written  information  relating to any Holder  furnished to the
Company  by such  Holder  specifically  for use  therein;  and,  subject  to the
limitation set forth  immediately  preceding  this clause,  will  reimburse,  as
incurred,  any legal or other expenses reasonably incurred by the Company or any
such director, officer or controlling person in connection with investigating or
defending  any such  loss,  claim,  damage,  liability  or any action in respect
thereof. In no event shall any Holder, its directors, officers or any person who
controls  such Holder be liable or  responsible  for any amount in excess of the
amount by which the total  amount  received by such  Holder with  respect to its
sale of Registrable  Notes pursuant to a Registration  Statement exceeds (i) the
amount paid by such Holder for such Registrable Notes and (ii) the amount of any
damages that such  Holder,  its  directors,  officers or any person who controls
such  Holder has  otherwise  been  required  to pay by reason of such  untrue or
alleged  untrue  statement  or  omission  or alleged  omission.  This  indemnity
agreement  will be in addition to any liability  which such Holder may otherwise
have.

(c)  Promptly  after  receipt by an  indemnified  party under this  Section 5 of
notice of the  commencement  of any action,  such  indemnified  party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 5, notify the indemnifying party of the commencement thereof in writing;
but the  omission so to notify the  indemnifying  party will not relieve it from
any liability  which it may have to any  indemnified  party otherwise than under
this  Section 5. In case any such  action is  brought  against  any  indemnified
party, and it notifies the indemnifying party of the commencement  thereof,  the
indemnifying  party will be entitled to  participate  therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly  notified,
to assume and control the defense  thereof,  with counsel  satisfactory  to such
indemnified party; provided,  however, that if the defendants in any such action
include  both  the  indemnified  party  and  the  indemnifying   party  and  the
indemnified party shall have reasonably  concluded that there may be one or more
legal  defenses  available  to it and/or  other  indemnified  parties  which are
different from or additional to those available to the  indemnifying  party, the
indemnifying party shall not have the right to direct the defense of such action
on behalf of such  indemnified  party or parties and such  indemnified  party or
parties shall have the right to select separate counsel to defend such action on
behalf of such indemnified party or parties.  After notice from the indemnifying
party to such  indemnified  party of its election to assume the defense  thereof
and  approval  by such  indemnified  party of counsel  appointed  to defend such
action,  the  indemnifying  party will not be liable to such  indemnified  party
under this  Section 5 for any legal or other  expenses,  other  than  reasonable
costs of  investigation,  subsequently  incurred  by such  indemnified  party in
connection with the defense thereof, unless (i) the indemnified party shall have
employed  separate  counsel in accordance with the proviso to the next preceding
sentence (it being understood,  however, that in connection with such action the
indemnifying  party  shall  not be  liable  for the  expenses  of more  than one
separate  counsel (in  addition to local  counsel) in any one action or separate
but substantially  similar actions in the same  jurisdiction  arising out of the
same general allegations or circumstances, designated by such Holder in the case
of paragraph (a) of this Section 5,  representing the indemnified  parties under
such  paragraph  (a) who are  parties  to such  action or  actions)  or (ii) the
indemnifying  party  does  not  promptly  retain  counsel  satisfactory  to  the
indemnified party or (iii) the indemnifying  party has authorized the employment
of counsel for the indemnified  party at the expense of the indemnifying  party.
After such notice from the  indemnifying  party to such  indemnified  party, the
indemnifying  party  will  not be  liable  for the  costs  and  expenses  of any
settlement of such action effected by such indemnified party without the consent
of the  indemnifying  party. No  indemnifying  party shall (A) without the prior
written  consent  of  the  indemnified  parties  (which  consent  shall  not  be
unreasonably  withheld)  settle or  compromise  or  consent  to the entry of any
judgment  with  respect to any  pending or  threatened  claim,  action,  suit or
proceeding in respect of which  indemnification  or  contribution  may be sought
hereunder  (whether  or not the  indemnified  parties  are  actual or  potential
parties to such claim or action) unless such  settlement,  compromise or consent
(1)  includes  an  unconditional  release  of each  indemnified  party  from all
liability arising out of such claim, action, suit or proceeding and (2) does not
include a statement as to or an admission of fault,  culpability or a failure to
act by or on  account  of any  indemnified  party,  or (B)  be  liable  for  any
settlement  of any such  action  effected  without its  written  consent  (which
consent shall not be unreasonably withheld),  but if settled with the consent of
the  indemnifying  party or if there be a final judgment of the plaintiff in any

<PAGE>


such action,  the  indemnifying  party agrees to indemnify and hold harmless any
indemnified  party  from and  against  any loss or  liability  by reason of such
settlement or judgment.  (d) In circumstances  in which the indemnity  agreement
provided for in the  preceding  paragraphs of this Section 5 is  unavailable  or
insufficient,  for any reason,  to hold harmless an indemnified party in respect
of any losses,  claims,  damages or liabilities (or actions in respect thereof),
each   indemnifying   party,   in  order  to  provide  for  just  and  equitable
contribution, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses,  claims, damages or liabilities (or actions in
respect  thereof)  in such  proportion  as is  appropriate  to  reflect  (i) the
relative benefits received by the indemnifying  party or parties on the one hand
and the  indemnified  party on the other from the offering of the  Securities or
(ii) if the allocation  provided by the foregoing clause (i) is not permitted by
applicable  law, not only such relative  benefits but also the relative fault of
the indemnifying  party or parties on the one hand and the indemnified  party on
the other in connection  with the statements or omissions or alleged  statements
or omissions that resulted in such losses,  claims,  damages or liabilities  (or
actions  in  respect  thereof),   as  well  as  any  other  relevant   equitable
considerations.  The  relative  fault  of the  parties  shall be  determined  by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged  omission to state a material fact
relates to  information  supplied by the Company or such  Holder,  the  parties'
relative intents, knowledge, access to information and opportunity to correct or
prevent  such  statement  or omission,  and any other  equitable  considerations
appropriate in the  circumstances.  The amount paid or payable by an indemnified
party as a result of the  losses,  claims,  damages,  liabilities  or  judgments
referred  to above shall be deemed to include,  subject to the  limitations  set
forth in Section 5(b), any legal or other fees or expenses  reasonably  incurred
by such  indemnified  party in connection  with  investigating  or defending any
matter,  including any action that could have given rise to such losses, claims,
damages, liabilities or judgments.
         The Company,  each  Subsidiary  Guarantor and each Holder agree that it
would  not be  just  and  equitable  if the  amount  of such  contribution  were
determined  by pro  rata or per  capita  allocation  (even if the  Holders  were
treated as one entity for such  purpose)  or by any other  method of  allocation
that does not take into account the equitable  considerations  referred to above
in this paragraph  (d).  Notwithstanding  any other  provision of this paragraph
(d), no Holder shall be obligated to make  contributions  hereunder  that in the
aggregate  exceed  the total  public  offering  price of the  Registrable  Notes
purchased by such Holder under this Agreement,  less the aggregate amount of any
damages that such Holder has  otherwise  been  required to pay in respect of the
same or any  substantially  similar  claim,  and no person  guilty of fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation. The Holders' obligations to contribute pursuant to
this Section are several in proportion  to the  respective  principal  amount of
Registrable  Notes held by each Holder  hereunder and not joint. For purposes of
this  paragraph  (d),  each person,  if any,  who  controls a Holder  within the
meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange Act
shall have the same rights to contribution as such Holder,  and each director of
the Company,  each officer of the Company who signed the Registration  Statement
and each person,  if any, who controls the Company within the meaning of Section
15 of the  Securities Act or Section 20 of the Exchange Act, shall have the same
rights to contribution as the Company.

(e) The Issuer and each of the  Subsidiary  Guarantors  agree that the indemnity
and  contribution  provisions  of this  Section  5 shall  apply  to the  Initial
Purchaser  to the same  extent,  on the same  conditions,  as they  apply to the
Holders.

(f) The parties to this Agreement hereby acknowledge that they are sophisticated
business  persons  who were  represented  by  counsel  during  the  negotiations
regarding the provisions of this Agreement,  including,  without limitation, the
provisions of this Section 5, and are fully informed  regarding said provisions.
They further  acknowledge  that the provisions of this Section 5 fairly allocate
the risks in light of the ability of the parties to investigate  the Company and
its  business  in  order  to  assure  that  adequate  disclosure  is made in the
Registration  Statement  as  required  by the  Securities  Act.  The parties are
advised that federal or state policy,  as  interpreted  by the courts in certain
jurisdictions,  may be contrary to certain provisions of this Section 5, and the
parties  hereto hereby  expressly  waive and  relinquish any right or ability to
assert  such  public  policy as a defense to a claim  under  this  Section 5 and
further agree not to attempt to assert any such defense. 6.  Miscellaneous.  (a)
Rule 144 and Rule 144A.  For so long as the Company is subject to the  reporting
requirements  of Sections 13 or 15 of the Exchange  Act,  the Company  covenants
that it will file the reports required to be filed by it under Sections 13(a) or
15(d)  of the  Exchange  Act  and  the  rules  and  regulations  adopted  by the
Commission thereunder.  The Company further covenants that if it ceases to be so
required  to file  such  reports,  it will  upon the  request  of any  Holder of
Registrable  Notes (i) make publicly  available such information as is necessary
to permit sales pursuant to Rule 144 under the Securities Act, (ii) deliver such
information to a prospective  purchaser as is necessary to permit sales pursuant
to Rule 144A under the  Securities  Act and it will take such further  action as
any Holder of  Registrable  Notes may  reasonably  request,  and (iii) take such
further  action that is  reasonable in the  circumstances,  in each case, to the
extent  required from time to time to enable such Holder to sell its Registrable
Notes without registration under the Securities Act within the limitation of the
exemptions  provided by (x) Rule 144 under the Securities  Act, as such Rule may
be amended from time to time,  (y) Rule 144A under the  Securities  Act, as such
Rule may be amended from time to time, or (z) any similar  rules or  regulations
hereafter  adopted  by  the  Commission.  Upon  the  request  of any  Holder  of
Registrable  Notes, the Company will deliver to such Holder a written  statement
as to whether it has complied with such requirements.

<PAGE>


(b) No  Inconsistent  Agreements.  The Company has not entered into nor will the
Company on or after the date of this Agreement enter into any agreement which is
inconsistent with the rights granted to the Holders of Registrable Notes in this
Agreement or otherwise  conflicts with the provisions hereof. The rights granted
to  the  Holders  hereunder  do not  in  any  way  conflict  with  and  are  not
inconsistent  with the rights  granted to the  holders  of the  Company's  other
issued and outstanding securities under any such agreements.

(c) Amendments  and Waivers.  The  provisions of this  Agreement,  including the
provisions of this sentence, may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the  provisions  hereof may not be given
unless the Company  has  obtained  the written  consent of Holders of at least a
majority in aggregate  principal  amount of the  outstanding  Registrable  Notes
affected  by such  amendment,  modification,  supplement,  waiver or  departure;
provided,  however,  that no  amendment,  modification,  supplement or waiver or
consent  to any  departure  from the  provisions  of  Section 5 hereof  shall be
effective  as against any Holder of  Registrable  Notes  unless  consented to in
writing by such  Holder.  (d)  Notices.  All  notices  and other  communications
provided for or permitted  hereunder shall be made in writing by  hand-delivery,
registered first-class mail,  telecopier,  or any courier guaranteeing overnight
delivery  (i) if to a Holder  (other  than the Initial  Purchaser),  at the most
current  address set forth on the records of the Registrar  under the Indenture,
(ii) if to the Initial  Purchaser,  at the most  current  address  given by such
Initial  Purchaser to the Company by means of a notice given in accordance  with
the provisions of this Section 6(d), which address  initially is the address set
forth in the Purchase Agreement;  and (iii) if to the Company,  initially at the
Company's  address set forth in the Purchase  Agreement  and  thereafter at such
other  address,  notice of which is given in accordance  with the  provisions of
this Section 6(d).
                  All such  notices and  communications  shall be deemed to have
been duly given:  at the time delivered by hand, if personally  delivered;  five
business days after being  deposited in the mail,  postage  prepaid,  if mailed;
when receipt is  acknowledged,  if  telecopied;  and on the next business day if
timely delivered to an air courier guaranteeing overnight delivery.

                  Copies of all such notices,  demands, or other  communications
shall be concurrently delivered by the Person giving the same to the Trustee, at
the address specified in the Indenture.

(e) Successors and Assigns.  This Agreement shall inure to the benefit of and be
binding upon the  successors,  assigns and  transferees  of each of the parties,
including,  without  limitation and without the need for an express  assignment,
subsequent  Holders;  provided that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Registrable Securities in violation
of the terms  hereof  or of the  Purchase  Agreement  or the  Indenture.  If any
transferee of any Holder shall acquire Registrable Notes, in any manner, whether
by operation of law or otherwise,  such Registrable  Notes shall be held subject
to  all of  the  terms  of  this  Agreement,  and by  taking  and  holding  such
Registrable Notes, such Person shall be conclusively deemed to have agreed to be
bound by and to  perform  all of the terms  and  provisions  of this  Agreement,
including  the  restrictions  on resale  set  forth in this  Agreement  and,  if
applicable, the Purchase Agreement, and such Person shall be entitled to receive
the benefits hereof.

(f)  Third  Party  Beneficiary.  Each  of  the  Holders  shall  be  third  party
beneficiaries  to the agreements  made hereunder  between the Company on the one
hand, and the Initial Purchaser,  on the other hand, and shall have the right to
enforce  such  agreements  directly  to the  extent  it deems  such  enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.
(g)  Counterparts.  This Agreement may be executed in any number of counterparts
and by the  parties  hereto  in  separate  counterparts,  each of which  when so
executed shall be deemed to be an original and all of which taken together shall
constitute  one and the same  agreement.  (h)  Headings.  The  headings  in this
Agreement are for convenience of reference only and shall not limit or otherwise
affect the meaning  hereof.  (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED
BY AND  CONSTRUED IN  ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO CONFLICT OF LAWS PROVISIONS.  (j) Severability.  In the event that any
one or more of the provisions  contained herein,  or the application  thereof in
any  circumstance,  is held  invalid,  illegal or  unenforceable,  the validity,
legality and  enforceability of any such provision in every other respect and of
the  remaining  provisions  contained  herein  shall not be affected or impaired
thereby.

         This Warrant  Registration  Rights Agreement (the  "Agreement") is made
and entered into as of March 2, 1999, by and among Waste Systems  International,
Inc., a Delaware corporation (the "Issuer"),  the subsidiaries of the Issuer and
First  Albany  Corporation  (the  "Initial  Purchaser"),  which  have  agreed to
purchase the  Warrants of the Issuer  issued  pursuant to the Warrant  Agreement
(the  "Warrant  Agreement")  between the Issuer and IBJ  Whitehall  Bank & Trust
Company, a New York banking corporation, as warrant agent (the "Warrant Agent").

         The Warrants are being issued and sold in connection  with the offering
by the Issuer of 10,000 Units,  each consisting of (i) $10,000  principal amount
at  maturity of 11 1/2%  Senior  Notes due 2006 (the  "Notes") of the Issuer and

<PAGE>

2.    HOLDERS

         A  Person  is  deemed  to be a  holder  of  Registrable  Securities  (a
"Holder")   whenever  such  Person  is  the  holder  of  record  of  Registrable
Securities.

3.    SHELF REGISTRATION

(a) Shelf Registration.  The Issuer shall prepare and cause to be filed with the
Commission  on or before the date 180 days after the  Closing  Date  pursuant to
Rule 415 under the Securities Act a  Registration  Statement on the  appropriate
form relating to resales of  Registrable  Securities by the Holders  thereof and
the  registration  of the  issuance of the Warrant  Shares upon  exercise of the
Warrants.  The  Issuer  shall  use its  reasonable  best  efforts  to cause  the
Registration  Statement to be declared  effective by the Commission on or before
240 days after the Closing Date.

         To the extent  necessary to ensure that the  Registration  Statement is
available for sales of Registrable Securities by the Holders thereof entitled to
the benefit of this  Section  3(a),  the Issuer  shall use its  reasonable  best
efforts  to keep  any  Registration  Statement  required  by this  Section  3(a)
continuously  effective,  supplemented,  amended  and current as required by and
subject to the  provisions  of Section  4(a) hereof and in  conformity  with the
requirements of this Agreement,  the Securities Act and the policies,  rules and
regulations of the Commission as announced from time to time,  until the earlier
of (i) the time when the  Registrable  Securities  covered  by the  Registration
Statement can be sold pursuant to Rule 144 under the  Securities Act without any
limitations  under  clauses (c), (e), (f) and (h) of Rule 144 and (ii) two years
from the Closing Date.  Notwithstanding  the foregoing,  the Issuer shall not be
required  to  amend  or  supplement  the  Registration  Statement,  any  related
prospectus or any document  incorporated  therein by reference,  for a period (a
"Black Out Period") not to exceed,  for so long as this  Agreement is in effect,
an  aggregate of 30 days in any  calendar  year,  in the event that (i) an event
occurs and is continuing as a result of which the  Registration  Statement,  any
related  prospectus  or any document  incorporated  therein by reference as then
amended or supplemented  would, in the Issuer's good faith judgment,  contain an
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading,  and (ii)(A) the Issuer  determines in its
good faith  judgment that the disclosure of such event at such time would have a
material  adverse effect on the business,  operations or prospects of the Issuer
or (B) the disclosure otherwise relates to a material business transaction which
has not yet been publicly disclosed.

(b) Liquidated Damages. In the event that either (i) the Registration  Statement
referred to in subsection (a) above is not filed with the Commission on or prior
to the 180th  calendar day following the Closing  Date,  (ii) such  Registration
Statement  is not  declared  effective  on or prior to the  240th  calendar  day
following  the Closing  Date or (iii) the  Registration  Statement  ceases to be
effective at any time prior to the earlier of (A) the time when the  Registrable
Securities  covered by the  Registration  Statement can be sold pursuant to Rule
144 under the Securities Act without any limitations under clauses (c), (e), (f)
and (h) of Rule 144 and (B) two years from the  Closing  Date (each such event a
"Registration  Default"),  then the per annum  interest  rate borne by the Notes
shall be increased by 0.50%  immediately  following such  Registration  Default.
Upon the  filing  of the  Registration  Statement  or the  effectiveness  of the
Registration Statement, as the case may be, the interest rate borne by the Notes
from the  date of such  filing  or  effectiveness,  as the case may be,  will be
reduced to the otherwise  applicable  interest  rate set forth above;  provided,
however,  that,  if after such  reduction in interest  rate,  a different  event
specified in clause (i),  (ii),  or (iii) above  occurs,  the interest  rate may
again be  increased  pursuant  to the  foregoing  provisions.  If an  event  has
occurred and is continuing as a result of which the Registration Statement would
be required to be amended or  supplemented  or which would  otherwise  cause the
Registration  Statement not to be effective and usable for resale of Registrable
Securities  during the period required by this Agreement,  pursuant to which the
Issuer has issued a Blackout Notice as provided in Section 4(b) hereof,  and the
aggregate  number  of days in any  calendar  year for  which  all such  Blackout
Notices are issued or required to be issued  exceeds 30 days,  then the interest
rate borne by the Notes will be increased by 0.50% per annum  following the date
that such Registration  Statement ceases to be usable beyond the Blackout Period
permitted above.  Upon the Issuer  declaring that the Registration  Statement is
usable  after the interest  rate has been  increased  pursuant to the  preceding
sentence,  the interest rate borne by the Notes will be reduced to the otherwise
applicable  interest  rate if the Issuer is  otherwise in  compliance  with this
Section 3(b),  provided,  however,  that if after any such reduction in interest
rate the  Registration  Statement  again  ceases to be usable  beyond the period
permitted  above within the same calendar  year, the interest rate will again be
increased and thereafter reduced pursuant to the foregoing provisions.

         Notwithstanding  the  foregoing,  in no event shall the  interest  rate
borne by the Notes be increased pursuant to this Section 3(b) or Section 2(e) of
the Note  Registration  Rights Agreement by an amount which exceeds an aggregate
of 0.50% per annum  above  the  otherwise  applicable  per annum  interest  rate
determined without regard to both such provisions.

(c)  Provision  by  Holders  of  Certain  Information  in  Connection  with  the
Registration  Statement.  No Holder of Registrable Securities may include any of
its Registrable  Securities for resale in any Registration Statement pursuant to
this Agreement  unless and until such Holder furnishes to the Issuer in writing,
within 20 days after receipt of a request therefor, the information specified in
Item 507 or 508 of Regulation S-K, as applicable,  of the Securities Act for use
in connection  with any  Registration  Statement or  Prospectus  or  preliminary
Prospectus  included  therein.  Each selling  Holder agrees to promptly  furnish
additional information required to be disclosed in order to make the information
previously furnished to the Issuer by such Holder not materially misleading.  No
such  information  shall be required  with  respect to the  registration  of the
issuance of the Warrant Shares upon exercise of the Warrants.

4.    REGISTRATION PROCEDURES

         (a)       Procedures.  In connection with the Registration  Statement 
and any related Prospectus  required by this Agreement, the Issuer shall:

                  (i)  use  its   reasonable   best   efforts  to  effect   such
         registration  to permit the sale of the  Registrable  Securities  being
         sold in accordance  with the intended method or methods of distribution
         thereof  (as  indicated  in the  information  furnished  to the  Issuer
         pursuant to Section 3(c) hereof),  and pursuant thereto the Issuer will
         prepare and file with the Commission a Registration  Statement relating
         to the  registration on any appropriate  form under the Securities Act,
         which  form  shall  be  available  for  the  sale  of  the  Registrable
         Securities  in  accordance  with the  intended  method  or  methods  of
         distribution   thereof   within  the  time  periods  and  otherwise  in
         accordance with the provisions hereof;

                  (ii) use its reasonable best efforts to keep such Registration
         Statement  continuously  effective and provide all requisite  financial
         statements  for the period  specified  in Section 3 of this  Agreement.
         Upon the occurrence of any event that would cause any such Registration
         Statement or the Prospectus  contained therein (A) to contain an untrue
         statement of 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  or (B) not to be effective  and
         usable for resale of Registrable  Securities during the period required
         by this  Agreement,  the Issuer shall,  subject to Section  3(a),  file
         promptly an appropriate  amendment to such Registration  Statement or a
         supplement to the Prospectus,  as applicable,  curing such defect, and,
         in the case of an amendment,  use its reasonable  best efforts to cause
         such amendment to be declared effective as soon as practicable;

                  (iii) prepare and file with the Commission such amendments and
         post-effective  amendments to the applicable  Registration Statement as
         may be necessary to keep such Registration  Statement effective for the
         applicable  period set forth in Section 3; cause the  Prospectus  to be
         supplemented  by  any  required  Prospectus   supplement,   and  as  so
         supplemented to be filed pursuant to Rule 424 under the Securities Act,
         and to comply fully with Rules 424, 430A and 462, as applicable,  under
         the Securities  Act in a timely manner;  and comply with the provisions
         of the Securities Act with respect to the disposition of all securities
         covered by such Registration  Statement during the applicable period in
         accordance  with the intended  method or methods of distribution by the
         sellers thereof set forth in such Registration  Statement or supplement
         to the Prospectus;

                  (iv) advise the Initial  Purchaser  promptly and, if requested
         by the Initial Purchaser,  confirm such advice in writing, (A) when the
         Prospectus or any Prospectus supplement or post-effective amendment has
         been filed, and, with respect to any applicable  Registration Statement
         or any  post-effective  amendment  thereto,  when the  same has  become
         effective,  (B) of any request by the  Commission for amendments to the
         Registration  Statement or amendments or  supplements to the Prospectus
         or for additional  information relating thereto, (C) of the issuance by
         the Commission of any stop order  suspending the  effectiveness  of the
         Registration Statement under the Securities Act or of the suspension by
         any state securities commission of the qualification of the Registrable
         Securities for offering or sale in any jurisdiction,  or the initiation
         of any  proceeding  for any of the preceding  purposes,  and (D) of the
         existence  of any fact or the  happening  of any event  that  makes any
         statement of a material fact made in the  Registration  Statement,  the
         Prospectus,  any  amendment  or  supplement  thereto  or  any  document
         incorporated by reference  therein untrue,  or that requires the making
         of any additions to or changes in the  Registration  Statement in order
         to make the  statements  therein not  misleading,  or that requires the
         making of any  additions  to or changes in the  Prospectus  in order to
         make the statements  therein,  in the light of the circumstances  under
         which they were made,  not  misleading.  If at any time the  Commission
         shall  issue  any  stop  order  suspending  the  effectiveness  of  the
         Registration  Statement,  or any state  securities  commission or other
         regulatory  authority shall issue an order suspending the qualification
         or exemption from  qualification  of the Registrable  Securities  under
         state  securities or Blue Sky laws, the Issuer shall use its reasonable
         best efforts to obtain the  withdrawal  or lifting of such order at the
         earliest possible time;

                  (v) subject to Section  4(a)(ii) and Section  3(b) hereof,  if
         any fact or event  contemplated  by Section  4(a)(iv)(D)  hereof  shall
         exist  or  have  occurred,   prepare  a  supplement  or  post-effective
         amendment to the  Registration  Statement or related  Prospectus or any
         document  incorporated  therein by reference or file any other required
         document  so  that,  as  thereafter  delivered  to  the  purchasers  of
         Registrable  Securities,  the  Prospectus  will not  contain  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;


<PAGE>

                  (vi) furnish to the Initial Purchaser,  before filing with the
         Commission,  copies of any  Registration  Statement  or any  Prospectus
         included   therein  or  any  amendments  or  supplements  to  any  such
         Registration   Statement  or   Prospectus   (including   all  documents
         incorporated by reference after the initial filing of such Registration
         Statement),  which  documents will be subject to the review and comment
         of such Persons,  if any, for a period of at least five Business  Days,
         and the  Issuer  will  not  file any  such  Registration  Statement  or
         Prospectus  or any  amendment or  supplement  to any such  Registration
         Statement or Prospectus  (including all such documents  incorporated by
         reference)  to which the  Initial  Purchaser  shall  reasonably  object
         within  five  Business  Days after the  receipt  thereof.  The  Initial
         Purchaser shall be deemed to have reasonably objected to such filing if
         such Registration Statement,  amendment,  Prospectus or supplement,  as
         applicable,  as proposed to be filed, contains an untrue statement of a
         material fact or omits to state any material fact necessary to make the
         statements  therein, in the light of the circumstances under which they
         were  made,  not  misleading  or fails to  comply  with the  applicable
         requirements of the Securities Act;

                  (vii)  promptly prior to the filing of any document that is to
         be  incorporated   by  reference  into  a  Registration   Statement  or
         Prospectus,  provide copies of such document to the Initial  Purchaser,
         make the Issuer's  representatives  available  for  discussion  of such
         document and other  customary due diligence  matters,  and include such
         information in such document prior to the filing thereof as the Initial
         Purchaser may reasonably request;

                  (viii) make available,  at reasonable times, for inspection by
         the Initial  Purchaser and any attorney or  accountant  retained by the
         Initial Purchaser, all financial and other records, pertinent corporate
         documents of the Issuer and cause the Issuer's officers,  directors and
         employees to supply all information reasonably requested by the Initial
         Purchaser,  attorney or accountant in connection with such Registration
         Statement or any  post-effective  amendment  thereto  subsequent to the
         filing thereof and prior to its effectiveness;

                  (ix) if requested by the Initial  Purchaser,  promptly include
         in the Registration  Statement or Prospectus,  pursuant to a supplement
         or  post-effective  amendment if  necessary,  such  information  as the
         Initial  Purchaser may  reasonably  request to have  included  therein,
         including,  without  limitation,  information  relating to the "Plan of
         Distribution"  of  the  Registrable  Securities  and  the  use  of  the
         Registration Statement or Prospectus for market-making activities;  and
         make  all   required   filings  of  such   Prospectus   supplement   or
         post-effective  amendment  as soon as  practicable  after the Issuer is
         notified of the matters to be included in such Prospectus supplement or
         post-effective amendment;

                  (x)  furnish to the  Initial  Purchaser  and each  Holder upon
         request,  without  charge,  at  least  one  copy  of  the  Registration
         Statement,  as first filed with the  Commission,  and of each amendment
         thereto,  including all documents incorporated by reference therein and
         all exhibits (including exhibits incorporated therein by reference);

                  (xi) deliver to the Initial Purchaser and each Holder, without
         charge,  as many copies of the Prospectus  (including each  preliminary
         prospectus)  and any  amendment  or  supplement  thereto as the Initial
         Purchaser  or such Holder  reasonably  may request;  the Issuer  hereby
         consents to the use (in accordance with law and subject to Section 4(b)
         hereof) of the  Prospectus  and any amendment or supplement  thereto by
         each selling Person in connection with the offering and the sale of the
         Registrable  Securities  covered by the  Prospectus or any amendment or
         supplement  thereto  and all  market-making  activities  of the Initial
         Purchaser, as the case may be;

                  (xii) prior to any public offering of Registrable  Securities,
         cooperate with the selling Holders and their counsel in connection with
         the registration and qualification of the Registrable  Securities under
         the  securities or Blue Sky laws of such  jurisdictions  as the selling
         Holders may  request and do any and all other acts or things  necessary
         or advisable to enable the  disposition  in such  jurisdictions  of the
         Registrable   Securities   covered  by  the   applicable   Registration
         Statement;  provided  that the Issuer shall not be required to register
         or qualify as a foreign corporation where it is not now so qualified or
         to take any action  that would  subject it to the service of process in
         suits  or to  taxation,  other  than  as to  matters  and  transactions
         relating to the Registration Statement, in any jurisdiction where it is
         not now so subject;

                  (xiii) in connection  with any sale of Registrable  Securities
         that  will  result  in such  securities  no  longer  being  Registrable
         Securities,  cooperate  with  the  Holders  to  facilitate  the  timely
         preparation  and  delivery  of  certificates  representing  Registrable
         Securities to be sold and not bearing any restrictive  legends;  and to
         register such  Registrable  Securities in such  denominations  and such
         names as the selling  Holders may  request at least two  Business  Days
         prior to such sale of Registrable Securities;

                  (xiv) use its reasonable best efforts to cause the disposition
         of the Registrable  Securities covered by the Registration Statement to
         be registered with or approved by such other  governmental  agencies or
         authorities as may be necessary to enable the seller or sellers thereof
         to consummate the disposition of such Registrable  Securities,  subject
         to the proviso contained in clause (xiii) above;


<PAGE>

                  (xv) provide a CUSIP number for all Registrable Securities not
         later than the effective date of a Registration Statement covering such
         Registrable  Securities  and  provide the  Warrant  Agent with  printed
         certificates  for  the  Registrable  Securities  which  are  in a  form
         eligible for deposit with The Depository Trust Company;

                  (xvi) otherwise use its reasonable best efforts to comply with
         all  applicable  rules  and  regulations  of the  Commission,  and make
         generally  available  to  its  security  holders  with  regard  to  any
         applicable  Registration  Statement,  as soon as  practicable  (but not
         sooner than the filing  deadline of the last quarterly  report included
         therein), a consolidated earnings statement meeting the requirements of
         Rule 158 (which need not be  audited)  covering a  twelve-month  period
         beginning  after the effective date of the  Registration  Statement (as
         such term is defined in Rule 158(c) under the Securities Act); and

                  (xvii)  provide  promptly  to  the  Initial  Purchaser,   upon
         request,  each  document  filed  with the  Commission  pursuant  to the
         requirements of Section 13 or Section 15(d) of the Exchange Act.

         (b)  Restrictions  on Holders.  Each Holder agrees by  acquisition of a
Registrable  Security and the Initial  Purchaser agree that, upon receipt of the
notice from the Issuer of the  commencement of a Black Out Period (in each case,
a "Black Out Notice"),  such Person will  forthwith  discontinue  disposition of
Registrable  Securities pursuant to the applicable  Registration Statement until
such Person is advised in writing by the Issuer of the  termination of the Black
Out Period.  Each Person receiving a Black Out Notice hereby agrees that it will
either (i) destroy any Prospectuses,  other than permanent file copies,  then in
such  Person's  possession  which have been  replaced  by the  Issuer  with more
recently  dated  Prospectuses  or (ii)  deliver to the  Issuer (at the  Issuer's
expense) all copies,  other than  permanent  file copies,  then in such Person's
possession of the  Prospectus  covering  such  Registrable  Securities  that was
current at the time of receipt of the Black Out Notice.

5.    REGISTRATION EXPENSES

         All expenses incident to the Issuer's performance of or compliance with
this Agreement will be borne by the Issuer, regardless of whether a Registration
Statement becomes effective, including, without limitation: (i) all registration
and filing fees and  expenses;  (ii) all fees and  expenses of  compliance  with
federal  securities and state Blue Sky or securities laws; (iii) all expenses of
printing (including printing Prospectuses  (whether for sales,  market-making or
otherwise),  messenger and delivery  services and  telephone;  (iv) all fees and
disbursements of counsel for the Issuer;  (v) all application and filing fees in
connection with listing the Warrant Shares on a national  securities exchange or
automated  quotation  system pursuant to the requirements  hereof;  and (vi) all
fees and disbursements of independent certified public accountants of the Issuer
(including the expenses of any special audit and comfort letters  required by or
incident to such performance).

         The Issuer will, in any event, bear its internal  expenses  (including,
without  limitation,  all salaries  and  expenses of its officers and  employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and  expenses of any Person,  including  special  experts,  retained by the
Issuer.

6.    INDEMNIFICATION AND CONTRIBUTION

         (a) The Issuer and each of its  subsidiaries,  jointly  and  severally,
agree to indemnify and hold  harmless  each Holder and each person,  if any, who
controls any Holder  within the meaning of Section 15 of the  Securities  Act or
Section  20  of  the  Exchange  Act  against  any  losses,  claims,  damages  or
liabilities,  joint or several,  to which such Holder or such controlling person
may become  subject  under the  Securities  Act, the Exchange Act or  otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof) arise out of or are based upon:

                           (i)       any untrue  statement or alleged untrue 
         statement made by the Issuer or any of its subsidiaries of any material
         fact contained in the Offering Memorandum,

                           (ii) any untrue statement or alleged untrue statement
         of any material  fact  contained in (A) any  Registration  Statement or
         Prospectus  or  any   amendment  or  supplement   thereto  or  (B)  any
         application or other document,  or any amendment or supplement thereto,
         executed by the Issuer or based upon written  information  furnished by
         or on  behalf  of the  Issuer  filed  in any  jurisdiction  in order to
         qualify the  Registrable  Securities  under the  securities or blue sky
         laws thereof or filed with the Commission or any securities association
         or securities exchange (each an "Application"),

                           (iii) the  omission  or alleged  omission to state in
         any Registration Statement or Prospectus or any amendment or supplement
         thereto,  or any  Application  a material fact required to be stated in
         such Registration Statement or necessary to make the statements in such
         Registration   Statement,   at  the  time  it  became  effective,   not
         misleading,  or  required  to be  stated  in  such  Prospectus  or  any
         supplement or amendment  thereto or necessary to make the statements in
         such Prospectus, at the date thereof, in the light of the circumstances
         under which they were made, not misleading,

<PAGE>



and will reimburse,  as incurred,  each Holder and each such controlling  person
for any  legal or other  expenses  reasonably  incurred  by such  Holder or such
controlling  person in  connection  with  investigating,  defending  against  or
appearing as a  third-party  witness in  connection  with any such loss,  claim,
damage, liability or action; provided,  however, that the Issuer and each of its
subsidiaries,  jointly and severally, will not be liable in any such case to the
extent that any such loss, claim,  damage or liability arises out of or is based
upon any untrue  statement  or alleged  untrue  statement or omission or alleged
omission  made in any  Registration  Statement or Prospectus or any amendment or
supplement  thereto or any  Application in reliance upon and in conformity  with
written  information  relating  to any  Holder  furnished  to the Issuer by such
Holder specifically for use therein. The foregoing  indemnification with respect
to any preliminary Prospectus or final Prospectus shall not inure to the benefit
of any Holder (or to the benefit of any person  controlling  such Holder) if the
person asserting any such losses, claims,  damages,  liabilities or expenses was
not sent or delivered a copy of the final Prospectus (or the final Prospectus as
amended or supplemented) at or prior to the written  confirmation of the sale of
Registrable Securities to such person and if the untrue statement or omission of
a material fact  contained in such  preliminary  Prospectus was corrected in the
final  Prospectus (or the final  Prospectus as amended or  supplemented)  unless
such corrected  final  Prospectus was not sent or delivered  because the Company
failed to timely  provide such Holder with  sufficient  copies of such corrected
final Prospectus.  This indemnity agreement will be in addition to any liability
which the  Issuer  and each of its  subsidiaries,  jointly  and  severally,  may
otherwise  have to any Holder or to any person who controls  such Holder  within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act.

         (b) Each Holder,  severally and not jointly,  agrees,  by acquiring any
Registrable  Securities,  to indemnify and hold harmless the Issuer, each of its
directors,  each of its executive officers and each person, if any, who controls
the Issuer within the meaning of Section 15 of the  Securities Act or Section 20
of the Exchange Act against any losses,  claims, damages or liabilities to which
the Issuer, any such director,  officer or controlling person may become subject
under the Securities Act or otherwise,  insofar as such losses,  claims, damages
or  liabilities  (or actions in respect  thereof) arise out of or are based upon
(i) any untrue  statement  or alleged  untrue  statement  of any  material  fact
contained  in any  Registration  Statement  or  Prospectus  or any  amendment or
supplement  thereto or any Application or (ii) the omission or alleged  omission
to state  in any  Registration  Statement  or  Prospectus  or any  amendment  or
supplement  thereto, or any Application a material fact required to be stated in
such  Registration  Statement  or  necessary  to  make  the  statements  in such
Registration  Statement,  at the time it became  effective,  not misleading,  or
required to be stated in such Prospectus or any supplement or amendment  thereto
or necessary to make the statements in such Prospectus,  at the date thereof, in
the light of the  circumstances  under which they were made, not misleading,  in
each case to the extent,  but only to the extent,  that such untrue statement or
alleged  untrue  statement or omission or alleged  omission was made in reliance
upon and in conformity with written information relating to any Holder furnished
to the Issuer by such Holder  specifically for use therein;  and, subject to the
limitation set forth  immediately  preceding  this clause,  will  reimburse,  as
incurred,  any legal or other expenses  reasonably incurred by the Issuer or any
such director, officer or controlling person in connection with investigating or
defending  any such  loss,  claim,  damage,  liability  or any action in respect
thereof. In no event shall any Holder, its directors, officers or any person who
controls  such Holder be liable or  responsible  for any amount in excess of the
amount by which the total  amount  received by such  Holder with  respect to its
sale of Registrable  Securities pursuant to a Registration Statement exceeds (i)
the amount  paid by such  Holder for such  Registrable  Securities  and (ii) the
amount of any damages that such Holder,  its  directors,  officers or any Person
who controls  such Holder has  otherwise  been required to pay by reason of such
untrue or  alleged  untrue  statement  or  omission  or alleged  omission.  This
indemnity  agreement will be in addition to any liability  which such Holder may
otherwise have.

         (c) Promptly after receipt by an indemnified party under this Section 6
of notice of the commencement of any action,  such indemnified  party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party of the commencement thereof in writing;
but the  omission so to notify the  indemnifying  party will not relieve it from
any liability  which it may have to any  indemnified  party otherwise than under
this  Section 6. In case any such  action is  brought  against  any  indemnified
party, and it notifies the indemnifying party of the commencement  thereof,  the
indemnifying  party will be entitled to  participate  therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly  notified,
to assume and control the defense  thereof,  with counsel  satisfactory  to such
indemnified party; provided,  however, that if the defendants in any such action
include  both  the  indemnified  party  and  the  indemnifying   party  and  the
indemnified party shall have reasonably  concluded that there may be one or more
legal  defenses  available  to it and/or  other  indemnified  parties  which are
different from or additional to those available to the  indemnifying  party, the
indemnifying party shall not have the right to direct the defense of such action
on behalf of such  indemnified  party or parties and such  indemnified  party or
parties shall have the right to select separate counsel to defend such action on
behalf of such indemnified party or parties.  After notice from the indemnifying
party to such  indemnified  party of its election to assume the defense  thereof
and  approval  by such  indemnified  party of counsel  appointed  to defend such
action,  the  indemnifying  party will not be liable to such  indemnified  party
under this  Section 6 for any legal or other  expenses,  other  than  reasonable
costs of  investigation,  subsequently  incurred  by such  indemnified  party in
connection with the defense thereof, unless (i) the indemnified party shall have

<PAGE>


employed  separate  counsel in accordance with the proviso to the next preceding
sentence (it being understood,  however, that in connection with such action the
indemnifying  party  shall  not be  liable  for the  expenses  of more  than one
separate  counsel (in  addition to local  counsel) in any one action or separate
but substantially  similar actions in the same  jurisdiction  arising out of the
same general allegations or circumstances, designated by such Holder in the case
of paragraph (a) of this Section 6,  representing the indemnified  parties under
such  paragraph  (a) who are  parties  to such  action or  actions)  or (ii) the
indemnifying  party  does  not  promptly  retain  counsel  satisfactory  to  the
indemnified party or (iii) the indemnifying  party has authorized the employment
of counsel for the indemnified  party at the expense of the indemnifying  party.
After such notice from the  indemnifying  party to such  indemnified  party, the
indemnifying  party  will  not be  liable  for the  costs  and  expenses  of any
settlement of such action effected by such indemnified party without the consent
of the  indemnifying  party. No  indemnifying  party shall (A) without the prior
written  consent  of  the  indemnified  parties  (which  consent  shall  not  be
unreasonably  withheld)  settle or  compromise  or  consent  to the entry of any
judgment  with  respect to any  pending or  threatened  claim,  action,  suit or
proceeding in respect of which  indemnification  or  contribution  may be sought
hereunder  (whether  or not the  indemnified  parties  are  actual or  potential
parties to such claim or action) unless such  settlement,  compromise or consent
(1)  includes  an  unconditional  release  of each  indemnified  party  from all
liability arising out of such claim, action, suit or proceeding and (2) does not
include a statement as to or an admission of fault,  culpability or a failure to
act by or on  account  of any  indemnified  party,  or (B)  be  liable  for  any
settlement  of any such  action  effected  without its  written  consent  (which
consent shall not be unreasonably withheld),  but if settled with the consent of
the  indemnifying  party or if there be a final judgment of the plaintiff in any
such action,  the  indemnifying  party agrees to indemnify and hold harmless any
indemnified  party  from and  against  any loss or  liability  by reason of such
settlement or judgment.

         (d) In circumstances in which the indemnity  agreement  provided for in
the preceding  paragraphs of this Section 6 is unavailable or insufficient,  for
any  reason,  to hold  harmless an  indemnified  party in respect of any losses,
claims,   damages  or  liabilities  (or  actions  in  respect   thereof),   each
indemnifying  party,  in order to provide for just and  equitable  contribution,
shall  contribute to the amount paid or payable by such  indemnified  party as a
result of such losses,  claims,  damages or  liabilities  (or actions in respect
thereof)  in such  proportion  as is  appropriate  to reflect  (i) the  relative
benefits  received by the indemnifying  party or parties on the one hand and the
indemnified  party on the other from the offering of the  Securities  or (ii) if
the  allocation  provided  by the  foregoing  clause  (i) is  not  permitted  by
applicable  law, not only such relative  benefits but also the relative fault of
the indemnifying  party or parties on the one hand and the indemnified  party on
the other in connection  with the statements or omissions or alleged  statements
or omissions that resulted in such losses,  claims,  damages or liabilities  (or
actions  in  respect  thereof),   as  well  as  any  other  relevant   equitable
considerations.  The  relative  fault  of the  parties  shall be  determined  by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged  omission to state a material fact
relates to  information  supplied  by the Issuer or such  Holder,  the  parties'
relative intents, knowledge, access to information and opportunity to correct or
prevent  such  statement  or omission,  and any other  equitable  considerations
appropriate in the  circumstances.  The amount paid or payable by an indemnified
party as a result of the  losses,  claims,  damages,  liabilities  or  judgments
referred  to above shall be deemed to include,  subject to the  limitations  set
forth in Section 6(b), any legal or other fees or expenses  reasonably  incurred
by such  indemnified  party in connection  with  investigating  or defending any
matter,  including any action that could have given rise to such losses, claims,
damages, liabilities or judgments.

         The Issuer,  each of its  subsidiaries  and each  Holder  agree that it
would  not be  just  and  equitable  if the  amount  of such  contribution  were
determined  by pro  rata or per  capita  allocation  (even if the  Holders  were
treated as one entity for such  purpose)  or by any other  method of  allocation
that does not take into account the equitable  considerations  referred to above
in this paragraph  (d).  Notwithstanding  any other  provision of this paragraph
(d), no Holder shall be obligated to make  contributions  hereunder  that in the
aggregate  exceed the total public offering price of the Registrable  Securities
purchased by such Holder under this Agreement,  less the aggregate amount of any
damages that such Holder has  otherwise  been  required to pay in respect of the
same or any  substantially  similar  claim,  and no person  guilty of fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation. The Holders' obligations to contribute pursuant to
this Section are several in proportion  to the  respective  principal  amount of
Registrable Securities held by each Holder hereunder and not joint. For purposes
of this  paragraph  (d),  each person,  if any, who controls a Holder within the
meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange Act
shall have the same rights to contribution as such Holder,  and each director of
the Issuer, each officer of the Issuer who signed the Registration Statement and
each person, if any, who controls the Issuer within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act, shall have the same rights
to contribution as the Issuer.

         (e) The Issuer and each of its  subsidiaries  agree that the  indemnity
and  contribution  provisions  of this  Section  6 shall  apply  to the  Initial
Purchaser  to the same  extent,  on the same  conditions,  as they  apply to the
Holders.

         (f) The  parties to this  Agreement  hereby  acknowledge  that they are
sophisticated  business  persons  who were  represented  by  counsel  during the
negotiations  regarding the  provisions of this  Agreement,  including,  without
limitation,  the provisions of this Section 6, and are fully informed  regarding
said provisions.  They further acknowledge that the provisions of this Section 6
fairly  allocate the risks in light of the ability of the parties to investigate
the Issuer and its business in order to assure that adequate  disclosure is made
in the Registration Statement as required by the Securities Act. The parties are
advised that federal or state policy,  as  interpreted  by the courts in certain
jurisdictions,  may be contrary to certain provisions of this Section 6, and the
parties  hereto hereby  expressly  waive and  relinquish any right or ability to
assert  such  public  policy as a defense to a claim  under  this  Section 6 and
further agree not to attempt to assert any such defense.

7.    RULE 144

         The  Issuer  agrees  with  each  Holder,  so  long  as any  Registrable
Securities  remain  outstanding  and  during  any  period in which the Issuer is
subject to Section 13 or 15(d) of the Exchange Act, to make all filings required
thereby  in a timely  manner  in order to  permit  resales  of such  Registrable
Securities pursuant to Rule 144.

8.    MISCELLANEOUS

         (a) Remedies.  The Issuer  acknowledges  and agrees that any failure by
the Issuer to comply with its  obligations  under Section 3 hereof may result in
material  irreparable  injury to the Initial  Purchaser or the Holders for which
there is no  adequate  remedy at law,  that it will not be  possible  to measure
damages for such injuries  precisely and that, in the event of any such failure,
the Initial Purchaser or any Holder may obtain such relief as may be required to
specifically enforce the Issuer's obligations under Section 3 hereof. The Issuer
further agrees to waive the defense in any action for specific  performance that
a remedy at law would be adequate.

         (b) No  Inconsistent  Agreements.  The Issuer will not, on or after the
date of this Agreement,  enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise  conflicts  with the  provisions  hereof.  The  rights  granted to the
Holders  hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Issuer's securities under any agreement
in effect on the date hereof.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the  provisions  hereof may not be given  unless (i) in the case of this Section
8(c), the Issuer has obtained the written  consent of Holders of all outstanding
Registrable Securities, and (ii) in the case of all other provisions hereof, the
Issuer has  obtained  the  written  consent  of  Holders  of a  majority  of the
outstanding principal amount of Registrable  Securities  (excluding  Registrable
Securities  held  by the  Issuer,  any  Subsidiary  Guarantor,  or any of  their
respective Affiliates);  provided that this Agreement may be amended without the
consent of any Holder pursuant to Section 22 of the Warrant Agreement.

         (d)  Third  Party  Beneficiary.   The  Holders  shall  be  third  party
beneficiaries  to the  agreements  granting  rights to  Holders  made  hereunder
between the Issuer,  on the one hand,  and the Initial  Purchaser,  on the other
hand, and shall have the right to enforce such agreements directly to the extent
they may deem such  enforcement  necessary or advisable to protect its rights or
the rights of Holders hereunder.

         (e)  Notices.  All notices  and other  communications  provided  for or
permitted hereunder shall be made in writing by hand-delivery,  first-class mail
(registered or certified,  return receipt requested),  telex, telecopier, or air

         (f) Successors and Assigns.  This Agreement  shall inure to the benefit
of and be  binding  upon the  successors  and  assigns  of each of the  parties,
including,  without limitation,  and without the need for an express assignment,
subsequent  Holders;  provided that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Registrable Securities in violation
of the terms hereof or of the Purchase  Agreement or the Warrant  Agreement.  If
any transferee of any Holder shall acquire Registrable Securities in any manner,
whether by operation of law or otherwise,  such Registrable  Securities shall be
held  subject to all of the terms of this  Agreement,  and by taking and holding
such  Registrable  Securities such Person shall be  conclusively  deemed to have
agreed to be bound by and to  perform  all of the terms and  provisions  of this
Agreement, including the restrictions on resale set forth in this Agreement and,
if  applicable,  the  Purchase  Agreement,  and such Person shall be entitled to
receive the benefits hereof.

         (g)  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

         (h)       Headings. The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

         (i)       Governing  Law. THIS  AGREEMENT  SHALL BE GOVERNED BY AND 
CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD 
TO THE CONFLICT OF LAW RULES THEREOF.

         (j)  Severability.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held
invalid, illegal or unenforceable,  the validity, legality and enforceability of
any such  provision  in every  other  respect  and of the  remaining  provisions
contained herein shall not be affected or impaired thereby.

         (k) Entire  Agreement.  This  Agreement is intended by the parties as a
final  expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the  subject  matter  contained  herein.  There are no  restrictions,  promises,
warranties  or  undertakings,  other than those set forth or  referred to herein

   WASTE SYSTEMS INTERNATIONAL, INC. ANNOUNCES CLOSING OF $100 MILLION SENIOR 
                      UNSECURED NOTES OFFERING, 500,000
                              SHARE BUYBACK
                                  AND
                      TWELVE TUCK-IN ACQUISITIONS

Lexington,  Massachusetts,  March 2, 1999 - Waste  Systems  International,  Inc.
("WSI")  (NASDAQ:  WSII),  an integrated  non-hazardous  solid waste  management
company,  announced  today  that it has  completed  the sale of $100  million in
principal  amount of seven-year  11.5% Senior  Unsecured Notes through a private
placement with  institutional  investors.  The issuance of the Senior  Unsecured
Notes has been structured to allow  secondary  market trading under Rule 144A of
the Act of 1933.  The net  proceeds of the  offering  will be used to complete a
buyback  of  500,000  shares  of  Common  Stock,   finance  pending  and  future
acquisitions,  repayment of  outstanding  debt,  as well as for general  working
capital purposes.

 "This  financing  allows WSI to continue  pursuing its  aggressive  acquisition
strategy," commented Philip Strauss, WSI's Chairman and Chief Executive Officer.
"Over the last year, WSI has demonstrated its ability to effectively  pursue its
strategy of  acquiring  solid waste assets at prices the Company  believes  will
provide  opportunities  for increased  growth,  profits and cash flow,"  Strauss
added.

The Company also announced that it has closed or signed definitive agreements to
acquire 12 tuck-in collection companies in its Central Pennsylvania, Central New
York and Central  Massachusetts  markets. The combined aggregate annual revenues
of the acquisitions are approximately $7.5 million.

 "These tuck-ins  strengthen our presence in each of the respective  markets and
will help us to  continue  to increase  our  operating  margins and cash flow in
these  regions,"  commented  Philip W.  Strauss,  Chairman  and Chief  Executive
Officer.  "We are very pleased with the results of our acquisitions to date. Our
pipeline of potential acquisitions remains strong," Strauss added.

WSI is an innovative solid waste management  company.  The Company currently has
operations in Vermont,  Central Pennsylvania,  Central Massachusetts and Central

customers.  The Company is also evaluating other  acquisitions and opportunities

Certain matters discussed in the press release, including statements with regard
to acquisition and growth plans, and prospects, are "forward-looking statements"
intended to qualify  for the safe  harbors  from  liability  established  by the
Private Securities Litigation Reform Act of 1995. Forward-looking statements are
inherently uncertain and subject to risks. Such statements should be viewed with
caution.  Among the important  factors that could cause actual results to differ
materially  from those  indicated  by such  forward-looking  statements  are the
Company's  ability  to manage  growth,  a history  of  losses,  the  ability  to
identify,  acquire and integrate acquisition targets,  dependence on management,
the uncertain ability to finance the Company's  growth,  limitations on landfill
permitting and expansion,  geographic concentration,  and the other risk factors
detailed from time to time in the Company's  periodic  reports and  registration
statements filed with the Securities and Exchange Commission.  The Company makes
no commitment to disclose any revisions to  forward-looking  statements,  or any
facts,  events  or  circumstances  after  the date  hereof  that  may bear  upon
forward-looking statements.
