        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


NOTE A.           BASIS OF PRESENTATION
- ---------------------------------------

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. In the opinion of management, all adjustments (consisting
of normal  recurring  accruals  and the  unusual  charges  discussed  in Note B)
necessary for a fair presentation have been included.  Operating results for the
three and nine  month  periods  ended  September  30,  1997 are not  necessarily
indicative of the results that may be expected for the year ending  December 31,
1997.  The  condensed  consolidated  balance sheet at December 31, 1996 has been
derived from audited financial statements at that date. For further information,
refer to the consolidated financial statements and notes thereto included in the
Company's Annual Report on Form 10-K for the year ended December 31, 1996.

Certain  amounts  reported  in  the  prior  year  have  been   reclassified  for
comparative purposes.

In February 1997, the Financial  Accounting Standards Board issued Statement No.
128, Earnings per Share, which will change the method for computing earnings per
share starting in the fourth quarter of 1997. The new method would have resulted
in the same per share amounts in both the 1997 and 1996 periods.

NOTE B.           UNUSUAL CHARGES
- ---------------------------------

In the first quarter of 1996, the Company  initiated a reorganization to improve
productivity  and reduce costs.  The  reorganization  consisted  principally  of
consolidating all the Company's  headquarters  functions in a single office. The
Company's  corporate  headquarters in Stamford,  Connecticut and the Treatment &
Disposal Services segment's headquarters in Horsham, Pennsylvania were closed by
mid-1996  and  their  activities  moved  to  the   International   Mill  Service
headquarters  building,  also  in  Horsham.   Approximately  50  positions  were
eliminated,  mostly in the Treatment & Disposal Services  segment.  To cover the
cost of these and related charges, the Company provided $4.4 million in 1996, of
which $.7 million was provided in the third quarter.

Unusual  charges in 1996 also included  $1.2  million,  of which $.3 million was
provided  in the third  quarter,  to settle the last  disputed  matter  from the
Company's 1993 restructuring.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


NOTE B.           UNUSUAL CHARGES -- Continued
- ----------------------------------------------

The 1996  unusual  charges  amounted to a $.02 per share loss in the quarter and
$.14 per share loss in the nine month period.

The 1997 quarter  includes an unusual charge of $.5 million to provide for costs
to  vacate  an  office as part of the  Company's  further  consolidation  of its
operations.  After taxes,  the 1997 unusual charge  amounted to a $.01 per share
loss in both the quarter and the nine month period.

NOTE C.           SALE OF IMSAMET
- ---------------------------------

In  January  1997  the  Company  sold the  capital  stock of  IMSAMET,  Inc.,  a
wholly-owned  subsidiary that performed  recycling and waste management services
for the aluminum  industry,  for $58 million,  realizing a pre-tax gain of $19.6
million. In the third quarter, a purchase price adjustment increased the pre-tax
gain by $2 million. After deferred income tax charges, the gain amounted to $1.3
million or $.03 per share for the quarter and $9.6 million or $.23 per share for
the nine month period.  The proceeds from the sale were used to repay  revolving
credit  borrowings and expenses  related to the  transaction.  The gain from the
sale in 1997 and IMSAMET's  1996 results have been  classified  as  discontinued
operations.  IMSAMET  revenues  for the 1996 three and nine month  periods  were
$8,723,000 and $27,602,000.

NOTE D.           ALEXANDER MILL SERVICES ACQUISITION
- -----------------------------------------------------

The Company purchased Alexander Mill Services, Inc., a metal reclamation company
serving  the  mini-mill  sector of the steel  industry,  in May 1996.  Pro forma
results of operations, as if this transaction occurred at the beginning of 1996,
are as follows (in thousands, except per share amount):

                                                             September 30, 1996
                                                             ------------------

Pro forma revenues                                               $ 164,571
Pro forma net loss                                                  (4,158)
Pro forma net loss per share                                     $    (.11)

The pro forma  information  is not  necessarily  indicative  of the results that
would have occurred had the transaction taken place at the beginning of 1996.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


NOTE E.           OTHER INFORMATION
- -----------------------------------

On September 30, 1997, the Company issued $50 million of 9 3/4% Senior Notes due
2003, Series B, having  substantially  the same terms as the Company's  existing
$220 million of 9 3/4% Senior  Notes due 2003.  The Company used most of the net
proceeds to pay off the  outstanding  balance on its bank credit  facility.  The
effective  interest  rate  on the  new  Senior  Notes  is  approximately  11.1%,
including  amortization of issuance costs. In conjunction with that transaction,
the borrowing capacity under the bank credit facility was reduced by $15 million
and various financial covenants, requiring the Company to meet certain financial
ratios and tests,  were  modified.  As of September  30,  1997,  $6.6 million of
standby letters of credit and no revolving  credit  borrowings were  outstanding
under this $50 million facility.

During the nine  months  ended  September  30, 1997 and 1996,  the Company  paid
interest of $15 million and $15.7 million.

Current income tax expense  consists of state and foreign  income taxes.  During
the nine months ended  September 30, 1997 and 1996, the Company made cash income
tax  payments,  net of refunds,  of $.9 million  and $.6  million.  In the three
months ended September 30, 1997 and 1996, the Company  recorded $2.1 million and
$1.2  million  of  deferred  federal  income tax  expense to reduce the  benefit
recorded in the first six months of each year, due to lower expected earnings in
each year.

In the third quarter of 1997,  the Company paid $7.9 million and issued  362,319
shares  of  common  stock to  satisfy  obligations,  including  resolution  of a
disputed   matter,   related  to  the  1988   acquisition  of  IU  International
Corporation.

In the first  quarter of 1996,  the Company  retired  236,120  shares of Class G
redeemable preferred stock for $33.1 million, resulting in a $250,000 retirement
gain.

NOTE F.           COMMITMENTS AND CONTINGENCIES
- -----------------------------------------------

As of September 30, 1997,  the Company has  commitments to spend $12 million for
equipment additions and improvements to waste treatment facilities.

At September 30, 1997, the Company was  contingently  liable for $6.6 million of
letters of credit outstanding under its bank credit  agreement,  including  $4.9

million that secure liabilities already reflected in the condensed  consolidated
balance sheet.

To secure  its  obligations  to close its  landfills  and  perform  post-closure
monitoring  and  maintenance  procedures,  the Company must make  payments  into
closure trust funds. Based on current regulations, planned improvements to waste
treatment  facilities  and  permitted  capacity,  such  payments are expected to
amount to approximately $1.7 million in 1997 and $2.7 million in 1998, including
the  reinvestment  of Idaho trust fund  earnings  that the  Company  includes in
interest  income.  Thereafter,  such  payments  are not  expected  to exceed the
reinvestment of trust fund earnings, based on current requirements.

The Company's Ohio and Idaho  facilities hold operating  permits issued by state
and federal environmental  agencies under the Resource Conservation and Recovery
Act, as amended,  that require renewal and  modification  from time to time. The
Company  expects  that it will  obtain the  renewals  and  modifications  to its
permits  that it  requires  to  continue  to provide  landfill  capacity  in its
approved disposal cells well into the next decade.

The Company and its competitors and customers are subject to a complex, evolving
array of  federal,  state  and  local  environmental  laws and  regulations.  In
particular,  such  requirements not only can affect the demand for treatment and
disposal services, but could also require the Company to incur significant costs
for such matters as facility upgrading,  remediation or other corrective action,
facility  closure and  post-closure  maintenance and monitoring.  It is possible
that the future imposition of additional  environmental  compliance requirements
could have a material  adverse effect on the Company's  results of operations or
financial  condition,  but the  Company  is unable to  predict  any such  future
requirements.  The Company believes that the consolidated  financial  statements
appropriately  reflect all  presently-known  compliance costs in accordance with
generally accepted accounting principles.

The  Company  is a party to  litigation  and  proceedings  arising in the normal
course of its present or former  businesses.  In the opinion of management,  the
outcome of such matters will not have a material adverse effect on the Company's
financial condition or results of operations.

         Industrial   Environmental  Services  revenues  increased  slightly  as
compared  to the  1996  second  quarter.  Revenue  improvements,  due to  strong
production at most of the segment's steel industry  customer sites, were largely
offset by a revenue reduction resulting from a strike (settled in mid-August) by
a major steel  industry  customer's  employees.  Treatment  & Disposal  Services
revenues  increased  significantly  in the 1997 third quarter as compared to the
1996 quarter due to a sharp  increase in the volume of electric arc furnace dust
(a hazardous  waste  produced by steel  mini-mills)  stabilized at the Company's
Ohio and Idaho treatment facilities.

         Industrial  Environmental Services gross profit decreased primarily due
to the strike and the temporary impact of changes in manufacturing  practices at
two other customers. Treatment & Disposal Services gross profit increased due to
the increase in electric arc furnace dust disposal volume.

         Selling,  general and administrative  expenses increased as compared to
the 1996 third quarter,  primarily due to an increase in legal fees and expenses
(which are expected to decline in the future) and severance costs.

         The 1997 quarter  includes an unusual  charge of $.5 million to provide
for costs to vacate an office as part of the Company's further  consolidation of
its operations.  The 1996 quarter  included $.7 million related to the Company's
1996  headquarters  reorganization  and $.3 million to settle the last  disputed
matter from the Company's 1993  restructuring.  (See Note B for a  description.)
After taxes,  unusual charges  contributed  $.01 to the loss in 1997 and $.02 to
the loss in 1996.

         While debt levels were lower in 1997 (the Company paid down $56 million
of debt  with  proceeds  from the sale of its  IMSAMET  subsidiary  in the first
quarter),  interest expense remained comparable primarily because $.9 million of
interest  expense was allocated to  discontinued  operations in the 1996 quarter
and also because the  Company's  average  effective  interest  rate was slightly
higher in 1997.

         Current income tax expense  includes  state and Canadian  income taxes.
The Company recorded deferred federal income tax expense of $2.1 million in 1997
and $1.2 million in 1996  (contributing  $.05 per share to the quarterly loss in
1997 and $.03 per share to the  quarterly  loss in 1996) to reduce  the  benefit
recorded in the first six months of each year, due to lower expected earnings in
each year.

         The  Company  sold its  IMSAMET  subsidiary  in  January  1997.  In the
quarter,  a purchase price adjustment  increased the pre-tax gain by $2 million.
After a deferred income tax charge, the additional gain amounted to $1.3 million
or $.03 per share.  The gain from the sale in 1997 and  IMSAMET's  1996  results
have been classified as discontinued operations.

         Due to the factors  described above, the 1997 net loss was $2.6 million
as compared with the 1996 net loss of $1.8 million.

         There was virtually no Class G preferred stock dividend  requirement in
1996 because almost all of the Class G stock was retired in the first quarter of
that year.

         Industrial Environmental Services revenues for the nine month period of
1997 were  comparable to the same period in 1996.  Most steel industry  customer
sites reported strong production. Alexander Mill Services, Inc., acquired in May
1996,  contributed $7.5 million to revenues in the first nine months as compared
to $4 million in the prior year. However,  revenue increases were largely offset
by a revenue  reduction  resulting  from a strike  (settled in  mid-August) by a
major steel  industry  customer's  employees  and the  mid-1996  loss of a steel
industry  customer that accounted for $4.5 million of revenues in the nine month
period of 1996.  Treatment & Disposal Services revenues increased  significantly
in the nine month period of 1997 as compared to the same period in 1996 due to a
sharp  increase in the volume of electric  arc furnace  dust  stabilized  at the
Company's Ohio and Idaho treatment facilities.

         Industrial  Environmental  Services  gross  profit  decreased  for  the
reasons outlined above and because an ownership  change disrupted  production at
another  customer's  steel mill.  Treatment  & Disposal  Services  gross  profit
increased due to the increase in electric arc furnace dust disposal volume.

         Selling,  general and administrative  expenses increased as compared to
the  same  period  of  1996.  Cost  savings  realized  as a  result  of the 1996
reorganization  (discussed in the next  paragraph)  were partially  offset by an
increase in legal fees and  expenses  (which are expected to decline in future),
severance and other costs.

         The  unusual  charge of $.5 million in 1997 was  provided  for costs to
vacate  an  office  as  part  of  the  Company's  further  consolidation  of its
operations.  Unusual charges in 1996 totaling $5.6 million included $4.4 million
for the Company's 1996  headquarters  reorganization  and $1.2 million to settle
the last disputed matter from the Company's 1993 restructuring.  (See Note B for
a description.)  After taxes,  unusual charges  contributed  $.01 to the loss in
1997 and $.14 to the loss in 1996.

         Even though debt levels were lower in 1997 (the  Company  paid down $56
million of debt with  proceeds  from the sale of its IMSAMET  subsidiary  in the
first quarter),  interest expense  increased $1 million  primarily  because $2.5
million of interest  expense was  allocated to  discontinued  operations  in the
prior year and also because the Company's  average  effective  interest rate was
slightly higher in 1997.

         Current  income tax expense  includes  state and Canadian  income taxes
payable.

         The Company sold its IMSAMET subsidiary in January 1997.  Including the
third quarter purchase price adjustment,  the Company realized an after-tax gain
of $9.6 million or $.24 per share.  The gain from the sale in 1997 and IMSAMET's
1996 results have been classified as discontinued operations.

         Due to the factors described above, including discontinued  operations,
1997  net  income  was  $4.4  million  compared  with  the 1996 net loss of $4.9
million.

         Class G preferred stock dividend  requirements in 1996 were reduced due
to the  retirement  of almost  all of the  outstanding  shares in the 1996 first
quarter, which resulted in a $.3 million retirement gain.

DEFERRED INCOME TAXES
- ---------------------

         The Company has determined that it is more likely than not that it will
earn enough  taxable  income to realize the $14.3 million of deferred tax assets
in its balance  sheet over the next several  years.  Realization  of this amount
will require cumulative taxable earnings of approximately $41 million.  When the
consolidated  results of continuing  operations for the three most recent fiscal
years and current nine month period are adjusted by (1) excluding unusual items,
and (2) adding  back  goodwill  amortization  (which is not  deductible  for tax
purposes), the pre-tax earnings, as adjusted, total over $32 million and average
$8.6 million annually. On this basis, the Company would realize $14.3 million of
deferred tax assets within approximately five years.  On the other hand, because

                                                           
<PAGE>



its net operating loss  carryforwards  expire well into the future,  the Company
would also  realize  $14.3  million of  deferred  tax assets if,  counting  only
profitable years, it earns $41 million of taxable income during the fifteen year
period ending in 2012, so long as the cumulative amount of such earnings reaches
at least $8  million by 2005,  $19  million by 2006,  $28  million by 2008,  $37
million by 2009, and $40 million by 2010.

         In making its  determination  that it is more  likely  than not that it
will earn enough  taxable  income to realize  $14.3  million of net deferred tax
assets,  the  Company  considered  (1) its  cumulative  consolidated  results of
operations  for the three most recent  fiscal years and the first nine months of
1997, (2) the reduction in interest expense obtained by applying the IMSAMET net
proceeds  to reduce  debt,  (3)  ongoing  cost  savings  achieved  with its 1996
reorganization,  and (4) profit  improvements from treating increased volumes of
electric  arc  furnace  dust with its  proprietary  Super  Detox(R)  technology.
Factors which could negatively affect this determination  would include (1) loss
of a major  customer  or  customers,  (2)  prolonged  work  stoppages  at  major
customers,  (3) a major decline in United States steel industry production,  and
(4) a material  decrease in the level of electric  arc  furnace  dust  currently
treated with the Company's proprietary Super Detox(R) technology.


LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

         The Company's  liquidity  requirements arise primarily from the funding
of capital  expenditures,  Treatment & Disposal  Services  trust fund  payments,
working capital needs and debt service  obligations.  Historically,  the Company
has met such  requirements  with cash flows  generated  by  operations  and with
additional debt financing.

         The Company  expects 1997 capital  expenditures  of $30 to $35 million,
primarily for equipment  replacements,  new services,  development of additional
landfill  capacity  and  improvements  to waste  treatment  facilities.  Through
September 30, 1997, the Company spent $21.6 million for capital additions and is
committed for an additional  $12 million,  some of which will not be spent until
1998.

         Treatment & Disposal Services' landfill  permits require the Company to
fund closure and post-closure monitoring and maintenance  obligations  by making
essentially  non-refundable  trust fund payments.  Based on current regulations,
planned improvements to waste treatment facilities and permitted capacity,  such
payments are expected to be approximately  $1.7 million in 1997 and $2.7 million
in 1998,  including  the  reinvestment  of Idaho  trust fund  earnings  that the
Company includes in interest income. Thereafter,  such payments are not expected
to  exceed  the   reinvestment   of  trust  fund  earnings,   based  on  current
requirements.

<PAGE>

         On September 30, 1997,  the Company issued $50 million of 9 3/4% Senior
Notes due 2003,  Series B, having  substantially the same terms as the Company's
existing $220 million of 9 3/4% Senior Notes due 2003.  The Company used most of
the net proceeds to pay off the outstanding balance on its bank credit facility.
The  effective  interest  rate on the new Senior Notes is  approximately  11.1%,
including  amortization of issuance costs. In conjunction with that transaction,
the borrowing capacity under the bank credit facility was reduced by $15 million
and various financial covenants, requiring the Company to meet certain financial
ratios and tests,  were  modified.  As of September  30,  1997,  $6.6 million of
standby letters of credit and no revolving  credit  borrowings were  outstanding
under this $50 million facility.

         During the third quarter, the Company paid $7.9 million of obligations,
including resolution of a disputed matter, related to the 1988 acquisition of IU
International Corporation.

         Cash on hand,  funds from  operations and borrowing  capacity under the
bank credit facility are expected to satisfy the Company's  normal operating and
debt service requirements.

         Because its  businesses  are  environmentally-oriented,  and  therefore
highly regulated,  the Company is subject to violations alleged by environmental
regulators and, occasionally, fines. Such violations and fines have not had, and
are not expected to have, a material  adverse impact on the Company's  business.
It is possible that the future imposition of additional environmental compliance
requirements  could have a material  adverse effect on the Company's  results of
operations or financial condition, but the Company is unable to predict any such
future requirements.

"Second  Supplement")  between  EnviroSource,  Inc., a Delaware corporation (the
"Company"),  and United  States  Trust  Company of New York,  a New York banking
corporation, as trustee (the "Trustee") under the Indenture (defined below).

                             RECITALS OF THE COMPANY
                             -----------------------

         A. The Company and the Trustee have  heretofore  executed and delivered
an Indenture dated as of July 1, 1993 (the "Original Indenture") relating to the
Company's 9 3/4% Senior Notes due 2003.

         B. The Company and the Trustee have heretofore executed and delivered a
First  Supplemental   Indenture  dated  as  of  November  2,  1995  (the  "First
Supplement";  and the Original Indenture as amended by the First Supplement, the
"Indenture") in accordance with the terms of Section 9.02 of the Indenture.

     C. The Company  desires to amend and supplement the Indenture in accordance
with the terms of Section 9.01 thereof and has  requested the Trustee to join in
the execution of this Second Supplement.

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
covenants  set forth in the  Indenture  and herein,  the Company and the Trustee
hereby amend and supplement the Indenture as follows:

                                   AGREEMENTS
                                   ----------

         1. All defined terms used herein and not otherwise defined herein shall
have the meanings ascribed to them in the Indenture.

         2. Clause (i) of Section 4.11(b) of the Indenture is hereby amended by:
(a) deleting such clause in its entirety and (b) inserting, in lieu thereof, the
following new clause (i):

         (i)   Refinancing   Indebtedness;    provided,    however,   that   the
characterization  of Indebtedness as Refinancing  Indebtedness  may not cause or
permit  Indebtedness  Incurred under clauses (ii),  (iii), (v) or (vii) below to
exceed the maximum  amounts  allowed by the terms of each such  clause,  and, to
that  end  (x)  if  Refinancing   Indebtedness  is  Incurred  to  refinance  any
Indebtedness  originally Incurred under either of clauses (ii) or (iii) then the
amount of Indebtedness  permitted under such clause in question shall be reduced
by the amount of such Refinancing Indebtedness (and any Refinancing Indebtedness
that directly or indirectly refinances

<PAGE>
such Refinancing Indebtedness) outstanding at the time of determination, and (y)
if Refinancing Indebtedness is Incurred to refinance any Indebtedness originally
Incurred  under  either of clauses (v) or (vii) then the amount of  Indebtedness
permitted  under such clause in  question  shall be reduced  permanently  by the
amount of such Refinancing Indebtedness;

         3. This Second Supplement shall be governed by the laws of the State of
New York and shall become effective as of the date first above written.

         4.  Except  as  provided  in this  Second  Supplement,  the  terms  and
provisions  of the Indenture  shall  continue to remain in full force and effect
from and after the date hereof.

         5. The Recitals set forth above shall be construed as the  statement of
the Company and, in accordance  with Section 7.04 of the Indenture,  the Trustee
assumes  no  responsibility  as to the  validity  or  adequacy  of  this  Second
Supplement.

         IN WITNESS  WHEREOF,  the  parties  hereto,  by their  duly  authorized
officers,  have executed and delivered this Second  Supplement as of the day and
year first above written.

Indebtedness  for which neither the Company nor any Restricted  Subsidiary shall
continue  to be liable as a result of any such Asset  Sale or repaid,  redeemed,
defeased,  discharged  or  otherwise  retired  in  connection  with or with  the
proceeds  of the assets or  Capital  Stock  which are the  subject of such Asset
Sales  for such  period;  and  provided,  further,  that if the  Company  or any
Restricted Subsidiary shall have made any acquisition of assets or Capital Stock

     PERSON"  HAVE  THE  MEANINGS  GIVEN  TO THEM  BY  REGULATION  S  UNDER  THE
     SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO

                  SECTION 2.03.  EXECUTION AND AUTHENTICATION. An Officer of the

Company  shall sign the Notes for the Company by manual or facsimile  signature.
The Company's seal shall be reproduced on the Notes.

                  If an Officer  whose  signature  is on a Note no longer  holds
that office at the time the Note is authenticated,  the Note shall  nevertheless
be valid.

                  A Note shall not be valid  until  authenticated  by the manual
signature  of the Trustee or the  Authenticating  Agent.  The  signature  of the
Trustee shall be conclusive  evidence that the Note has been authenticated under
this Indenture.  The form of Trustee's certificate of authentication to be borne
by the Notes shall be substantially as set forth in Exhibit A hereto.

                  The Trustee or the Authenticating  Agent shall, upon a written
order of the Company signed by two Officers of the Company,  authenticate  Notes
for original issue up to an aggregate  principal amount stated in paragraph 4 of
the Notes. The aggregate principal amount of Notes outstanding at any time shall
not exceed the amount set forth herein except as provided in Section 2.09.

                  The Trustee may appoint an authenticating  agent acceptable to
the Company to authenticate Notes (the "Authenticating  Agent").  Unless limited
by the terms of such appointment, an Authenticating Agent may authenticate Notes
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 an Agent to deal with the Company or
an Affiliate of the Company.

                  SECTION 2.04.  REGISTRAR  AND PAYING AGENT.  The Company shall
                                 ---------------------------
maintain (i) an office or agency where Notes may be presented  for  registration
of transfer or for exchange  (including any  co-registrar,  the "Registrar") and
(ii) an office or agency  where  Notes may be  presented  for  payment  ("Paying
Agent").  The Registrar shall keep a register of the Notes and of their transfer
and exchange.  The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Paying Agent" includes any additional paying
agent.  The  Company  may change any Paying  Agent,  Registrar  or  co-registrar
without  prior  notice to any Holder of a Note.  The  Company  shall  notify the
Trustee  and the Trustee  shall  notify the Holders of the Notes of the name and
address of any Agent not a party to this  Indenture.  The  Company or any of its
Subsidiaries may act as Paying Agent, Registrar or co-registrar. The Company

<PAGE>

shall enter into an appropriate  agency  agreement with any Agent not a party to
this Indenture, which shall incorporate the provisions of the TIA. The agreement
shall implement the provisions of this Indenture that relate to such Agent.  The
Company  shall notify the Trustee of the name and address of any such Agent.  If
the Company fails to maintain a Registrar or Paying Agent,  or fails to give the
foregoing  notice,  the  Trustee  shall act as such,  and shall be  entitled  to
appropriate compensation in accordance with Section 7.07 hereof.

                  The  Company  initially  appoints  the  Trustee as  Registrar,
Paying Agent and agent for service of notices and demands in connection with the
Notes.

                  SECTION 2.05. LISTS OF HOLDERS OF THE NOTES. The Trustee shall
                                -----------------------------
preserve in as current a form as is reasonably  practicable the most recent list
available  to it of the names and  addresses  of  Holders of the Notes and shall
otherwise comply with TIA ss. 312(a).  If the Trustee is not the Registrar,  the
Company  shall  furnish to the Trustee at least seven  Business Days before each
Interest  Payment  Date and at such other  times as the  Trustee  may request in
writing a list in such form and as of such date as the  Trustee  may  reasonably
require  of the names and  addresses  of Holders  of the  Notes,  including  the
aggregate  principal  amount of the Notes held by each thereof,  and the Company
shall otherwise comply with TIA ss. 312(a).

                  SECTION 2.06. TRANSFER AND EXCHANGE.  When Notes are presented
                                ---------------------
to the Registrar with a request to register the transfer or to exchange them for
an equal principal amount of Notes of other  denominations,  the Registrar shall
register  the  transfer  or make  the  exchange  if its  requirements  for  such
transactions are met; provided,  however, that any Note presented or surrendered
for  registration  of transfer or exchange shall be duly endorsed or accompanied
by a written  instruction of transfer in form  satisfactory to the Registrar and
the  Trustee  duly  executed  by the  Holder  thereof  or by his  attorney  duly
authorized in writing.  To permit  registrations of transfer and exchanges,  the
Company shall issue and the Trustee shall  authenticate Notes at the Registrar's
request, subject to such rules as the Trustee may reasonably require.

                  Neither  the Company  nor the  Registrar  shall be required to
issue,  register the transfer of or exchange (i) any Note for a period beginning
at the opening of business 15 days before any  repurchase of Notes  permitted by
this  Indenture  and ending at the close of business  on the day of  repurchase,
(ii) any Note 15 days before the day of any selection of Notes for redemption in
whole or in part,  except the  unredeemed  portion of any Note being redeemed in
part or (iii) any Note  between a record date and the next  succeeding  Interest
Payment Date.

                  No  service  charge  shall be made to any Holder of a Note for
any  registration  of  transfer  or  exchange  (except  as  otherwise  expressly
permitted  herein),  but the Company may require  payment of a sum sufficient to
cover any  transfer tax or similar  governmental  charge  payable in  connection
therewith (other than such transfer tax or similar  governmental  charge payable
upon exchanges  pursuant to Sections 2.13,  3.06 or 9.05 hereof,  which shall be
paid by the Company).

<PAGE>

                  Prior to due presentment  for  registration of transfer of any
Note,  the  Trustee,  any Agent and the Company may deem and treat the Person in
whose name any Note is  registered  as the  absolute  owner of such Note for the
purpose of receiving  payment of principal of, premium,  if any, and interest on
such Note and for all other  purposes  whatsoever,  whether  or not such Note is
overdue, and neither the Trustee, any Agent nor the Company shall be affected by
notice to the  contrary.  Furthermore,  any Holder of a Global  Note  shall,  by
acceptance of such Global Note, agree that transfers of beneficial  interests in
such Global Note may be effected only through a book-entry  system maintained by
the Holder of such Global Note (or its agent) and that ownership of a beneficial
interest  in the Note shall be required to be  reflected  in a book entry.  When
Notes are  presented  to the  Registrar  or a  co-Registrar  with a  request  to
register the transfer or to exchange them for an equal principal amount of Notes
of other authorized  denominations  (including an exchange of Notes for Exchange
Notes),  the  Registrar  shall  register  the  transfer or make the  exchange as
requested if its  requirements for such  transactions are met;  provided that no
exchanges of Notes for Exchange Notes shall occur until a Registration Statement
shall  have  been  declared  effective  by the SEC  (confirmed  in an  Officers'
Certificate  delivered to the Trustee) and that any Notes that are exchanged for
Exchange Notes shall be cancelled by the Trustee.

                  SECTION 2.07.  BOOK-ENTRY PROVISIONS FOR GLOBAL NOTES. (a) The
                                 --------------------------------------
U.S. Global Notes and Offshore Global Notes initially shall (i) be registered in
the  name of the  Depositary  for  such  Global  Notes  or the  nominee  of such
Depositary,  (ii) be delivered to the Trustee as custodian  for such  Depositary
and (iii) bear legends as set forth in Section 2.02.

                  Members  of,  or  participants  in,  the  Depositary   ("Agent
Members")  shall have no rights under this  Indenture with respect to any Global
Note held on their behalf by the Depositary, or the Trustee as its custodian, or
under the Global Note,  and the  Depositary  may be treated by the Company,  the
Trustee  and any agent of the Company or the  Trustee as the  absolute  owner of
such Global Note 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 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 Note.

                 (b) Transfers of a Global Note shall be limited to transfers of
such Global Note in whole, but not in part, to the Depositary, its successors or
their respective  nominees.  Interests of beneficial owners in a Global Note may
be transferred in accordance with the rules and procedures of the Depositary and
the  provisions of Section 2.08. In addition,  U.S.  Physical Notes and Offshore
Physical Notes shall be  transferred  to all  beneficial  owners in exchange for
their  beneficial  interests in the U.S.  Global  Notes or the  Offshore  Global
Notes,  respectively,  if (i) the  Depositary  notifies  the Company  that it is
unwilling or unable to continue as Depositary  for the U.S.  Global Notes or the
Offshore  Global  Notes,  as the case may be, and a successor  depositary is not
appointed  by the  Company  within  90 days of such  notice  or (ii) an Event of
Default has occurred and  iscontinuing  and the Registrar has received a request
to the foregoing effect from the Depositary.

<PAGE>

                  (c) Any beneficial interest in one of the Global Notes that is
transferred  to a Person who takes  delivery  in the form of an  interest in the
other Global Note will,  upon  transfer,  cease to be an interest in such Global
Note and become an interest  in the other  Global  Note and,  accordingly,  will
thereafter be subject to all transfer restrictions, if any, and other procedures
applicable to  beneficial  interests in such other Global Note for as long as it
remains such an interest.

                  (d) In  connection  with  any  transfer  of a  portion  of the
beneficial interests in a U.S. Global Note or Offshore Global Note to beneficial
owners pursuant to paragraph (b) of this Section, the Registrar shall reflect on
its books and  records the date and a decrease  in the  principal  amount of the
U.S. Global Note or Offshore Global Note, as the case may be, in an amount equal
to the principal  amount of the  beneficial  interest in such Global Notes to be
transferred,  and the Company shall execute,  and the Trustee shall authenticate
and deliver,  one or more U.S. Physical Notes or Offshore Physical Notes, as the
case may be, of like tenor and amount.

                  (e) In connection  with the transfer of an entire U.S.  Global
Note or Offshore  Global Note to beneficial  owners pursuant to paragraph (b) of
this Section, such U.S. Global Note or Offshore Global Note, as the case may be,
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 such U.S.  Global Note or Offshore  Global Note, as the case may be,
an equal aggregate  principal amount of U.S. Physical Notes or Offshore Physical
Notes, as the case may be, of authorized denominations.

                  (f) Any  U.S.  Physical  Note  delivered  in  exchange  for an
interest in a U.S.  Global Note  pursuant to  paragraph  (b), (d) or (e) of this
Section  shall,  except as otherwise  provided by paragraph (e) of Section 2.08,
bear the legend regarding transfer restrictions  applicable to the U.S. Physical
Note set forth in Section 2.02.

                  (g) Any Offshore  Physical  Note  delivered in exchange for an
interest in an Offshore  Global Note  pursuant to  paragraph  (b), (d) or (e) of
this Section  shall,  except as otherwise  provided by paragraph  (e) of Section
2.08, bear the legend regarding transfer restrictions applicable to the Offshore
Physical Note set forth in Section 2.02.

                  (h) The  registered  holder of a Global Note 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 Notes.

In  connection  with the  execution,  authentication  and  delivery of such U.S.
Physical Notes,  the Registrar shall reflect on its books and records a decrease
in the principal  amount of the relevant U.S. Global Note equal to the principal
amount of such U.S. Physical Notes and the Company shall execute and the Trustee
shall  authenticate and deliver one or more U.S.  Physical Notes having an equal
aggregate principal amount.

                  SECTION 2.08. SPECIAL TRANSFER PROVISIONS.  Unless and until a
                                ---------------------------

                  (ii) after such  removal,  the  Registrar  shall  register the

         Physical  Note,  if any, so  transferred  or decrease the amount of the
         U.S. Global Note.

                  (e) Private Placement Legend.  Upon the transfer,  exchange or
                      ------------------------
replacement  of Notes not bearing the Private  Placement  Legend,  the Registrar
shall  deliver  Notes that do not bear the Private  Placement  Legend.  Upon the
transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar  shall deliver only Notes that bear the Private  Placement  Legend
unless either (i) the  circumstances  contemplated  by  paragraphs  (a)(i)(x) or
(c)(ii) of this Section  2.08 exist or (ii) there is delivered to the  Registrar
an Opinion of Counsel reasonably  satisfactory to the Company and the Trustee 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.

                  (f) General. By its acceptance of any Note bearing the Private
                      -------
Placement  Legend,  each Holder of such a Note  acknowledges the restrictions on
transfer of such Note set forth in this  Indenture and in the Private  Placement
Legend and  agrees  that it will  transfer  such Note only as  provided  in this
Indenture.  The Registrar  shall not register a transfer of any Note unless such
transfer  complies with the  restrictions  on transfer of such Note set forth in
this Indenture.  In connection with any transfer of Notes, each Holder agrees by
its  acceptance  of the Notes to  furnish  the  Registrar  or the  Company  such
certifications,  legal  opinions  or other  information  as  either  of them may
reasonably  require to confirm that such  transfer is being made  pursuant to an
exemption from, or a transaction not subject to, the  registration  requirements
of the  Securities  Act;  provided that the  Registrar  shall not be required to
determine (but may conclusively rely on a determination made by the Company with
respect to) the sufficiency of any such certifications,  legal opinions or other
information.

                  The Registrar shall retain copies of all letters,  notices and
other written  communications  received pursuant to Section 2.07 or this Section
2.08 until the earlier of the Maturity  Date or five years after the transfer of
the Notes as set forth  herein.  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 2.09.  REPLACEMENT NOTES.  If any mutilated Note is
                                 -----------------
surrendered to the Trustee, or the Company and the Trustee  receive  evidence to
their satisfaction of the destruction, loss or theft of any Note,  the  Company



<PAGE>

shall issue and the Trustee, upon the written order of the Company signed by two
Officers of the Company,  shall authenticate a replacement Note if the Trustee's
requirements  for  replacements  of Notes are met. If required by the Trustee or
the Company, an indemnity bond must be supplied by the Holder that is sufficient
in the  judgment of the Trustee  and the  Company to protect  the  Company,  the
Trustee,  any Agent or any Authenticating  Agent from any loss which any of them
may suffer if a Note is replaced. Each of the Company and the Trustee may charge
for its expenses in replacing a Note.

                  The Company shall not be required to issue a replacement  Note
for (i) any Note for a period  beginning  at the  opening  of  business  15 days
before the  repurchase  of Notes  permitted by this  Indenture and ending at the
close of  business on the day of such  repurchase,  (ii) any Note 15 days before
the day of any selection of Notes for redemption in whole or in part, except the
unredeemed  portion of any note being redeemed in part or (iii) any Note between
a record date and the next succeeding Interest Payment Date.

                  Every  replacement  Note is an  additional  obligation  of the
Company.

                  SECTION 2.10. PAYING AGENT TO HOLD MONEY IN TRUST. The Company
                                -----------------------------------
shall  require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent shall hold in trust for the benefit of the Holders of the Notes
or the Trustee all money held by the Paying  Agent for the payment of  principal
of, premium,  if any, and interest on the Notes, and shall notify the Trustee of
any Default by the Company in making any such  payment.  While any such  Default
continues, the Trustee may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed.  The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed.  Upon payment over to the Trustee, the Paying Agent (if
other than the Company or a Subsidiary)  shall have no further liability for the
money  delivered to the Trustee.  If the Company or a Subsidiary  acts as Paying
Agent,  it shall  segregate and hold in a separate trust fund for the benefit of
the Holders of the Notes all money held by it as Paying Agent.

          Notwithstanding  any provision herein to the contrary,  an installment
(including,  without limitation,  any redemption or repurchase of Notes pursuant
to this Indenture) of principal or interest on any Note shall be considered paid
on the date due if the  Trustee or Paying  Agent  (other than the Company or any
Subsidiary or Affiliate of the Company)  holds on that date money in immediately
available funds designated for and sufficient to pay the  installment,  provided
that the  Trustee or Paying  Agent is not  legally  prohibited  from  making any
payment of such installment on such Notes.

                  SECTION 2.11.  OUTSTANDING NOTES. The Notes outstanding at any
                                 -----------------
time are all the Notes  authenticated  by the Trustee except for those cancelled
by it,  those  delivered  to it for  cancellation  and those  described  in this
Section as not outstanding.


<PAGE>



                  If a Note is replaced  pursuant  to Section  2.07  hereof,  it
ceases to be outstanding  unless the Trustee  receives proof  satisfactory to it
that the replaced Note is held by a bona fide purchaser.

                  If the principal  amount of any Note is considered  paid under
Section 4.01 hereof,  it ceases to be  outstanding  and interest on it ceases to
accrue.

                  Subject to Section  2.12  hereof,  a Note does not cease to be
outstanding  because the Company, a Subsidiary of the Company or an Affiliate of
the Company holds the Note.

                  SECTION  2.12.  TREASURY  NOTES.  In  determining  whether the
                                  ---------------
Holders  of the  required  principal  amount  of  Notes  have  concurred  in any
direction,  waiver or consent, Notes owned by the Company, any Subsidiary of the
Company  or any  Affiliate  of the  Company  shall be  considered  as though not
outstanding,  except that for purposes of determining  whether the Trustee shall
be protected  in relying on any such  direction,  waiver or consent,  only Notes
which a  Responsible  Officer knows to be so owned shall be so  considered.  The
Company shall notify the Trustee, in writing, when it or any of its Subsidiaries
repurchases or otherwise acquires Notes and of the aggregate principal amount so
repurchased or acquired.  Notwithstanding  the  foregoing,  Notes that are to be
acquired by the Company,  any  Subsidiary  of the Company or an Affiliate of the
Company pursuant to an exchange offer, tender offer or other agreement shall not
be deemed to be owned by the  Company,  such  Subsidiary  of the  Company  or an
Affiliate of the Company  until legal title to such Notes passes to the Company,
such Subsidiary or Affiliate, as the case may be.

                  SECTION 2.13.  TEMPORARY  NOTES.  Until  definitive  Notes are
                                 ----------------
ready for delivery,  the Company may prepare and the Trustee shall  authenticate
temporary  Notes.  Temporary  Notes  shall  be  substantially  in  the  form  of
definitive  Notes  but may have  variations  that the  Company  and the  Trustee
consider  appropriate  for temporary  Notes.  Without  unreasonable  delay,  the
Company shall prepare and the Trustee,  upon receipt of the written order of the
Company  signed by two Officers of the Company,  shall  authenticate  definitive
Notes in exchange for temporary  Notes.  Until such  exchange,  temporary  Notes
shall be entitled to the same rights,  benefits  and  privileges  as  definitive
Notes.

                  SECTION  2.14.  CANCELLATION.  The  Company  at any  time  may
                                  ------------
deliver  Notes to the Trustee for  cancellation.  The Registrar and Paying Agent
shall forward to the Trustee any Notes  surrendered to them for  registration of
transfer,  exchange or payment.  The Trustee shall cancel all Notes  surrendered
for registration of transfer, exchange, payment, replacement or cancellation and
shall destroy  cancelled Notes (subject to the record  retention  requirement of
the  Exchange  Act),  unless the Company  directs them to be returned to it. The
Company may not issue new Notes to replace Notes that it has redeemed or paid or
that have been delivered to the Trustee for  cancellation.  All cancelled  Notes
held by the Trustee shall be destroyed and  certification  of their  destruction
delivered to the Company,  unless by a written order,  signed by two Officers of
the Company, the Company shall direct that cancelled Notes be returned to it.

                  SECTION 2.15. DEFAULTED INTEREST. If the Company defaults in a
                                ------------------
payment of interest on the Notes and if such interest payment is not made within
the grace  period  provided  by  Section  6.01(a),  it shall  pay the  defaulted
interest in any lawful manner plus, to the extent  lawful,  interest  payable on
the  defaulted  interest,  to the  Persons  who are  Holders  of the  Notes on a
subsequent special record date, which date shall be at the earliest  practicable
date but in all events at least five Business Days prior to the payment date, in
each case at the rate  provided  in the Notes and in Section  4.01  hereof.  The
Company  shall,  with the consent of the Trustee,  fix or cause to be fixed each
such special  record date and payment  date. At least 15 days before the special
record date, the Company (or the Trustee if requested in writing by the Company,
in the name of and at the expense of the  Company)  shall mail to Holders of the
Notes a notice that states the special record date, the related payment date and
the amount of such interest to be paid.  Any interest which is paid prior to the
expiration of the grace period  provided in Section 6.01(a) hereof shall be paid
to Holders of the Notes as of the regular  record date for the Interest  Payment
Date for which interest has not been paid.  Notwithstanding  the foregoing,  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
Notes may be listed, and upon such notice as may be required by such exchange.

                                 ------------
may use "CUSIP", "CINS" and "ISIN" numbers and, if it does so, the Trustee shall
use the CUSIP,  CINS and ISIN numbers in notices of  redemption or exchange as a
convenience  to  Holders;  provided  that  any such  notice  may  state  that no
representation  is made as to the correctness or accuracy of the CUSIP, CINS and
ISIN  numbers  printed  in the notice or on the Notes and that  reliance  may be
placed  only on the other  identification  numbers  printed  on the  Notes.  The
Company will  promptly  notify the Trustee of any change in the CUSIP,  CINS and
ISIN numbers.

          SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED. If less than  all  of
                        ---------------------------------
the Notes are to be redeemed,  the Trustee shall select the Notes to be redeemed
among the Holders of the Notes on a pro rata basis, by lot or in accordance with
any other method the Trustee  considers fair and appropriate (and in such manner

partial  redemption,  the  principal  amount  thereof to be redeemed.  Notes and
portions of them  selected  shall be in amounts of $1,000 or whole  multiples of
$1,000;  except  that if all of the Notes of a Holder  are to be  redeemed,  the
entire outstanding  amount of Notes held by such Holder,  even if not a multiple

Trustee shall promptly refund to the Company any remaining excess proceeds.

                  SECTION 3.03. NOTICE OF REDEMPTION.  Subject to the provisions
                                --------------------

         redemption  date upon  surrender  of such Note,  a new Note or Notes in
         principal amount equal to the unredeemed portion shall be issued;

                  (d)      the name and address of the Paying Agent;

                  (f)  that,   unless  the  Company   defaults  in  making  such
         redemption  payment,  interest on Notes called for redemption ceases to
         accrue on and after the redemption date and the only remaining right of
         the Holder is to receive payment of the redemption price upon surrender
         to the Paying Agent of the Notes to be redeemed;

                  (g)  the  paragraph  of  the  Notes  and/or  Section  of  this
         Indenture  pursuant to which the Notes called for  redemption are being
         redeemed; and

                  (h) that no  representation  is made as to the  correctness or
         accuracy of the CUSIP,  CINS and ISIN numbers,  if any,  listed in such
         notice or printed on the Notes.

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee,  at least 35 days but not more than
60 days prior to the redemption date (or such shorter period as may be agreed to
by the Trustee in writing), an Officers' Certificate requesting that the Trustee
give such notice and setting forth the  information  to be stated in such notice
as provided in the preceding paragraph. In any case, failure to give such notice
or any  defect in the  notice to the  Holder of any Note  shall not  affect  the
validity of the proceeding for the redemption of any other Note.

                  SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.  Once notice of
                                 ------------------------------

redemption  become due and  payable  on the  redemption  date at the  redemption
price.

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

Agent money in  immediately  available  funds  sufficient to pay the  redemption
price of and accrued  interest  on all Notes to be  redeemed  on that date.  The

Notes to be redeemed.

                  On and after the  redemption  date,  interest  shall  cease to
accrue on the Notes or the portions of Notes called for redemption. If a Note is
redeemed on or after an interest record date but on or prior to the related

<PAGE>

Interest Payment Date, then any accrued and unpaid interest shall be paid to the
Person in whose name such Note was  registered  at the close of business on such
record  date.  If any Note  called  for  redemption  shall  not be so paid  upon
surrender  for  redemption  because of the failure of the Company to comply with
the preceding  paragraph,  interest shall be paid on the unpaid principal,  from
the  redemption  date until such  principal is paid, and to the extent lawful on
any  interest  not  paid on such  unpaid  principal,  in each  case at the  rate
provided in the Notes and in Section 4.01 hereof.

                  SECTION 3.06. NOTES REDEEMED IN PART. Upon surrender of a Note
                                ----------------------

authenticate  for the Holder of the Notes at the  expense  of the  Company a new
Note  equal  in  principal  amount  to  the  unredeemed   portion  of  the  Note
surrendered.

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

transfer  or  exchange  and where  notices and demands to or upon the Company in
respect of the Notes and this  Indenture  may be served.  The Company shall give
prompt  written  notice to the  Trustee of the  location,  and any change in the

other offices or agencies  where the Notes may be presented or  surrendered  for
any or all such  purposes and may from time to time  rescind such  designations;

relieve  the  Company of its  obligation  to maintain an office or agency in the
Borough of Manhattan,  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 of any change in the location of any such other office or agency.

each of its  Subsidiaries  to pay,  prior to  delinquency,  all material  taxes,
assessments,  and  governmental  levies except as contested in good faith and by
appropriate  proceedings  or where the  failure  to effect  such  payment is not
adverse in any material respect to the Holders of the Notes.

                  SECTION  4.06.  STAY,  EXTENSION  AND USURY LAWS.  The Company
                                  --------------------------------

time insist upon,  plead, or in any manner  whatsoever claim or take the benefit
or advantage of, any stay,  extension or usury law wherever  enacted,  now or at
any time hereafter in force, that may affect the covenants or the performance of
this  Indenture;  and the  Company  (to the extent  that it may  lawfully do so)
hereby  expressly waives all benefit or advantage of any such law, and covenants
that it shall  not,  by  resort  to any such law,  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 has been enacted.

provided,  however,  that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any of its  Subsidiaries  if the Board of  Directors  shall  determine  that the
preservation  thereof is no longer  desirable  in the conduct of the business of
the Company and its Subsidiaries, taken as a whole, and that the loss thereof is
not adverse in any material respect to the Holders of the Notes.

                  SECTION 4.08. MAINTENANCE OF PROPERTIES AND INSURANCE. (a) The
                                ---------------------------------------

maintenance  of any  such  properties  or  disposing  of any of  them,  if  such
discontinuance  or disposal is, in the judgment of an Officer (or other employee

Subsidiary   having   managerial   responsibilities   for  any  such   property,
appropriate.

                  (b) The Company  shall  provide or cause to be  provided,  for

                           (A) 50% of aggregate  Consolidated Net Income accrued
                  during the period (treated as one accounting  period) from the
                  beginning of the fiscal  quarter  beginning  after the date of
                  the  1993  Indenture  to the  end of the  most  recent  fiscal
                  quarter for which financial  statements are available,  (or if
                  such Consolidated Net Income is a deficit,  minus 100% of such
                  deficit),  and minus  100% of the  amount of any  write-downs,
                  write-offs  and  other  negative  revaluations  not  otherwise
                  reflected in Consolidated Net Income during such period;

                           (B) the aggregate  Net Cash Proceeds  received by the
                  Company after the date of the 1993 Indenture from the issue or

                  ownership plan) of Capital Stock (other than Redeemable  Stock
                  or Exchangeable Stock) of the Company and warrants, options or
                  other rights to acquire such Capital Stock;

                           (C) the amount by which the  principal  amount of and
                  any  accrued  interest on  Indebtedness  of the Company or its
                  Restricted   Subsidiaries   is   reduced   on  the   Company's
                  consolidated  balance  sheet upon the  conversion  or exchange
                  (other  than by a  Subsidiary)  subsequent  to the date of the

                  Restricted Subsidiary  convertible or exchangeable for Capital
                  Stock (other than Redeemable  Stock or Exchangeable  Stock) of

                           (D)  an  amount   equal  to  the  net   reduction  in
                  Investments  in  Unrestricted   Subsidiaries   resulting  from
                  payments of interest on Indebtedness, dividends, repayments of
                  loans or advances,  or other transfers of assets, in each case
                  to the Company or any Restricted  Subsidiary from Unrestricted
                  Subsidiaries,   or   from   redesignations   of   Unrestricted
                  Subsidiaries as Restricted  Subsidiaries  (valued in each case
                  as provided in the definition of "Investments"),  or resulting
                  from  the  receipt  of   proceeds   from  the  sale  or  other
                  disposition of an  Unrestricted  Subsidiary,  not to exceed in
                  the  case  of  any  Unrestricted   Subsidiary  the  amount  of
                  Investments  previously  made by the Company or any Restricted
                  Subsidiary  in such  Unrestricted  Subsidiary  and  which  was
                  treated as a  Restricted  Payment  under the  Indenture or the
                  1993 Indenture  (excluding  the amount of any such  Investment
                  made  pursuant to the  provisions  described in clause (iv) of
                  paragraph (c) of Section 4.09 of the 1993 Indenture).

                  (b)  Notwithstanding  the  limitations set forth under clauses
(ii) and (iii) of paragraph (a) above (and in addition to the amount (if any) of
Restricted Payments permitted to be made under such clause (iii)) and as long as
no Default shall have occurred and be  continuing  (or would result  therefrom),
the Company and the Restricted  Subsidiaries may make Restricted  Payments which
in the aggregate  while any of the Notes remain  outstanding  do not exceed $3.0
million.

                  (c) The failure to satisfy the conditions set forth in clauses
(ii) and (iii) of Section 4.09(a) will not prohibit any of the following as long
as the condition set forth in clause (i) of Section 4.09(a) (except as set forth
below) is satisfied (and payments made in accordance with the following will not
(except as set forth in clause  (iii) below) be included in the  calculation  of
Restricted Payments described in clause (iii) of Section 4.09(a) and will not be
taken into account for purposes of paragraph (b) above:

                  (i)  any   purchase  or   redemption   of  Capital   Stock  or
         Subordinated   Obligations   of  the  Company  made  by  exchange  for,
         conversion  of, or in an amount  not in excess of the  proceeds  of the
         substantially  concurrent  sale of, Capital Stock of the Company (other
         than (x) Redeemable Stock or Exchangeable  Stock, and (y) Capital Stock
         issued or sold to a Subsidiary or an employee  stock  ownership  plan);
         provided,  however, that notwithstanding clause (i) of Section 4.09(a),
         the  occurrence or existence of a Default shall not prohibit the making
         of such purchase or  redemption,  and provided,  further,  the Net Cash
         Proceeds from such sale shall be excluded from  subclause (B) of clause
         (iii) of Section 4.09(a);

                  (ii) any purchase or redemption of Subordinated Obligations of
         the Company made by exchange  for, or in an amount not in excess of the
         proceeds of the substantially concurrent Incurrence of, Indebtedness of
         the Company;  provided,  however,  that such  Indebtedness (A) shall be
         contractually  subordinated  in right of  payment  to the Notes and the
         1993 Notes to at least the same extent as the Subordinated  Obligations
         so exchanged, purchased or redeemed, (B) shall be scheduled to mature



<PAGE>


          either (x) no earlier than such Subordinated  Obligations or (y) after
          the Stated  Maturity  of the Notes and (C) shall have an Average  Life
          equal  to or  greater  than  the  Average  Life of  such  Subordinated
          Obligations;

                  (iii)  dividends  paid  within  60  days  after  the  date  of
         declaration  thereof if at such date of declaration such dividend would
         have complied with the provisions of the Indenture;  provided, however,
         that  notwithstanding  clause (i) of Section 4.09(a), the occurrence or
         existence  of a Default at such time of payment  shall not prohibit the
         payment of such  dividends;  and provided,  further that such dividends
         shall be  included  in the  calculation  of the  amount  of  Restricted
         Payments described in clause (iii) of Section 4.09(a);

                  (iv) Investments in Unrestricted  Subsidiaries in an aggregate
         amount not to exceed $5 million in any fiscal year; provided,  however,
         any  portion  thereof not  utilized  under this  Indenture  or the 1993
         Indenture  since the date of the 1993  Indenture may be utilized in any
         subsequent year;

                  (v) any  repurchase of the Company's  Common Stock required to
         be repurchased by the Company's Reorganization Plan as in effect on the
         date of the 1993 Indenture;

                  (vi) loans to  employees  of the  Company or its  Subsidiaries
         extended in connection  with  purchases of Capital Stock of the Company
         not to exceed $3 million in the aggregate at any time outstanding; or

                  (vii) the  redemption  from time to time of all or any part of
         the Company's  Subordinated  Notes due 1998 or the other  retirement of
         such Subordinated Notes called for redemption in 1993.

                                   ---------------------------------------------
RESTRICTIONS AFFECTING SUBSIDIARIES. The Company shall not, and shall not permit
- -----------------------------------
any  Subsidiary  to,  create  or  otherwise  cause or  permit to exist or become
effective  any  consensual  encumbrance  or  restriction  on the  ability of any
Restricted Subsidiary to (i) pay dividends to or make any other distributions on
its Capital Stock to, or pay any Indebtedness or other  obligations owed to, the
Company or any  Restricted  Subsidiary,  (ii) make any loans or  advances to the
Company  or  (iii)  transfer  any of its  property  or  assets  to the  Company;
provided, however, that the foregoing shall not apply to:

                  (a) any encumbrance or restriction pursuant to this Indenture,
         the 1993 Indenture or any other agreement or instrument in effect at or
         entered into on the date of the 1993 Indenture;


<PAGE>



                  (b)  any   encumbrance  or  restriction   with  respect  to  a
         Subsidiary  pursuant  to an  agreement  relating  to  any  Indebtedness
         Incurred  by such  Subsidiary  on or prior  to the  date on which  such
         Subsidiary becomes a Subsidiary and outstanding on such date;

                  (c) any  encumbrance or  restriction  pursuant to an agreement
         effecting (1) a refinancing of  Indebtedness  referred to in clause (a)
         or (b) above or contained in any amendment or modification with respect
         to such Indebtedness or (2) any other Indebtedness Incurred pursuant to
         the provisions described in clause (iii) of Section 4.11(b);  provided,
         however,  that the encumbrances and restrictions  contained in any such
         agreement,  amendment or  modification  are no more  restrictive in any
         material  respect  with  respect to the matters  referred to in clauses
         (i), (ii) and (iii) above than the encumbrances  and restrictions  with
         respect to (x) the Indebtedness  being refinanced,  amended or modified
         in the case of clause (1), or (y) the Credit Agreement,  in the case of
         clause (2);

                  (d)  in  the   case   of   clause   (iii)   above,   customary
         non-assignment  provisions of any leases governing a leasehold interest
         or of any  supply,  license  or  other  agreement  entered  into in the
         ordinary course of business of the Company or any Subsidiary;

                  (e) any  restrictions  with  respect to a  Subsidiary  imposed
         pursuant to an agreement  entered into for the sale or  disposition  of
         all or  substantially  all of the  Capital  Stock  or  assets  of  such
         Subsidiary pending the closing of such sale or disposition;

                  (f) in the case of clause (iii) above.  restrictions contained
         in security  agreements  securing  Indebtedness  of a Subsidiary to the
         extent such restrictions  restrict the transfer of the property subject
         to such security agreements; or

                  (g) any  encumbrance  or  restriction  existing  by  reason of
applicable law.

                  SECTION 4.11.  LIMITATION ON INCURRENCE OF  INDEBTEDNESS.  (a)
                                 -----------------------------------------
The  Company  shall  not,  and shall not permit any  Restricted  Subsidiary  to,
directly or  indirectly,  Incur any  Indebtedness  (other than the Notes and any
other Indebtedness  outstanding as of the date of this Indenture) unless, in the
case of Indebtedness  Incurred by the Company,  after giving effect thereto, the
Consolidated Coverage Ratio determined at the time of such Incurrence is greater
than or equal to 2.25 to 1.

                  (b)  Notwithstanding  the  foregoing,  this Section  shall not
limit the  ability of the  Company  or any  Restricted  Subsidiary  to Incur the
following Indebtedness:

                  (i)  Refinancing  Indebtedness;  provided,  however,  that the
         characterization  of Indebtedness as Refinancing  Indebtedness  may not
         cause or permit Indebtedness Incurred under clauses (ii), (iii), (v) or
         (vii) below to exceed the maximum  amounts allowed by the terms of each
         such clause, and, to that end (x) if Refinancing Indebtedness is


<PAGE>



         Incurred to refinance any Indebtedness originally Incurred under either
         of  clauses  (ii) or (iii) then the  amount of  Indebtedness  permitted
         under such  clause in  question  shall be reduced by the amount of such
         Refinancing   Indebtedness  (and  any  Refinancing   Indebtedness  that
         directly  or  indirectly  refinances  such  Refinancing   Indebtedness)
         outstanding  at the  time  of  determination,  and  (y) if  Refinancing
         Indebtedness  is  Incurred to  refinance  any  Indebtedness  originally
         Incurred  under  either  of  clauses  (v) or (vii)  then the  amount of
         Indebtedness  permitted  under such clause in question shall be reduced
         permanently by the amount of such Refinancing Indebtedness;

                  (ii) in addition to any Indebtedness otherwise permitted to be
         Incurred under the Indenture,  up to $30 million in aggregate principal
         amount  of  such   Indebtedness  of  the  Company  and  its  Restricted
         Subsidiaries at any one time  outstanding;  provided that the amount of
         such Indebtedness Incurred by Restricted  Subsidiaries shall not exceed
         $15 million in aggregate principal amount at any one time outstanding;

                  (iii) in addition to any Indebtedness  otherwise  permitted to
         be  Incurred  under  the  Indenture,   Indebtedness  under  the  Credit
         Agreement  of  up  to  $60  million  in  aggregate   principal   amount
         outstanding at any one time and all Guarantees thereof;

                  (iv)  Indebtedness of the Company which is owed to and held by
         a Wholly Owned Subsidiary and Indebtedness of a Wholly Owned Subsidiary
         which is owed to and held by the Company or a Wholly Owned  Subsidiary;
         provided,  however,  that any  subsequent  issuance  or transfer of any
         Capital Stock which results in any such Wholly Owned Subsidiary ceasing
         to be a Wholly Owned  Subsidiary  or any transfer of such  Indebtedness
         (other  than to the  Company  or a Wholly  Owned  Subsidiary)  shall be
         deemed, in each case, to constitute the Incurrence of such Indebtedness
         by the Company or by a Wholly Owned Subsidiary, as the case may be;

                  (v) Indebtedness solely to finance capital expenditures of the
         Company or any Restricted  Subsidiary in an aggregate  principal amount
         not to exceed in any fiscal year $30 million;  provided,  however, that
         if in any fiscal  year ended after the date of the 1993  Indenture  the
         amount of Indebtedness  Incurred solely to finance capital expenditures
         of the  Company or any  Restricted  Subsidiary  was or is less than $30
         million,  such unused portion may be utilized in any  subsequent  year;
         and provided  further that in  calculating  the amount of  Indebtedness
         Incurred under this clause (v) in any fiscal year,  there shall also be
         included any  Indebtedness  Incurred under clause (vii) of this Section
         4.11(b) in such fiscal year;

                  (vi)   Guarantees  by  the  Company,   or  by  any  Restricted
         Subsidiary,  of  Indebtedness  of  any  Restricted  Subsidiary  or  the
         Company; provided that such Indebtedness is permitted to be Incurred by
         the Company or such Restricted Subsidiary pursuant to the provisions of
         this Section; and

<PAGE>



                  (vii)  Indebtedness  not to exceed $12  million  in  aggregate
         principal  amount  Incurred  since  the date of the 1993  Indenture  as
         industrial development financing by Envirosafe Services of Idaho, Inc.;
         provided that no  Indebtedness  may be Incurred under this clause (vii)
         unless at the time of Incurrence,  and after giving effect thereto, the
         Company  and  its   Restricted   Subsidiaries   could  Incur  $1.00  of
         Indebtedness under clause (v) of this Section 4.11(b).

                  (c) Notwithstanding  Sections 4.11(a) and 4.11(b), the Company
or any Restricted  Subsidiary  shall not Incur any  Indebtedness if the proceeds
thereof are used, directly or indirectly,  to repay,  prepay,  redeem,  defease,
retire, refund or refinance any Subordinated  Obligations unless such repayment,
prepayment,  redemption, defeasance, retirement, refunding or refinancing is not
prohibited by Section 4.09 or unless such Indebtedness  shall be subordinated to
the Notes and the 1993  Notes to at least the same  extent as such  Subordinated
Obligations.

                  SECTION 4.12.  ASSET SALES.  (a)  Neither the  Company nor any
                                 -----------
Restricted Subsidiary shall consummate any Asset Sale unless

                  (i)  the  Company  or  such  Restricted   Subsidiary  receives
         consideration at the time of such Asset Sale at least equal to the fair
         market value, as determined in good faith by the Board of Directors, of
         the shares or assets subject to such Asset Sale (including the value of
         any noncash consideration),

                  (ii) at least 80% of the consideration thereof received by the
         Company or such Restricted Subsidiary is in the form of cash and

                  (iii) an  amount  equal to 100% of the Net  Available  Cash is
         applied by the Company (or such Subsidiary,  as the case may be) as set
         forth herein.

For  purposes of this  Section,  the  following  are deemed to be cash:  (x) any
Indebtedness (as reflected on the Company's  consolidated  balance sheet) of the
Company or any  Restricted  Subsidiary  for which  neither  the  Company nor any
Restricted Subsidiary will continue to be liable,  directly or indirectly,  as a
result of such Asset  Sale,  and (y)  securities  received by the Company or any
Restricted  Subsidiary from such  transferee that are promptly  converted by the
Company or such Restricted  Subsidiary into cash.  Nothing in this Section shall
prohibit the Company or any Subsidiary from transferring  assets,  properties or
Capital  Stock  of any  Subsidiary  to any  Wholly  Owned  Subsidiary  or to the
Company,  nor shall the  provisions  of this Section be  applicable  to any such
transfer.  The Company shall not permit any Unrestricted  Subsidiary to make any
Asset Sale unless such  Unrestricted  Subsidiary  receives  consideration at the
time of such Asset Sale at least equal to the fair market value of the shares or
assets so disposed of as determined in good faith by the Board of Directors.



<PAGE>


                  (b)  Within  365 days  (such  period  being  the  "Application
Period")  following  the  consummation  of an Asset  Sale (or in the case of Net
Available  Cash from the  conversion of  securities,  within such number of days
after the receipt of such cash), the Company or such Restricted Subsidiary shall
apply the Net Available Cash from such Asset Sale as follows:  (i) first, to the
extent  the  Company  or such  Restricted  Subsidiary  elects,  to  reinvest  in
Additional Assets (including by means of an investment in Additional Assets by a
Restricted Subsidiary with Net Available Cash received by the Company or another
Restricted  Subsidiary);  (ii) second,  to the extent of the balance of such Net
Available  Cash after  application  in  accordance  with clause (i),  and to the
extent the Company or such Restricted  Subsidiary  elects,  to prepay,  repay or
purchase Senior  Indebtedness (other than any Preferred Stock) of the Company or
its Restricted  Subsidiaries (in each case other than  Indebtedness  owed to the
Company or an  Affiliate  of the  Company),  (iii)  third,  to the extent of the
balance of such Net Available Cash after  application in accordance with clauses
(i) and (ii), to make an offer to purchase the Notes at a purchase price of 100%
of principal  amount plus accrued  interest to the Purchase  Date (as defined in
Section 4.12(c))  pursuant to and subject to the conditions set forth in Section
4.12(c).  To the extent that any Net Available Cash of Asset Sales remains after
the  application of such Net Available Cash in accordance  with this  paragraph,
the  Company or such  Restricted  Subsidiary  may  utilize  such  remaining  Net
Available Cash in any manner not otherwise prohibited by the Indenture.

                  If  Indebtedness of the Company issued on or after the date of
the 1993  Indenture and ranking pari passu in right of payment with the Notes is
at the time  outstanding,  and the  terms of such  Indebtedness  provide  that a
similar offer is to be made with respect thereto, then the offer to purchase the
Notes shall be made  concurrently  with such other offer, and the Notes and such
other  Indebtedness  shall be accepted pro rata in  proportion  to the aggregate
principal   amounts   which  the   holders  of  Notes  and  such   Indebtedness,
respectively, elect to have redeemed.

                  The Company shall not be required to make an offer to purchase
the  Notes  if the Net  Available  Cash  available  from an  Asset  Sale  (after
application  of the  proceeds  as  provided in clauses (i) and (ii) of the first
paragraph of this Section  4.12(b)) is less than $10 million for any  particular
Asset Sale  (which  lesser  amounts  shall be carried  forward  for  purposes of
determining  whether an offer is required with respect to the Net Available Cash
from any subsequent Asset Sale).

                  Notwithstanding  the  foregoing,  this Section shall not apply
to, or prevent an Asset Sale that also  constitutes a Change of Control provided
the Company has complied with its  obligations  under Section 4.16,  and in such
case no  violation  of this  provision  shall be  deemed to have  occurred  as a
consequence thereof.

                  In the event of the  transfer  of  substantially  all (but not
all) of the  property  and assets of the Company as an entirety to a Person in a
transaction permitted under Article 5, the Successor Corporation shall be deemed
to have sold the properties and assets of the Company not so transferred for



<PAGE>

not so transferred  for purposes of this Section 4.12, and shall comply with the
provisions  of this  Section 4.12 with respect to such deemed sale as if it were
an Asset Sale.

                  (c) In the event of an Asset Sale that requires the Company to
commence an offer to all Holders of the Notes to purchase Notes (the "Asset Sale
Offer")  under clause  (iii) of Section  4.12(b),  the Company  shall follow the
procedures specified below:

                  The Asset  Sale  Offer  shall  remain  open for a period of 20
Business Days  following its  commencement  and no longer,  except to the extent
that a longer  period is required by  applicable  law (the "Offer  Period").  No
later than five  Business  Days after the  termination  of the Offer Period (the
"Purchase  Date"),  the Company  shall  purchase the  principal  amount of Notes
required to be  purchased  pursuant to this Section  4.12(b)  hereof (the "Offer
Amount") or, if less than the Offer Amount has been tendered, all Notes tendered
in response to the Asset Sale Offer.

                  If the  Purchase  Date is on or after an interest  record date
and on or before the related  Interest  Payment Date, any accrued interest shall
be paid to the  Person  in  whose  name a Note is  registered  at the  close  of
business on such record date,  and no  additional  interest  shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

                  Promptly,  and in any  event  prior to the 365th day after the
later of the date of each Asset Sale as to which the Company  must make an Asset
Sale Offer or the receipt of Net  Available  Cash  therefrom,  the Company shall
send, by first class mail, a notice to each of the Holders of the Notes,  with a
copy to the Trustee.  The notice shall  contain all  instructions  and materials
necessary  to enable  such  Holders to tender  Notes  pursuant to the Asset Sale
Offer. The notice,  which shall govern the terms of the Asset Sale Offer,  shall
state:

                  (i) that the Asset Sale Offer is being made  pursuant  to this
         Section  4.12 and the length of time the Asset Sale Offer shall  remain
         open;

                  (ii)     the Offer Amount, the purchase price and the Purchase
         Date;

                  (iii) that any Note not tendered or accepted for payment shall
         continue to accrue interest;

                  (iv) that any Note accepted for payment  pursuant to the Asset
         Sale Offer shall cease to accrue interest after the Purchase Date;

                  (v) that Holders  electing to have a Note  purchased (in whole
         or in part)  pursuant  to any Asset Sale  Offer  shall be  required  to
         surrender the Note,  with the form entitled  "Option of Holder to Elect
         Purchase"  on the  reverse of the Note  completed,  to the  Company,  a
         depositary,  if  appointed  by the  Company,  or a Paying  Agent at the
         address specified in the notice at least three Business Days before the
         Purchase Date;


<PAGE>


                  (vi) that Holders shall be entitled to withdraw their election
         if the  Company,  depositary  or  Paying  Agent,  as the  case  may be,
         receives,  not  later  than  the  expiration  of the  Offer  Period,  a
         telegram,  telex,  facsimile  transmission  or letter setting forth the
         name of the  Holder,  the  principal  amount  of the  Note  the  Holder
         delivered for purchase and a statement  that such Holder is withdrawing
         his election to have the Note purchased;

                  (vii)  that,  if  the  aggregate  principal  amount  of  Notes
         surrendered  by Holders  exceeds the Offer  Amount,  the Company  shall
         select  the  Notes to be  purchased  on a pro  rata  basis  (with  such
         adjustments  as may be deemed  appropriate  by the Company so that only
         Notes in denominations of $1,000, or integral multiples thereof,  shall
         be purchased); and

                  (viii) that Holders  whose Notes were  purchased  only in part
         shall be issued new Notes equal in principal  amount to the unpurchased
         portion of the Notes surrendered.

                  On or before the  Purchase  Date,  the Company  shall,  to the
extent lawful,  accept for payment, on a pro rata basis to the extent necessary,
the Offer  Amount of Notes or portions  thereof  tendered  pursuant to the Asset
Sale Offer,  or if less than the Offer  Amount has been  tendered,  all Notes or
portion thereof  tendered,  and deliver to the Trustee an Officers'  Certificate
stating  that such Notes or portions  thereof  were  accepted for payment by the
Company in  accordance  with the terms of this  Section  4.12(c).  The  Company,
depository or Paying Agent,  as the case may be, shall promptly (but in any case
not later  than five days  after the  Purchase  Date)  mail or  deliver  to each
tendering  Holder an amount equal to the purchase  price of the Note tendered by
such Holder and  accepted by the Company  for  purchase,  and the Company  shall
promptly  issue a new  Note,  and the  Trustee  shall  authenticate  and mail or
deliver  such  new  Note  to  such  Holder  equal  in  principal  amount  to any
unpurchased  portion of the Note surrendered.  Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder  thereof.  The Company
shall  publicly  announce  the  results of the Asset Sale Offer on the  Purchase
Date.

                  Other than as specifically  provided in this Section  4.12(c),
any  redemption  pursuant to this Section  4.12(c) shall be made pursuant to the
provisions of Sections 3.01 through 3.06 hereof.

                  (d) The Company shall 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 the Notes pursuant to
this  Section.  To the extent  that the  provisions  of any  securities  laws or
regulations  conflict  with this  Section,  the  Company  shall  comply with the
applicable  securities  laws and  regulations  and  shall  not be deemed to have
breached its obligations under this Section by virtue thereof.

not, and shall not permit any  of its  Restricted  Subsidiaries  to, directly or
indirectly, enter  into  or  permit  to  exist  any  transaction (including, the

<PAGE>


purchase,  sale,  lease or exchange  of any  property  or the  rendering  of any
service) with any Affiliate of the Company (an "Affiliate Transaction") on terms
that are less  favorable to the Company or such  Restricted  Subsidiary,  as the
case may be, than those which might be obtained at the time of such  transaction
in  arms-length  dealings with a Person who is not such an  Affiliate;  provided
that with respect to any Affiliate  Transaction  involving aggregate payments in
excess of $5 million,  the Company  shall deliver to the Trustee a resolution of
the Board of Directors  set forth in an Officers'  Certificate  certifying  that
such Affiliate  Transaction  complies with the foregoing  requirements  and such
Affiliate  Transaction is approved by a majority of the disinterested members of
the Board of Directors. The foregoing restriction shall not apply to the payment
of any Restricted Payment which is permitted to be paid pursuant to Section 4.09
and transactions  between the Company or any Restricted  Subsidiary,  on the one
hand,  and any other  Subsidiary,  on the other hand, in the ordinary  course of
business.

                  SECTION 4.14.  LIMITATION ON LIENS. The Company shall not, and
                                 -------------------
shall not permit any Restricted Subsidiary to, directly or indirectly,  Incur or
permit  to exist  any Lien of any  nature  whatsoever  on any of its  properties
(including,  without  limitation,  Capital  Stock of a  Restricted  Subsidiary),
whether owned at the date of the Indenture or  thereafter  acquired,  other than
Permitted Liens,  without effectively  providing that the Notes shall be secured
equally and ratably with (or prior to) the obligations so secured for so long as
such obligations are so secured.

                  SECTION  4.15.  LIMITATION  ON  ISSUANCE  OF CAPITAL  STOCK BY
                                  ----------------------------------------------
SUBSIDIARIES. The Company will not permit any Restricted Subsidiary to issue any
- ------------
Capital  Stock to any  Person  (other  than to the  Company  or a  Wholly  Owned
Subsidiary)  or declare or pay  dividends or  distributions  on or repurchase or
redeem any  Capital  Stock of any  Subsidiary  (other  than to the  Company or a
Wholly Owned Subsidiary),  except as otherwise  permitted by Section 4.09 hereof
or the definition of "Restricted Payment".

                  SECTION 4.16. CHANGE OF CONTROL.  (a) Upon the occurrence of a
                                -----------------
Change of Control,  the Company  shall make an offer to purchase all or any part

"Change of Control  Offer") at a purchase  price equal to 101% of the  principal
amount thereof plus accrued and unpaid interest, if any, to the date of purchase
(the "Change of Control Payment") on the terms set forth in this Section. Within
30 days  following  any Change of Control,  the Company shall mail a notice of a
Change of Control  Offer to each Holder and the  Trustee.  The Change of Control
Offer shall  remain open from the time of mailing  until 5 Business  Days before
the date of purchase of the Notes by the Company.  The notice shall  contain all
instructions and materials  necessary to enable such Holders to tender (in whole
or in part) the Notes  pursuant  to the Change of  Control  Offer and shall also
state:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section and that all Notes tendered will be accepted for payment;


<PAGE>


                  (2) the purchase price and the purchase  date,  which shall be
         no  earlier  than 30 days nor  later  than 60 days  from the date  such
         notice is mailed (the "Change of Control Payment Date");

                  (3) that  any  Note  not  tendered  will  continue  to  accrue
         interest;

                  (4) that,  unless the  Company  defaults in the payment of the
         Change of Control  Payment,  all Notes accepted for payment pursuant to
         the Change of Control  Offer shall cease to accrue  interest  after the
         Change of Control Payment Date;

                  (5) that  Holders  electing  to have any Notes  purchased  (in

         required to  surrender  the Notes,  with the form  entitled  "Option of
         Holder to Elect Purchase" on the reverse of the Notes completed, to the
         Paying Agent at the address  specified in the notice (or otherwise make
         effective  delivery of the Notes pursuant to book-entry  procedures and
         the related rules of the applicable depositories) prior to the close of
         business  on the fifth  Business  Day  preceding  the Change of Control
         Payment Date;

                  (6) that Holders will be entitled to withdraw  their  election
         if the Paying Agent  receives,  not later than the close of business on

         purchase,  and a statement that such Holder is withdrawing his election
         to have such Notes purchased; and

                  (7) that Holders whose Notes are being  purchased only in part
         will be issued new Notes equal in principal  amount to the  unpurchased
         portion of the Notes  surrendered,  which  unpurchased  portion must be
         equal to $1,000 in principal amount or an integral multiple thereof.

The Company shall comply,  to the extent  applicable,  with the  requirements of

         transaction on a pro forma basis,  the  Consolidated  Coverage Ratio of
         the Successor  Corporation  is 3.00:1 or more,  the  calculation in the
         preceding  proviso shall be inapplicable and such transaction  shall be
         deemed to have complied with the requirements of such provision.

thereupon or at any time  thereafter be dissolved,  wound up or liquidated.  The
Successor  Corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of the  Company,  all or any of the  Notes  issuable

delivered  to the  Trustee;  and upon the  order  of the  Successor  Corporation
instead of the Company and subject to all the terms,  conditions and limitations

signed and  delivered to the Trustee for that  purpose.  All the Notes so issued
shall in all respects have the same legal rank and benefit under this  Indenture
as the Notes  theretofore or thereafter  issued in accordance  with the terms of
this  Indenture  as though  all such  Notes  had been  issued at the date of the
execution hereof.

such changes in form (but not in substance) may be made in the Notes  thereafter

                           (iii)    consents to the  appointment  of a Custodian

                           (v)      generally is not paying its  debts  as  they
         become due;

                           (vi)     admits in writing its inability to generally
         pay its debts as such debts become due; and

                  (g) a court  of  competent  jurisdiction  enters  an  order or
         decree under any Bankruptcy Law that:

                           (i)      is  for  relief against the Company  or  any
         Significant Subsidiary of the Company in an involuntary case;

                           (ii)  appoints  a  Custodian  of the  Company  or any

consecutive days.

                  The term "Custodian"  means any receiver,  trustee,  assignee,

                  Any notice of  Default  given by the  Trustee  or  Noteholders
under this  Section  must  specify the  Default,  demand that it be remedied and
state that the notice is a "Notice of Default."

<PAGE>



                  Subject  to the  provisions  of  Sections  6.01 and 6.02,  the
Trustee  shall not be charged  with  knowledge  of any Event of  Default  unless
written notice thereof shall have been given to the Trustee by the Company,  the
Paying Agent, any Holder or an agent of any Holder.

                  SECTION 6.02. ACCELERATION. If an Event of Default (other than
                                ------------
an Event of Default  specified in clause (f) or (g) of Section  6.01) occurs and
is continuing,  the Trustee by notice to the Company, or the Holders of not less
than 25% in aggregate  principal amount of the then outstanding Notes by written
notice to the Company and the  Trustee,  may  declare the unpaid  principal  of,
premium,  if any, and any accrued and unpaid interest on all the Notes to be due
and payable immediately.  Upon such declaration the principal,  premium, if any,
and  interest  shall be due and  payable  immediately.  If an  Event of  Default
specified in clause (f) or (g) of Section 6.01 occurs, such an amount 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.  The  Holders  of a majority  in
aggregate  principal amount of the then  outstanding  Notes by written notice to
the Trustee may on behalf of all of the Holders rescind an acceleration  and its
consequences  if the  rescission  would not conflict with any judgment or decree
and if all  existing  Events of  Default  (except  nonpayment  of  principal  or
interest that has become due solely because of the acceleration) have been cured
or waived.

                  SECTION 6.03.  OTHER  REMEDIES.  If an Event of Default occurs
                                 ---------------
and is  continuing,  the Trustee may pursue any available  remedy to collect the
payment of principal,  premium,  if any, and interest on the Notes or to enforce
the performance of any provision of the Notes or this Indenture.

                  The  Trustee  may  maintain a  proceeding  even if it does not
possess any of the Notes or does not produce  any of them in the  proceeding.  A
delay or omission by the Trustee or any Holder of a Note in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default.  All remedies
are cumulative to the extent permitted by law.

                  SECTION 6.04. WAIVER OF PAST DEFAULTS. The Holders of not less
                                -----------------------
than a majority in aggregate  principal amount of the then outstanding  Notes by
written  notice to the  Trustee may on behalf of the Holders of all of the Notes
waive an  existing  Default or Event of Default and its  consequences,  except a
continuing  Default  or Event of Default in the  payment  of the  principal  of,
premium,  if any, or interest on, the Notes. Upon any such waiver,  such Default
shall be cured and 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 impair any right
consequent thereon.

                  SECTION 6.05.  CONTROL BY MAJORITY.  The Holders of a majority
                                 -------------------
in principal  amount of the then outstanding  Notes may direct the time,  method
and place of conducting any  proceeding  for exercising any remedy  available to
the Trustee or  exercising  any trust or power  conferred  on it.  However,  the
Trustee may refuse to follow any direction  that  conflicts with the law or this
Indenture that the Trustee, in its sole discretion, determines may be unduly


<PAGE>

prejudicial  to the  rights of other  Holders of Notes or that may  involve  the
Trustee in personal  liability or the Trustee  determines  that it does not have
adequate indemnification against any loss or expense;  provided that the Trustee
may take any other action deemed proper by the Trustee which is not inconsistent
with such direction.

                  SECTION 6.06.  LIMITATION ON SUITS.  A Holder of  a  Note  may
                                 -------------------
pursue a remedy with respect to this Indenture or the Notes only if:

                  (a)      the Holder of a Note  gives  to  the  Trustee written
         notice of a continuing Event of Default;

                  (b) the  Holders  of at least 25% in  principal  amount of the
         then outstanding  Notes make a written request to the Trustee to pursue
         the remedy;

                  (c) such  Holder of a Note or Holders of Notes  offer and,  if
         requested, provide to the Trustee indemnity satisfactory to the Trustee
         against any loss, liability or expense;

                  (d) the Trustee  does not comply  with the  request  within 60
         days after receipt of the request and the offer and, if requested,  the
         provision of indemnity; and

                  (e) during  such  60-day  period the  Holders of a majority in
         principal amount of the then outstanding  Notes do not give the Trustee
         a direction which, in the opinion of the Trustee,  is inconsistent with
         the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another
Holder of a Note or to obtain a preference or priority over another  Holder of a
Note.

                  SECTION 6.07.  RIGHTS OF HOLDERS OF NOTES TO RECEIVE  PAYMENT.
                                 ----------------------------------------------
Notwithstanding  any other provision of this Indenture,  the right of any Holder
of a Note to receive payment of principal,  premium, if any, and interest on the
Note, on or after the  respective  due dates  expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective  dates,
shall not be impaired or affected without the consent of the Holder of the Note.

                  SECTION  6.08.  COLLECTION  SUIT BY  TRUSTEE.  If an  Event of
                                  ----------------------------
Default  specified  in Section  6.01(a) or (b)  occurs  and is  continuing,  the
Trustee is authorized  to recover  judgment in its own name and as trustee of an
express trust against the Company for the whole amount of principal of, premium,
if any,  and  interest  remaining  unpaid on the Notes and  interest  on overdue
principal and, to the extent  lawful,  interest and 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 and any other  amounts  due the Trustee  pursuant to the
provisions of Section 7.07.


<PAGE>


                  SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee is
                                --------------------------------
authorized  to file such proofs of claim and 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 the Holders of the Notes allowed in any
judicial  proceedings  relative to the Company  (or any other  obligor  upon the
Notes),  its  creditors or its  property and shall be entitled and  empowered to
collect,  receive  and  distribute  any  money  or  other  property  payable  or
deliverable on any such claims and any custodian in any such judicial proceeding
is hereby  authorized  by each  Holder of a Note 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 of the Notes, to pay to the Trustee any amount
due to 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  7.07  hereof.  To the  extent  that  the  payment  of  any  such
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same  shall be  secured  by a Lien on, and shall be paid out of, any and all
distributions,  dividends,  money,  securities  and other  properties  which the
Holders of the Notes may be  entitled to receive in such  proceeding  whether in
liquidation  or under any plan of  reorganization  or  arrangement or otherwise.
Nothing herein  contained  shall be deemed to authorize the Trustee to authorize
or  consent  to or accept or adopt on behalf of any Holder of a Note any plan of
reorganization,  arrangement,  adjustment or composition  affecting the Notes or
the rights of any Holder of a Note thereof,  or to authorize the Trustee to vote
in respect of the claim of any Holder of a Note in any such proceeding.

                  SECTION 6.10.  PRIORITIES.  If the Trustee collects any money
                                 ----------
pursuant to this Article, it shall pay out the money in the following order:

                  First:  to  the  Trustee, its agents and attorneys for amounts
         due under Section 7.07, including  payment of all compensation, expense
         and liabilities incurred, and all advances made, by the Trustee and the
         costs and expenses of collection;

                  Second:  to Holders of Notes for amounts due and unpaid on the
         Notes for principal, premium, if  any,  and  interest, ratably, without
         preference or priority of any kind, according  to  the  amounts due and
         payable on the Notes for  principal,  premium,  if  any,  and interest,
         respectively; and

                  Third: to the Company or to such party as a court of competent
         jurisdiction shall direct.

                  The Trustee  may fix a record  date and  payment  date for any
payment to Holders of Notes.

                  SECTION 6.11.  UNDERTAKING FOR COSTS.  In any suit for the
                                 ---------------------
enforcement of any right or remedy under this Indenture or in any suit against



<PAGE>


the Trustee for any action  taken or omitted by it as a Trustee,  a court in its
discretion  may  require  the  filing  by any party  litigant  in the suit of an
undertaking  to pay the costs of the suit,  and the court in its  discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant  in the suit,  having  due  regard to the  merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07, or a
suit by Holders  of more than 10% in  principal  amount of the then  outstanding
Notes.


                                    ARTICLE 7
                                     TRUSTEE

                  SECTION  7.01.  DUTIES OF TRUSTEE.  (a) If an Event of Default
                                  -----------------
has occurred and is  continuing,  the Trustee shall  exercise such of the rights
and powers vested in it by this  Indenture,  and 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)      Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee  shall be  determined  solely by
         the express  provisions of this  Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others,  and no implied  covenants or obligations shall be read into
         this Indenture against the Trustee, and

                  (ii) in the absence of bad faith on its part,  the Trustee 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 Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine  whether or not they conform to the  requirements
         of this Indenture.

                  (c) The Trustee may not be relieved from  liabilities  for its
own  negligent  action,  its own  negligent  failure to act,  or its own willful
misconduct, except that:

                  (i)      this paragraph does not limit the effect of paragraph
         (b) of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible  Officer,  unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts; and

                  (iii) the  Trustee  shall not be liable  with  respect  to any
         action  it takes or omits to take in good  faith in  accordance  with a
         direction received by it pursuant to Section 6.05 hereof.

to expend or risk its own funds or incur any  liability.  The  Trustee  shall be
under no  obligation  to  exercise  any of its  rights  and  powers  under  this
Indenture at the request of any Holders of Notes,  unless such Holder shall have
offered to the Trustee  security and  indemnity  satisfactory  to it against any
loss, liability or expense.

                  (f) The Trustee  shall not be liable for interest on any money
received  by it except as the  Trustee  may agree in writing  with the  Company.
Money held in trust by the  Trustee  need not be  segregated  from  other  funds
except to the extent required by law.

                  SECTION 7.02.  RIGHTS OF TRUSTEE.  (a)   The  Trustee  may
                                 -----------------
conclusively  rely upon any  document  believed  by it to be genuine and to have
been signed or presented by the proper Person.  The Trustee need not investigate
any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains  from  acting,  it may
require an Officers'  Certificate or an Opinion of Counsel or both,  which shall
conform to Section 10.05 hereof.  The Trustee shall not be liable for any action
it  takes  or  omits  to  take in  good  faith  in  reliance  on such  Officers'
Certificate or Opinion of Counsel.  The Trustee may consult with counsel and the
written  advice of such  counsel or any  Opinion  of  Counsel  shall be full and
complete  authorization  and protection  from liability in respect of any action
taken,  suffered  or  omitted  by it  hereunder  in good  faith and in  reliance
thereon.

                                ----------------------------
individual  or any other  capacity  may become the owner or pledgee of Notes and
may  otherwise  deal with the Company or any  Affiliate  of the Company with the
same rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest it must eliminate such conflict within
90 days,  apply to the  Commission  for  permission  to  continue  as trustee or
resign.  Any Agent may do the same with like rights and  duties.  The Trustee is
also subject to Sections 7.10 and 7.11 hereof.


<PAGE>

                  SECTION 7.04. TRUSTEE'S  DISCLAIMER.  The Trustee shall not be
                                ---------------------
responsible  for and makes no  representation  as to the validity or adequacy of

of the  proceeds  from the Notes or any money  paid to the  Company  or upon the
Company's  direction  under any  provision  of this  Indenture,  it shall not be
responsible for the use or application of any money received by any Paying Agent
other than the Trustee,  and it shall not be  responsible  for any  statement or
recital herein or any statement in the Notes or any other document in connection
with  the  sale of the  Notes  or  pursuant  to this  Indenture  other  than its
certificate of authentication.

                  SECTION  7.05.  NOTICE OF  DEFAULTS.  If a Default or Event of
                                  -------------------
Default occurs and is continuing and if it is known to the Trustee,  the Trustee
shall  mail to  Holders  of Notes a notice of the  Default  or Event of  Default
within 90 days  after it  occurs.  Except  in the case of a Default  or Event of
Default in payment of principal  of,  premium,  if any, or interest on any Note,
the  Trustee  may  withhold  the  notice  if and so long as a  committee  of its
Responsible  Officers in good faith determines that withholding the notice is in
the interests of the Holders of the Notes.

                  SECTION  7.06.  REPORTS  BY  TRUSTEE  TO HOLDERS OF THE NOTES.
                                  ---------------------------------------------
Within 60 days after the  reporting  date stated in Section  10.13,  the Trustee
shall mail to the Holders of the Notes a brief report dated as of such reporting
date that  complies  with TIA ss.  313(a) (but if no event  described in TIA ss.
313(a) has occurred  within the twelve months  preceding the reporting  date, no
report  need be  transmitted).  The  Trustee  also  shall  comply  with  TIA ss.
313(b)(2).  The Trustee  shall also  transmit by mail all reports as required by
TIA ss. 313(c).

                  A copy of  each  report  at the  time  of its  mailing  to the
Holders of Notes  shall be mailed to the Company and filed with the SEC and each
stock  exchange,  if any,  on which the  Notes are  listed.  The  Company  shall
promptly notify the Trustee when the Notes are listed on any stock exchange.

                  SECTION 7.07.  COMPENSATION  AND INDEMNITY.  The Company shall
                                 ---------------------------
pay to the Trustee from time to time reasonable  compensation for its acceptance
of this Indenture and services hereunder.  The Trustee's  compensation shall not
be limited by any law on  compensation  of a trustee  of an express  trust.  The
Company  shall  reimburse the Trustee  promptly upon request for all  reasonable
disbursements,  advances and expenses  incurred or made by it in addition to the
compensation  for its  services.  Such  expenses  shall  include the  reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

                  The  Company  shall  indemnify  the Trustee  for,  and hold it
harmless  against  any  and  all  losses,  liabilities  or  expenses  (including
reasonable  attorneys' fees) incurred by it arising out of or in connection with
the acceptance or administration  of its duties under this Indenture,  except as
set forth below.  The Trustee shall notify the Company promptly of any claim for
which it may seek  indemnity.  Failure by the  Trustee to so notify the  Company
shall not relieve the Company of its obligations  hereunder except to the extent
such failure shall have prejudiced the Company. The Company shall defend the



<PAGE>

claim and the Trustee shall cooperate in the defense.  If the Trustee is advised
by counsel that it may have  available to it defenses which are in conflict with
defenses  available to the Company,  then the Trustee 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.

                  The  obligations  of the Company under this Section 7.07 shall
survive the  satisfaction and discharge of this Indenture and the resignation or
removal of the Trustee.

                  The  Company  need not  reimburse  any  expense  or  indemnify
against  any  loss  or  liability  incurred  by  the  Trustee  through  its  own
negligence, bad faith or willful misconduct.

                  To secure the Company's  payment  obligations in this Section,
the Trustee  shall have a Lien prior to the Notes on all money or property  held
or  collected  by the Trustee,  except that held in trust to pay  principal  and
interest on  particular  Notes.  Such Lien shall  survive the  satisfaction  and
discharge of this Indenture.

                  When the Trustee incurs expenses or renders  services after an
vent of Default specified in Section 6.01 (f) or (g) hereof occurs, the expenses
and the  compensation  for the  services  (including  the  reasonable  fees  and
expenses  of its agents and  counsel)  are  intended to  constitute  expenses of
administration under any Bankruptcy Law.

                  SECTION 7.08. REPLACEMENT OF TRUSTEE. A resignation or removal
                                ----------------------
of the Trustee and  appointment  of a successor  Trustee shall become  effective
only upon the successor Trustee's  acceptance of appointment as provided in this
Section.

                  The  Trustee  may  resign  in  writing  at  any  time  and  be
discharged  from the trust  hereby  created by so  notifying  the  Company.  The
Holders of Notes of a majority in principal amount of the then outstanding Notes
may remove the Trustee by so notifying the Trustee and the Company in writing.
The Company may remove the Trustee if:

                  (a)      the Trustee fails to comply with Section 7.10 hereof;

                  (b) the Trustee is adjudged a bankrupt or an  insolvent  or an
         order for  relief is entered  with  respect  to the  Trustee  under any

                  the  Holders  will  not  recognize  income,  gains or loss for
                  federal  income  tax  purposes  as a result  of the  Company's
                  exercise  of its option  under this  Section  8.03 and will be
                  subject  to federal  income tax on the same  amount and in the
                  same  manner and at the same times as would have been the case

                                    (B) after the passage of 123 days  following
                           the deposit  (except,  with  respect to any funds for
                           the  account of any Holder who may be deemed to be an

                           property  of the  Company,  (I)  assuming  such trust
                           funds remained in the possession of the Trustee prior
                           to  such  court  ruling  to the  extent  not  paid to
                           Holders,  the Trustee  will hold,  for the benefit of
                           the Holders,  a valid and perfected security interest
                           in  such  trust  funds  that  is  not   avoidable  in
                           bankruptcy  or  otherwise  except  for the  effect of

8.07 survive  until the Notes are no longer  outstanding.  Thereafter,  only the
Company's obligations in Sections 7.07, 8.06 and 8.07 shall survive. If and when
a ruling from the Internal  Revenue Service or Opinion of Counsel referred to in
clause (d)(1) above is able to be provided  specifically  without regard to, and
not in reliance upon, the continuance of the Company's obligations under Section
4.01,  then the Company's  obligations  under such Section 4.01 shall cease upon
delivery to the Trustee of such ruling or Opinion of Counsel and compliance with
the other  conditions  precedent  provided for herein relating to the defeasance
contemplated by this Section 8.03.

                  After  any  such  irrevocable  deposit  and  delivery  of  the
documents  referred to above, the Trustee upon written request shall acknowledge
in writing the discharge of the Company's  obligations  under the Notes and this
Indenture  except for those surviving  obligations in the immediately  preceding
paragraph.

         the benefit of the  Holders,  under the terms of an  irrevocable  trust
         agreement in form and  substance  satisfactory  to the Trustee as trust

                  Bankruptcy  Code on interest on the trust funds accruing after
                  the  commencement  of a case under such  statute,  and (y) the
                  Holders  will be entitled to receive  adequate  protection  of

                  used in such case or proceeding; and

                  (e) the Company  has  delivered  to the  Trustee an  Officers'
         Certificate  and an Opinion of Counsel,  in each case  stating that all
         conditions  precedent  provided for herein  relating to the  defeasance
         contemplated by this Section 8.04 have been complied with.

                  SECTION 8.05.  APPLICATION OF TRUST MONEY.  Subject to Section
                                 --------------------------
8.07 of this Indenture, the Trustee or Paying Agent shall hold in trust money or
U.S. Government  Obligations  deposited with it pursuant to Sections 8.01, 8.02,
8.03,  or 8.04 of this  Indenture,  as the  case may be,  and  shall  apply  the
deposited  money and the money from U.S.  Government  Obligations  in accordance
with this  Indenture to the payment of principal  of, and interest on the Notes.
The Trustee shall be under no obligation to invest such money or U.S. Government
Obligations except as it may agree with the Company.

                  SECTION 8.06. REPAYMENT TO COMPANY.  Subject to Sections 7.07,
                                --------------------
8.02,  8.03 and 8.04 of this  Indenture,  the Trustee and the Paying Agent shall
promptly  pay to the Company  upon  request any excess money held by them at any
time and thereupon  shall be relieved  from all  liability  with respect to such
money.  The Trustee and the Paying  Agent shall pay to the Company  upon request
any money held by them for the payment of  principal  or interest  that  remains
unclaimed for two years; provided, however, that the Company shall, if requested
by the  Trustee or the Paying  Agent,  give the  Trustee  or such  Paying  Agent
indemnification  reasonably  satisfactory  to it against  any and all  liability
which may be incurred by it by reason of such  paying,  and  provided,  further,
that the Trustee or such Paying Agent before being  required to make any payment
may cause to be  published  at the expense of the Company once in a newspaper of
general  circulation in the City of New York or mail to each Holder  entitled to
such money at such Holder's address as set forth in the register of Notes notice
that such money remains unclaimed and that after a date specified therein (which
shall be at least 30 days  from the date of such  Publication  or  mailing)  any
unclaimed  balance of such money then  remaining  will be repaid to the Company.
After  payment to the Company,  Holders  entitled to such money must look to the
Company for payment as general  creditors  unless an applicable  law  designates
another  person,  and all  liability  of the Trustee and such Paying  Agent with
respect to such money shall cease.

                  SECTION 8.07. REINSTATEMENT. If the Trustee or Paying Agent is
                                -------------
unable to apply any money or U.S.  Government  Obligations  in  accordance  with
Sections  8.01,  8.02,  8.03 or 8.04 of this  Indenture,  as the case may be, by
reason of any legal  proceeding  or by  reason of any order or  judgment  of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such application, the Company's obligations under this Indenture and the Notes

<PAGE>

shall be revived and  reinstated  as though no deposit had occurred  pursuant to
Sections 8.01,  8.02, 8.03 or 8.04 of this Indenture,  as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money or
U.S. Government Obligations in accordance with Sections 8.01, 8.02, 8.03 or 8.04
of this  Indenture,  as the case may be;  provided that, if the Company has made
any  payment  of  principal  of,  or  interest  on  any  Notes  because  of  the
reinstatement of its obligations,  the Company shall be subrogated to the rights
of the  Holders  of such Notes to receive  such  payment  from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                  SECTION   9.01.   WITHOUT   CONSENT   OF   HOLDERS  OF  NOTES.
                                    -------------------------------------------
Notwithstanding Section 9.02 of this Indenture,  the Company and the Trustee may
amend or  supplement  this  Indenture  or the Notes  without  the consent of any
Holder of a Note:

                  (a)  to cure any ambiguity, omission, defect or inconsistency;

                  (b)  to provide for  uncertificated Notes in addition to or
         in place of certificated Notes;

                  (c) to provide for the assumption of the Company's obligations
         to the  Holders  of the Notes in the case of a merger or  consolidation
         pursuant to Article 5 hereof;

                  (d)  to provide for the acceptance of or the appointment of  a
         successor trustee;

                  (e) to comply with  requirements of the SEC in order to effect
         or maintain the qualification of this Indenture under the TIA; or

                  (f) to make any other change that would provide any additional
         rights  or  benefits  to the  Holders  of the  Notes  or that  does not
         adversely affect the legal rights hereunder of any Holder of the Notes.

                  Upon the request of the Company accompanied by a resolution of
its  Board  of  Directors  authorizing  the  execution  of any such  amended  or
supplemental  Indenture,  and  upon  receipt  by the  Trustee  of the  documents
described in Section 9.06 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 which may be therein  contained,  but the Trustee may but shall not
be obligated to enter into such amended or supplemental  Indenture which affects
its own rights, duties or immunities under this Indenture or otherwise.

<PAGE>

                  SECTION  9.02.  WITH CONSENT OF HOLDERS OF NOTES.  The Company
                                  --------------------------------
and the  Trustee  may amend or  supplement  this  Indenture  or the Notes or any
amended or  supplemental  Indenture  with the written  consent of the Holders of
Notes of not less than a majority  in  aggregate  principal  amount of the Notes
then outstanding  (including consents obtained in connection with a tender offer
or exchange offer for the Notes),  and any existing Default and its consequences
or compliance  with any  provision of this  Indenture or the Notes may be waived
with the consent of the Holders of a majority  in  principal  amount of the then
outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for the Notes).

                  Upon the request of the Company accompanied by a resolution of
its  Board  of  Directors  authorizing  the  execution  of any such  amended  or
supplemental  Indenture,  and  upon the  filing  with the  Trustee  of  evidence
satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid,
and upon  receipt by the  Trustee of the  documents  described  in Section  9.06
hereof, the Trustee shall join with the Company in the execution of such amended
or supplemental  Indenture unless such amended or supplemental Indenture affects
the  Trustee's  own  rights,  duties  or  immunities  under  this  Indenture  or
otherwise,  in which case the Trustee may in its sole discretion,  but shall not
be obligated to, enter into such amended or supplemental Indenture.

                  It shall not be  necessary  for the  consent of the Holders of
Notes under this  Section  9.02 to approve the  particular  form of any proposed
amendment or waiver,  but it shall be  sufficient  if such consent  approves the
substance thereof.

                  After an  amendment,  supplement  or waiver under this Section
becomes  effective,  the  Company  shall mail to the  Holders of Notes  affected
thereby a notice briefly  describing the  amendment,  supplement or waiver.  Any
failure of the Company to mail such notice,  or any defect  therein,  shall not,
however,  in any way  impair or  affect  the  validity  of any such  amended  or
supplemental  Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the
Holders  of  a  majority  in  aggregate  principal  amount  of  the  Notes  then
outstanding  may waive  compliance in a particular  instance by the Company with
any provision of this  Indenture or the Notes.  However,  without the consent of
each Holder affected,  an amendment or waiver may not (with respect to any Notes
held by a non-consenting Holder of Notes):

                  (a) reduce the  principal  amount of Notes whose  Holders must
         consent to an amendment or supplement;

                  (b) reduce the  principal of or change the Stated  Maturity of
         any Note or reduce the premium payable upon the redemption of any Note,
         or change the time at which any Note may or shall be redeemed;

                  (c) reduce  the  rate  of  or  change  the time for payment of
         interest on any Note;

<PAGE>

                  (d) waive a Default  or Event of  Default  in the  payment  of
         principal  of,  premium,  if any, or  interest  on the Notes  (except a
         rescission  of  acceleration  of the Notes by the Holders of at least a
         majority in aggregate  principal amount of the then  outstanding  Notes
         and  a  waiver  of  the  payment   default  that   resulted  from  such
         acceleration);

                  (e) make any Note  payable in money  other than that stated in
         the Notes;

                  (f)  make  any  change  in the  provisions  of this  Indenture
         relating to waivers of past  Defaults or the rights of Holders of Notes
         to receive payments of principal of or interest on the Notes;

                  (g)      waive a redemption payment with respect to any  Note;
         or

                  (h) make any  change in the  foregoing  amendment  and  waiver
         provisions.

                  SECTION  9.03.  COMPLIANCE  WITH TRUST  INDENTURE  ACT.  Every
                                  --------------------------------------
amendment or supplement  to this  Indenture or the Notes shall be set forth in a
amended or supplemental Indenture that complies with the TIA as then in effect.

                  SECTION  9.04.  REVOCATION  AND EFFECT OF  CONSENTS.  Until an
                                  -----------------------------------
amendment,  supplement or waiver becomes effective,  a consent to it by a Holder
of a Note is a continuing  consent by the Holder of a Note and every  subsequent
Holder  of a Note or  portion  of a Note  that  evidences  the same  debt as the
consenting  Holder's  Note,  even if  notation of the consent is not made on any
Note.  However,  any such  Holder of a Note or  subsequent  Holder of a Note may
revoke the  consent as to its Note if the  Trustee  receives  written  notice of
revocation  before  the  date  the  waiver,   supplement  or  amendment  becomes
effective.  An amendment,  supplement or waiver becomes  effective in accordance
with its terms and thereafter binds every Holder of a Note.

                  The  Company  may fix a  record  date  for  determining  which
Holders of the Notes must consent to such  amendment,  supplement or waiver.  If
the Company fixes a record date, the record date shall be fixed at (i) the later
of 30 days prior to the first  solicitation  of such  consent or the date of the
most recent  list of Holders of Notes  furnished  to the  Trustee  prior to such
solicitation  pursuant  to Section  2.05 or (ii) such other date as the  Company
shall designate.

                  SECTION  9.05.  NOTATION ON OR EXCHANGE OF NOTES.  The Trustee
                                  --------------------------------
may place an appropriate  notation  about an amendment,  supplement or waiver on
any Note  thereafter  authenticated.  The Company in exchange  for all Notes may
issue and the Trustee shall  authenticate  new Notes that reflect the amendment,
supplement or waiver.

                  Failure to make the  appropriate  notation or issue a new Note
shall not  affect  the  validity  and effect of such  amendment,  supplement  or
waiver.

                  SECTION  9.06.  TRUSTEE TO SIGN  AMENDMENTS,  ETC. The Trustee
                                  ---------------------------------
shall sign any amended or  supplemental  Indenture  authorized  pursuant to this
Article 9 if the amendment or supplement  does not adversely  affect the rights,
duties,  liabilities  or  immunities  of  the  Trustee.  If  such  amendment  or
supplement  adversely affects the rights,  duties,  liabilities or immunities of
the  Trustee,  the Trustee  may,  but need not,  sign it. The  Trustee  shall be
entitled to receive,  and shall be fully protected in relying upon, an Officers'
Certificate  and an Opinion of Counsel  stating  that any waiver,  amendment  or
supplement  is  authorized  by this  Article  9.  The  Company  may not  sign an
amendment or supplemental Indenture until the Board of Directors approves it.

Indenture  or for any claim  based  on, in  respect  of, or by reason  of,  such
obligations  or their  creation.  Each  Holder of the Notes by  accepting a Note
waives and releases all such  liability.  The waiver and release are part of the
consideration  for  issuance of the Notes.  Such waiver may not be  effective to
waive  liabilities  under the federal  securities laws and it is the view of the
Commission that such a waiver is against public policy.

This is one of the Notes referred to in the within-mentioned Indenture:

UNITED STATES TRUST COMPANY OF NEW YORK, as Trustee

By:__________________________
      Authorized Signatory


<PAGE>
                                 (Back of Note)

                      9 3/4% Senior Note due 2003, Series B


                  Capitalized  terms used herein have the  meanings  assigned to
them in the Indenture (as defined below) unless otherwise indicated.



                  1. Interest.  EnviroSource,  Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at the
rate and in the manner  specified  below.  The Company shall pay interest on the
principal  amount of this Note at the rate per annum of 9 3/4%. The Company will
pay interest  semiannually  on June 15 and December 15 of each year,  commencing
December  15,  1997,  or if  any  such  day is not a  Business  Day on the  next
succeeding  Business Day (each an "Interest Payment Date"). If an exchange offer
registered under the Securities Act is not consummated and a shelf  registration
statement  under the  Securities Act with respect to resales of the Notes is not
declared effective by the Commission,  on or before March 30, 1998 in accordance
with the terms of the  Registration  Rights  Agreement dated as of September 30,
1997  between  the Company and Morgan  Stanley & Co.  Incorporated,  Jefferies &
Company,  Inc. and NationsBanc  Capital Markets,  Inc., the annual interest rate
borne by the Notes shall be increased by 0.5% from the rate shown above accruing
from March 30, 1998, payable in cash semiannually,  in arrears,  on each June 15
and December 15, commencing June 15, 1998, until the exchange offer is completed
or the shelf registration  statement is declared  effective.  The Holder of this
Note is entitled to the benefits of such Registration Rights Agreement.

                  Interest  will be  computed  on the  basis of a  360-day  year
consisting of twelve 30-day  months.  Interest shall accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from June
15,  1997.  To the extent  lawful,  the  Company  shall pay  interest on overdue
principal  at the rate equal to the  interest  rate on the  Notes;  it shall pay
interest on overdue  installments of interest  (without regard to any applicable
grace periods) at the same rate to the extent lawful.

                  2. Method of Payment.  The  Company  will pay  interest on the
Notes (except defaulted  interest) to the Persons who are registered  Holders of
Notes at the close of business on the record date next  preceding  the  Interest
Payment Date,  even if such Notes are cancelled after such record date and on or
before such Interest Payment Date. The Holder hereof must surrender this Note to
a Paying Agent to collect principal payments. The Company will pay principal and
interest  in money of the  United  States  that at the time of  payment is legal
tender for payment of public and private  debts.  The Notes will be payable both
as to principal  and interest at the office or agency of the Company  maintained
for such purpose  within the City and State of New York or, at the option of the
Company, payment of interest may be made by check mailed to the Holders of Notes
at their respective addresses set forth in the register of Holders of Notes.



<PAGE>


Unless  otherwise  designated by the Company,  the Company's office or agency in
New York will be the office of the Trustee maintained for such a purpose.

                  3. Paying Agency and  Registrar.  Initially,  the Trustee will
act as Paying  Agent and  Registrar.  The Company  may change any Paying  Agent,
Registrar or  co-registrar  without  prior  notice to any Holder of a Note.  The
Company may act in any such capacity.

                  4. Indenture. The Company issued the Notes under an Indenture,
dated as of September  30, 1997 (the  "Indenture"),  between the Company and the
Trustee.  The terms of the Notes include those stated in the Indenture and those
made part of the  Indenture by reference to the Trust  Indenture Act of 1939 (15
U.S. Code ss.ss.  77aaa-77bbbb)  as in effect on the date of the Indenture.  The
Notes are  subject to all such terms,  and Holders of Notes are  referred to the
Indenture and such act for a statement of such terms. The terms of the Indenture
shall govern any inconsistencies  between the Indenture and the Notes. The Notes
are unsecured  general  obligations  of the Company  limited to  $50,000,000  in
aggregate principal amount.

                  5. Optional Redemption.  The Company shall not have the option
to redeem the Notes prior to June 15, 1998.  Thereafter,  the Company shall have
the option to redeem the Notes,  in whole or in part,  upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal  amount) set forth below plus accrued and unpaid  interest  thereon to
the  applicable  redemption  date, if redeemed  during the  twelve-month  period
beginning on June 15 of the years indicated below:

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

                  6. Mandatory  Redemption.  The Company will not be required to
make  mandatory  redemption  payments  with  respect to the Notes.  There are no
sinking fund payments with respect to the Notes.

                  7. Repurchase at Option of Holder. (a) If there is a Change of
Control,  the  Company  shall be  required to offer to purchase on the Change of
Control  Payment  Date all  outstanding  Notes at 101% of the  principal  amount

"Option of Holder to Elect Purchase" appearing below.

                  (b) If the Company  consummates any Asset Sales,  and when the
aggregate amount of Net Available Cash from such Asset Sales (after  application
of the  proceeds as provided in clauses (i) and (ii) of the first  paragraph  of
Section  4.12(b) of the  Indenture)  equals or exceeds $10 million,  the Company
shall be required to purchase the maximum  principal amount of Notes that may be
purchased  out of such  Net  Available  Cash at  100%  of the  principal  amount
thereof,  plus accrued and unpaid interest, if any, to the purchase date. If the
aggregate  principal amount of Notes  surrendered by Holders thereof exceeds the
amount of such Net Available Cash, the Notes to be redeemed shall be selected on
a pro rata basis.  Holders of Notes that are the subject of an offer to purchase
will receive an Asset Sale Offer from the Company prior to any related  purchase
date and may elect to have such Notes  purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

                  8. Notice of Redemption.  Notice of redemption shall be mailed
at least 30 days but not more than 60 days  before the  redemption  date to each
Holder whose Notes are to bc redeemed at its  registered  address.  Notes may be
redeemed in part but only in whole multiples of $1,000,  unless all of the Notes
held by a Holder of Notes are to be redeemed.  On and after the redemption date,
interest ceases to accrue on Notes or portions of them called for redemption.

                  9.  Denominations,   Transfer,  Exchange.  The  Notes  are  in
registered  form  without  coupons  in  denominations  of  $1,000  and  integral
multiples of $1,000.  The transfer of Notes may be  registered  and Notes may be
exchanged  as  provided  in the  Indenture.  The  Registrar  and the Trustee may
require  a  Holder  of a  Note,  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 exchange or register
the transfer of any Note or portion of a Note selected for redemption.  Also, it
need not  exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed.

                  10.  Persons Deemed  Owners.  Prior to due  presentment to the
Trustee for  registration  of the transfer of this Note, the Trustee,  any Agent
and the  Company  may deem and  treat  the  Person  in whose  name  this Note is
registered  as its  absolute  owner for the  purpose  of  receiving  payment  of
principal  of,  premium,  if any,  and  interest  on this Note and for all other
purposes  whatsoever,  whether  or not this Note is  overdue,  and  neither  the
Trustee,  any Agent nor the Company shall be affected by notice to the contrary.
The registered Holder of a Note shall be treated as its owner for all purposes.

                  11.  Amendments,  Supplement  and Waivers.  Subject to certain
exceptions,  the Indenture or the Notes may be amended or supplemented  with the
consent of the  Holders of at least a majority in  principal  amount of the then
outstanding Notes, and any existing default or compliance with any provision of

<PAGE>


the  Indenture  or the Notes may be waived  with the consent of the Holders of a
majority in principal amount of the then outstanding Notes.  Without the consent
of any  Holder  of a  Note,  the  Indenture  or the  Notes  may  be  amended  or
supplemented  to cure any  ambiguity,  defect or  inconsistency,  to provide for
uncertificated  Notes  in  addition  to or in place of  certificated  Notes,  to
provide for the assumption of the Company's  obligations to Holders of the Notes
in case of a merger or consolidation,  to make any change that would provide any
additional  rights  or  benefits  of the  Holders  of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder,  or to
comply with the  requirements  of the  Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act.

                  12.   Remedies.   If  any  Event  of  Default  occurs  and  is
continuing,  the Trustee or the Holders of at least 25% in  principal  amount of
the then  outstanding  Notes may  declare  all the  Notes to be due and  payable
immediately.  Notwithstanding the foregoing,  in the case of an Event of Default
arising from certain events of bankruptcy or insolvency,  all outstanding  Notes
will become due and payable  without  further  action or notice.  Holders of the
Notes may not  enforce  the  Indenture  or the Notes  except as  provided in the
Indenture.  Subject to certain  limitations,  Holders of a majority in principal
amount of the then  outstanding  Notes may direct the Trustee in its exercise of
any trust or power. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of Default
relating  to the  payment  of  principal  or  interest)  if it  determines  that
withholding notice is in their interest.  The Holders of a majority in aggregate
principal  amount of the Notes then  outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences  under the Indenture except a continuing Default or
Event of Default in the payment of interest on, or the  principal of, the Notes.
The Company is required to deliver to the Trustee annually a statement regarding
compliance  with the Indenture,  and the Company is required upon becoming aware
of any  Default  or Event of  Default,  to deliver  to the  Trustee a  statement
specifying such Default or Event of Default.

                  13.  Trustee  Dealings  with  Company.  The Trustee  under the
Indenture,  in its individual or any other  capacity,  may make loans to, accept
deposits from, and perform  services for the Company or its Affiliates,  and may
otherwise  deal with the Company or its  Affiliates,  as if it were not Trustee;
however, if the Trustee acquires any conflicting interest it must eliminate such
conflict  within 90 days,  apply to the Commission for permission to continue as
Trustee or resign.

                  14. No Personal Liabilities of Directors,  Officers, Employees
and Stockholders. No director, officer, employee, agent, manager,  incorporator,
stockholder  or other  Affiliate of the Company shall have any liability for any
obligations of the Company under the Notes, the Indenture or for any claim based
on, in  respect  of or by reason of such  obligations  or their  creation.  Each
Holder of a Note by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.


<PAGE>


Such  waiver  may not be  effective  to  waive  liabilities  under  the  federal
securities  laws  and it is the view of the  Commission  that  such a waiver  is
against public policy.

                  15. Authentication.   This  Note  shall  not  be  valid  until
authenticated by the manual signature of the Trustee or an authenticating agent.

                  16. Abbreviations.  Customary abbreviations may be used in the
name of a Holder  of a Note or an  assignee,  such  as:  TEN COM (=  tenants  in
common),  TEN ENT (= tenants by the  entireties),  JT TEN (= joint  tenants with
right of  survivorship  and not as tenants in common),  CUST (= Custodian),  and
U/G/M/A (= Uniform Gifts to Minors Act).

                  17. CUSIP, CINS and ISIN Numbers. Pursuant to a recommendation
promulgated  by the  Committee on Uniform Note  Identification  Procedures,  the
Company has caused  CUSIP,  CINS and ISIN numbers to be printed on the Notes and
has  directed  the  Trustee  to use CUSIP,  CINS and ISIN  numbers in notices of
redemption as a convenience to Holders of Notes. No representation is made as to
the accuracy of such  numbers  either as printed on the Notes or as contained in
any  notice  of  redemption  and  reliance  may be  placed  only  on  the  other
identification numbers placed thereon.

                  The Company  will furnish to any Holder of a Note upon written
request and without charge a copy of the Indenture. Request may be made to:

Offer is made,  and the  Placement  Agents  shall  have the  right,  subject  to
applicable  law, to contact such Holders and otherwise  facilitate the tender of
Registrable Securities in the Exchange Offer.

     (b) In the event that (i) the Company  determines  that the Exchange  Offer
Registration  provided for in Section 2(a) above is not  available or may not be
consummated as soon as practicable after the last Exchange Date because it would
violate  applicable  law or the applicable  interpretations  of the Staff of the
SEC, (ii) the Exchange  Offer is not for any other reason  consummated  by March
30, 1998 or (iii) the Exchange  Offer has been  completed  and in the opinion of
counsel for the Placement  Agents a  Registration  Statement (in addition to the
Exchange Offer  Registration  Statement) must be filed and a non-Exchange  Offer
Prospectus  must be delivered by the  Placement  Agents in  connection  with any
offering  or sale of  Registrable  Securities,  the  Company  shall use its best
efforts to cause to be filed as soon as  practicable  after such  determination,
date or notice of such opinion of counsel is given to the  Company,  as the case
may be, a Shelf Registration  Statement providing for the sale by the Holders of
all of the Registrable  Securities and to have such Shelf Registration Statement
declared  effective  by the SEC.  The Company  agrees to use its best efforts to
keep the Shelf Registration  Statement  continuously  effective until the second
anniversary  of the Closing Date or such shorter period that will terminate when
all of the Registrable  Securities covered by the Shelf  Registration  Statement
have been sold pursuant to the Shelf Registration Statement. The Company further
agrees to  supplement or amend the Shelf  Registration  Statement if required by
the rules,  regulations or instructions applicable to the registration form used
by the Company for such Shelf  Registration  Statement  or by the 1933 Act or by
any  other  rules  and  regulations  thereunder  for  shelf  registration  or if
reasonably  requested by a Holder with respect to  information  relating to such
Holder,  and to use its best  efforts  to cause  any such  amendment  to  become
effective  and such Shelf  Registration  Statement  to become  usable as soon as
thereafter  practicable.  The  Company  agrees  to  furnish  to the  Holders  of
Registrable Securities copies of any such supplement or amendment promptly after
its being used or filed with the SEC.

     (c) The Company shall pay all Registration  Expenses in connection with the
registration pursuant to Section 2(a) or Section 2(b). Each Holder shall pay all
underwriting  discounts and commissions and transfer taxes, if any,  relating to
the sale or disposition of such Holder's Registrable  Securities pursuant to the
Shelf Registration Statement.

     (d) 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 SEC; provided, however, that, if, after it has been declared effective, the
         --------   -------
offering of Registrable Securities pursuant to a Shelf Registration Statement is
interfered  with by any stop order,  injunction or other order or requirement of
the SEC or any other governmental  agency or court, such Registration  Statement
will  be  deemed  not to  have  become  effective  during  the  period  of  such
interference  until the  offering  of  Registrable  Securities  pursuant to such
Registration Statement may legally resume. As provided for in the Indenture,  in
the event that the Exchange Offer is not consummated and a Shelf Registration

<PAGE>


Statement  is not declared  effective on or prior to March 30, 1998,  the annual
interest rate borne by the Securities  will be increased by 0.5% per annum until
the  Exchange  Offer is  consummated  or the  Shelf  Registration  Statement  is
declared effective. Upon consummation of the Exchange Offer or the effectiveness
of the Shelf  Registration  Statement,  the interest rate on the Securities will
decrease to the original interest rate of 9-3/4% per annum.

     (e) Without limiting the remedies available to the Placement Agents and the
Holders, the Company acknowledges that any failure by the Company to comply with
its  obligations  under  Section  2(a) and  Section  2(b)  hereof  may result in
material  irreparable  injury to the  Placement  Agents 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 Placement  Agents or any Holder may obtain such relief as may be required to
specifically  enforce the Company's  obligations  under Section 2(a) and Section
2(b) hereof.

     3. Registration Procedures.
        -----------------------

     In  connection  with the  obligations  of the Company  with  respect to the
Registration  Statements  pursuant to Section 2(a) and Section 2(b) hereof,  the
Company shall as expeditiously as possible:

appropriate  form under the 1933 Act,  which form (x) shall be  selected  by the
Company and (y) shall, in the case of a Shelf Registration, be available for the
sale of the Registrable  Securities by the selling Holders thereof and (z) shall
comply  as to  form  in all  material  respects  with  the  requirements  of the

     (b)  prepare  and  file  with the SEC such  amendments  and  post-effective
amendments  to each  Registration  Statement  as may be  necessary  to keep such
Registration  Statement  effective  for the  applicable  period  and cause  each
Prospectus to be supplemented by any required  prospectus  supplement and, as so
supplemented, to be filed pursuant to Rule 424 under the 1933 Act (to the extent
required  thereunder);  to  keep  each  Prospectus  current  during  the  period
described  under Section 4(3) and Rule 174 under the 1933 Act that is applicable
to transactions  by brokers or dealers with respect to the Registrable  Notes or
Exchange Notes;

     (c) in the  case  of a  Shelf  Registration,  furnish  to  each  Holder  of
Registrable Securities,  to counsel for the Placement Agents, to counsel for the
Holders and to each  Underwriter  of an  Underwritten  Offering  of  Registrable
Securities, if any, without charge, as many copies of each Prospectus, including
each preliminary Prospectus, and any amendment or supplement thereto and such


<PAGE>


other documents as such Holder or Underwriter may reasonably  request,  in order
to  facilitate  the  public  sale  or  other   disposition  of  the  Registrable
Securities;  and the  Company  consents  to the use of such  Prospectus  and any
amendment or supplement thereto in accordance with applicable law by each of the
selling  holders  of  Registrable   Securities  and  any  such  Underwriters  in
connection with the offering and sale of the Registrable  Securities  covered by
and in the manner  described in such  Prospectus  or any amendment or supplement
thereto in accordance with applicable law;

     (d) use its best efforts to register or qualify the Registrable  Securities
under all applicable state  securities or "blue sky" laws of such  jurisdictions
as any Holder of  Registrable  Securities  covered by a  Registration  Statement
shall  reasonably  request in writing  by the time the  applicable  Registration
Statement is declared  effective  by the SEC, to cooperate  with such Holders in
connection  with any  filings  required  to be made with the NASD do any and all
other acts and things in relation to  applicable  state  securities  or blue sky
laws and/or NASD which may be  reasonably  necessary or advisable to enable such
Holder  to  consummate  the  disposition  in  each  such  jurisdiction  of  such
Registrable Securities owned by such Holder; 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 this Section 3(d),  (ii) file any general  consent to service of
process or (iii) subject  itself to taxation in any such  jurisdiction  if it is
not so subject;

     (e) in the case of a Shelf Registration,  notify each Holder of Registrable
Securities, counsel for the Holders and counsel for the Placement Agent promptly
and, if requested by any such Holder or counsel,  confirm such advice in writing
(i)  when  a   Registration   Statement  has  become   effective  and  when  any
post-effective  amendment thereto has been filed and becomes effective,  (ii) of
any request by the SEC or any state  securities  authority  for  amendments  and
supplements  to a  Registration  Statement  and  Prospectus  or  for  additional
information after the Registration Statement has become effective,  (iii) of the
issuance  by  the  SEC or any  state  securities  authority  of any  stop  order
suspending the  effectiveness  of a Registration  Statement or the initiation of
any  proceedings  for that purpose,  (iv) if,  between the  effective  date of a
Registration  Statement  and the closing of any sale of  Registrable  Securities
covered thereby,  the representations and warranties of the Company contained in
any  underwriting  agreement,   securities  sales  agreement  or  other  similar
agreement,  if any, relating to the offering cease to be true and correct in all
material  respects or if the Company receives any  notification  with respect to
the suspension of the  qualification  of the Registrable  Securities for sale in
any  jurisdiction  or the initiation of any proceeding for such purpose,  (v) of
the happening of any event during the period a Shelf  Registration  Statement is
effective which makes any statement made in such  Registration  Statement or the
related  Prospectus  untrue in any material respect or which requires the making
of any changes in such Registration Statement or Prospectus in order to make the

<PAGE>

statements  therein not misleading and (vi) of any  determination by the Company
that  a   post-effective   amendment  to  a  Registration   Statement  would  be
appropriate;

     (f) make  every  reasonable  effort to obtain the  withdrawal  of any order
suspending  the  effectiveness  of a  Registration  Statement  at  the  earliest
possible moment and provide immediate notice to each Holder of the withdrawal of
any such order;

     (g) in the  case  of a  Shelf  Registration,  furnish  to  each  Holder  of
Registrable  Securities who so requests,  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
specifically requested);

     (h) in the case of a Shelf Registration, cooperate with the selling Holders
of Registrable  Securities to facilitate the timely  preparation and delivery of
certificates  representing Registrable Securities to be sold and not bearing any
restrictive  legends  and  enable  such  Registrable  Securities  to be in  such
denominations  (consistent  with the provisions of the Indenture) and registered
in such  names as the  selling  Holders  may  reasonably  request  at least  two
business days prior to the closing of any sale of Registrable Securities;

     (i) in the case of a Shelf  Registration,  upon the occurrence of any event
described in Section  3(e)(v)  hereof,  use its best efforts to prepare and file
with  the  SEC  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  Securities,  such  Prospectus  will not
contain 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 the Holders
to suspend use of the Prospectus as promptly as practicable after the occurrence
of such an event,  and the Holders hereby agree to suspend use of the Prospectus
until the Company has amended or  supplemented  the  Prospectus  to correct such
misstatement or omission;

     (j) a reasonable  time prior to the filing of any  Registration  Statement,
any  Prospectus,  any  amendment  to a  Registration  Statement  or amendment or
supplement  to a  Prospectus  or any  document  which is to be  incorporated  by
reference into a Registration  Statement or a Prospectus after initial filing of
a Registration Statement, provide copies of such document to the Placement Agent
and its counsel (and, in the case of a Shelf Registration Statement, the Holders
and their counsel) and make such of the  representatives of the Company as shall
be reasonably  requested by the Placement Agent or its counsel (and, in the case
of a Shelf Registration  Statement,  the Holders or their counsel) available for
discussion  of such  document,  and  shall  not at any  time  file  or make  any
amendment to the Registration Statement, any Prospectus or any amendment of or

<PAGE>


supplement to a Registration  Statement or a Prospectus or any document which is
to be incorporated  by reference into a Registration  Statement or a Prospectus,
of which  the  Placement  Agent  and its  counsel  (and,  in the case of a Shelf
Registration Statement, the Holders and their counsel) shall not have previously
been advised and furnished a copy or to which the Placement Agent or its counsel
(and,  in the  case of a Shelf  Registration  Statement,  the  Holders  or their
counsel) shall object;

     (k)  obtain a CUSIP  number  for all  Exchange  Securities  or  Registrable
Securities,  as the  case  may  be,  not  later  than  the  effective  date of a
Registration Statement;

     (l) 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  Securities or Registrable  Securities,  as the case may be,  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  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 SEC to enable the  Indenture  to be so
qualified in a timely manner;

     (m) in the case of a Shelf Registration, make available for inspection by a
representative  of the Holders of the  Registrable  Securities,  any Underwriter
participating in any disposition pursuant to such Shelf Registration  Statement,
and attorneys and accountants designated by the Holders, at reasonable times and
in  a  reasonable  manner,  all  financial  and  other  records   (collectively,
"Inspectors"),  pertinent documents and properties of the Company, and cause the
respective  officers,  directors  and  employees  of the  Company  to supply all
information  reasonably  requested by any such  Inspector as shall be reasonably
necessary   to  enable   them  to  exercise   their   relevant   due   diligence
responsibilities  in  connection  with a Shelf  Registration  Statement  (and in
connection  therewith each Inspector shall, as a condition to its  participation
in such investigation and information receipt,  agree in writing not to disclose
any records,  documents,  properties or information that the Company determines,
in good faith, to be confidential and that it notifies the Inspectors in writing
are confidential  unless such disclosure is required for compliance with (i) any
applicable  securities  laws, (ii) a court order or (iii)the  public  disclosure
requirements);

     (n) in the case of a Shelf Registration,  use its best efforts to cause all
Registrable  Securities to be listed on any securities exchange or any automated
quotation  system on which  similar  securities  issued by the  Company are then
listed if  requested  by the Majority  Holders,  to the extent such  Registrable
Securities satisfy applicable listing requirements;


<PAGE>


     (o) use its best efforts to cause the Exchange  Securities  or  Registrable
Securities,  as the  case  may be,  to be  rated  by two  nationally  recognized
statistical  rating  organizations  (as such term is defined  in Rule  436(g)(2)
under the 1933 Act);

     (p) if reasonably requested by any Holder of Registrable Securities covered
by a Shelf  Registration  Statement,  (i) promptly  incorporate  in a Prospectus
supplement or  post-effective  amendment such  information  with respect to such
Holder as such Holder  reasonably  requests to be included therein and (ii) make
all  required  filings  of such  Prospectus  supplement  or such  post-effective
amendment as soon as the Company has received  notification of the matters to be
incorporated in such filing; and

     (q)  in the  case  of a  Shelf  Registration,  enter  into  such  customary
agreements  and take all such other actions in connection  therewith  (including
those  reasonably  requested  by the  Holders of a majority  of the  Registrable
Securities  being sold) in order to expedite or facilitate  the  disposition  of
such  Registrable  Securities  including,  but not limited  to, an  Underwritten
Offering  and in  such  connection,  (i)  to  the  extent  possible,  make  such
representations  and  warranties  to the  Holders and any  Underwriters  of such
Registrable  Securities  with  respect to the  business  of the  Company and its
subsidiaries, the Registration Statement,  Prospectus and documents incorporated
by reference or deemed incorporated by reference, if any, in each case, in form,
substance  and scope as are  customarily  made by  issuers  to  underwriters  in
underwritten  offerings and confirm the same if and when requested,  (ii) obtain
opinions of counsel to the Company (which counsel and opinions,  in form,  scope
and substance,  shall be reasonably  satisfactory to the  representative  of the
Holders,  if any, or  otherwise to the Holders and such  Underwriters  and their
respective  counsel)  addressed  to  each  selling  Holder  and  Underwriter  of
Registrable  Securities,  covering the matters  customarily  covered in opinions
requested in underwritten offerings, (iii)obtain "cold comfort" letters from the
independent certified public accountants of the Company (and, if necessary,  any
other certified  public  accountant of any subsidiary of the Company,  or of any
business  acquired by the Company for which  financial  statements and financial
data are or are required to be included in the Registration Statement) addressed
to each selling Holder and Underwriter of Registrable  Securities,  such letters
to be in customary form and covering matters of the type customarily  covered in
"cold  comfort"  letters in connection  with  underwritten  offerings,  and (iv)
deliver such documents and  certificates  as may be reasonably  requested by the
Holders of a majority in principal  amount of the Registrable  Securities  being
sold or the  Underwriters,  and which are customarily  delivered in underwritten
offerings,  to  evidence  the  continued  validity  of the  representations  and
warranties  of the  Company  made  pursuant  to clause (i) above and to evidence
compliance with any customary conditions contained in an underwriting agreement.

     In the case of a Shelf Registration Statement, the Company may require each
Holder of Registrable Securities to furnish to the Company such information


<PAGE>


regarding  the  Holder  and the  proposed  distribution  by such  Holder of such
Registrable  Securities as the Company may from time to time reasonably  request
in writing.  The Company  shall not be required to include in such  Registration
Statement any Registrable Securities of any Holder pursuant to this Agreement if
such  Holder  fails to furnish to the  Company,  within 20  business  days after
receipt by such Holder of a request  therefor,  such  information as the Company
may reasonably request for use in such Shelf Registration Statement.

     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 of the
kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to a Registration Statement until
such Holder's  receipt of the copies of the  supplemented or amended  Prospectus
contemplated  by Section 3(i) hereof,  and, if so directed by the Company,  such
Holder  will  deliver  to  the  Company  (at  its  expense)  all  copies  in its
possession,  other than permanent file copies then in such Holder's  possession,
of the Prospectus  covering such Registrable  Securities  current at the time of
receipt of such notice. If the Company shall give any such notice to suspend the
disposition of Registrable Securities pursuant to a Registration Statement,  the
Company 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.  The Company may give
any such  notice only twice  during any 365 day period and any such  suspensions
may not  exceed 30 days for each  suspension  and there may not be more than two
suspensions in effect during any 365 day period.

     The  Holders of  Registrable  Securities  covered  by a Shelf  Registration
Statement  who  desire  to do so may  sell  such  Registrable  Securities  in an
Underwritten  Offering. In any such Underwritten Offering, the investment banker
or  investment  bankers and manager or managers (the  "Underwriters")  that will
administer  the  offering  will  be  selected  by the  Majority  Holders  of the
Registrable Securities included in such offering.

     4. Participation of Broker-Dealers in Exchange Offer.
        -------------------------------------------------

     (a) The Staff of the SEC has taken the position that any broker-dealer that
receives  Exchange  Securities  for its own  account  in the  Exchange  Offer in
exchange for Securities that were acquired by such  broker-dealer as a result of
market-making or other trading activities (a "Participating Broker-Dealer"), may
be deemed to be an  "underwriter"  within  the  meaning of the 1933 Act and must
deliver a prospectus meeting the requirements of the 1933 Act in connection with
any resale of such Exchange Securities.

     The  Company  understands  that  it is the  Staff's  position  that  if the
Prospectus  contained in the Exchange Offer  Registration  Statement  includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Securities, without

<PAGE>


naming the  Participating  Broker-Dealers  or specifying  the amount of Exchange
Securities  owned by them,  such  Prospectus  may be delivered by  Participating
Broker-Dealers  to satisfy their prospectus  delivery  obligation under the 1933
Act in connection with resales of Exchange Securities for their own accounts, so
long as the Prospectus otherwise meets the requirements of the 1933 Act.

     (b) In light of the above,  notwithstanding  the other  provisions  of this
Agreement,  the Company  agrees that the  provisions  of this  Agreement as they
relate  to  a  Shelf   Registration  shall  also  apply  to  an  Exchange  Offer
Registration to the extent,  and with such reasonable  modifications  thereto as
may  be,  reasonably  requested  by the  Placement  Agents  or by  one  or  more
Participating Broker-Dealers,  in each case as provided in clause (ii) below, in
order to expedite or facilitate the  disposition  of any Exchange  Securities by
Participating Broker- Dealers consistent with the positions of the Staff recited
in Section 4(a) above; provided that:

     (i) 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(i),  for a period  exceeding 180 days after the last
Exchange  Date (as such  period  may be  extended  pursuant  to the  penultimate
paragraph of Section 3 of this Agreement) and Participating Broker-Dealers shall
not be  authorized  by the  Company  to  deliver  and  shall  not  deliver  such
Prospectus after such period in connection with the resales contemplated by this
Section 4; and

     (ii) the  application  of the Shelf  Registration  procedures  set forth in
Section 3 of this Agreement to an Exchange Offer Registration, to the extent not
required by the  positions of the Staff of the SEC or the 1933 Act and the rules
and regulations thereunder, will be in conformity with the reasonable request to
the Company by the Placement Agent or with the reasonable  request in writing to
the Company by one or more  broker-dealers  who certify to the Placement  Agents
and the Company in writing that they anticipate that they will be  Participating
Broker-Dealers; and provided further that, in connection with such application
                    ---------  -------
of the Shelf Registration procedures set forth in Section 3 to an Exchange Offer
Registration,  the Company  shall be obligated  (x) to deal only with the entity
representing  the  Participating  Broker-Dealers,  which shall be the  Placement
Agents unless they elects not to act as such representative, (y) to pay the fees
and expenses of only one counsel representing the Participating  Broker-Dealers,
which shall be counsel to the Placement Agents unless such counsel elects not to
so act and (z) to cause to be delivered only one, if any, "cold comfort"  letter
and one set of opinions of counsel  with respect to the  Prospectus  in the form
existing on the last Exchange Date and with respect to each subsequent amendment
or supplement, if any, effected during the period specified in clause (i) above.

     (c) The  Placement  Agent  shall have no  liability  to the  Company or any
Holder with  respect to any request  that it may make  pursuant to Section  4(b)
above.

<PAGE>


     5. Indemnification and Contribution.
        --------------------------------

     (a) The Company agrees to indemnify and hold harmless the Placement Agents,
each Holder and each person,  if any, who controls the  Placement  Agents or any
Holder within the meaning of either  Section 15 of the 1933 Act or Section 20 of
the 1934  Act,  or is under  common  control  with,  or is  controlled  by,  the
Placement Agents or any Holder, from and against all losses, claims, damages and
liabilities  (including,   without  limitation,  any  legal  or  other  expenses
reasonably  incurred by the Placement Agents, any Holder or any such controlling
or affiliated  person in connection  with  defending or  investigating  any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
pursuant to which Exchange Securities or Registrable  Securities were registered
under the 1933 Act, including all documents  incorporated  therein by reference,
or caused by any omission or alleged  omission to state  therein a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  or caused by any untrue  statement or alleged untrue statement of a
material fact  contained in any Prospectus  (as amended or  supplemented  if the
Company shall have furnished any amendments or supplements  thereto),  or caused
by any omission or alleged  omission to state therein a material fact  necessary
to make the statements  therein in light of the  circumstances  under which they
were made not  misleading,  except  insofar as such losses,  claims,  damages or
liabilities  are caused by any such  untrue  statement  or  omission  or alleged
untrue  statement or omission based upon  information  relating to the Placement
Agents or any Holder furnished to the Company in writing by the Placement Agents
or any selling  Holder  expressly  for use therein;  provided that the foregoing
indemnity  with  respect to any  preliminary  Prospectus  shall not inure to the
benefit of any Holder from whom the person  asserting  any such losses,  claims,
damages or liabilities  purchased  Securities,  or any person  controlling  such
Holder,  if a copy of the final  Prospectus (as then amended or  supplemented if
the Company shall have furnished any amendments or supplements  thereto) was not
sent or given by or on behalf of such Holder to such person,  if required by law
so to have been delivered,  at or prior to the written  confirmation of the sale
of the Securities to such person,  and if the final Prospectus (as so amended or
supplemented)  would  have  cured the defect  giving  rise to such loss,  claim,
damage or liability.  In connection with any Underwritten  Offering permitted by
Section 3, the Company will also  indemnify the  Underwriters,  if any,  selling
brokers, dealers and similar securities industry professionals  participating in
the distribution, their officers and directors and each Person who controls such
Persons  (within the meaning of the  Securities Act and the Exchange Act) to the
same  extent as  provided  above  with  respect  to the  indemnification  of the
Holders, if requested in connection with any Registration Statement.

     (b) Each Holder  agrees,  severally and not jointly,  to indemnify and hold
harmless the Company,  the Placement Agents and the other selling  Holders,  and
each of their respective directors, officers who sign the Registration Statement
and each Person, if any, who controls the Company,  the Placement Agents and any
other selling  Holder within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act to the same extent as the  foregoing  indemnity  from
the Company to the Placement Agents and the Holders, but only with reference to

<PAGE>


information  relating to such Holder furnished to the Company in writing by such
Holder  expressly  for  use in any  Registration  Statement  (or  any  amendment
thereto) or any Prospectus (or any amendment or supplement thereto).

     (c) In case any proceeding (including any governmental investigation) shall
be instituted  involving any person in respect of which  indemnity may be sought
pursuant  to either  paragraph  (a) or  paragraph  (b) above,  such  person (the
"indemnified  party")  shall  promptly  notify  the  person  against  whom  such
indemnity  may  be  sought  (the  "indemnifying   party")  in  writing  and  the
indemnifying  party, upon request of the indemnified party, shall retain counsel
reasonably  satisfactory to the  indemnified  party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel,  but the fees and expenses of such counsel  shall be at the expense
of such indemnified party unless (i) the indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall not, in connection with any proceeding or related  proceedings in the same
jurisdiction,  be liable for (a) the fees and expenses of more than one separate
firm (in  addition  to any  local  counsel)  for the  Placement  Agents  and all
persons,  if any, who control the Placement  Agents within the meaning of either
Section  15 of the 1933 Act or  Section  20 of the  1934  Act,  (b) the fees and
expenses of more than one separate  firm (in addition to any local  counsel) for
the Company, its directors, its officers who sign the Registration Statement and
each person,  if any, who controls the Company within the meaning of either such
Section  and (c) the fees  and  expenses  of more  than  one  separate  firm (in
addition to any local  counsel)  for all Holders and all  persons,  if any,  who
control any Holders within the meaning of either such Section, and that all such
fees  and  expenses  shall be  reimbursed  as they are  incurred.  In such  case
involving  the Placement  Agents and persons who control the  Placement  Agents,
such firm shall be designated in writing by the Placement  Agents.  In such case
involving the Holders and such persons who control  Holders,  such firm shall be
designated  in writing by the Majority  Holders.  In all other cases,  such firm
shall be designated by the Company.  The indemnifying  party shall not be liable
for any settlement of any proceeding  effected  without its written consent but,
if settled with such consent or if there be a final  judgment for the plaintiff,
the  indemnifying  party  agrees to  indemnify  the  indemnified  party from and
against  any  loss or  liability  by  reason  of such  settlement  or  judgment.
Notwithstanding  the foregoing  sentence,  if at any time an  indemnified  party
shall have requested an indemnifying  party to reimburse the  indemnified  party
for fees and  expenses  of  counsel  as  contemplated  by the  second  and third
sentences  of this  paragraph,  the  indemnifying  party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such  settlement  is entered into more than 30 days after receipt by such
indemnifying  party of the aforesaid  request and (ii) such  indemnifying  party
shall not have  reimbursed the  indemnified  party for such fees and expenses of
counsel in accordance with such request prior to the date of such settlement. No

<PAGE>


indemnifying  party shall,  without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened  proceeding in respect
of which  such  indemnified  party is or could  have been a party and  indemnity
could  have  been  sought  hereunder  by such  indemnified  party,  unless  such
settlement includes an unconditional  release of such indemnified party from all
liability on claims that are the subject matter of such proceeding.

     (d) If the  indemnification  provided for in paragraph (a) or paragraph (b)
of this Section 4 is  unavailable  to an indemnified  party or  insufficient  in
respect of any losses,  claims,  damages or liabilities,  then each indemnifying
party under such  paragraph,  in lieu of  indemnifying  such  indemnified  party
thereunder,  shall  contribute to the amount paid or payable by such indemnified
party as a  result  of such  losses,  claims,  damages  or  liabilities  in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party or parties on the one hand and of the indemnified  party or parties on the
other hand in connection  with the statements or omissions that resulted in such
losses, claims, damages or liabilities,  as well as any other relevant equitable
considerations.  The  relative  fault of the Company  and the  Holders  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 by the Holders
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity  to correct or prevent  such  statement  or  omission.  The Holders'
respective  obligations to contribute  pursuant to this Section 5(d) are several
in proportion to the respective number of Registrable  Securities of such Holder
that were registered pursuant to a Registration Statement.

     (e)  The  Company  and  each  Holder  agree  that it  would  not be just or
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation  or by any other method of  allocation  that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified  party as a result of the losses,  claims,  damages
and  liabilities  referred to in paragraph (d) above shall be deemed to include,
subject  to the  limitations  set  forth  above,  any  legal or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or defending any such action or claim.  Notwithstanding  the  provisions of this
Section 5, no Holder shall be required to indemnify or contribute  any amount in
excess of the amount by which the total  price at which  Registrable  Securities
were sold by such Holder  exceeds the amount of any damages that such Holder has
otherwise  been  required  to pay by reason of such  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 1933 Act) shall be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies  which may  otherwise be available to
any indemnified party at law or in equity.

     The indemnity and contribution provisions contained in this Section 5 shall
remain operative and in full force and effect  regardless of (i) any termination
of this Agreement,  (ii) any investigation made by or on behalf of the Placement
Agents, any Holder or any person controlling the Placement Agents or any Holder,

<PAGE>


or by or on behalf of the  Company,  its  officers  or  directors  or any person
controlling the Company,  (iii) acceptance of any of the Exchange Securities and
(iv)  any  sale of  Registrable  Securities  pursuant  to a  Shelf  Registration
Statement.

     6. Miscellaneous.
        -------------

     (a) No Inconsistent Agreements. The Company has not entered into, and on or
after the date of this  Agreement  will not enter into,  any agreement  which is
inconsistent with the rights granted to the Holders of Registrable Securities in
this Agreement or otherwise  conflicts with the  provisions  hereof.  The rights

unless the Company  has  obtained  the written  consent of Holders of at least a
majority in aggregate principal amount of the outstanding Registrable Securities
affected  by  such  amendment,  modification,  supplement,  waiver  or  consent;
provided,  however,  that no  amendment,  modification,  supplement,  waiver  or
consents  to any  departure  from the  provisions  of Section 5 hereof  shall be
effective as against any Holder of Registrable Securities unless consented to in
writing by such Holder.

advisable to protect its rights or the rights of Holders hereunder.

         (c) Schedule  1.1(b) to the Credit  Agreement is hereby  deleted in its

         SECTION 1.02.  AMENDMENTS TO SECTION 2.  (a)  Section 2.6 of the Credit
         -------------  -----------------------
Agreement  is  hereby  amended  by adding  the  following  paragraph  to the end
thereof:

                  "(e)  Notwithstanding   anything  in  Section  2.6(a)  to  the
         contrary,  as soon as  practical  (but in no event  later  than one (1)
         Business Day) after the issuance of the Series B 1997 Notes, the entire
         amount  of the  Net  After-Tax  Cash  Proceeds  with  respect  to  such
         Prepayment Event shall be paid to the Administrative  Agent and applied
         to prepay the Loans  together  with the  payment in full of all accrued
         interest thereon to and including the date of such prepayment, together
         with any additional  amounts owing  pursuant to Section 2.17.  Upon the
         earlier of (i) receipt by the Administrative Agent of such proceeds or

<PAGE>

         (ii) 5:00 P.M.,  Charlotte,  North  Carolina time on the first Business
         Day  following  the issuance of the Series B 1997 Notes,  the Revolving
         Credit Commitments shall automatically be reduced to $50,000,000."

         (b) Section 2 of the Credit  Agreement is hereby  amended by adding the
following section thereto:

                  "2.18 Increase in  Commitments.  (a) Subject to the conditions
                        ------------------------
         set forth in this  Section  2.18 and  provided  no  Default or Event of
         Default shall have  occurred and be  continuing,  the Revolving  Credit
         Commitments may be increased from time to time, upon the request of the
         Borrower, if an existing Lender agrees to increase its Revolving Credit
         Commitment or any other financial  institution or bank (a "New Lender")
         agrees to provide additional Revolving Credit Commitments.  In no event
         shall  the  aggregate   principal   amount  of  the  Revolving   Credit
         Commitments  exceed  $65,000,000.  Increases  in the  Revolving  Credit
         Commitments  shall  be in  increments  of  $1,000,000  and the  initial
         minimum commitment of any New Lender shall not be less than $5,000,000.

                  (b) If any such additional  Revolving  Credit  Commitments are
         provided by a New Lender,  then such New Lender shall execute a joinder
         or other agreement,  in form and substance  reasonably  satisfactory to
         the Administrative  Agent, wherein the New Lender agrees to be bound by
         all the terms and  conditions  of the  Credit  Agreement,  as  amended,
         applicable to Lenders and the New Lender shall thereafter be a "Lender"
         for all  purposes  of the Credit  Agreement,  as  amended.  Neither the
         Administrative  Agent nor any of the  existing  Lenders  shall have any
         obligation to provide  additional  Revolving  Credit  Commitments or to
         provide  or  identify  any New Lender  willing  to  provide  additional
         Revolving Credit Commitments.

                  (c) Prior to the  effectiveness of the increase in or addition
         to, as the case may be, the Revolving Credit Commitments,  the Borrower
         shall  deliver  to the  Administrative  Agent,  in form  and  substance
         satisfactory to the  Administrative  Agent, in its sole  discretion,  a
         certificate  of a  Responsible  Officer of the Parent  stating that the
         Borrower and the Parent are in pro forma  compliance with all covenants
         contained  in  Section  7.1 of the Credit  Agreement,  before and after
         giving  effect to the  increase in or addition  to, as the case may be,
         the Revolving Credit Commitments."

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