     FIRST  SUPPLEMENTAL  INDENTURE,  dated as of August 4,  1999  (this  "First
Supplemental  Indenture"),  to the  Indenture  dated  as of July 29,  1999  (the
"Original  Indenture")  between SWIFT ENERGY COMPANY,  a Texas  corporation,  as
issuer (the "Company"), and BANK ONE, N.A., as trustee (the "Trustee").

     WHEREAS, the Company and the Trustee have heretofore executed and delivered
the  Original  Indenture  to provide for the  issuance of its  securities  to be
issued in one or more registered series;

     WHEREAS,  Section  9.01 of the  Original  Indenture  provides,  among other
things,  that the  Company  and the  Trustee  may without the consent of Holders
enter into  Indentures  supplemental  to the Original  Indenture to, among other
things,  (a) add to, change or eliminate  any of the  provisions of the Original
Indenture  in  respect  of one or  more  series  of Debt  Securities;  provided,
however,  that any such addition,  change or elimination not otherwise permitted
under  Section  9.01 shall (i)  neither  (A) apply to any Debt  Security  of any
series  created  prior  to the  execution  of such  supplemental  indenture  and
entitled  to the  benefit  of such  provision  nor (B)  modify the rights of the
Holder  of any  such  previously  issued  Debt  Security  with  respect  to such
provision  or (ii)  shall  become  effective  only  when  there is no such  Debt
Security  Outstanding  and (b) establish the form or terms of Debt Securities of
any series as permitted by Sections 2.01 and 2.03.;

     WHEREAS, the Company desires to provide for the issuance of a new series of
Debt  Securities to be designated as the "10.25% Senior  Subordinated  Notes due
2009" (the "10.25%  Notes"),  and to set forth the terms that will be applicable
thereto.

     WHEREAS,  all action on the part of the Company  necessary to authorize the
issuance  of the  10.25%  Notes  under the  Original  Indenture  and this  First
Supplemental  Indenture (the Original Indenture,  as amended and supplemented by
this First Supplemental Indenture, being hereinafter called the "Indenture") has
been duly taken; and

     WHEREAS,  all acts and  things  necessary  to make the 10.25%  Notes,  when
executed  by the  Company  and  authenticated  and  delivered  by the Trustee as
provided in the Original Indenture,  the legal, valid and binding obligations of
the Company,  and to constitute these presents a valid and binding  supplemental
indenture  according  to its terms  binding on the  Company,  have been done and
performed,  and the  execution  of this  First  Supplemental  Indenture  and the
creation  and  issuance  under the  Indenture  of the  10.25%  Notes have in all
respects  been duly  authorized,  and the  Company in the  exercise of the legal
right and power vested in it,  executes  this First  Supplemental  Indenture and
proposes to create, execute, issue and deliver the 10.25% Notes.

     NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH:

     That, in order to establish the designation, form, terms and provisions of,
and to  authorize  the  authentication  and  delivery of the 10.25% Notes and in
consideration  of the acceptance of the 10.25% Notes by the Holders  thereof and
of other good and valuable  consideration,  the receipt and sufficiency of which
are hereby acknowledged, the parties hereto hereby agree as follows:






                                                                               2

     SECTION 1. Creation of 10.25% Notes.  Pursuant to Sections 2.01 and 2.03 of

designated  as the  "10.25%  Senior  Subordinated  Notes due  2009",  limited in
aggregate principal amount to $225,000,000 (which are hereinafter defined as the
"10.25%  Notes" for purposes  this First  Supplemental  Indenture).  The Trustee
shall  authenticate  10.25% Notes for original issue in the aggregate  principal
amount of $125,000,000 (the "Original 10.25% Notes").  The Original 10.25% Notes
shall  be in  the  form  specified  in  Exhibit  A to  this  First  Supplemental
Indenture,  shall have the terms set forth  therein and shall be entitled to the
benefits of the other  provisions of the Original  Indenture as modified by this
First Supplemental Indenture and specified herein.

     With  respect to any 10.25%  Notes  issued after the Issue Date (except for
10.25% Notes authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, other 10.25% Notes pursuant to Section 2.07,  2.08,
2.09, 2.15 or 3.03) (the "Additional 10.25% Notes"),  there shall be established
in or pursuant to a resolution of the Board of Directors of the Company:

          (a) that such  Additional  10.25% Notes shall be issued as part of the
     same series as the Original 10.25% Notes;

          (b) the aggregate  principal  amount of such  Additional  10.25% Notes
     which may be authenticated  and delivered under the Indenture,  which shall
     be in an aggregate principal amount not to exceed $100,000,000  (except for
     Additional  10.25% Notes  authenticated  and delivered upon registration of
     transfer of, or in exchange for, or in lieu of, other 10.25% Notes pursuant
     to Section 2.07, 2.08, 2.09, 2.15 or 3.03 and except for Additional  10.25%
     Notes  which,  pursuant  to Section  2.04,  are  deemed  never to have been
     authenticated and delivered hereunder);

          (c) the issue price and issuance date of such Additional 10.25% Notes,
     including  the date from which  interest on such  Additional  10.25%  Notes
     shall accrue;

          (d) if applicable, that such Additional 10.25% Notes shall be issuable
     in whole or in part in the form of one or more  Global  Securities  and, in
     such case, the respective depositories for such Global Securities, the form
     of any legend or legends that shall be borne by any such Global Security in
     addition  to or in lieu of that set forth in Section  2.15 or Exhibit A and
     any  circumstances  in  addition  to or in lieu of those  set  forth in the
     Indenture in which any such Global Security may be exchanged in whole or in
     part for 10.25% Notes registered,  and any transfer of such Global Security
     in  whole  or in part may be  registered,  in the name or names of  Persons
     other than the  depository for such Global  Security or a nominee  thereof;
     and

          (e) if  applicable,  that such  Additional  10.25% Notes shall not be
     registered  under the  Securities  Act, but shall be issued  pursuant to an
     exemption from  registration  under the  Securities Act bearing  additional
     appropriate legends and shall have the benefit of registration rights.

          Except as set forth above, such Additional 10.25% Notes shall have the
     terms set forth in Exhibit A to this First Supplemental Indenture and shall








                                                                               3

     duplication), as of the date of determination, the remainder of:

          (a) the sum of:

               (1)  discounted  future  net  revenues  from  proved  oil and gas
          reserves of the Company and its Restricted  Subsidiaries calculated in
          accordance  with SEC guidelines  before any state,  federal or foreign
          income  taxes,  as  estimated  by  the  Company  and  confirmed  by  a
          nationally  recognized  firm of independent  petroleum  engineers in a
          reserve  report  prepared as of the end of the Company's most recently
          completed  fiscal  year for which  audited  financial  statements  are
          available,  as  increased  by,  as of the date of  determination,  the
          estimated discounted future net revenues from:






                                                                               4

               (A)  estimated  proved oil and gas reserves  acquired  since such
          year-end,  which reserves were not reflected in such year-end  reserve
          report, and

               (B)  estimated  oil  and  gas  reserves  attributable  to  upward
          revisions  of  estimates  of proved  oil and gas  reserves  since such
          year-end due to exploration,  development or exploitation  activities,
          in each case calculated in accordance  with SEC guidelines  (utilizing
          the prices utilized in such year-end reserve report),

          and  decreased  by,  as of the date of  determination,  the  estimated
          discounted future net revenues from:

               (C) estimated proved oil and gas reserves produced or disposed of
          since such year-end, and

               (D)  estimated  oil and gas  reserves  attributable  to  downward
          revisions  of  estimates  of proved  oil and gas  reserves  since such
          year-end due to changes in geological conditions or other factors that
          would,  in accordance  with  standard  industry  practice,  cause such
          revisions,  in each case  calculated in accordance with SEC guidelines
          (utilizing the prices utilized in such year-end reserve report),

          provided that, in the case of each of the determinations made pursuant
          to clauses (A) through (D), such  increases and decreases  shall be as
          estimated  by the  Company's  petroleum  engineers,  unless there is a
          Material  Change as a result  of such  acquisitions,  dispositions  or
          revisions,  in which event the discounted future net revenues utilized
          for purposes of this clause  (a)(1) shall be confirmed in writing by a
          nationally recognized firm of independent petroleum engineers, and

          (2)  the  capitalized  costs  that  are  attributable  to oil  and gas
     properties  of the  Company  and its  Restricted  Subsidiaries  to which no
     proved oil and gas reserves are attributable,  based on the Company's books
     and records as of a date no earlier than the date of the  Company's  latest
     annual or quarterly financial statements, and

          (3) the Net Working  Capital on a date no earlier than the date of the
     Company's latest annual or quarterly financial statements, and

          (4) the  greater  of the net  book  value  or the  appraised  value as
     estimated by independent  appraisers of other tangible  assets  (including,
     without duplication, Investments in unconsolidated Restricted Subsidiaries)
     of the Company  and its  Restricted  Subsidiaries,  as of a date no earlier
     than the date of the Company's  latest audited  financial  statements.  For
     these purposes,  net book value shall be determined as of a date no earlier
     than the date of our latest annual or quarterly financial  statements,  and
     on a date no  earlier  than  the date of our  latest  annual  or  quarterly
     financial statements;






                                                                               5

     (b) minus the sum of:

          (1) minority interests, and

          (2)  any  net  gas  balancing  liabilities  of  the  Company  and  its
     Restricted Subsidiaries reflected in the Company's latest audited financial
     statements, and

          (3) to the extent included in (a)(1) above, the discounted  future net
     revenues,  calculated  in accordance  with SEC  guidelines  (utilizing  the
     prices utilized in the Company's year-end reserve report),  attributable to
     reserves  that are  required  to be  delivered  to third  parties  to fully
     satisfy the obligations of the Company and its Restricted Subsidiaries with
     respect to Volumetric Production Payments (determined, if applicable, using
     the schedules specified with respect thereto), and

          (4) the discounted future net revenues,  calculated in accordance with
     SEC  guidelines,  attributable to reserves  subject to Dollar-  Denominated
     Production  Payments  that,  based on the estimates of production and price
     assumptions  included in  determining  the  discounted  future net revenues
     specified in (a)(1) above,  would be necessary to fully satisfy the payment
     obligations of the Company and its Restricted  Subsidiaries with respect to
     Dollar-Denominated  Production Payments (determined,  if applicable,  using
     the schedules specified with respect thereto).

          If the  Company  changes its method of  accounting  from the full cost
     method to the successful  efforts method or a similar method of accounting,
     "Adjusted  Consolidated Net Tangible Assets" will continue to be calculated
     as if the Company were still using the full cost method of accounting.

          "Affiliate" of any specified Person means any other Person:

          (a) that  directly or  indirectly  through one or more  intermediaries
     controls,  or is  controlled  by, or is under  common  control  with,  such
     specified Person; or

          (b) that beneficially owns or holds directly or indirectly 10% or more
     of any  class  of the  Voting  Stock  of such  specified  Person  or of any
     Subsidiary of such specified Person.

     For the purposes of this  definition,  "control," when used with respect to

     discount,  the  amount  of such  Indebtedness  shall  at all  times  be the

     responsible  or liable,  directly or indirectly,  as obligor,  Guarantor or
     otherwise; and

          (k) all obligations of the type referred to in clauses (a) through (i)
     of this definition of another Person secured by any Lien on any Property of
     such Person (whether or not such obligation is assumed by such Person), the
     amount of such  obligation  being  deemed to be the  lesser of the value of
     such Property or the amount of the obligation so secured;

provided,  however,  that Indebtedness shall not include Production Payments and
Reserve Sales.  For purposes of this  definition,  the maximum fixed  repurchase
price of any  Disqualified  Stock  that does not have a fixed  repurchase  price
shall be calculated in accordance with the terms of such  Disqualified  Stock as
if such  Disqualified  Stock were repurchased on any date on which  Indebtedness
shall be required to be determined pursuant to the Indenture; provided, however,
that if such  Disqualified  Stock is not then permitted to be  repurchased,  the
repurchase price shall be the book value of such Disqualified  Stock. The amount
of Indebtedness  of any Person at any date shall be the  outstanding  balance at
such date of all  unconditional  obligations as described  above and the maximum
liability at such date in respect of any contingent obligations described above.

     Property (including any conditional sale or other title retention agreement

     secured by a Lien on the property being leased.

               The  limitations  set forth in the preceding  paragraph  will not
          prevent  the  Company or any  Restricted  Subsidiary  from  making the
          following  Restricted  Payments  so long as, at the time  thereof,  no
          Default or Event of Default shall have occurred and be continuing:

          (a) the payment of any dividend on Capital Stock of the Company or any
     Restricted  Subsidiary within 60 days after the declaration  thereof, if at

     the exercise of stock  options or similar  rights if such shares  represent

     with satisfying Federal income tax obligations; provided, however, that the
     aggregate  amount  of  such  repurchase,   redemptions,   acquisitions  and
     retirements shall not exceed the sum of:

               (1) $2.0 million in any twelve-month period, and

               (2) the aggregate net proceeds,  if any,  received by the Company
          during  such  twelve-month  period from any  issuance of such  Capital

          (c) the purchase,  redemption or other  acquisition  or retirement for
     value of any Capital Stock of the Company or any Restricted Subsidiary,  in

          made pursuant to item (1) of this clause (f).

The actions described in clauses (a) and (b) of this paragraph shall be included
in the calculation of the amount of Restricted  Payments.  The actions described
in clauses  (c),  (d),  (e) and (f) of this  paragraph  shall be excluded in the
calculation  of the amount of  Restricted  Payments,  provided that the net cash
proceeds from any issuance or sale of Capital  Stock of the Company  pursuant to
such clause (c), (d) or (e) shall be excluded from any calculations  pursuant to
clause (2), (3) or (4) under the immediately preceding paragraph.

          SECTION  4.13.  Limitation  on  Issuance  or Sale of Capital  Stock of
     Restricted Subsidiaries. The Company will not:

          (a) permit any  Restricted  Subsidiary to sell or otherwise  issue any
     Capital  Stock  other  than  to the  Company  or one  of its  Wholly  Owned
     Subsidiaries; or

          (b) sell,  pledge,  hypothecate or otherwise  dispose of any shares of
     Capital  Stock of any  Restricted  Subsidiary,  or  permit  any  Restricted
     Subsidiary to do so,

         except, in each case, for:

               (1) directors' qualifying shares,

               (2) the  Capital  Stock  of a  Restricted  Subsidiary  owned by a
          Person  at the time such  Restricted  Subsidiary  became a  Restricted
          Subsidiary or acquired by such Person in connection with the formation
          of such Restricted Subsidiary, or transfers thereof, or

               (3) a sale of all the Capital  Stock of a  Restricted  Subsidiary
          owned by the Company or its  Subsidiaries  effected in accordance with
          Section 4.14.

     In the event of the  consummation  of a sale of all the Capital  Stock of a
Restricted Subsidiary pursuant to the foregoing clause (3) and the execution and
delivery of a supplemental  indenture in form  satisfactory to the Trustee,  any







                                                                              38

such Restricted Subsidiary that is also a Subsidiary Guarantor shall be released
from all its obligations under its Subsidiary Guaranty.

          SECTION  4.14.  Limitation  on Asset Sales.  The Company will not, and
     will not permit any  Restricted  Subsidiary  to,  consummate any Asset Sale
     unless:

          (a) the  Company or such  Restricted  Subsidiary,  as the case may be,
     receives consideration at the time of such Asset Sale at least equal to the
     Fair Market Value of the Property subject to such Asset Sale; and

          (b) all of the  consideration  paid to the Company or such  Restricted
     Subsidiary in connection  with such Asset Sale is in the form of cash, cash
     equivalents,  Liquid Securities,  Exchange  Properties or the assumption by
     the purchaser of liabilities of the Company (other than  liabilities of the
     Company  that are by their  terms  subordinated  to the  10.25%  Notes)  or
     liabilities  of any  Subsidiary  Guarantor that made such Asset Sale (other
     than  liabilities  of a  Subsidiary  Guarantor  that  are  by  their  terms
     subordinated to such Subsidiary Guarantor's  Subsidiary Guaranty),  in each
     case  as a  result  of  which  the  Company  and its  remaining  Restricted
     Subsidiaries  are  no  longer  liable  for  such  liabilities   ("Permitted
     Consideration");  provided,  however,  that the Company and its  Restricted
     Subsidiaries  shall be permitted to receive  Property  other than Permitted
     Consideration,  so long as the  aggregate  Fair  Market  Value  of all such
     Property other than Permitted  Consideration  received from Asset Sales and
     held by the Company or any Restricted  Subsidiary at any one time shall not
     exceed 10.0% of Adjusted Consolidated Net Tangible Assets.

          The Net Available Cash from Asset Sales by the Company or a Restricted
     Subsidiary may be applied by the Company or such Restricted Subsidiary,  to
     the extent the Company or such Restricted Subsidiary elects (or is required
     by the terms of any Senior  Indebtedness  of the  Company  or a  Subsidiary
     Guarantor), to:

          (a) prepay,  repay or purchase Senior Indebtedness of the Company or a
     Subsidiary  Guarantor  (in each  case  excluding  Indebtedness  owed to the
     Company or an Affiliate of the Company);

          (b) 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);
     or

          (c)  purchase  10.25%  Notes or purchase  both 10.25% Notes and one or
     more series or issues of other Pari Passu  Indebtedness on a pro rata basis
     (excluding 10.25% Notes and Pari Passu  Indebtedness owed by the Company or
     an Affiliate of the Company).

          Any Net  Available  Cash from an Asset Sale not applied in  accordance
     with the  preceding  paragraph  within 365 days from the date of such Asset
     Sale shall  constitute  "Excess  Proceeds."  When the  aggregate  amount of
     Excess Proceeds exceeds $10.0 million, the Company will be required to make
     an offer to purchase  10.25%  Notes having an  aggregate  principal  amount
     equal to the aggregate amount of Excess Proceeds (the  "Prepayment  Offer")
     at a purchase  price equal to 100% of the  principal  amount of such 10.25%
     Notes plus accrued and unpaid  interest,  if any, to the Purchase  Date (as







                                                                              39

     defined) in  accordance  with the  procedures  (including  prorating in the
     event of oversubscription) set forth in the Indenture, but, if the terms of
     any  Pari  Passu  Indebtedness  require  that a Pari  Passu  Offer  be made
     contemporaneously with the Prepayment Offer, then the Excess Proceeds shall
     be  prorated  between  the  Prepayment  Offer and such Pari Passu  Offer in
     accordance with the aggregate  Outstanding  principal amounts of the 10.25%
     Notes and such Pari Passu Indebtedness,  and the aggregate principal amount
     of 10.25%  Notes for which the  Prepayment  Offer is made  shall be reduced
     accordingly.  If the aggregate principal amount of 10.25% Notes tendered by
     Holders thereof exceeds the amount of available Excess Proceeds,  then such
     Excess  Proceeds  will be allocated  pro rata  according  to the  principal
     amount of the 10.25% Notes  tendered and the Trustee will select the 10.25%
     Notes to be purchased in accordance with the Indenture.  To the extent that
     any portion of the amount of Excess Proceeds  remains after compliance with
     the second  sentence of this  paragraph  and  provided  that all Holders of
     10.25% Notes have been given the  opportunity  to tender their 10.25% Notes
     for purchase as described in the following paragraph in accordance with the
     Indenture,  the  Company  and its  Restricted  Subsidiaries  may  use  such
     remaining amount for purposes  permitted by the Indenture and the amount of
     Excess Proceeds will be reset to zero.

          Within 30 days  after the  365th  day  following  the date of an Asset
     Sale,  the Company  shall,  if it is obligated to make an offer to purchase
     the  10.25%  Notes  pursuant  to the  preceding  paragraph,  send a written
     Prepayment Offer notice,  by first-class mail, to the Holders of the 10.25%
     Notes (the  "Prepayment  Offer  Notice"),  accompanied by such  information
     regarding  the Company and its  Subsidiaries  as the Company  believes will
     enable such Holders of the 10.25% Notes to make an informed  decision  with
     respect to the Prepayment  Offer.  The Prepayment  Offer Notice will state,
     among other things:

          (a) that the Company is offering to purchase  10.25% Notes pursuant to
     the provisions of the Indenture;

          (b) that any 10.25% Note (or any portion thereof) accepted for payment
     (and duly paid on the Purchase Date) pursuant to the Prepayment Offer shall
     cease to accrue interest on the Purchase Date;

          (c) that any 10.25% Notes (or portions  thereof) not properly tendered
     will continue to accrue interest;

          (d) the purchase price and purchase  date,  which shall be, subject to
     any contrary  requirements of applicable law, no less than 30 days nor more
     than 60 days  after the date the  Prepayment  Offer  Notice is mailed  (the
     "Purchase Date");

          (e) the aggregate principal amount of 10.25% Notes to be purchased;

          (f) a description  of the procedure  that Holders of 10.25% Notes must
     follow in order to tender their 10.25% Notes for payment; and

          (g) all other  instructions and materials  necessary to enable Holders
     to tender 10.25% Notes pursuant to the Prepayment Offer.

     The Company will comply, to the extent applicable, with the requirements of
     Section  14(e)  under the  Exchange  Act and any other  securities  laws or
     regulations  thereunder  to  the  extent  such  laws  and  regulations  are







                                                                              40

     applicable  in  connection  with the  purchase of 10.25% Notes as described
     above.  To the  extent  that  the  provisions  of any  securities  laws  or
     regulations  conflict with the provisions relating to the Prepayment Offer,
     the Company will comply with the applicable securities laws and regulations
     and will not be deemed to have breached its obligations  described above by
     virtue thereof.

          SECTION  4.15.  Incurrence  of  Layered  Indebtedness.  The  Indenture
     provides that:

          (a) the Company will not Incur any  Indebtedness  that is subordinated
     or junior in right of  payment to any Senior  Indebtedness  of the  Company
     unless such  Indebtedness  constitutes  Indebtedness  that is junior to, or
     pari passu with, the 10.25% Notes in right of payment; and

          (b) no  Subsidiary  Guarantor  will  Incur  any  Indebtedness  that is
     subordinated  or junior in right of payment to any Senior  Indebtedness  of
     such Subsidiary Guarantor unless such Indebtedness constitutes Indebtedness
     that in right of payment is junior to, or pari passu with,  such Subsidiary
     Guarantor's Subsidiary Guaranty.

          SECTION 4.16. Limitation on Transactions with Affiliates.  The Company
     will  not,  and will not  permit  any of its  Restricted  Subsidiaries  to,
     directly or indirectly,  conduct any business or enter into any transaction
     or series of  transactions  (including  the  sale,  transfer,  disposition,
     purchase,  exchange or lease of Property, the making of any Investment, the
     giving of any  Guarantee or the  rendering of any service)  with or for the
     benefit of any Affiliate of the Company (other than the Company or a Wholly
     Owned Subsidiary), unless:

          (a) such transaction is set forth in writing;

          (b) such  transaction  or series of  transactions  is on terms no less
     favorable  to the  Company or such  Restricted  Subsidiary  than those that
     could be obtained in a comparable  arm's-length  transaction  with a Person
     that is not an Affiliate of the Company or such Restricted Subsidiary; and

          (c) with respect to a transaction or series of transactions  involving
     aggregate  payments  by or to the  Company  or such  Restricted  Subsidiary
     having a Fair Market Value equal to or in excess of:

          Directors of the Company  (including  a majority of the  disinterested
          members of such  Board of  Directors)  approves  such  transaction  or
          series of transactions  and certifies that such  transaction or series
          of  transactions  complies  with  clause  (b) of  this  paragraph,  as
          evidenced by a certified resolution delivered to the Trustee, or

                                                                              41

               recognized  investment  banking firm or appraisal firm, in either

               matter of the transaction (or series of transactions) at issue, a
               written opinion that such transaction (or series of transactions)
               is fair,  from a financial  point of view, to the Company or such
               Restricted Subsidiary, and

                    (B) such Board of  Directors  (including  a majority  of the
               disinterested  members of the Board of  Directors of the Company)
               approves such transaction or series of transactions and certifies

                    (B) relating to Indebtedness of a Restricted  Subsidiary and
               existing at the time it became a  Restricted  Subsidiary  if such

               Restricted Subsidiary became a Restricted Subsidiary, or

                    (C) that result from the renewal, refinancing,  extension or

               encumbrance or  restriction  is not materially  less favorable to
               the  Holders of 10.25%  Notes than those under or pursuant to the
               agreement so renewed, refinanced, extended or amended, and,

               (2) with respect to clause (c) only, to:







                                                                              43

                    (A) restrictions  relating to Indebtedness that is permitted
               to be Incurred and secured without also securing the 10.25% Notes
               under  Sections  4.10 and 4.11 and that limit the right the right
               of  the  debtor  to  dispose  of  the  Property   securing   such
               Indebtedness,

                    (B) any encumbrance or restriction applicable to Property at
               the  time  it  is  acquired  by  the  Company  or  a   Restricted
               Subsidiary,  so long as such  encumbrance or restriction  relates
               solely  to the  Property  so  acquired  and  was not  created  in
               anticipation of or in connection with such acquisition,

                    (C)   customary   provisions   restricting   subletting   or
               assignment of leases and customary provisions in other agreements

                    (D)   customary   restrictions   contained   in  asset  sale
               agreements  limiting  the  transfer  of such  assets  pending the
               closing of such sale.

          SECTION 4.18.  Future Subsidiary  Guarantors.  The Company shall cause
     each Restricted Subsidiary that:

          (a) Incurs  Indebtedness or issues Preferred Stock following the Issue
     Date; or

          (b) has  Indebtedness  or Preferred  Stock  outstanding on the date on
     which such Restricted Subsidiary becomes a Restricted Subsidiary,

     to execute  and deliver to the  Trustee a  Subsidiary  Guaranty at the time
     such Restricted Subsidiary Incurs such Indebtedness or becomes a Restricted
     Subsidiary; provided, however, that such Restricted Subsidiary shall not be
     required to deliver a Subsidiary  Guaranty if the aggregate  amount of such
     Indebtedness or Preferred Stock,  together with all other  Indebtedness and
     Preferred Stock then outstanding among Restricted Subsidiaries that are not
     Subsidiary Guarantors, is less than $10.0 million.

          SECTION 4.19. Restricted and Unrestricted Subsidiaries. Unless defined
     or  designated  as an  Unrestricted  Subsidiary,  any Person that becomes a
     Subsidiary of the Company or any of its  Restricted  Subsidiaries  shall be
     classified as a Restricted Subsidiary subject to the provisions of the next
     paragraph. The Company may designate a Subsidiary (including a newly formed
     or newly  acquired  Subsidiary)  of the  Company  or any of its  Restricted
     Subsidiaries as an Unrestricted Subsidiary if:

          (a) such  Subsidiary  does not at such time own any  Capital  Stock or
     Indebtedness of, or own or hold any Lien on any Property of, the Company or
     any other Restricted Subsidiary;

          (b) such  Subsidiary  does not at such time have any  Indebtedness  or
     other  obligations  that, if in default,  would result (with the passage of
     time or  notice  or  otherwise)  in a default  on any  Indebtedness  of the
     Company or any Restricted Subsidiary; and






                                                                              44


         (c)  (1) such designation is effective immediately upon such Subsidiary
     becoming a Subsidiary of the Company or of a Restricted Subsidiary,

               (2) the Subsidiary to be so designated has total assets of $1,000
          or less, or

               (3) if such Subsidiary has assets greater than $1,000,  then such
          redesignation as an Unrestricted  Subsidiary is deemed to constitute a
          Restricted  Payment in an amount equal to the Fair Market Value of the
          Company's direct and indirect  ownership  interest in such Subsidiary,
          and such Restricted  Payment would be permitted to be made at the time
          of such  designation  under  Section  4.12.  Except as provided in the
          immediately  preceding  sentence,  no  Restricted  Subsidiary  may  be
          redesignated  as an  Unrestricted  Subsidiary.  The  designation of an
          Unrestricted  Subsidiary or removal of such designation  shall be made
          by the  Board of  Directors  of the  Company  or a  committee  thereof
          pursuant to a certified  resolution delivered to the Trustee and shall
          be effective  as of the date  specified  in the  applicable  certified
          resolution,  which  shall  not be  prior to the  date  such  certified
          resolution is delivered to the Trustees.

     The  Company  will  not,  and  will  not  permit  any  of  its   Restricted
     Subsidiaries to, take any action or enter into any transaction or series of
     transactions that would result in a Person becoming a Restricted Subsidiary
     (whether through an acquisition or otherwise)  unless,  after giving effect
     to such  action,  transaction  or  series of  transactions,  on a pro forma
     basis:

          (a) the Company could Incur at least $1.00 of additional  Indebtedness
     pursuant to clause (a) of the first paragraph of Section 4.11 and

          (b) no Default or Event of Default would occur or be continuing.

          SECTION 4.20.  Change of Control.  Upon the  occurrence of a Change of
     Control,  each  Holder of 10.25%  Notes shall have the right to require the
     Company to repurchase all or any part (equal to $1,000 in principal  amount
     or an integral  multiple thereof) of such Holder's 10.25% Notes pursuant to
     the offer  described  below (the  "Change of Control  Offer") at a purchase
     price in cash equal to 101% of the  principal  amount of the  10.25%  Notes
     repurchased,  plus  accrued  and unpaid  interest,  if any,  to the date of
     purchase,  subject to the right of Holders of record on the relevant record
     date to receive  interest  due on the relevant  interest  payment date (the
     "Change of Control Payment").

     Within 30 days following any Change of Control, the Company shall:

          (a) cause a notice of the Change of Control  Offer to be sent at least
     once to the Dow Jones News Service or similar  business news service in the
     United States; and

          (b) send, by  first-class  mail,  with a copy to the Trustee,  to each
     Holder of 10.25%  Notes,  at such  Holder's  address  appearing in the Debt
     Security Register, a notice stating, among other things:

               (1) that a Change of Control has occurred and a Change of Control
          Offer is being  made  pursuant  to the  Indenture  and that all 10.25%
          Notes (or portions  thereof)  properly  tendered  will be accepted for
          payment,

               (2) the Change of Control  Purchase  Price and the purchase date,
          which shall be,  subject to any contrary  requirements  of  applicable
          law,  a business  day no  earlier  than 30 days nor later than 60 days
          from the date the Company  mails such  notice (the  "Change of Control
          Payment Date"),

               (3) that  any  10.25%  Note (or  portion  thereof)  accepted  for
          payment (and duly paid on the Change of Control Payment Date) pursuant
          to the Change of Control  Offer shall cease to accrue  interest on the
          Change of Control Payment Date,

               (4) that any 10.25%  Notes (or  portions  thereof)  not  properly
          tendered will continue to accrue interest,

               (5) a description of the transaction or transactions constituting
          the Change of Control,

               (6) the  procedures  that the  Holders of the  10.25%  Notes must
          follow in order to tender their 10.25% Notes (or portions thereof) for
          payment and the procedures that Holders of 10.25% Notes must follow in
          order to  withdraw an election  to tender  10.25%  Notes (or  portions
          thereof) for payment, and

               (7) all other  instructions  and  materials  necessary  to enable
          Holders  to tender  10.25%  Notes  pursuant  to the  Change of Control
          Offer.

          The  Company  will  comply,  to  the  extent   applicable,   with  the
     requirements  of  Section  14(e)  under  the  Exchange  Act and  any  other
     securities  laws and  regulations  thereunder  to the extent  such laws and
     regulations  are applicable in connection with the purchase of 10.25% Notes
     pursuant to a Change of Control Offer. To the extent that the provisions of
     any securities laws or regulations conflict with the provisions relating to
     the Change of Control  Offer,  the Company will comply with the  applicable
     securities laws and regulations and will not be deemed to have breached its
     obligations described above by virtue of such compliance.

          The Company  will not be  required  to make a Change of Control  Offer
     upon a Change of Control if a third party makes the Change of Control Offer
     in  the  manner,  at  the  times  and  otherwise  in  compliance  with  the
     requirements  set forth in the Indenture  applicable to a Change of Control
     Offer made by the Company and purchases  all 10.25% Notes validly  tendered
     and not withdrawn under such Change of Control Offer.

          Company")  shall be a Person  organized or existing  under the laws of
          the United  States of America,  any State  thereof or the  District of
          Columbia  and  the  Successor  Company  (if  not  the  Company)  shall
          expressly assume, by a supplemental indenture,  executed and delivered
          to  the  Trustee,  in  form  satisfactory  to  the  Trustee,  all  the
          obligations of the Company under the 10.25% Notes and the Indenture;

               (b) in the  case of a  conveyance,  transfer  or  lease of all or
          substantially  all the Company's  Property,  such Property  shall have
          been so conveyed, transferred or leased as an entirety or virtually as
          an entirety to one Person;

               (c)  immediately  after giving  effect to such  transaction  (and
          treating,  for  purposes  of this  clause (c) and  clauses (d) and (e)
          below,  any  Indebtedness  that becomes or is anticipated to become an
          obligation of the Successor Company or any Restricted  Subsidiary as a
          result of such  transaction  as having been Incurred by such Successor
          Company   or  such   Restricted   Subsidiary   at  the  time  of  such
          transaction),  no Default or Event of Default  shall have occurred and
          be continuing;

               (d)  immediately  after giving  effect to such  transaction,  the
          Successor  Company  would  be able to  Incur  an  additional  $1.00 of
          Indebtedness  pursuant  to  clause  (a) of the first  paragraph  under
          Section 4.11;

               (e)  immediately  after giving  effect to such  transaction,  the
          Successor  Company shall have Consolidated Net Worth in an amount that
          is not less than the Consolidated Net Worth of the Company immediately
          prior to such transaction; and

               (f) the Company shall have  delivered to the Trustee an Officer's
          Certificate,  stating that such consolidation,  merger or transfer and
          such supplemental indenture (if any) comply with the Indenture.







                                                                              49

          (b) Section 10.02 of the Original Indenture is amended by deleting the
     period at the end of the first sentence of the first paragraph  thereof and
     by substituting the following in its place:

          ";  provided,  however,  that  in  the  case  of a  lease  of  all  or
          substantially all of the Company's Property,  the Company shall not be
          released from any of the obligations or covenants under the Indenture,
          including  the  obligation to pay the principal of and interest on the
          Debt Securities."

          SECTION  9.  Applicability  of and  Amendments  to  Article  XI of the
     Original Indenture.

          (a) Article XI of the Original  Indenture  shall be  applicable to the
     10.25% Notes.

          (b) Section  11.02(b) of the  Original  Indenture is  superseded  with
     respect to the 10.25% Notes by the following provisions:

               (b) Subject to Sections  11.02(c)  and 11.03,  the Company at any
          time may terminate (i) all its obligations  under the 10.25% Notes and
          the  Indenture  with  respect to the 10.25% Notes  ("legal  defeasance
          option") or (ii) its  obligations  under  Sections 4.10,  4.11,  4.12,
          4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 10.01(d) and 10.01(e),
          the operation of Sections  6.01(d) (to the extent relating to Sections
          10.01(d) and  10.01(e)),  6.01(e) (to the extent  relating to Sections
          4.10,  4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20),
          6.01(f), 6.01(g) (to the extent relating to Significant Subsidiaries),
          6.01(h) (to the extent relating to Significant Subsidiaries),  6.01(j)
          and 6.01(k) ("covenant  defeasance option").  The Company may exercise
          its legal defeasance option  notwithstanding its prior exercise of its
          covenant defeasance option.

               If the Company exercises its legal defeasance option,  payment of
          the  10.25%  Notes  may not be  accelerated  because  of an  Event  of
          Default.  If the Company  exercises  its covenant  defeasance  option,
          payment of the 10.25% Notes may not be accelerated because of an Event
          of Default  specified in Sections 6.01(d) and 6.01(e) (with respect to
          the  provisions  of Articles 4 and 10  referred to in the  immediately
          preceding  paragraph)  and Sections  6.01(f),  6.01(g) and 6.01(h) (in
          each case to the extent relating to Significant Subsidiaries), 6.01(j)
          and 6.01(k).  If the Company  exercises its legal defeasance option or
          its covenant  defeasance option,  each Subsidiary  Guarantor,  if any,
          shall  be  released  from all its  obligations  under  its  Subsidiary
          Guarantee.

               Upon  satisfaction  of the  conditions  set forth herein and upon
          request of the Company,  the Trustee shall  acknowledge in writing the
          discharge of those obligations that the Company terminates.

          (c)  Section  11.02(c)  of the  Original  Indenture  is amended in its
     entirety with respect to the 10.25% Notes to read as follows:

               (c)  Notwithstanding  clauses  (a) and (b) above,  the  Company's
          obligations in Sections 2.07,  2.09,  4.02,  4.04,  5.01,  7.06, 7.08,
          7.10, 11.05, 11.06 and 11.07 shall survive until the 10.25% Notes have
          been paid in full.  Thereafter,  the Company's obligations in Sections
          7.06, 11.05 and 11.06 shall survive.






                                                                              50

               (d) Section  11.03(3)  of the  Original  Indenture  is amended by
          deleting  each instance of the number "91" and  substituting  "123" in
          its place.

               (e)  Section  11.07  of the  Original  Indenture  is  amended  by
          deleting the "." at the end thereof and by substituting  the following
          in its place:

          ;  provided,  however,  that,  if the  Company has made any payment of
          interest  on or  principal  of  any  Debt  Securities  because  of the
          reinstatement of its  obligations,  the Company shall be subrogated to
          the rights of the  Holders  of such Debt  Securities  to receive  such
          payment  from the  money or U.S.  Government  Obligations  held by the
          Trustee or paying agent.

          SECTION  10.  Applicability  of and  Amendments  to Article XII of the
     Original Indenture.

          (a) Article XII of the Original  Indenture  shall be applicable to the
     10.25% Notes.

          (b) Section 12.03 of the Original Indenture is amended in its entirety
     to read as follows:

          SECTION 12.03. Default on Senior Indebtedness. The Company may not pay
     the principal of, or premium, if any, or interest on, the Subordinated Debt
     Securities  or  make  any  deposit  pursuant  to  Article  XI and  may  not
     repurchase, redeem or otherwise retire (except, in the case of Subordinated
     Debt  Securities  that  provide for a mandatory  sinking  fund  pursuant to
     Section  3.04,  by the  delivery of  Subordinated  Debt  Securities  by the
     Company to the Trustee pursuant to the first paragraph of Section 3.05) any
     Subordinated  Debt Securities  (collectively,  "pay the  Subordinated  Debt
     Securities") if (i) any principal, premium or interest in respect of Senior
     Indebtedness is not paid within any applicable  grace period  (including at
     maturity) or (ii) any other default on Senior  Indebtedness  occurs and the
     maturity of such Senior  Indebtedness is accelerated in accordance with its
     terms unless,  in either case, (x) the default has been cured or waived and
     any such  acceleration  has been rescinded or (y) such Senior  Indebtedness
     has been paid in full in cash; provided,  however, that the Company may pay
     the  Subordinated  Debt  Securities  without regard to the foregoing if the
     Company and the Trustee receive written notice  approving such payment from
     the Representative of each issue of Designated Senior Indebtedness.  During
     the  continuance of any default  (other than a default  described in clause
     (i)  or  (ii)  of the  preceding  sentence)  with  respect  to  any  Senior
     Indebtedness  pursuant to which the  maturity  thereof  may be  accelerated
     immediately  without  further notice (except such notice as may be required
     to effect such  acceleration)  or the  expiration of any  applicable  grace
     periods,  the Company may not pay the  Subordinated  Debt  Securities for a
     period (a "Payment  Blockage  period")  commencing  upon the receipt by the
     Company  and the  Trustee  of  written  notice  of such  default  from  the
     Representative of any Designated Senior Indebtedness specifying an election
     to effect a Payment  Blockage  Period (a "Blockage  Notice") and ending 179
     days  thereafter (or earlier if such Payment  Blockage Period is terminated
     (i) by written  notice to the Trustee  and the  Company  from the Person or
     Persons who gave such Blockage Notice, (ii) by repayment in full in cash of
     such  Designated  Senior  Indebtedness  or (iii) because the default giving
     rise to such Blockage Notice is no longer continuing).  Notwithstanding the
     provisions described in the immediately  preceding sentence (but subject to
     the  provisions  contained in the first  sentence of this  Section  12.03),
     unless  the  holders  of  such  Designated   Senior   Indebtedness  or  the
     Representative of such  holders shall have accelerated the maturity of such






                                                                              51

     Designated  Senior  Indebtedness and not rescinded such  acceleration,  the
     Company may resume payments on the  Subordinated  Debt Securities after the
     end of such Payment Blockage Period.  Not more than one Blockage Notice may
     be given in any consecutive  360-day period,  irrespective of the number of
     defaults with respect to any number of issues of Senior Indebtedness during
     such period.

          (c) Section 12.04 of the Original Indenture is amended in its entirety
     to read as follows:

          SECTION 12.04.  Acceleration of Payment of Debt Securities. If payment
     of the  Subordinated  Debt  Securities is  accelerated  when any Designated
     Senior   Indebtedness  is   outstanding,   the  Company  may  not  pay  the
     Subordinated   Debt   Securities   until  three  Business  Days  after  the
     Representatives  of all issues of Designated  Senior  Indebtedness  receive
     notice of such acceleration and, thereafter,  may pay the Subordinated Debt
     Securities only if the Indenture otherwise permits payment at that time.

          SECTION 11. Subsidiary Guarantees.

          (a) The Original Indenture is amended with respect to the 10.25% Notes
     by adding Article XIV and Article XV as follows:

                                   ARTICLE XIV

                              Subsidiary Guarantees

          SECTION 14.01. Subsidiary Guarantees. Each Subsidiary Guarantor hereby
     unconditionally  Guarantees,  jointly and severally,  to each Holder and to
     the  Trustee  and its  successors  and  assigns  (a) the full and  punctual
     payment of principal of and interest on the 10.25% Notes when due,  whether
     at maturity,  by  acceleration,  by redemption or otherwise,  and all other
     monetary  obligations  of the Company  under the  Indenture and the 10.25%
     Notes and (b) the full and punctual  performance  within  applicable  grace
     periods of all other  obligations  of the Company under the  Indenture and
     the 10.25% Notes (all the foregoing being hereinafter  collectively  called
     the  "Obligations").  Each  Subsidiary  Guarantor  further  agrees that the
     Obligations may be extended or renewed, in whole or in part, without notice
     or further assent from such Subsidiary Guarantor,  and that such Subsidiary
     Guarantor  will remain  bound under this  Article XIV  notwithstanding  any
     extension or renewal of any Obligation.

          Each Subsidiary  Guarantor waives  presentation to, demand of, payment
     from and protest to the Company of any of the  Obligations  and also waives
     notice of protest for nonpayment.  Each Subsidiary  Guarantor waives notice
     of any Default under the 10.25% Notes or the  Obligations.  The obligations
     of each  Subsidiary  Guarantor  hereunder  shall not be affected by (a) the
     failure  of any  Holder or the  Trustee to assert any claim or demand or to
     enforce any right or remedy  against the Company or any other  Person under
     the Indenture,  the 10.25% Notes or any other  agreement or otherwise;  (b)
     any  extension  or  renewal of any  thereof;  (c) any  rescission,  waiver,
     amendment  or  modification  of any  of  the  terms  or  provisions  of the
     Indenture,  the 10.25% Notes or any other agreement; (d) the release of any
     security  held by any Holder or the Trustee for the  Obligations  or any of
     them; (e) the failure of any Holder or the Trustee to exercise any right or
     remedy against any other Guarantor of the Obligations; or (f) any change in
     the ownership of such Subsidiary Guarantor.






                                                                              52

          Each Subsidiary  Guarantor further agrees that its Subsidiary Guaranty
     herein constitutes a Guarantee of payment,  performance and compliance when
     due (and not a  Guarantee  of  collection)  and waives any right to require
     that any resort be had by any Holder or the  Trustee to any  security  held
     for payment of the Obligations.

          Each Subsidiary Guaranty is, to the extent and in the manner set forth
     in Article  XV,  subordinated  and subject in right of payment to the prior
     payment  in full of all Senior  Indebtedness  of the  Subsidiary  Guarantor
     giving such Subsidiary  Guaranty and each Subsidiary  Guarantor and is made
     subject to such provisions of the Indenture.

          Except as expressly set forth in Sections 4.13,  4.18, and 11.02,  the
     obligations of each Subsidiary  Guarantor hereunder shall not be subject to
     any  reduction,  limitation,  impairment  or  termination  for any  reason,
     including  any  claim  of  waiver,   release,   surrender,   alteration  or
     compromise,   and  shall  not  be  subject   to  any   defense  of  setoff,
     counterclaim,  recoupment  or  termination  whatsoever  or by reason of the
     invalidity, illegality or unenforceability of the Guaranteed Obligations or
     otherwise.   Without   limiting  the  generality  of  the  foregoing,   the
     obligations of each Subsidiary  Guarantor herein shall not be discharged or
     impaired or otherwise  affected by the failure of any Holder or the Trustee
     to assert any claim or demand or to enforce any remedy under the Indenture,
     the 10.25% Notes or any other  agreement,  by any waiver or modification of
     any thereof, by any Default, failure or delay, willful or otherwise, in the
     performance of the obligations, or by any other act or thing or omission or
     delay to do any other act or thing  which may or might in any  manner or to
     any extent vary the risk of such  Subsidiary  Guarantor or would  otherwise
     operate as a discharge of such  Subsidiary  Guarantor as a matter of law or
     equity.

          Each Subsidiary  Guarantor further agrees that its Subsidiary Guaranty
     herein shall continue to be effective or be reinstated, as the case may be,
     if at any time payment, or any part thereof, of principal of or interest on
     any  Obligation is rescinded or must otherwise be restored by any Holder or
     the  Trustee  upon the  bankruptcy  or  reorganization  of the  Company  or
     otherwise.

          In  furtherance  of the  foregoing  and not in limitation of any other
     right which any Holder or the  Trustee has at law or in equity  against any
     Subsidiary  Guarantor by virtue hereof,  upon the failure of the Company to
     pay the  principal  of or interest on any  Obligation  when and as the same
     shall become due, whether at maturity,  by  acceleration,  by redemption or
     otherwise,  or to  perform  or  comply  with  any  other  Obligation,  each
     Subsidiary  Guarantor  hereby promises to and will, upon receipt of written
     demand by the Trustee,  forthwith pay, or cause to be paid, in cash, to the
     Holders or the Trustee an amount equal to the sum of (i) the unpaid  amount
     of such  Obligations,  (ii) accrued and unpaid interest on such Obligations
     (but only to the extent not prohibited by law) and (iii) all other monetary
     Obligations of the Company to the Holders and the Trustee.

          Each Subsidiary  Guarantor agrees that it shall not be entitled to any
     right of subrogation in respect of any Obligations  Guaranteed hereby until
     payment in full in cash of all Obligations and all obligations to which the
     Obligations  are  subordinated  as provided in Article XV. Each  Subsidiary
     Guarantor  further  agrees  that,  as between it, on the one hand,  and the
     Holders  and the  Trustee,  on the  other  hand,  (x) the  maturity  of the
     Obligations  Guaranteed hereby may be accelerated as provided in Article VI
     for the purposes of such Subsidiary Guarantor's Subsidiary Guaranty herein,
     notwithstanding any stay,  injunction or other prohibition  preventing such







                                                                              53

     acceleration in respect of the Obligations  Guaranteed  hereby,  and (y) in
     the  event  of any  declaration  of  acceleration  of such  Obligations  as
     provided in Article VI, such  Obligations  (whether or not due and payable)
     shall forthwith become due and payable by such Subsidiary Guarantor for the
     purposes of this Section.

          Each  Subsidiary  Guarantor  also  agrees to pay any and all costs and
     expenses (including  reasonable attorneys' fees) incurred by the Trustee or
     any Holder in enforcing any rights under this Section 14.01.

          SECTION  14.02.  Contribution.  Each of the Company and any Subsidiary
     Guarantor (a "Contributing  Party") agrees (subject to Articles XII and XV)
     that,  in the  event  a  payment  shall  be made  by any  other  Subsidiary
     Guarantor  under any Subsidiary  Guaranty (the "Claiming  Guarantor"),  the
     Contributing  Party shall  indemnify  the  Claiming  Guarantor in an amount
     equal to the amount of such payment multiplied by a fraction, the numerator
     of which  shall  be the net  worth  of the  Contributing  Party on the date
     hereof and the denominator of which shall be the aggregate net worth of the
     Company and all the  Subsidiary  Guarantors  on the date hereof (or, in the
     case of any  Subsidiary  Guarantor  becoming  a party  hereto  pursuant  to
     Section  9.01(n),  the  determination of  indemnification  amounts shall be
     based upon net worth on the date of the supplemental indenture executed and
     delivered by such Subsidiary Guarantor.)

          SECTION  14.03.  Successors  and  Assigns.  This  Article XIV shall be
     binding upon each  Subsidiary  Guarantor and its successors and assigns and
     shall inure to the benefit of the successors and assigns of the Trustee and
     the Holders  and, in the event of any transfer or  assignment  of rights by
     any Holder or the Trustee,  the rights and  privileges  conferred upon that
     party in the Indenture and in the 10.25% Notes shall  automatically  extend
     to and be vested in such  transferee or assignee,  all subject to the terms
     and conditions of the Indenture.

          SECTION 14.04. No Waiver. Neither a failure nor a delay on the part of
     either  the  Trustee  or the  Holders in  exercising  any  right,  power or
     privilege  under this Article XIV shall  operate as a waiver  thereof,  nor
     shall a single or partial  exercise  thereof  preclude any other or further
     exercise  of any  right,  power or  privilege.  The  rights,  remedies  and
     benefits  of the Trustee and the Holders  herein  expressly  specified  are
     cumulative  and not  exclusive  of any other  rights,  remedies or benefits
     which either may have under this Article XIV at law, in equity,  by statute
     or otherwise.

          SECTION 14.05. Modification.  No modification,  amendment or waiver of
     any  provision of this Article XIV, nor the consent to any departure by any
     Subsidiary Guarantor therefrom,  shall in any event be effective unless the
     same shall be in writing and signed by the Trustee, and then such waiver or
     consent  shall  be  effective  only in the  specific  instance  and for the
     purpose for which given. No notice to or demand on any Subsidiary Guarantor
     in any case shall entitle such Subsidiary Guarantor to any other or further
     notice or demand in the same, similar or other circumstances.

     SECTION 14.06.  Execution of Supplemental  Indenture for Future  Subsidiary
     Guarantors.  Each  Subsidiary  which is  required  to  become a  Subsidiary
     Guarantor  pursuant to Section 4.18 shall  promptly  execute and deliver to
     the  Trustee  a  supplemental  indenture  in the form of  Exhibit  B hereto
     pursuant to which such Subsidiary shall become a Subsidiary Guarantor under
     this Article XIV and shall Guarantee the Obligations. Concurrently with the
     execution and delivery of such  supplemental  indenture,  the Company shall








                                                                              54

     deliver to the  Trustee  an  Opinion  of  Counsel  to the effect  that such
     supplemental indenture has been duly authorized,  executed and delivered by
     such  Subsidiary  and  that,  subject  to the  application  of  bankruptcy,
     insolvency, moratorium, fraudulent conveyance or transfer and other similar
     laws  relating to  creditors'  rights  generally  and to the  principles of
     equity,  whether  considered  in a  proceeding  at  law or in  equity,  the
     Subsidiary  Guaranty of such  Subsidiary  Guarantor  is a legal,  valid and
     binding obligation of such Subsidiary  Guarantor,  enforceable against such
     Subsidiary Guarantor in accordance with its terms.


                                   ARTICLE XV

                     Subordination of Subsidiary Guarantees

          SECTION 15.01.  Agreement To Subordinate.  Each  Subsidiary  Guarantor
     agrees,  and each  Holder  by  accepting  a 10.25%  Note  agrees,  that the
     Obligations  of such  Subsidiary  Guarantor  are  subordinated  in right of
     payment,  to the extent and in the manner  provided in this  Article XV, to
     the  payment  when  due of  all  Senior  Indebtedness  of  such  Subsidiary
     Guarantor and that the  subordination is for the benefit of and enforceable
     by the holders of such Senior Indebtedness. The Obligations of a Subsidiary
     Guarantor  shall in all  respects  rank pari passu  with any future  Senior
     Subordinated  Indebtedness of such  Subsidiary  Guarantor and senior to all
     existing and future junior  subordinated  Indebtedness  of such  Subsidiary
     Guarantor,   and  only  Senior   Indebtedness  shall  rank  senior  to  the
     Obligations of such Subsidiary  Guarantor in accordance with the provisions
     set forth herein.

          SECTION 15.02. Liquidation,  Dissolution, Bankruptcy. Upon any payment
     or distribution of the assets of any Subsidiary Guarantor to creditors upon
     a total or partial  liquidation  or a total or partial  dissolution of such
     Subsidiary  Guarantor  or  in  a  bankruptcy,  reorganization,  insolvency,
     receivership or similar proceeding relating to such Subsidiary Guarantor or
     its property:

                  (1)  holders  of  Senior   Indebtedness   of  such  Subsidiary
         Guarantor  shall be entitled to receive  payment in full of such Senior
         Indebtedness  before  holders  shall be entitled to receive any payment
         pursuant to any Obligations of such Subsidiary Guarantor; and

                  (2) until the Senior Indebtedness of any Subsidiary  Guarantor
         is  paid  in  full,  any  distribution  made  by or on  behalf  of such
         Subsidiary  Guarantor to which  Holders  would be entitled but for this
         Article  XV  shall  be made to  holders  of the  Senior  Debt as  their
         interests  may  appear,  except that all Holders may receive and retain
         shares of stock and any debt  securities of such  Subsidiary  Guarantor
         that  are  subordinated  to  Senior  Indebtedness  of  such  Subsidiary
         Guarantor  to at  least  the same  extent  as the  Obligations  of such
         Subsidiary  Guarantor are  subordinated to Senior  Indebtedness of such
         Subsidiary Guarantor.

          SECTION 15.03. Default on Senior Indebtedness of Subsidiary Guarantor.
     No  Subsidiary  Guarantor  may  make  any  payment  pursuant  to any of its
     Obligations or repurchase, redeem or otherwise retire or defease any 10.25%
     Notes or other Obligations (collectively, "pay its Subsidiary Guaranty") if
     (i) any Senior Indebtedness of such Subsidiary Guarantor is not paid within
     any  applicable  grace  period  (including  at  maturity) or (ii) any other







                                                                              55

     default on Senior Indebtedness of such Subsidiary  Guarantor occurs and the
     maturity of such Senior  Indebtedness is accelerated in accordance with its
     terms unless,  in either case, (x) the default has been cured or waived and
     any such  acceleration  has been rescinded or (y) such Senior  Indebtedness
     has been paid in full; provided, however, that any Subsidiary Guarantor may
     pay  its  Subsidiary  Guaranty  without  regard  to the  foregoing  if such
     Subsidiary  Guarantor and the Trustee receive written notice approving such
     payment from the  Representatives  of each issue of Senior  Indebtedness of
     such Subsidiary  Guarantor.  No Subsidiary Guarantor may pay its Subsidiary
     Guaranty  during the  continuance  of any  Payment  Blockage  Period  after
     receipt by the Company and the Trustee of a Payment  Blockage  Notice under
     Section 12.03.  Notwithstanding the provisions described in the immediately
     preceding  sentence,  unless  the  holders of Senior  Indebtedness  of such
     Subsidiary   Guarantor   giving  such  Payment   Blockage   Notice  or  the
     Representative  of such holders shall have accelerated the maturity of such
     Senior  Indebtedness  and not rescinded such  acceleration,  any Subsidiary
     Guarantor may resume (unless otherwise prohibited as described in the first
     sentence of this paragraph)  payments  pursuant to its Subsidiary  Guaranty
     after such Payment Blockage Period.

          SECTION 15.04.  Demand for Payment. If a demand for payment is made on
     a Subsidiary  Guarantor pursuant to Article XIV, such Subsidiary  Guarantor
     may not pay its  Subsidiary  Guaranty  until three  Business Days after the
     Representatives  of all issues of Senior  Indebtedness  of such  Subsidiary
     Guarantor receive notice of such acceleration and, thereafter,  may pay its
     Subsidiary Guaranty only if the Indenture otherwise permits payment at that
     time.

          SECTION 15.05.  When Distribution Must Be Paid Over. If a distribution
     is made to Holders  that  because  of this  Article XV should not have been
     made to them,  the Holders who  receive the  distribution  shall hold it in
     trust for holders of the relevant  Senior  Indebtedness  and pay it over to
     them or their Representatives as their interests may appear.

          SECTION  15.06.  Subrogation.  After  all  Senior  Indebtedness  of  a
     Subsidiary Guarantor is paid in full and until the 10.25% Notes are paid in
     full,  Holders  shall be  subrogated  to the  rights of  holders  of Senior
     Indebtedness to receive distributions applicable to Senior Indebtedness.  A
     distribution  made  under  this  Article  XV  to  holders  of  such  Senior
     Indebtedness  that  otherwise  would have been made to  Holders is not,  as
     between the relevant  Subsidiary  Guarantor and Holders,  a payment by such
     Subsidiary Guarantor on such Senior Indebtedness.

          SECTION 15.07.  Relative Rights.  This Article XV defines the relative
     rights of  Holders  and  holders  of Senior  Indebtedness  of a  Subsidiary
     Guarantor. Nothing in the Indenture shall:

                  (1) impair, as between a Subsidiary Guarantor and Holders, the
         obligation  of  such  Subsidiary  Guarantor,   which  is  absolute  and
         unconditional,  to pay the  Obligations  to the  extent  set  forth  in
         Article XIV or the relevant Subsidiary Guaranty; or

                  (2)  prevent the  Trustee or any Holder  from  exercising  its
         available  remedies upon a default by such  Subsidiary  Guarantor under
         the   Obligations,   subject   to  the  rights  of  holders  of  Senior
         Indebtedness  of such  Subsidiary  Guarantor  to receive  distributions
         otherwise payable to Holders.







                                                                              56

          SECTION  15.08.  Subordination  May  Not  Be  Impaired  by  Subsidiary
     Guarantor.  No right of any holder of Senior Indebtedness of any Subsidiary
     Guarantor to enforce the subordination of the Obligation of such Subsidiary
     Guarantor shall be impaired by any act or failure to act by such Subsidiary
     Guarantor or by its failure to comply with the Indenture.

          SECTION  15.09.  Rights of Trustee and Paying  Agent.  Notwithstanding
     Section 15.03, the Trustee or paying agent may continue to make payments on
     any  Subsidiary  Guaranty  and shall not be charged  with  knowledge of the
     existence  of facts that  would  prohibit  the making of any such  payments
     unless,  not less than two Business Days prior to the date of such payment,
     a responsible trust officer receives written notice satisfactory to it that
     payments may not be made under this  Article XV. The Company,  the relevant
     Subsidiary Guarantor,  the Registrar, any paying agent, a Representative or
     a holder of Senior  Indebtedness  of any Subsidiary  Guarantor may give the
     notice; provided,  however, that, if an issue of Senior Indebtedness of any
     Subsidiary Guarantor has a Representative, only the Representative may give
     the notice.

          The Trustee in its  individual  or any other  capacity may hold Senior
     Indebtedness with the same rights it would have if it were not Trustee. The
     Registrar  and any  paying  agent  may do the same with  like  rights.  The
     Trustee  shall be entitled  to all the rights set forth in this  Article XV
     with respect to any Senior  Indebtedness  of any Subsidiary  Guarantor that
     may at any time be held by it, to the same  extent  as any other  holder of
     Senior Indebtedness; and nothing in Article XV shall deprive the Trustee of
     any of its rights as such holder. Nothing in this Article XV shall apply to
     claims of, or payments to, the Trustee under or pursuant to Section 7.06.

          SECTION 15.10.  Distribution or Notice to  Representative.  Whenever a
     distribution  is  to be  made  or a  notice  given  to  holders  of  Senior
     Indebtedness of any Subsidiary Guarantor,  the distribution may be made and
     the notice given to their Representative (if any).

          SECTION  15.11.  Article XV Not To Prevent  Events of Default  Under a
     Subsidiary Guaranty or Limit Right To Demand Payment. The failure to make a
     payment  pursuant to a  Subsidiary  Guaranty by reason of any  provision in
     this Article XV shall not be construed as  preventing  the  occurrence of a
     Default under such  Subsidiary  Guaranty.  Nothing in this Article XV shall
     have any effect on the right of the Holders or the Trustee to make a demand
     for  payment on any  Subsidiary  Guarantor  pursuant  to Article XIV or the
     relevant Subsidiary Guaranty.

          SECTION  15.12.   Trustee  Entitled  To  Rely.  Upon  any  payment  or
     distribution pursuant to this Article XV, the Trustee and the Holders shall
     be  entitled  to rely (i) upon any order or decree of a court of  competent
     jurisdiction  in which any proceedings of the nature referred to in Section
     15.02 are pending,  (ii) upon a certificate of the  liquidating  trustee or
     agent or other Person making such payment or distribution to the Trustee or
     to the Holders or (iii) upon the  Representatives for the holders of Senior
     Indebtedness  of any Subsidiary  Guarantor for the purpose of  ascertaining
     the Persons  entitled to participate in such payment or  distribution,  the
     holders of Senior  Indebtedness  and other  Indebtedness of such Subsidiary
     Guarantor,  the amount  thereof or payable  thereon,  the amount or amounts
     paid or  distributed  thereon and all other facts  pertinent  thereto or to
     this Article XV. In the event that the Trustee  determines,  in good faith,
     that  evidence  is  required  with  respect to the right of any Person as a







                                                                              57

     holder of Senior Indebtedness of any Subsidiary Guarantor to participate in
     any payment or  distribution  pursuant to this  Article XV, the Trustee may
     request such Person to furnish  evidence to the reasonable  satisfaction of
     the  Trustee as to the  amount of Senior  Indebtedness  of such  Subsidiary
     Guarantor held by such Person,  the extent to which such Person is entitled
     to participate in such payment or distribution and other facts pertinent to
     the rights of such Person under this  Article XV, and, if such  evidence is
     not  furnished,  the Trustee  may defer any payment to such Person  pending
     judicial  determination  as to the  right of such  Person to  receive  such
     payment.  The  provisions  of Sections 7.01 and 7.02 shall be applicable to
     all actions or omissions of actions by the Trustee pursuant to this Article
     XV.

          SECTION  15.13.  Trustee To Effectuate  Subordination.  Each Holder by
     accepting a 10.25% Note authorizes and directs the Trustee on his behalf to
     take such action as may be  necessary  or  appropriate  to  acknowledge  or
     effectuate the subordination  between the Holders and the holders of Senior
     Indebtedness of any Subsidiary Guarantor as provided in this Article XV and
     appoints the Trustee as attorney-in-fact for any and all such purposes.

          SECTION   15.14.   Trustee  Not   Fiduciary   for  Holders  of  Senior
     Indebtedness  of Subsidiary  Guarantor.  The Trustee shall not be deemed to
     owe any  fiduciary  duty  to the  holders  of  Senior  Indebtedness  of any
     Subsidiary  Guarantor  and shall not be  liable to any such  holders  if it
     shall  mistakenly  pay over or  distribute to Holders or the Company or any
     other  Person,  money  or  assets  to  which  any  holders  of such  Senior
     Indebtedness shall be entitled by virtue of this Article XV or otherwise.

          SECTION  15.15.   Reliance  by  Holders  of  Senior   Indebtedness  on
     Subordination   Provisions.   Each  Holder  by   accepting  a  10.25%  Note
     acknowledges  and agrees that the foregoing  subordination  provisions are,
     and are intended to be, an inducement and a consideration to each holder of
     any Senior  Indebtedness of any Subsidiary  Guarantor,  whether such Senior
     Indebtedness  was created or acquired  before or after the  issuance of the
     10.25% Notes, to acquire and continue to hold, or to continue to hold, such
     Senior  Indebtedness and such holder of Senior Indebtedness shall be deemed
     conclusively to have relied on such  subordination  provisions in acquiring
     and continuing to hold, or in continuing to hold, such Senior Indebtedness.

          SECTION 12. Governing Law. This First  Supplemental  Indenture and the
     10.25%  Notes shall be governed by and  construed  in  accordance  with the
     internal  laws of the State of New York but  without  giving  effect to the
     applicable   principles  of  conflicts  of  law  to  the  extent  that  the
     application of the laws of another  jurisdiction would be required thereby.
     The Trustee,  the Company,  each of the Guarantors and the Holders agree to
     submit to the  jurisdiction  of the  courts of the State of New York in any
     action or  proceeding  arising out of or relating to the  Indenture  or the
     10.25% Notes.

          SECTION 13.  Counterparts.  This First  Supplemental  Indenture may be
     executed in any number of counterparts,  each of which shall be an original
     but  such  counterparts  shall  together  constitute  but one and the  same
     instrument.


     IN WITNESS WHEREOF,  the parties hereto have caused this First Supplemental
Indenture to be duly executed as of the day and year first above written.

                    10.25% Senior Subordinated Notes due 2009


1.  Indenture; Limitations.

     The Company issued the 10.25% Notes under an Indenture dated as of July 29,
1999 (the "Original  Indenture") and a First Supplemental  Indenture dated as of
August  4, 1999 (the  "Supplemental  Indenture")  (the  Original  Indenture,  as
supplemented by the Supplemental  Indenture being hereinafter referred to as the
"Indenture"),   between  the  Company  and  Bank  One,  N.A.,  as  trustee  (the
"Trustee"). Capitalized terms herein are used as defined in the Indenture unless
otherwise  indicated.  The terms of the 10.25% Notes include those stated in the
Indenture  and  those  made  part of the  Indenture  by  reference  to the Trust
Indenture  Act. The 10.25% Notes are subject to all such terms,  and Holders are
referred to the  Indenture  and the Trust  Indenture  Act for a statement of all
such  terms.  To the extent  permitted  by  applicable  law, in the event of any
inconsistency  between  the  terms  of this  10.25%  Note  and the  terms of the
Indenture, the terms of the Indenture shall control.

     The 10.25%  Notes are  unsecured  senior  subordinated  obligations  of the
Company  limited  to  $225,000,000  aggregate  principal  amount at any one time
outstanding  (subject to Sections 2.03 and 2.10 of the  Indenture).  The Company
may, subject to Article IV of the Indenture, issue Additional 10.25% Notes under
the Indenture.  This 10.25% Note is one of the Original 10.25% Notes referred to
in the Indenture issued in an aggregate  principal  amount of $125,000,000.  The
10.25% Notes include the Original 10.25% Notes and up to an aggregate  principal
amount of  $100,000,000  Additional  10.25%  Notes that may be issued  under the
Indenture. The Original 10.25% Notes and the Additional 10.25% Notes are treated
as a single class of Debt Securities under the Indenture.

2.   Principal and Interest.

     The Company will pay the principal of this 10.25% Note on August 1, 2009.

     The Company promises to pay interest on the principal amount of this 10.25%
Note on each February 1 and August 1 (each an "Interest  Payment Date"),  as set
forth below, at the rate per annum shown above.

     Interest  will be  payable  semiannually  (to the  holders of record of the
10.25%  Notes at the close of business on the January 16 or July 16  immediately
preceding the Interest Payment Date) on each Interest  Payment Date,  commencing
February 1, 2000.

     Interest on the 10.25% Notes will accrue from the most recent date to which
interest  has been paid or, if no interest  has been paid,  from August 4, 1999,
provided  that,  if there is no existing  Default in the payment of interest and
this 10.25% Note is  authenticated  between a Regular Record Date referred to on
the face hereof and the next succeeding  Interest  Payment Date,  interest shall







                                                                               4

accrue from such Interest  Payment Date.  Interest will be computed on the basis
of a 360-day year of twelve 30-day months.

     The Company  shall pay  interest on overdue  principal at the rate borne by
the  10.25%  Notes  plus 1% per  annum,  and it shall pay  interest  on  overdue
installments of interest,  to the extent lawful, at the rate borne by the 10.25%
Notes.

3.  Method of Payment.

     The Company will pay interest (except defaulted  interest) on the principal
amount of the 10.25% Notes as provided  above on each  Interest  Payment Date to
the persons who are Holders (as reflected in the Debt  Security  Register at the
close of  business  on the  January  16 and July 16  immediately  preceding  the
relevant  Interest  Payment  Date),  in each case,  even if the  10.25%  Note is
canceled on  registration of transfer,  registration of exchange,  redemption or
repurchase  after such record date and on or before the Interest  Payment  Date,
provided that,  with respect to the payment of principal,  the Company will make
payment to the Holder that  surrenders  this 10.25% Note to a paying agent on or
after August 1, 2009.

     The Company will pay  principal,  premium,  if any, and as provided  above,
interest  in money of the  United  States  that at the time of  payment is legal
tender for payment of public and private  debts.  However,  the Company,  at its
option, may pay principal, premium, if any, and interest by its check payable in
such money. It may mail an interest check to a Holder's  registered  address (as
reflected in the Debt  Security  Register).  Payments in respect of 10.25% Notes
represented by a Global  Security  (including  principal,  premium and interest)
will be made by wire  transfer of  immediately  available  funds to the accounts
specified by The  Depository  Trust  Company.  If a payment date is a date other
than a Business Day at a place of payment,  payment may be made at that place on
the next  succeeding day that is a Business Day and no interest shall accrue for
the intervening period.

4.  Paying Agent and Registrar.

     Initially,  the Trustee will act as authenticating  agent, paying agent and
Registrar.  The Company may change any  authenticating  agent,  paying  agent or
Registrar without notice. The Company, any Subsidiary or any Affiliate of any of
them may act as paying agent, Registrar or co-Registrar.

5.  Optional Redemption.

     Except as set forth in the following  paragraph,  the 10.25% Notes will not
be redeemable at the option of the Company prior to August 1, 2004.  Starting on
that date,  the Company  may redeem all or any portion of the 10.25%  Notes upon
not less than 30 nor more than 60 days' prior notice,  at the redemption  prices
set forth below,  plus accrued and unpaid  interest,  if any, to the  redemption
date  (subject to the right of Holders of record on the relevant  record date to
receive  interest due on the relevant  Interest  Payment  Date).  The  following
prices are for 10.25% Notes redeemed  during the 12-month  period  commencing on
August 1 of the years set forth  below,  and are  expressed  as  percentages  of
principal amount:







                                                                               5

                 Year                 Price
           ------------------        ---------
               2004                   105.125%
               2005                   103.417%
               2006                   101.708%
               2007 and thereafter    100.000%


     The  Company  may on any one or more  occasions  prior to August  1,  2002,
redeem  up to 33 1/3% of the  aggregate  principal  amount of the  10.25%  Notes
originally  issued with the net proceeds of one or more Equity  Offerings of the
Company at a redemption price of 110.25% of the principal  amount thereof,  plus
accrued and unpaid interest,  if any, to the date of redemption  (subject to the
right of Holders of record on the relevant  record date to receive  interest due
on the relevant  Interest  Payment Date),  provided that at least 66 2/3% of the
aggregate  principal  amount  of the  10.25%  Notes  originally  issued  remains
Outstanding  after the occurrence of such redemption.  Any such redemption shall
occur not later  than 90 days after the date of the  closing of any such  Equity
Offering  upon  not  less  than  30 or more  than 60  days'  prior  notice.  The
redemption  shall  be  made in  accordance  with  procedures  set  forth  in the
Indenture.

     If less than all the 10.25% Notes are to be redeemed at any time, selection
of 10.25% Notes for  redemption  will be made by the Trustee in compliance  with
the requirements of the principal national securities exchange, if any, on which
the 10.25% Notes are listed, or, if the 10.25% Notes are not so listed, on a pro
rata  basis,  by lot or by such  method  as the  Trustee  shall  deem  fair  and
appropriate.

6.  Sinking Fund

     The 10.25% Notes are not subject to any sinking fund.

7.  Subordination

     The 10.25% Notes are subordinated to Senior Indebtedness of the Company. To
the extent provided in the Indenture, Senior Indebtedness of the Company must be
paid  before the  10.25%  Notes may be paid.  The  Company  and each  Subsidiary
Guarantor  agrees,  and each Holder by  accepting a 10.25% Note  agrees,  to the
subordination  provisions  contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

8.     Repurchase upon a Change of Control.

     Upon the  occurrence  of a Change of Control,  each Holder of 10.25%  Notes
shall have the right to require the Company to repurchase all or any part (equal
to $1,000 in principal amount or an integral  multiple thereof) of such Holder's
10.25% Notes pursuant to the Change of Control Offer as provided in, and subject
to the terms of, the Indenture at a purchase  price in cash equal to 101% of the
principal  amount of the  10.25%  Notes  repurchased,  plus  accrued  and unpaid
interest,  if any, to the date of  purchase  (subject to the right of Holders of
record on the  relevant  record  date to receive  interest  due on the  relevant
Interest Payment Date).






                                                                               6

9.     Denominations; Transfer; Exchange.

     The 10.25% Notes are in registered form without coupons in denominations of
$1,000 of principal  amount and multiples of $1,000 in excess thereof.  A Holder
may register the  transfer or exchange of 10.25%  Notes in  accordance  with the
Indenture.  The Registrar may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not register
the transfer or exchange of any 10.25% Notes selected for redemption  (except in
the case of a 10.25% Note  redeemed in part,  the portion of the 10.25% Note not
to be  redeemed).  Also,  it need not  register  the transfer or exchange of any
10.25%  Notes for a period of 15 days  before the day of the mailing of a notice
of  redemption  of 10.25%  Notes  selected for  redemption  or 15 days before an
Interest Payment Date.

10.    Persons Deemed Owners.

     A Holder shall be treated as the owner of a 10.25% Note for all purposes.

11.    Unclaimed Money.

     If money for the payment of principal, premium, if any, or interest remains
unclaimed  for two years,  the Trustee  and the paying  agent will pay the money
back to the Company at its written request.  After that, Holders entitled to the
money must look to the Company for  payment,  unless an  abandoned  property law
designates  another  Person,  and all  liability  of the Trustee and such paying
agent with respect to such money shall cease.

12.    Discharge Prior to Redemption or Maturity.

     Subject to certain  conditions,  if the Company  deposits  with the Trustee
money or U.S.  Government  Obligations  sufficient  to pay the then  outstanding
principal  of,  premium,  if any,  and accrued  interest on the 10.25%  Notes to
redemption  or  maturity,   as  applicable,   the  Company  and  the  Subsidiary
Guarantors,  if any, may terminate some of or all of their obligations under the
Indenture  and the 10.25%  Notes,  except in certain  circumstances  for certain
sections thereof.

13.    Amendment; Supplement; Waiver.

     Subject to certain  exceptions,  the  Indenture  or the 10.25% Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in  principal  amount of the 10.25%  Notes then  Outstanding,  and any  existing
Default or  compliance  with any provision may be waived with the consent of the
Holders  of at least a majority  in  principal  amount of the 10.25%  Notes then
Outstanding. Without notice to or the consent of any Holder, the parties thereto
may amend or  supplement  the  Indenture  or the 10.25%  Notes to,  among  other
things,  cure any ambiguity,  defect or  inconsistency  and make any change that
does not adversely affect the rights of any Holder.

14.    Restrictive Covenants.

     The Indenture imposes certain limitations on the ability of the Company and
its  Restricted   Subsidiaries,   among  other  things,   to  Incur   additional
Indebtedness,  make  Restricted  Payments,  use the  proceeds  from Asset Sales,







                                                                               7

engage  in  transactions  with  Affiliates,  suffer  to exist  or  incur  Liens,

the end of each  fiscal  year,  the  Company  shall  deliver  to the  Trustee an
Officers'  Certificate stating whether or not the signers know of any Default or
Event of Default under such restrictive covenants.

15.    Successor Persons.

     Subject to certain  exceptions,  when a  successor  Person or other  entity
assumes all the  obligations of its  predecessor  under the 10.25% Notes and the
Indenture, the predecessor Person will be released from those obligations.

16.    Defaults and Remedies.

     The following  are summaries of Events of Default under the Indenture  with
respect to the 10.25% Notes:

          (a)  failure  to pay  any  interest  on the  10.25%  Notes  when  due,
     continued for 30 days;

          (b) failure to pay  principal of (or  premium,  if any, on) the 10.25%
     Notes when due;

          (c) failure to comply with Article X;

          (d)  failure  to  perform  any other  covenant  of the  Company or any
     Subsidiary Guarantor in the Indenture,  continued for 30 days after written
     notice to the  Company  from the  Trustee or the Holders of at least 25% in
     aggregate principal amount of the Outstanding 10.25% Notes;

          (e) a default by the Company or any  Restricted  Subsidiary  under any
     Indebtedness  for borrowed  money in an aggregate  amount greater than $5.0
     million (other than Non-recourse  Purchase Money Indebtedness) that results
     in acceleration of the maturity of such Indebtedness, or failure to pay any
     such  Indebtedness at maturity,  if such  Indebtedness is not discharged or
     such acceleration is not rescinded or annulled within 10 days after written
     notice as provided in the Indenture;

          (f) one or more  final  judgments  or orders  by a court of  competent
     jurisdiction  are entered against the Company or any Restricted  Subsidiary
     in an uninsured or unindemnified  aggregate amount  outstanding at any time
     in excess of $5.0 million and such judgments or orders are not  discharged,
     waived, stayed, satisfied or bonded for a period of 30 consecutive days;

          (g) certain events of bankruptcy,  insolvency or  reorganization  with
     respect to the Company or any Significant Subsidiary; or

          (h) a Subsidiary Guaranty ceases to be in full force and effect (other
     than in  accordance  with the terms of the  Indenture  and such  Subsidiary







                                                                               8

     Guaranty) or a Subsidiary  Guarantor  denies or disaffirms its  obligations
     under its Subsidiary Guaranty.

     The Indenture  provides that if an Event of Default (other than an Event of
Default  described  in clause (g) above) with respect to the 10.25% Notes at the
time  Outstanding  shall  occur and be  continuing,  either  the  Trustee or the
Holders of at least 25% in aggregate  principal amount of the Outstanding 10.25%
Notes by notice as provided in the Indenture may declare the principal amount of
the  10.25%  Notes to be due and  payable  immediately.  If an Event of  Default
described  in clause  (g) above with  respect  to the  10.25%  Notes at the time
Outstanding  shall  occur,  the  principal  amount of all the 10.25%  Notes will
automatically,  and  without  any action by the  Trustee or any  Holder,  become
immediately due and payable. After any such acceleration,  but before a judgment
or decree based on acceleration, the Holders of at least a majority in aggregate
principal   amount  of  the   Outstanding   10.25%  Notes  may,   under  certain
circumstances,  rescind  and annul such  acceleration  if all Events of Default,
other than the nonpayment of accelerated  principal (or other specified amount),
have been cured or waived as provided in the Indenture.

     Subject to the  provisions of the  Indenture  relating to the duties of the
Trustee,  in case of an Event of  Default  shall  occur and be  continuing,  the
Trustee  will be under no  obligation  to  exercise  any of its rights or powers
under the  Indenture  at the request or  direction  of any of the Holders of the
10.25% Notes,  unless such Holders shall have offered to the Trustee  reasonable
indemnity.  Subject to such provisions for the  indemnification  of the Trustee,
the  Holders  of at  least a  majority  in  aggregate  principal  amount  of the
Outstanding  10.25%  Notes  will have the right to direct  the time,  method and
place of conducting any  proceeding  for any remedy  available to the Trustee or
exercising  any trust or power  conferred  on the  Trustee  with  respect to the
10.25% Notes.

     No Holder of 10.25% Notes will have any right to institute  any  proceeding
with  respect  to the  Indenture,  or for the  appointment  of a  receiver  or a
trustee, or for any other remedy thereunder, unless:

          (a) such Holder has previously  given to the Trustee written notice of
     a continuing Event of Default with respect to the 10.25% Notes;

          (b) the Holders of at least 25% in aggregate  principal  amount of the
     Outstanding  10.25%  Notes have made  written  request,  and such Holder or
     Holders have  offered  reasonable  indemnity,  to the Trustees to institute
     such proceeding as trustee; and

          (c) the Trustee has failed to institute  such  proceeding  and has not
     received  from the  Holders of at least a majority in  aggregate  principal
     amount of the Outstanding  10.25% Notes a direction  inconsistent with such
     request, within 60 days after such notice, request and offer.

     However,  such limitations do not apply to a suit instituted by a Holder of
     10.25%  Notes for the  enforcement  of payment of the  principal  of or any
     premium or  interest on such 10.25%  Notes on or after the  applicable  due
     date specified in such 10.25% Notes.







                                                                               9

17. Trustee Dealings with the Company or the Guarantors.

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

18.    No Recourse Against Others.

     No incorporator or any past, present or future partner, shareholder,  other
equity holder, officer, director, employee or controlling Person as such, of the
Company or the  Guarantors or of any  successor  Person shall have any liability
for any  obligations of the Company or the Guarantors  under the 10.25% Notes or
the  Indenture  or for any claim  based on, in respect of or by reason of,  such
obligations or their creation.  Each Holder by accepting a 10.25% Note expressly
waives and releases all such  liability.  The waiver and release are a condition
of, and part of the consideration for the issuance of the 10.25% Notes.

19.    Authentication.

     This 10.25%  Note shall not be valid  until the  Trustee or  authenticating
agent signs the certificate of  authentication  on the other side of this 10.25%
Note.

20.    Abbreviations.

     Customary abbreviations may be used in the name of a Holder 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).

21.    Governing Law.

     THIS 10.25% NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE
INTERNAL  LAWS OF THE STATE OF NEW YORK BUT WITHOUT  GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

22.  CUSIP Numbers

     Pursuant  to a  recommendation  promulgated  by the  Committee  on  Uniform
Security Identification  Procedures,  the Company has caused CUSIP numbers to be
printed on the 10.25% Notes and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders.  No representation is made as
to the  accuracy  of such  numbers  either as printed on the 10.25%  Notes or as
contained  in any notice of  redemption  and  reliance may be placed only on the
other identification numbers placed thereon.








                                                                              10
