Arch Coal Trust No. 1998-1                        Lease Intended as Security


                                    Article I

                                   Definitions

     In this  Lease  and each  other  Operative  Document,  unless  the  context
otherwise requires:

          (a) any term  defined  below by  reference  to another  instrument  or
     document shall continue to have the meaning ascribed thereto whether or not
     such other instrument or document remains in effect;

          (b) words importing the singular include the plural and vice versa;

          (c) words importing a gender include any gender;

          (d) a  reference  to a part,  clause,  section,  article,  exhibit  or
     schedule  is a  reference  to a part,  clause,  section and article of, and
     exhibit and schedule to, such Operative Document;

          (e) a reference to any statute, regulation, proclamation, ordinance or
     law includes all statutes, regulations,  proclamations,  ordinances or laws
     amending,  supplementing,  supplanting, varying, consolidating or replacing
     them, and a reference to a statute includes all regulations,  proclamations
     and ordinances issued or otherwise applicable under that statute;

          (f) a reference to a document includes any amendment or supplement to,
     or replacement or novation of, that document;

          (g) a  reference  to a  party  to a  document  includes  that  party's
     successors and permitted assigns;

          (h) a reference to "including"  means including  without  limiting the
     generality of any  description  preceding such term and for purposes hereof
     the rule of  ejusdem  generis  shall not be  applicable  to limit a general
     statement followed by or referable to an enumeration of specific matters to
     matters similar to those specifically mentioned; and

          (i) except as  otherwise  provided  in the  Operative  Documents,  all
     computations and  determinations  as to accounting or financial matters and
     all  financial  statements  to  be  delivered  pursuant  to  the  Operative
     Documents  shall be made and prepared in  accordance  with GAAP  (including
     principles  of  consolidation  where  appropriate),  and all  accounting or
     financial  terms  shall have the  meanings  ascribed to such terms by GAAP;
     provided,  however,  that all  accounting  terms  used in Article IV of the
     Parent  Guaranty  (and all  defined  terms  used in the  definition  of any
     accounting  term used in Article IV of the Parent  Guaranty  shall have the
     meaning given to such terms (and defined  terms) under GAAP as in effect on
     the date hereof applied on a basis  consistent with those used in preparing
     the  financial  information  referred to in clause (p) of Article IV of the
     Parent Guaranty.  In the event of any change after the date hereof in GAAP,
     and if such change  would result in the  inability to determine  compliance
     with the financial covenants set forth in Article IV of the Parent Guaranty
     based upon Parent Guarantor's  regularly  prepared financial  statements by
     reason  of the  preceding  sentence,  then  the  parties  hereto  agree  to
     endeavor,  in good  faith,  to agree upon an  amendment  to this Lease that
     would adjust such financial covenants in a manner that would not affect the
     substance thereof, but would allow compliance therewith to be determined in
     accordance with Parent Guarantor's financial statements at that time.

     Further,  each of the parties to the Operative  Documents and their counsel
have  reviewed  and revised the  Operative  Documents,  or  requested  revisions

preferences or distinction among them.

     (c) If and to the  extent  that any Lessee  shall fail to make any  payment
with  respect to any of the  obligations  hereunder as and when due then in each
such  event,  the other  Lessees  will make such  payment  with  respect to such
obligation.

     (d) The obligations of each Lessee under the provisions of this Section 4.8
constitute full recourse  obligations of such Lessee,  enforceable against it to
the full extent of its  properties  and assets,  irrespective  of the  validity,
regularity  or  enforceability   of  this  Lease  or  any  other   circumstances
whatsoever.

     (e) Except as  otherwise  expressly  provided  herein,  each Lessee  hereby
waives  notice  of  acceptance  of its joint and  several  liability,  notice of
occurrence  of any Incipient  Default or Event of Default  (except to the extent

time taken or omitted by Lessor or any Certificate Purchaser under or in respect

any  extension  or  postponement  of the  time  for  the  payment  of any of the
Obligations  hereunder,  the  acceptance  of any partial  payment  thereon,  any
waiver,  consent or other action or  acquiescence  by Lessor or any  Certificate
Purchaser  at any time or times in respect  of any  default by any Lessee in the
performance or  satisfaction  of any term,  covenant,  condition or provision of
this  Lease,  any  and  all  other  indulgences  whatsoever  by  Lessor  or  any
Certificate  Purchaser in respect of any of the Obligations  hereunder,  and the
taking,  addition,  substitution or release, in whole or in part, at any time or
times, of any security for any of such Obligations or the addition, substitution
or release, in whole or in part, of any Lessee.  Without limiting the generality
of the foregoing,  each Lessee assents to any other action or delay in acting or
any  failure  to  act on the  part  of  Lessor  or  any  Certificate  Purchaser,
including,  without limitation, any failure strictly or diligently to assert any
right or to pursue  any  remedy  or to  comply  fully  with  applicable  laws or
regulations  hereunder which might,  but for the provisions of this Section 4.8,
afford grounds for terminating,  discharging or relieving such Lessee,  in whole
or in part,  from any of its  obligations  under this  Section 4.8, it being the
intention  of each  Lessee  that,  so long as any of the  Obligations  hereunder
remain unsatisfied,  the obligations of such Lessee under this Section 4.8 shall
not be  discharged  except by  performance  and then only to the  extent of such
performance.  The obligations of each Lessee under this Section 4.8 shall not be
diminished  or  rendered   unenforceable  by  any  winding  up,  reorganization,
arrangement,  liquidation,  reconstruction or similar proceeding with respect to
any  Lessee or  Lessor  or any  Certificate  Purchaser.  The  joint and  several
liability  of  Lessees  hereunder  shall  continue  in  full  force  and  effect
notwithstanding  any  absorption,  merger,  amalgamation  or  any  other  change
whatsoever in the name,  membership,  constitution  or place of formation of any
Lessee or Lessor or any Certificate Purchaser.

     (f) The  provisions  of this Section 4.8 are made for the benefit of Lessor
and Certificate  Purchasers and their respective successors and assigns, and may
be enforced in  accordance  with the terms  hereof from time to time against any
Lessee as often as occasion  therefor may arise and without  requirement  on the
part of Lessor or any  Certificate  Purchaser first to marshal any of its claims
or to exercise any of its rights  against any of the other Lessees or to exhaust
any remedies  available  to it against any of the other  Lessees or to resort to
any other source or means of obtaining  payment of any of the  Obligations or to
elect any other  remedy.  The  provisions  of this  Section 4.8 shall  remain in
effect  until  all the  Obligations  hereunder  shall  have been paid in full or
otherwise  fully  satisfied.  If at any time, any payment,  or any part thereof,
made in respect of any of the  Obligations,  is rescinded  or must  otherwise be
restored  or  returned  by  Lessor  or  any  Certificate   Purchasers  upon  the
insolvency,  bankruptcy  or  reorganization  of any Lessee,  or  otherwise,  the
provisions  of this Section 4.8 will  forthwith be  reinstated  and in effect as
though such payment had not been made.

     (g)  Notwithstanding  any provision to the contrary  contained herein or in
any other of the Operative  Documents,  the obligations of each Lessee hereunder
shall be limited to an aggregate  amount equal to the largest  amount that would
not render its obligations  hereunder  subject to avoidance under Section 548 of

discretion  and each Lessee shall be bound by and  obligated by all of the terms
of any such document executed by Parent Guarantor on its behalf,  (b) any notice
or  other  communication  delivered  by  Lessor  or  any  Certificate  Purchaser
hereunder  to Parent  Guarantor  shall be deemed to have been  delivered to each
Lessee and (c) Lessor and each Certificate  Purchaser shall accept (and shall be

Unit leased by such Lessee. No Lessee shall (a) use, operate,  maintain or store
any Unit or any portion  thereof in  violation  of Section 5.3 or any  Insurance
Requirement; (b) sublease, assign or otherwise permit the use of any Unit except
as may be permitted by Section 5.1(b),  Section 5.2 and Article IV of the Parent
Guaranty;  (c) except as set forth in Section 5.1(b), Section 5.2 and Article IV
of the Parent Guaranty,  sell, assign or transfer any of its rights hereunder or
in any Unit, or directly or indirectly create, incur or suffer to exist any Lien
on any of its rights  hereunder or in any Unit,  except for Permitted  Liens; or
(d) except in connection with any maintenance or repair thereof, permit any Unit
or any Part  relating to such Unit to be located at any  location  other than on
real  property  owned by such  Lessee or on which  such  Lessee has the right to
place such Unit in West  Virginia,  Virginia or Kentucky;  provided that if such
Lessee wishes to move any such Unit after the Closing  Date,  such Lessee agrees
to comply with the  provisions of Section  13.1(h) and provided  further that if
the new  location is in Virginia or Kentucky,  such Lessee  agrees to provide an
opinion of local  counsel in Virginia or  Kentucky,  as the case may be, in form
and substance satisfactory to Lessor and Certificate  Purchasers.  Lessees will,
for the benefit of the Certificate Purchasers,  defend Lessor's title to all the
Units.

     (b) So long as no Incipient Default or Event of Default shall have occurred
and be  continuing,  any Lessee  may,  upon prior  written  notice to Lessor and
compliance  with the  provisions of Section  13.1(h),  use and lease any Unit or
Units leased by any other Lessee hereunder.

     Section 5.2. Subleases and Assignments.  No Lessee shall, without the prior
written consent of Lessor and the Required Certificate  Purchasers,  sublease or
otherwise relinquish possession of any Unit, or assign, transfer or encumber its
rights,   interests  or  obligations   hereunder  and  any  attempted  sublease,
relinquishment,  assignment, transfer or encumbering by any lessee shall be null
and void,  except as provided in this  Section 5.2 or pursuant to a  transaction
permitted under clause (e) of Article IV of the Parent  Guaranty.  Each sublease
entered  into in  accordance  with this  Section  5.2 shall be  referred to as a
"Sublease".  So long as no  Incipient  Default  or Event of  Default  shall have
occurred and be continuing,  any Lessee may (i) sublease any Unit or Units to a,
direct or indirect,  wholly-owned  Subsidiary  of Parent  Guarantor  without the
prior  written  consent of Lessor or (ii)  sublease all but not less than all of
the Units leased by such Lessee to any  corporation  organized under the laws of
the United States or any State thereof with the prior written consent of Lessor,
which consent shall not be  unreasonably  withheld,  if the Sublessee is not the
subject of any case or proceeding  under any  bankruptcy,  insolvency or similar
law; provided,  that any Sublease entered into pursuant to this Section 5.2 must
satisfy each of the following conditions:

          (a) such Sublease shall (i) automatically  expire upon the termination
     of this Lease, (ii) be expressly  subordinate and subject to this Lease and
     the Liens  created  hereunder and (iii)  expressly  require the Units to be
     returned as directed by Lessor or the Required Certificate  Purchasers upon
     notice to the sublessee that an Event of Default shall have occurred and be
     continuing;

          (b) such Sublease shall be in writing and shall expressly prohibit any
     further assignment, sublease or transfer;

          (c) such Sublease shall not contain a purchase  option in favor of the
     Sublessee or any other provision pursuant to which the Sublessee may obtain
     record or beneficial title to any Unit leased thereunder from such Lessee;

          (d) such  Sublease  shall  prohibit  the  Sublessee  from  making  any
     alterations or modifications to any Unit that would violate this Lease;

          (e) such  Sublease  shall  require the Sublessee to maintain each Unit
     subleased thereunder in accordance with Section 5.3;

          (f) all of such Lessee's  rights,  title and interest in, to and under
     such Sublease shall be pledged by such Lessee to Lessor, for the benefit of
     Certificate  Purchasers,  as collateral for Lessees'  obligations under the
     Operative  Documents,  by delivery of an executed original counterpart upon
     the execution and delivery thereof,  marked as the sole original  execution
     counterpart  for Uniform  Commercial  Code  purposes,  to Lessor,  and such
     Lessee shall, at its own cost and expense,  do any further act and execute,
     acknowledge, deliver, file, register and record any further documents which
     Lessor or Certificate Purchasers may reasonably request in order to create,
     perfect,  preserve and protect Lessor's and Certificate Purchasers' Lien in
     such Sublease;

          (g) such Lessee shall not,  without  Lessor's  prior written  consent,
     permit or consent to any  renewal or  extension  of a Sublease  at any time
     when  an  Incipient  Default  or  Event  of  Default  has  occurred  and is
     continuing; and

          (h) such Lessee shall notify Lessor and each Certificate  Purchaser in
     writing not less than 30 days prior to entering  into any  Sublease,  which
     notice shall  include (i) a  description  of the Unit or Units to be leased
     thereunder,  and (ii) the street address, city, county and State where such
     Unit or Units will be located during the term of such Sublease.

     The  liability  of each Lessee  with  respect to this Lease and each of the
other  Operative  Documents  to  which it is a party  shall  not be  altered  or
affected in any way by the existence of any Sublease.

     Section 5.3. Maintenance.  At all times during the term of this Lease, each
Lessee shall, at its own cost and expense:

          (a) keep,  repair,  maintain and preserve  each of the Units leased by
     such Lessee in at least as good order and operating  condition,  repair and
     appearance as when originally  delivered,  ordinary wear and tear excepted,
     and in  conformance  with (i) such  maintenance  and repair  standards  and
     procedures  as are set forth in the  manufacturer's  manuals  pertaining to
     such Units, (ii) such standards or procedures as may be required to enforce
     warranty  claims  against each vendor and  manufacturer  of each such Unit,
     (iii) such  maintenance and repair  standards used by such Lessee or any of
     its  Affiliates for similar  equipment  owned or leased by it, and (iv) all
     Applicable  Laws and  Regulations  and Insurance  Requirements,  and in the
     event  that  Applicable  Laws  and  Regulations   require  any  alteration,
     replacement  or  addition  of or to any Part on any Unit,  such Lessee will
     conform therewith at its own expense;

          (b) (i) conduct all scheduled  maintenance of each Unit leased by such
     Lessee in conformity with such Lessee's and its Affiliates' past practices,
     and manufacturer's maintenance and repair guidelines, for similar equipment
     (including,   without   limitation,   such  Lessee's  and  its  Affiliates'
     maintenance program for such equipment) and (ii) maintain each such Unit so
     as to preserve its  remaining  economic  useful life,  utility and residual
     value;

          (c) cause each Unit  leased by such  Lessee to continue to have at all
     times the capacity and functional ability to perform, on a continuing basis
     (subject to normal  interruption  in the  ordinary  course of business  for
     maintenance,  inspection,  service,  repair and testing) and in  commercial
     operation, the functions for which it was specifically designed.

     Each  Lessee  shall  prepare  and  deliver  to Lessor  and the  Certificate
Purchasers within a reasonable time prior to the required date of filing (or, to
the extent permissible, file on behalf of Lessor and the Certificate Purchasers)
any and all reports to be filed by Lessor or any Certificate  Purchaser with any
Authority by reason of the ownership by Lessor or any  Certificate  Purchaser of
the Units or the leasing  thereof to such  Lessee.  Lessor and each  Certificate
Purchaser  agrees to inform such Lessee of any request for such reports received
by it. Each Lessee shall maintain or cause to be maintained,  all records,  logs
and other materials required by any Authority having jurisdiction over the Units
leased by such Lessee or such Lessee.  Each Lessee shall permit  Lessor and each
Certificate  Purchaser to inspect any and all records,  logs and other materials
maintained by such Lessee or any of its Affiliates in respect of each Unit. Each
Lessee hereby waives any right now or hereafter conferred by law to make repairs
on the Units at the expense of Lessor or any Certificate Purchaser.

     Section 5.4. Alterations, Modifications, etc. In case any Unit, or any item
of  equipment,  part or  appliance  therein  (each,  a "Part") is required to be
altered,  added to,  replaced or modified in order to comply with any Applicable
Laws and Regulations (a "Required  Alteration")  pursuant to Sections 5.1 or 5.3
hereof,  the Lessee of such Unit agrees to make such Required  Alteration at its
own  expense.  The  Lessee  of any  Unit  shall  have  the  right  to  make  any
modification,  alteration or improvement  to such Unit (herein  referred to as a
"Permitted  Modification"),  or to remove any Part  which has  become  worn out,
broken or  obsolete,  provided in each case that such Lessee  continues to be in
compliance  with  Sections  5.1 and 5.3 hereof and that such action (a) will not
decrease  the economic  value of the  applicable  Unit or impair its  originally
intended use or function or decrease  its economic  useful life and (b) will not
cause such Unit to become  suitable  for use only by such  Lessee or only in the
business  in  which  such  Lessee  is  engaged.   In  the  event  any  Permitted
Modification (i) is readily  removable  without impairing the value or use which
the Unit would have had at such time had such Part not been affixed or placed to
or on such Unit (a  "Removable  Part"),  (ii) is not a Required  Alteration  and
(iii) is not a Part which replaces any Part originally incorporated or installed
in or  attached  to such Unit on the date on which such Unit  became  subject to
this Lease, or any Part in replacement of or substitution  for any such original
Part (each an "Original Part"), any such Permitted Modification,  if no Event of
Default is  continuing,  shall be and remain the  property of the Lessee of such
Unit. To the extent such Permitted Modification is not a Removable Part, or is a
Required  Alteration or an Original Part, and, to the extent a Removable Part is
not the  property  of the Lessee of any Unit  because of the  continuance  of an
Event of Default, the same shall immediately and automatically be and become the
property of Lessor,  for the benefit of Certificate  Purchasers,  and subject to
the terms of this Lease.  Any Required  Alterations,  and any Parts installed or
replacements  made by any Lessee  upon any Unit  pursuant to its  obligation  to
maintain and keep the Units in good order,  operating condition and repair under
Section 5.3 (collectively, "Replacement Parts") and all other Parts which become
the property of Lessor shall be  considered,  in each case,  accessions  to such
Unit and title thereto or security  interest  therein shall be  immediately  and
automatically vested in Lessor, for the benefit of Certificate  Purchasers.  All
Replacement  Parts shall be free and clear of all Liens  (other  than  Permitted
Liens) and shall be in as good an operating condition as, and shall have a value
and utility at least equal to, the Parts replaced,  assuming such replaced Parts
and the relevant Units were  immediately  prior to such replacement or the event
or events necessitating such replacement in the condition and repair required to
be maintained  by the terms  hereof.  Any Part at any time removed from any Unit
shall remain subject to the interests of Lessor and Certificate Purchasers under
the Operative Documents,  no matter where located,  until such time as such Part
shall be  replaced  by a Part which has been  incorporated  or  installed  in or
attached to such Unit and which meets the  requirements  for a Replacement  Part
specified  above.  No later than 45 days after the end of each fiscal quarter of
any Lessee,  such Lessee shall deliver to Lessor, for the benefit of Certificate
Purchasers,  a Bill of Sale  evidencing the conveyance by such Lessee to Lessor,
for the  benefit  of  Certificate  Purchasers,  of  each  Replacement  Part  not
previously  evidenced by a Bill of Sale (provided that any Replacement Part with
a Fair Market Value of less than $250,000 need not be specifically  described in
such Bill of Sale) and such other  documents in respect of such Part or Parts as
Lessor may  reasonably  request  in order to confirm  that title to such Part or
Parts has  passed to  Lessor,  for the  benefit of  Certificate  Purchasers,  as
hereinabove provided. Any such Replacement Part, regardless of whether evidenced
by a Bill of Sale,  shall become  subject to this Lease and shall be deemed part
of such Unit, for all purposes hereof to the same extent as the Parts originally
incorporated or installed in such Unit, and title to such Replacement Part shall
thereupon vest in Lessor. All replacements pursuant to this Section 5.4 shall be
purchased by Lessees with their own funds.  There shall be no  obligation on the
part of Lessor or any Certificate  Purchaser to pay for or otherwise finance any
such replacement.

     Section 5.5.  Liens. No Lessee will directly or indirectly  create,  incur,
assume  or  suffer to exist any Lien  (other  than  Permitted  Liens) on or with
respect to (i) any Unit or any Part thereof or any other Collateral, Lessor's or
any Certificate  Purchaser's title thereto, or any interest therein or (ii) this
Lease or any of Lessor's or any  Certificate  Purchaser's  interests  hereunder.
Each Lessee,  at its own expense,  will promptly pay, satisfy and otherwise take
such actions as may be necessary to keep this Lease and the Units free and clear
of, and to duly  discharge  or  eliminate  or bond in a manner  satisfactory  to
Lessor,  any such Lien not  excepted  above if the same shall arise at any time.
Each Lessee will notify Lessor or each  Certificate  Purchaser and each assignee
in writing promptly upon becoming aware of any Tax or other Lien (other than any
Lien  excepted  above) that shall attach to the Units or any Unit leased by such
Lessee, and of the full particulars thereof.  Without limiting the foregoing, no
Lessee shall assign or pledge any of its rights under any Sublease to any Person
other than Lessor, for the benefit of Certificate Purchasers.

     Section 5.6. Identifying Numbers;  Legend; Changes;  Inspection.  Within 60
days after the  Delivery  Date,  each Lessee will cause each Unit leased by such
Lessee to be kept numbered with the identification  number as shall be set forth
on Schedule  II, and each Lessee will at all times keep and  maintain,  plainly,
distinctly,  permanently  and  conspicuously  marked  on each  side of each Unit
leased by such Lessee that is a Major Unit, in letters not less than one inch in
height,  the words  "subject to a security  interest in favor of First  Security
Bank, National Association,  as Trustee for others under a Trust Agreement and a
Lease  Intended  as  Security  each  dated  as of  January  15,  1998"  or other
appropriate words designated by Lessor or the Required  Certificate  Purchasers,
with appropriate  changes thereof and additions thereto as from time to time may
be required by law in order to protect Lessor's right,  title and interest,  for
the  benefit of the  Certificate  Purchasers,  in such Unit.  Each  Lessee  will
replace  promptly  any such words on any Unit leased by such Lessee which may be
removed,   defaced,   obliterated  or  destroyed.  No  Lessee  will  change  the
identification number of any Unit unless and until (i) a statement of new number
or numbers to be  substituted  therefor  shall have been delivered to Lessor and
the Certificate  Purchasers and filed,  recorded and deposited by such Lessee in
all public  offices  where  this  Lease  shall  have been  filed,  recorded  and
deposited or any financing  statement has been filed in respect thereof and (ii)
such  Lessee  shall have  furnished  Lessor and the  Certificate  Purchasers  an
opinion of counsel in form and substance  reasonably  satisfactory  to Lessor to
the effect that such statement has been so filed,  recorded and deposited,  such
filing,  recordation  and deposit will protect the right,  title and interest of
Lessor, on behalf of the Certificate  Purchasers in such Units and that no other
filing,  recording,  deposit or giving of notice  with or to any other  Federal,
state or local  government or agency thereof is necessary to protect such right,
title and  interest.  The Units  leased by any Lessee may be  lettered  with the
names or  initials  or other  insignia  customarily  used by such  Lessee or its
permitted sublessees but such Lessee will not allow the name of any other Person
to be placed on any Unit as designation  that might be interpreted as a claim of
ownership.  Upon the request of Lessor or the Required  Certificate  Purchasers,
each Lessee  shall make the Units  leased by such Lessee  available to Lessor or
any  Certificate  Purchaser,  its agents,  or its  Assignees  for  inspection at
reasonable  times and at  reasonable  locations and upon  reasonable  notice and
shall also make such  Lessee's  records  pertaining  to the Units  available for
inspection,  provided that from and after the occurrence of an Event of Default,
all costs and expenses of Lessor or any Certificate Purchaser in connection with
such inspection shall be borne, jointly and severally, by Lessees.


                                   Article VI

                             Risk of Loss; Insurance

     Section 6.1. Casualty. Upon the occurrence of a Casualty prior to or during
the term of this Lease,  the Lessee of the Unit or Units suffering such Casualty
or Lessee's  Agent shall give  Certificate  Purchasers  and Lessor prompt notice
thereof (a "Casualty Notice"). The Casualty Notice shall specify whether:

          (a) Lessees will, on a joint and several basis, pay to Lessor, for the
     benefit of the  Certificate  Purchasers,  the  Casualty  Amount of the Unit
     suffering such Casualty, which payment shall be made no later than the next
     scheduled  Payment Date occurring  after such Casualty or, if such Casualty
     occurs  during the last 5 Business  Days prior to a Payment  Date,  then no
     later  than the  second  Payment  Date (the  "Casualty  Settlement  Date"),
     provided that in any event the Casualty  Settlement  Date shall be no later
     than the last day of the Lease Term; or

          (b) such  Lessee  will  replace  the Unit  with  respect  to which the
     Casualty has occurred pursuant to the following  provisions of this Section
     6.1,  provided that upon the  occurrence  and during the  continuance of an
     Event of Default or an  Incipient  Default,  Lessees  shall be jointly  and
     severally obligated, at the option of Lessor, to make the payments referred
     to in clause (a) above and shall not be entitled  to exercise  any right or
     election of replacement pursuant to this clause (b).

     If such Lessee has  elected,  or is required,  to pay the  Casualty  Amount
pursuant  to clause (a) above,  Lessees,  on a joint and  several  basis,  shall
continue to make all  payments of Rent due under this Lease until and  including
the Casualty  Settlement Date. Upon payment of the Casualty Amount in respect of
any Unit  suffering a Casualty on such Casualty  Settlement  Date, the remaining
scheduled  payments of Capital  Rent, if any, as well as the amount of the Lease
Balance remaining following the payment of the final installment of Capital Rent
at the end of the Lease Term  (assuming  the  exercise of all  possible  Renewal
Terms) shall each be reduced by an amount equal to the product of the  scheduled
amount of such Capital Rent payment or such remaining Lease Balance, as the case
may be (determined  in each case prior to the receipt of such Casualty  Amount),
multiplied by the Unit Value Fraction of the Unit suffering such Casualty.

     If such Lessee or Lessees'  Agent has given notice that such Lessee intends
to replace the Unit suffering such Casualty,  and such  replacement is permitted
under the foregoing  clause (b), such Lessee may make subject to this Lease, not
more than 60 days after the date of such Casualty Notice, a replacement for such
Unit meeting the suitability  standards hereinafter set forth. To be suitable as
a  replacement  Unit,  an  item  must  be of the  same  general  type,  year  of
construction  (or a later year of  construction),  function,  utility,  state of
repair and operating condition (immediately preceding the Casualty assuming that
such Unit had been  maintained in  accordance  with the terms of Section 5.3) as
the Unit suffering the Casualty,  must have a Fair Market Value of not less than
the Fair Market Value  (immediately  preceding  the Casualty  assuming that such
Unit had been  maintained  in  accordance  with the terms of Section 5.3) of the
Unit  suffering  the  Casualty  and be free and  clear of any Liens  other  than
Permitted  Liens.  Such  Lessee  shall  cause  a Bill  of  Sale  and  Acceptance
Certificate  to  be  executed  and  delivered  to  Lessor  and  the  Certificate
Purchasers  in order to subject such  replacement  item to this Lease,  and upon
such  execution  and  delivery  and the  receipt by Lessor  and the  Certificate
Purchasers of (i) evidence  reasonably  satisfactory  to Lessor of such Lessee's
compliance  with the  insurance  provisions  of Section 6.2 with respect to such
replacement  item,  and (ii) an opinion  of  counsel to such  Lessee in form and
substance reasonably  satisfactory to Lessor opining, among other things, to the
effect that all appropriate  filings,  recordings and other acts have been taken
to protect the right, title and interest of Lessor, on behalf of the Certificate
Purchasers,  in such  replacement  item  and that no  other  filing,  recording,
deposit,  or giving of notice with or to any  Authority  is necessary to protect
such right,  title and interest in such replacement  item, such replacement item
shall be deemed a "Unit" for all purposes hereof.

     If Lessor has received the amount  payable with respect to the Casualty and
all other  amounts due  hereunder  and no Event of Default or Incipient  Default
exists,  the  applicable  Lessee  shall be entitled  to receive  from Lessor the
proceeds of any  recovery  in respect of the Unit from  insurance  or  otherwise
("Casualty  Recoveries"),  and  Lessor,  subject  to the  rights of any  insurer
insuring the Units as provided herein, shall execute and deliver to such Lessee,
or to its assignee or nominee, a quitclaim bill of sale (without representations
or  warranties  except that the Unit is free and clear of Lessor  Liens) for the
Unit,  and such other  documents as may be required to release the Unit from the
terms of this Lease, in such form as may reasonably be requested by such Lessee.
All fees,  costs and expenses  relating to a  substitution  as described  herein
shall be borne by Lessees.  Except as  otherwise  provided in this  Section 6.1,
Lessees shall not be released from their obligations  hereunder in the event of,
and shall bear the risk of, any Casualty to any Unit prior to or during the term
of this Lease and thereafter until all Lessees' obligations  hereunder are fully
performed.

     All Casualty Recoveries (or other payments (including,  without limitation,
insurance  proceeds)  received  at any time by  Lessor  or any  Lessee  from any
Authority or other party with respect to any loss or damage to any Unit or Units
not  constituting  a  Casualty)  (collectively,  "Casualty  Proceeds")  shall be
deposited  into a deposit  account  established by Lessor for the benefit of the
Certificate  Purchasers (the "Deposit  Account").  Any Casualty  Proceeds in the
Deposit Account shall be remitted  promptly to the Lessee of the damaged Unit or
Units after either (i) with respect to a Casualty,  Lessees' compliance with the
requirements of clause (a) or clause (b), as applicable,  of this Section 6.1 or
(ii) with respect to any other loss or damage,  Lessees'  full  compliance  with
Section 5.3.

     Lessees hereby assume all risk of loss, damage, theft, taking, destruction,
confiscation,   requisition,   commandeering,   taking  by  eminent   domain  or
condemnation,  partial  or  complete,  of or to each  Unit,  however  caused  or
occasioned,  such risk to be borne by Lessees with respect to each Unit from the
date of this Lease,  and continuing  until such Unit has been returned to Lessor
in  accordance  with the  provisions  of  Article  XVI.  Lessees  agree  that no
occurrence  specified in the preceding  sentence  shall  impair,  in whole or in
part, any obligation of Lessees under this Lease, including, without limitation,
the obligation to pay Rent.

     Section 6.2.  Insurance  Coverages.  Each Lessee shall at all times, at its
expense, cause to be carried and maintained with financially sound and reputable
insurers,  insurance  against loss or damage to the Units leased by such Lessee,
of the kinds and in the amounts customarily  maintained by prudent  corporations
in similar  circumstances  carrying on similar businesses,  provided that in any
event each Lessee will maintain:

          (a) Property  Insurance -- insurance against risks of physical loss or
     damage with respect to the Units (including, without limitation, earthquake
     insurance) with deductibles  customarily maintained by prudent corporations
     in similar circumstances carrying on similar businesses and in such minimum
     amounts as are consistent with industry standards;  provided, however, that
     at no time  shall the  amount of  coverage  be less than the sum of (x) the
     outstanding  Lease Balance and (y) an amount equal to the aggregate  amount
     of Accrual Rent to be accrued  under this Lease for 90 days  following  the
     date of determination;

          (b) Public  Liability  Insurance -- combined  single  limit  insurance
     against  claims for bodily injury,  death or property  damage in amounts at
     least equal to $35,000,000 single limit per occurrence and with deductibles
     not to exceed $1,000,000 per occurrence; and

          (c) Other Insurance -- such other insurance,  including  comprehensive
     motor vehicle,  worker's compensation and business interruption  insurance,
     in each case of the kinds and, in such  amounts  and against  such risks as
     are customarily maintained by prudent corporations in similar circumstances
     carrying  on  similar  businesses,  including,  with  respect  to  worker's
     compensation insurance, self-insurance to the extent customarily maintained
     by  prudent  corporations  in  similar  circumstances  carrying  on similar
     businesses.

     Such insurance shall be written by reputable  insurance  companies that are
financially sound and solvent,  rated in Best's Insurance Guide or any successor
thereto  (or if  there be  none,  an  organization  having  a  similar  national
reputation) with a general  policyholder rating of "A" and a financial rating of
at least "X" or otherwise  acceptable to Lessor.  All such insurance  shall name
Lessor and the Certificate  Purchasers as additional insureds or as loss-payees,
as their respective interests may appear, and, as sole loss payees to the extent
such claims relate to the Units subject to this Lease.  Each policy  referred to
in this  Section  6.2 shall  provide  that (i) it will not be  cancelled  or its
limits  reduced,  or allowed to lapse without renewal or changed in any material
manner,  except  after not less than 30 days'  written  notice to Lessor and the
Certificate  Purchasers;  (ii)  the  interests  of  Lessor  and the  Certificate
Purchasers  shall not be  invalidated  by any act or negligence of, or breach of
representation  or warranty  by, any Lessee or any Person  having an interest in
any Unit;  (iii) such  insurance is primary with respect to any other  insurance
carried by or available to Lessor  and/or any  Certificate  Purchaser;  (iv) the
insurer shall waive any right of  subrogation,  setoff,  counterclaim,  or other
deduction,   whether  by  attachment  or  otherwise,   against  Lessor  and  the
Certificate  Purchasers;  (v) the  insurer  shall  waive  any right to claim any
premiums or commission  against Lessor or any  Certificate  Purchaser;  and (vi)
such policy shall  contain a  cross-liability  clause  providing for coverage of
Lessor and each Certificate Purchaser as if separate policies had been issued to
each of them.  Lessees or  Lessees'  Agent will  notify  Lessor and  Certificate
Purchasers promptly of any policy  cancellation,  reduction in policy limits, or
of any  modification  or  amendment  which  could  adversely  affect  Lessor  or
Certificate Purchasers.

     Section 6.3.  Insurance  Certificates.  Prior to the initial Delivery Date,
and  thereafter  not  less  than 15 days  prior to the  expiration  dates of the
expiring policies  theretofore  delivered pursuant to Section 6.2, Lessees shall
deliver  to Lessor and the  Certificate  Purchasers  certificates  issued by the
insurer(s)  for the  insurance  maintained  pursuant to Section  6.2;  provided,
however,  that if the delivery of any certificate is delayed,  Lessees shall not
be deemed to be in violation of the obligation to deliver such  certificate  if,
within  such 15 day period,  Lessees  deliver an  executed  binder with  respect
thereto and thereafter  delivers the certificate upon receipt thereof.  Upon the
request of Lessor or the Required Certificate  Purchasers,  Lessees will furnish
to  Lessor  and the  Certificate  Purchasers  a  certificate  of an  independent
insurance  broker of  recognized  standing  evidencing  the  maintenance  of all
insurance required hereunder.


                                   Article VII

     Section 7.4) from and against,

any and all Claims of every kind and nature  whatsoever  that may be imposed on,
incurred  by, or asserted  against any  Indemnitee,  which are not  directly and

(provided  that the  indemnification  provided  under  this  Section  7.1  shall
specifically  include  matters  based on or arising from the  negligence  of any
Indemnitee),  whether or not such Indemnitee shall also be indemnified as to any
such Claim by any other  Person and whether or not such Claim  arises or accrues
prior to the Delivery Date or after the  Termination  Date, and which relates in
any way to or arises in any way out of:

          (a)  any  of the  Operative  Documents  or  any  of  the  transactions
     contemplated  thereby,  or any  investigation,  litigation or proceeding in

     pay  over  any  amount  as a  result  of any  Lien)  on  any of the  Units,
     including,  without  limitation,  (i) Claims or penalties  arising from any

     without limitation,  investigation  costs,  cleanup costs,  response costs,

          (d) the  sale or other  disposition  of any of the  Units,  including,

     Option or as a result of the exercise of remedies;

          (e) the offer, issuance, sale or delivery of the Certificates;

          (f) the breach or alleged  breach by any Lessee,  Parent  Guarantor or
     any Subsidiary  Guarantor of any  representation  or warranty made by it or
     deemed made by it in any Operative Document;

          (g) the  transactions  contemplated  hereby or by any other  Operative
     Document  in respect of the  application  of Parts 4 and 5 of Subtitle B of
     Title I of  ERISA  and any  prohibited  transaction  described  in  Section
     4975(c) of the Code;

          (h) any Claims  related to the Release from any Unit of any  substance

     the use of any Unit for the  transportation  or  storage  of any  Hazardous
     Material;

          (i) any failure on the part of any  Lessee,  Parent  Guarantor  or any

          (j) any other  agreement  entered  into or  assumed  by any  Lessee in
     connection with any Unit.

     It is expressly understood and agreed that this Section 7.1 shall not apply
to Claims in respect of:

          (A) Taxes (such  Claims  being  subject to Section  7.2),  except with
     respect to (1) taxes or  penalties  included in Claims  described in clause
     (g)  above,  and (2) any  payment  necessary  to make  payments  under this
     Section 7.1 in accordance with Section 7.4;

          (B)  as to an  Indemnitee,  Lessor  Liens  which  such  Indemnitee  is
     responsible for discharging under the Operative Documents; and

          (C) the gross  negligence or willful  misconduct of such Indemnitee or
     any Affiliate, agents, officers directors, servants or employees thereof.

     Section  7.2.  General  Tax  Indemnity.  (a)  Lessees  shall,  jointly  and
severally,  pay,  defend and indemnify and hold each  Indemnitee  harmless on an
after-tax  basis (in  accordance  with  Section  7.4) from any and all  Federal,
state,  local and foreign  Taxes  imposed on or with respect to or in connection
with any Indemnitee,  the Units or any portion thereof,  any Operative Document,
any Lessee or any  sublessee  or user of any Unit,  howsoever  imposed,  whether
levied or imposed upon or asserted against any Indemnitee, any Unit, or any Part
thereof,  by any  taxing  Authority  (including  any  Federal,  state  or  local
government or taxing  Authority in the United States and any taxing Authority or
governmental subdivision of a foreign country), upon or with respect to:

          (i) the acquisition, mortgaging, design, manufacture,  re-manufacture,
     construction,     preparation,    installation,    inspection,    delivery,
     non-delivery,   acceptance,  rejection,  purchase,  ownership,  possession,
     rental, lease, sublease,  repossession,  maintenance,  repair,  alteration,
     modification,  addition or  substitution,  storage,  titling or  retitling,
     transfer  of  title,  registration  or  re-registration,  redelivery,  use,
     operation,  condition,  financing,   refinancing,  sale,  return  or  other
     application  or disposition of the Units or any Unit or Part thereof or the
     imposition  of any Lien (or  incurrence  of any  liability to refund or pay
     over any amount as a result of any Lien) thereon,

          (ii) Basic  Rent or  Supplemental  Rent or the  receipts  or  earnings
     arising from or received  with respect to the Units or any Unit or any Part
     thereof,  or any  interest  therein  or any  applications  or  dispositions
     thereof,

          (iii) any other  amount paid or payable  pursuant  to this Lease,  the
     Certificates or any other Operative Documents,

          (iv)  the  Units  or any  Unit or any  Part  thereof  or any  interest
     therein,

          (v)  all or  any  of the  Operative  Documents,  any  other  documents
     contemplated thereby and any amendments and supplements thereto, and

          (vi) otherwise with respect to or in connection with the  transactions
     contemplated by the Operative Documents;

provided,  however,  that the indemnification  obligation of this Section 7.2(a)
shall  not  apply  to  (1)  Taxes  which  are  based  upon  or  measured  by the
Indemnitee's  net income or which are expressly in substitution  for, or relieve
Indemnitee  from,  any actual Tax based upon or  measured  by  Indemnitee's  net
income  (other than any such Taxes imposed by means of  withholding);  (2) Taxes
characterized under local law as franchise,  net worth, or shareholder's capital
(excluding,  however, any value-added,  license, property or similar Taxes); and
(3) if no Event of Default  exists,  Taxes  based upon the  voluntary  transfer,
assignment or disposition by Lessor or any Certificate Purchaser of any interest
in any of the Units (other than  transfers  pursuant to the exercise of the Sale
Option or the Purchase Option,  or any other transfer to any Lessee or otherwise
pursuant to this Lease).  Notwithstanding  the proviso of the preceding sentence
of this Section 7.2(a), Lessees shall, jointly and severally,  pay or reimburse,
and indemnify and hold harmless,

          (A) any  Indemnitee  against  any Tax based on, or measured by the net
     income of, such  Indemnitee  imposed by any Federal,  state or local taxing
     Authority  in the  United  States  (or any  taxing  Authority  in any other
     jurisdiction  in which such  Indemnitee  maintains its  principal  place of
     business)  to the  extent  such Tax would not have been  imposed  if on the
     Delivery Date the  Certificate  Purchasers  had advanced  funds directly to
     Lessees in the form of a loan  secured  by the Units in an amount  equal to
     the aggregate  amount funded by the Certificate  Purchasers on the Delivery
     Date, with the debt service for such loan equal to the rents provided under
     this Lease and a principal balance due at the end of such term in an amount
     equal to the Lease Balance remaining at the end of the Lease Term, or

          (B) any  Indemnitee  which is not  incorporated  under the laws of the
     United  States  or a state  thereof  and which has  complied  with  Section
     7.2(c),  from any deduction or  withholding  of any United  States  Federal
     income tax.

     All of the indemnities contained in this Section 7.2 shall continue in full
force and effect  notwithstanding  the expiration or earlier termination of this
Lease in whole or in part,  including the termination of this Lease with respect
to any Unit or all of the Units,  and are expressly made for the benefit of, and
shall be enforceable by, each Indemnitee.

     (b)  Lessees  or  Lessees'  Agent  will  promptly   notify  Lessor  or  the
Certificate  Purchasers  of all  reports  or  returns  required  to be made with
respect to any Tax with  respect to which  Lessees  are  required  to  indemnify
hereunder,  and will, if permitted by Applicable Laws and Regulations,  file the
same.  If Lessees are not  permitted  to so file,  Lessees  shall  prepare  such
reports  or  returns  for  signature  by  Lessor or the  applicable  Certificate
Purchaser and shall forward the same, together with immediately  available funds
for payment of any Tax due, to Lessor or such  Certificate  Purchaser,  at least
ten (10) days in advance of the date such  payment is to be made.  Upon  written
request,  Lessees shall furnish Lessor or any Certificate  Purchaser with copies
of all paid receipts or other appropriate evidence of payment for all Taxes paid
by Lessees pursuant to this Section 7.2.

     (c) At least  five (5)  Business  Days prior to the first date on which any
payment is due under this Lease for the account of any Certificate Purchaser not
incorporated  under  the laws of the  United  States  or a state  thereof,  such
Certificate  Purchaser  agrees that it will have delivered to Lessees' Agent and
Lessor two duly completed  copies of United States Internal Revenue Service Form
1001 or 4224,  certifying  in either  case that such  Certificate  Purchaser  is
entitled to receive payments under the Operative  Documents without deduction or
withholding of any United States Federal income taxes,  or at a reduced rate, if
applicable.  Each  Certificate  Purchaser  which so delivers a Form 1001 or 4224
further undertakes to deliver to Lessees' Agent and Lessor two additional copies
of such form (or a successor  form) on or before the date that such form expires
(currently,  three successive calendar years for Form 1001 and one calendar year
for  Form  4224) or  becomes  obsolete  or after  the  occurrence  of any  event
requiring  a  change  in the most  recent  forms so  delivered  by it,  and such
amendments  thereto or  extensions  or  renewals  thereof  as may be  reasonably
requested  by  Lessees'  Agent or  Lessor,  in each  case  certifying  that such
Certificate  Purchaser  is  entitled  to receive  payments  under the  Operative
Documents  without  deduction or withholding of any United States Federal income
taxes,  unless an event (including any change in treaty,  law or regulation) has
occurred  prior to the  date on  which  any such  delivery  would  otherwise  be
required which renders all such forms  inapplicable  or which would prevent such
Certificate  Purchaser  from duly  completing  and delivering any such form with
respect to it and such Certificate  Purchaser  advises Lessees' Agent and Lessor
that it is not capable of receiving  payments  without any withholding of United
States Federal income tax.

     Section 7.3.  Excessive Use Indemnity.  In the event that at the end of the
Lease Term: (a) Lessees elects the Sale Option;  and (b) after paying to Lessor,
for the benefit of the  Certificate  Purchasers,  any amounts due under  Section
11.1(c), Proceeds and the Sale Recourse Amount, the Lease Balance shall not have
been  reduced to zero,  then  Lessees  shall  promptly  pay over to  Certificate
Purchasers  the shortfall  unless  Lessees  deliver a report from an independent
appraiser in form and substance  satisfactory to Lessor which  establishes  that
the decline in value in the Units from the aggregate amount anticipated for such
date in the  Appraiser's  report  delivered  with  respect  to each  Unit on the
Delivery Date was not due to the excessive use of any Unit,  failure to maintain
any Unit,  modifications  or alteration  which reduce the value of any Unit, any
adverse  change  in the  environmental  condition  of any  Unit,  any  defect or
exception to title of any Unit or any other cause or condition  within the power
of Lessees to control or affect, differing from ordinary wear and tear.

     Section  7.4.  Gross  Up.  If an  Indemnitee  shall  not be  entitled  to a
corresponding  and equal  deduction  with  respect  to any  payment or Tax which
Lessees  are  required to pay or  reimburse  under any other  provision  of this
Article  VII (each such  payment or  reimbursement  under this  Article  VII, an
"original  payment")  and  which  original  payment  constitutes  income to such
Indemnitee,  then Lessees  shall pay to such  Indemnitee  on a joint and several
basis on demand the  amount of such  original  payment on a gross-up  basis such
that,  after  subtracting  all Taxes imposed on such  Indemnitee with respect to
such original  payment by Lessees  (including any Taxes otherwise  excluded from
the  indemnification  provided  under  Section 7.2 and assuming for this purpose
that such  Indemnitee was subject to taxation at the highest  Federal,  state or
local  marginal  rates  applicable to widely held  corporations  for the year in
which such income is  taxable),  such  payments  shall be equal to the  original
payment to be received  (net of any  credits,  deductions  or other tax benefits
then actually  recognized  that arise from the payment by such Indemnitee of any
amount, including taxes, for which the payment to be received is made).

     Section  7.5.   Increased   Capital  Costs.   If  any  change  in,  or  the
introduction,  adoption,  effectiveness,  interpretation,   reinterpretation  or
phase-in of, any law or regulation,  directive,  guideline,  decision or request
(whether or not having the force of law) of any court, central bank regulator or
other Authority  ("Change in Law") affects or would affect the amount of capital
required or expected to be maintained by any Certificate  Purchaser  directly or
by its parent company (including,  without limitation,  any reserve requirements
specified under  regulations  issued from time to time by the Board of Governors
of the  Federal  Reserve  System and then  applicable  to assets or  liabilities
consisting of and including "Eurocurrency  Liabilities" as defined in Regulation
D of such Board of Governors) and such Certificate  Purchaser determines (in its
sole and  absolute  discretion)  that the rate of return  on it or its  parent's
capital as a  consequence  of any  Funding  made by such  Certificate  Purchaser
hereunder  to pay its share of the  Purchase  Price is reduced to a level  below
that which such Certificate  Purchaser or its parent could have achieved but for
the occurrence of any such  circumstances,  then, in any such case, upon written
notification from time to time by such Certificate  Purchaser to Lessees' Agent,
Lessees shall,  within five (5) Business Days following receipt of the statement
referred to in the next  sentence,  pay on a joint and several basis directly to
such Certificate Purchaser,  as Supplemental Rent, additional amounts sufficient
to compensate  Certificate Purchaser or its parent for such reduction in rate of
return  (subject to Section 7.4). A statement of a  Certificate  Purchaser as to
any such  additional  amount  or  amounts  (including  calculations  thereof  in
reasonable  detail) shall,  in the absence of manifest  error, be conclusive and
binding on Lessees. In determining such amount, each Certificate Purchaser shall
use  any  method  of  averaging  or  attribution  that  it  (in  its  reasonable
discretion) shall deem applicable.

     Section  7.6.  LIBO Rate  Illegal,  Unavailable  or  Impracticable.  If any
Certificate  Purchaser shall determine in good faith (which determination shall,
upon notice  thereof to Lessees'  Agent,  be conclusive  and binding on Lessees)
that

          (a) a change in law makes it  unlawful,  or the central  bank or other
     Authority  asserts that it is unlawful,  for such Certificate  Purchaser to
     make,  continue  or  maintain  any amount of such  Certificate  Purchaser's
     investment hereunder on a LIBO Rate basis,

          (b)  deposits in Dollars  (in the  applicable  amounts)  are not being
     offered  to such  Certificate  Purchaser  in the  relevant  market  for the
     applicable Rent Period,  or that by reason of  circumstances  affecting the
     interbank  eurodollar market adequate and reasonable means do not exist for
     ascertaining the applicable LIBO Rate, or

          (c) the LIBO Rate, as determined by Lessor,  will not  adequately  and
     fairly  reflect the cost to such  Certificate  Purchaser of  maintaining or
     funding its investments for the applicable Rent Period,  or that the making
     or funding of such Certificate  Purchaser's  investment hereunder on a LIBO
     Rate basis has become impracticable as a result of an event occurring after
     the date of this Lease which in the opinion of such  Certificate  Purchaser
     materially changes such investment,

then the obligations of such Certificate Purchaser to make, continue or maintain
any such investment shall, upon such determination, forthwith be suspended until
such Certificate  Purchaser shall notify Lessees' Agent that such  circumstances
no longer exist,  and all Accrual Rent allocable to such  Certificate  Purchaser
shall  automatically  be determined  on a Base Rate basis  beginning on the next
immediately  succeeding Payment Date with respect thereto or sooner, if required
by such law, assertion or determination.

     Section 7.7.  Funding Losses.  Lessees agree, on a joint and several basis,
to  reimburse  any  Certificate  Purchaser  for  any  loss or  expense  incurred
(including  any  loss or  expense  incurred  by  reason  of the  liquidation  or
reemployment of deposits or other funds acquired by such  Certificate  Purchaser
to make, continue or maintain any portion of its investment  hereunder on a LIBO
Rate basis) as a result of (i) the failure of the  transaction  contemplated  by
Article II to occur on or before the  Delivery  Date  specified  in the Delivery
Date Notice or (ii) any  payment of all or any portion of the Lease  Balance for
any reason on a date  other than a Payment  Date.  Certificate  Purchaser  shall
promptly  notify Lessees' Agent in writing of the amount of any claim under this
Section 7.7, the reason or reasons  therefor and the additional  amount required
fully to compensate such  Certificate  Purchaser for such loss or expense.  Such
written notice (which shall include calculations in reasonable detail) shall, in
the absence of manifest error, be conclusive and binding on Lessees.

     Section 7.8. Actions of Affected Certificate  Purchasers.  Each Certificate
Purchaser shall use reasonable efforts  (including  reasonable efforts to change
the booking office for this  transaction) to avoid or minimize any amounts which
might otherwise be payable pursuant to Section 7.5; provided, however, that such
efforts  shall  not be  deemed  by  such  Certificate  Purchaser,  in  its  sole
discretion,  to be  disadvantageous  to it.  In the event  that such  reasonable
efforts are insufficient to avoid or minimize such amounts that might be payable
pursuant  to  Section  7.5,  then  such  Certificate  Purchaser  (the  "Affected
Certificate  Purchaser")  shall use its  reasonable  efforts to  transfer to any
other Certificate Purchaser approved by Lessees' Agent (which itself is not then
an  Affected  Certificate  Purchaser)  its  rights  and  obligations  hereunder;
provided,  however,  that such  transfer  shall  not be deemed by such  Affected
Certificate  Purchaser,  in its sole  discretion,  to be  disadvantageous  to it
(other than the economic disadvantage of ceasing to be a Certificate Purchaser).
In the event that the Affected Certificate  Purchaser is unable, or otherwise is
unwilling,  so to  transfer  its  rights  and  obligations,  Lessees'  Agent may
designate  an  alternate   financial   institution   to  purchase  the  Affected
Certificate  Purchaser's rights and obligations hereunder,  at the amount of the
portion of the then  outstanding  Lease  Balance  allocable to such  Certificate
Purchaser  plus  accrued  Accrual  Rent on such  portion  of the Lease  Balance,
indemnities,  and other amounts owing to such Certificate Purchaser and, subject
to the  provisions  of Section 7.7 and Article  XIV,  the  Affected  Certificate
Purchaser shall transfer its rights and obligations to such alternate  financial
institution and such alternate financial  institution shall become a Certificate
Purchaser hereunder.

     Guaranty;

          (e) Any Lessee,  Parent  Guarantor or any Subsidiary  Guarantor  shall

     under  any  other  Operative  Document  (and not  constituting  an Event of
     Default under any other clause of this Section 8.1), and such default shall
     continue  unremedied  for a period of 30 days after the earlier to occur of
     (i)  written  notice  thereof  by Lessor or any  Certificate  Purchaser  to
     Lessees' Agent, Parent Guarantor or such Subsidiary Guarantor,  as the case
     may be, or (ii) a  Responsible  Officer  of any Lessee or  Lessee's  Agent,
     Parent  Guarantor  or such  Subsidiary  Guarantor,  as the case may be, has
     knowledge thereof;

          (f) (i) Any Lessee,  Parent Guarantor or any of its Subsidiaries shall

     receiver,  agent,  custodian,  liquidator or similar Person for itself or a

     involuntary  petition  filed  against it in any  bankruptcy,  insolvency or
     similar case or proceeding, or shall be adjudicated bankrupt, or shall make

     of such Lessee, Parent Guarantor or such Subsidiary, or any writ, judgment,
     warrant of  attachment,  execution  or similar  process  shall be issued or
     levied  against a substantial  part of the property,  assets or business of
     such Lessee,  Parent Guarantor or such Subsidiary,  and such proceedings or
     petition shall not be dismissed or stayed, or such writ, judgment,  warrant
     of attachment,  execution or similar process shall not be released, vacated
     or fully bonded, within 60 days after commencement,  filing or levy, as the
     case may be;

          (h) there shall have occurred any event of default in the  performance
     or observance of any  obligation or condition with respect to any amount or
     amounts of  Indebtedness  or other amounts under a synthetic lease owing by
     or guaranteed by any Lessee,  Parent  Guarantor or any of its  Subsidiaries
     the effect of which is to cause or permit the  acceleration of the maturity
     of  Indebtedness  having  a  principal  amount  or  other  amounts  under a
     synthetic lease in excess of $10,000,000 (individually or in the aggregate)
     prior to its expressed or stated  maturity or to permit the  beneficiary of
     any such  guarantee  of  indebtedness  having a  principal  amount or other
     amounts under a synthetic lease in excess of $10,000,000  (individually  or
     in the aggregate) to make a demand for payment or performance thereunder;

          (i) any of the  following  occurs:  (A) any  Reportable  Event,  which
     Lessor determines in good faith constitutes  grounds for the termination of
     any Plan by the PBGC or the  appointment  of a  trustee  to  administer  or
     liquidate any Plan, shall have occurred and be continuing;  (B) proceedings
     shall have been  instituted or other action taken to terminate any Plan, or
     a termination  notice shall have been filed with respect to any Plan; (C) a
     trustee shall be appointed to  administer  or liquidate  any Plan;  (D) the
     PBGC shall give notice of its intent to institute  proceedings to terminate
     any Plan or Plans or to appoint a trustee to  administer  or liquidate  any
     Plan;  and, in the case of the  occurrence  of (A),  (B), (C) or (D) above,
     Lessor  determines  in good  faith  that the  amount of Parent  Guarantor's
     liability is likely to exceed 10% of its  Consolidated  Tangible Net Worth;
     (E) Parent  Guarantor or any of its ERISA Affiliates shall fail to make any
     contributions  when  due to a Plan  or a  Multiemployer  Plan;  (F)  Parent
     Guarantor or any of its ERISA Affiliates shall make any amendment to a Plan
     with respect to which security is required under Section 307 of ERISA;  (G)
     Parent Guarantor or any of its ERISA  Affiliates shall withdraw  completely
     or partially from a Multiemployer  Plan; (H) Parent Guarantor or any of its
     ERISA  Affiliates  shall withdraw (or shall be deemed under Section 4062(e)
     of ERISA to withdraw) from a Multiple  Employer Plan; or (I) any applicable
     laws are adopted,  changed or  interpreted by any Authority with respect to
     or otherwise  affecting one or more Plans,  Multiemployer  Plans or Benefit
     Arrangements  and, with respect to any of the events specified in (E), (F),
     (G), (H) or (I),  Lessor  determines in good faith that any such occurrence
     would be  reasonably  likely to materially  and adversely  affect the total
     enterprise represented by Parent Guarantor and its ERISA Affiliates;

          (j) any Operative  Document or the Lien granted under this Lease shall
     (except in  accordance  with its  terms),  in whole or in part,  terminate,
     cease to be  effective  or  cease  to be the  legally  valid,  binding  and
     enforceable  obligation of any Lessee,  Parent  Guarantor or any Subsidiary
     Guarantor,  as the  case  may be,  or any  Lessee,  Parent  Guarantor,  any
     Subsidiary  Guarantor  or  any  of  their  Affiliates  shall,  directly  or
     indirectly,  contest  in any manner the  effectiveness,  validity,  binding
     nature or enforceability thereof; or the Lien securing Lessees' obligations
     under the Operative  Documents  shall,  in whole or in part,  cease to be a
     perfected first priority security interest;

          (k) a final  judgment or final  judgments for the payment of money are
     entered by a court or courts of competent  jurisdiction against any Lessee,
     Parent  Guarantor or any of its Subsidiaries and such judgment or judgments
     remain  undischarged,  unbonded  or  unstayed  for a period  (during  which
     execution shall not be effectively stayed) of 30 days;  provided,  that the
     aggregate of all such judgments exceeds $10,000,000; or

          (l) any Event of Default (as defined in the Revolving Credit Facility)
     shall have occurred under the Revolving Credit Facility.

     Section 8.2.  Remedies.  If any Event of Default exists,  Lessor shall have
the rights, options and remedies of a secured party under the UCC (regardless of
whether the UCC or a law  similar  thereto  has been  enacted in a  jurisdiction
wherein  the  rights or  remedies  are  asserted),  and,  without  limiting  the
foregoing,   Lessor  also  may  exercise,  at  the  direction  of  the  Required
Certificate  Purchasers,  in any  order  one  or  more  or all of the  following
remedies (it being  understood that no remedy herein conferred is intended to be
exclusive of any other  remedy or  remedies,  but each and every remedy shall be
cumulative and shall be in addition to every other remedy given herein or now or
hereafter existing at law or in equity or by statute):  (i) terminate this Lease
by notice in writing to Lessees'  Agent,  but  Lessees  shall  remain  liable as
hereinafter  provided;  (ii) declare the entire  outstanding Lease Balance to be
due  and  payable,   together   with  accrued   unpaid  Rent,   any   Applicable
Administrative  Charge,  and any  other  amounts  payable  under  the  Operative
Documents  (and the  payment  of such  amounts  shall be the joint  and  several
obligations of Lessees);  (iii) enforce the Lien given hereunder pursuant to the
UCC or any other law; (iv) enter upon the premises  where any of the  Collateral
may be and take  possession  of all or any of such  Collateral;  (v)  proceed by
appropriate  court  action or  actions  either at law or in  equity,  to enforce
performance by Lessees of the  applicable  covenants of this Lease or to recover
damages for the breach thereof;  and (vi) require Lessees to assemble and return
the Units as provided below.

     If Lessor  exercises  the option set forth in clause  (vi)  above,  Lessees
shall, at their own expense, forthwith deliver exclusive possession of the Units
to Lessor  for the  benefit of the  Certificate  Purchasers,  at a  location  or
locations designated by Lessor in the 48 contiguous United States, together with
a copy of an inventory  list of the Units then  subject to this Lease,  all then
current  plans,  specifications  and operating,  maintenance  and repair manuals
relating  to the Units that have been  received or prepared by Lessees and their
Affiliates,  appropriately  protected and in the condition required by Article V
hereof (and in any event in condition to be placed in immediate revenue service)
and free and clear of all Liens  (other than the Liens  described in clauses (i)
through (iv) of the definition of Permitted Liens). In addition,  Lessees shall,
for 180 days after redelivery of the Units, maintain (or cause to be maintained)
the Units in the condition required by Article V and free and clear of all Liens
(other than the Liens described in clauses (i) through (iv) of the definition of
Permitted  Liens),  store the Units  without  cost to Lessor or any  Certificate
Purchaser and keep all of the Units insured in accordance with Section 6.2. This
paragraph shall survive termination of this Lease.

     Notwithstanding the foregoing,

          (a) if any Event of Default  described  in Section  8.1(a)  shall have
     occurred and be continuing Lessor may, by notice to Lessees' Agent, declare
     the then outstanding  Lease Balance to be due and payable together with all
     accrued  Accrual Rent, any Applicable  Administrative  Charge,  any amounts
     payable  pursuant to Section 7.7, and any other amounts accrued and payable
     under the Operative Documents (and the payment of such amounts shall be the
     joint and several obligations of Lessees); and

          (b) if any Event of  Default  described  in  Section  8.1(f) or 8.1(g)
     shall have occurred and be continuing,  then the entire  outstanding  Lease
     Balance, any Applicable Administrative Charge, and all accrued Accrual Rent
     and other amounts payable under the Operative Documents shall automatically
     and  immediately  become  due and  payable,  without  presentment,  demand,
     notice,  declaration,  protest or other  requirements  of any kind,  all of
     which are hereby expressly waived.

     Section 8.3. Sale of  Collateral.  In addition to the remedies set forth in
Section  8.2,  if any Event of  Default  shall  occur,  Lessor  may,  but is not
required to, sell the Collateral in one or more sales. Any Certificate Purchaser
and Lessor may purchase  all or any part of the  Collateral  at such sale.  Each
Lessee  acknowledges that sales for cash or on credit to a wholesaler,  retailer
or  user  of  such  Collateral,  or  at  public  or  private  auction,  are  all
commercially  reasonable.  Any notice required by law of intended disposition by
Lessor shall be deemed  reasonably  and properly given if given at least 10 days
before such disposition.

     Section 8.4. Application of Proceeds. The proceeds of such sale or exercise
of other remedies shall be applied in the following order:

          (a) First,  to the payment of costs and  expenses of each  Certificate
     Purchaser  and  Lessor  in  exercising  remedies,   including  expenses  of
     foreclosure or suit, if any, and of any sale, and of all other proper fees,
     expenses, liabilities and advances (including reasonable legal expenses and
     attorneys' fees) of each Certificate Purchaser and Lessor and of all taxes,
     assessments  or liens  superior to the lien of these  presents,  except any
     taxes, assessments or superior lien subject to which any sale of Collateral
     may have been made;

          (b) Second, to the other amounts, except those specified in clause (c)
     below, which under the terms of this Lease have accrued;

          (c) Third, to the aggregate  outstanding  Lease Balance,  plus any due
     but unpaid Administrative Charge or Rent, plus any unpaid interest accruing
     because  of the late  payment of the Lease  Balance  or any  Administrative
     Charge  to the date of  distribution,  in each  case,  in  accordance  with
     Section 3.2 of the Trust Agreement; and

          (d) Fourth,  to the payment of the surplus,  if any, to whomsoever may
     be lawfully  entitled to receive the same  (including  Lessees),  or, if no
     other Person is lawfully entitled to such surplus, to Lessees.

     If there is a  deficiency  in any amounts due  hereunder  after  Lessor has
exercised remedies, Lessees will promptly pay the same to Lessor.

     Section 8.5. Right to Perform  Obligations.  If any Lessee fails to perform
any of its  agreements  contained  herein,  whether  or not an Event of  Default
exists, Lessor may perform such agreement, and the fees and expenses incurred by
Lessor in connection with such performance  together with interest thereon shall
be payable by Lessees upon demand.  Interest on fees and expenses so incurred by
Lessor  shall  accrue as provided  in Section 4.6 from the date such  expense is
incurred until paid in full.

     Section 8.6. Power of Attorney. Each Lessee unconditionally and irrevocably
appoints  Lessor as its true and  lawful  attorney-in-fact,  with full  power of
substitution, to the extent permitted by Applicable Laws and Regulations, in its
name and stead and on its  behalf,  for the  purpose of  effectuating  any sale,
assignment,  transfer  or  delivery  hereunder,  if an Event of Default  occurs,
whether pursuant to foreclosure or power of sale or otherwise, and in connection
therewith  to execute and deliver  all such deeds,  bills of sale,  assignments,
releases  (including releases of this Lease on the records of any Authority) and
other  proper  instruments  as  Lessor  may  reasonably  consider  necessary  or
appropriate.  Each Lessee  ratifies and  confirms all that such  attorney or any
substitute  shall  lawfully do by virtue  hereof.  If requested by Lessor or any
purchaser,  Lessees  shall ratify and confirm any such lawful sale,  assignment,
transfer or delivery by executing and  delivering  to Lessor or such  purchaser,
all deeds, bills of sale, assignments,  releases and other proper instruments to
effect such  ratification  and  confirmation  as may be  designated  in any such
request.

     Section 8.7. Remedies Cumulative; Consents. To the extent permitted by, and
subject to the mandatory requirements of, Applicable Laws and Regulations,  each
and every right,  power and remedy  herein  specifically  given to Lessor or any
Certificate  Purchaser or otherwise in this Lease shall be cumulative  and shall
be in addition to every other right, power and remedy herein  specifically given
or now or hereafter existing at law, in equity or by statute, and each and every
right, power and remedy whether  specifically herein given or otherwise existing
may be  exercised  from  time to time and as often  and in such  order as may be
deemed  expedient by Lessor or the Certificate  Purchasers,  and the exercise or
the  beginning  of the exercise of any power or remedy shall not be construed to
be a waiver of the right to exercise at the same time or  thereafter  any right,
power or remedy.  Lessor's or the Certificate Purchasers' consent to any request
made by Lessees  shall not be deemed to constitute or preclude the necessity for
obtaining Lessor's or the Certificate Purchasers' consent, in the future, to all
similar  requests.  To the extent  permitted by Applicable Laws and Regulations,
each Lessee  hereby  waives any rights now or hereafter  conferred by statute or
otherwise that may require Lessor or the Certificate  Purchasers to sell,  lease
or  otherwise  use the  Units,  any Unit or any Part  thereof in  mitigation  of
Lessor's or the Certificate  Purchasers' damages upon the occurrence of an Event
of  Default  or that  may  otherwise  limit or  modify  any of  Lessor's  or the
Certificate Purchasers' rights or remedies under this Section 8.


                                   Article IX

                                     Lessor

     Section 9.1. Compensation of Lessor.  Lessees shall, on a joint and several
basis, pay Lessor its reasonable fees, costs and expenses for the performance of
Lessor's obligations hereunder.

     Section  9.2.  Limitations.  It is expressly  understood  and agreed by and
among the parties  hereto that,  except as otherwise  provided  herein or in the
other Operative  Documents:  (a) this Lease and the other Operative Documents to
which Lessor is a party are executed by Lessor,  not in its individual  capacity
(except with respect to the  representations and covenants of Lessor in Sections
12.3 and 13.2),  but solely as Lessor under the Trust  Agreement in the exercise
of the power and authority  conferred and vested in it as such Lessor;  (b) each
and all of the undertakings and agreements herein made on the part of Lessor are
each and every one of them made and  intended not as personal  undertakings  and
agreements by Lessor, or for the purpose or with the intention of binding Lessor
personally,  but are made and  intended  for the  purpose  of  binding  only the
Collateral  unless  expressly  provided  otherwise;  (c)  actions to be taken by
Lessor pursuant to its obligations under the Operative Documents may, in certain
circumstances,   be  taken  by  Lessor  only  upon  specific  authority  of  the
Certificate  Purchasers;  (d) nothing contained in the Operative Documents shall
be construed as creating any liability on Lessor, individually or personally, or
any incorporator or any past,  present or future subscriber to the capital stock
of, or stockholder, officer or director, employee or agent of, Lessor to perform
any covenants either express or implied contained herein, all such liability, if
any,  being  expressly  waived by the other  parties  hereto  and by any  Person
claiming by,  through or under them; and (e) so far as Lessor,  individually  or
personally,  is concerned,  the other parties hereto and any Person claiming by,
through or under them shall look  solely to the  Collateral  and Lessees for the
performance of any obligation  under any of the instruments  referred to herein;
provided,  however, that nothing in this Section 9.2 shall be construed to limit
in scope or substance  the general  corporate  liability of Lessor in respect of
its gross negligence or willful misconduct or those representations,  warranties
and covenants of Lessor in its individual capacity set forth herein or in any of
the other agreements contemplated hereby.


                                    Article X

                     Distributions to Certificate Purchasers

     All amounts of money received or realized by Lessor  pursuant to this Lease
which are to be distributed to any Certificate  Purchaser (as distinguished from
Lessees or any other Person) shall be distributed in accordance with Section 3.2
of the Trust Agreement.


                                   Article XI

                                Lease Termination

     Section 11.1.  Lessees' Options.  Not later than 360 days prior to the last
day of the Base Term or any  Renewal  Term then in  effect,  Lessees  shall,  by
delivery of written  notice from  Lessees'  Agent to Lessor and the  Certificate
Purchasers, exercise one of the following options (provided that Lessees may not
exercise  the  Renewal  Option if such  exercise  would  result in more than two
Renewal Terms):

          (a) renew  this  Lease  with  respect  to all,  but not less than all,
     (except with respect to Units for which there has been an early termination
     pursuant  to  Section  11.5)  of  the  Units  then  subject  hereto  for an
     additional  one year Renewal Term (the  "Renewal  Option") on the terms and
     conditions set forth herein and the other Operative Documents; or

          (b) purchase for cash for the Purchase Option Exercise Amount all, but
     not less than all, of the Units then  subject to this Lease on the last day
     of the Base Term or  Renewal  Term with  respect  to which  such  option is
     exercised (the "Purchase Option"); or

          (c)  sell  on  behalf  of the  Certificate  Purchasers  for  cash to a
     purchaser or purchasers not in any way affiliated  with any Lessee all, but
     not less than all, of the Units then  subject to this Lease on the last day
     of the Base Term or of any  Renewal  Term then in effect  with  respect  to
     which such option is exercised (the "Sale Option").  Simultaneously  with a
     sale  pursuant to the Sale Option,  Lessees  shall,  on a joint and several
     basis,  pay  to  Lessor,  as  Supplemental  Rent  for  the  benefit  of the
     Certificate  Purchasers,  from the gross proceeds of the sale of the Units,
     without  deductions  or  expense   reimbursements  (the  "Proceeds"),   the
     aggregate  outstanding  Lease  Balance  as  of  the  Termination  Date  (as
     determined  after any payment of Rent on such date). If the Proceeds exceed
     the aggregate outstanding Lease Balance, Lessees will retain the portion of
     the Proceeds in excess thereof. If the Proceeds are less than the aggregate
     outstanding Lease Balance,  Lessees will, on a joint and several basis, pay
     or will cause to be paid to Lessor, as Supplemental Rent for the benefit of
     the Certificate  Purchasers,  on the  Termination  Date, in addition to the
     Proceeds, the Sale Recourse Amount, it being understood,  however, that the
     amount  payable  pursuant  to this  Section  11.1(c)  shall  in no event be
     construed to limit any other  obligation  of any Lessee under the Operative
     Documents,  including,  without  limitation,  pursuant  to Article  VII and
     Sections 11.3, 11.4, 11.5 and 17.1. The "Sale Recourse Amount" shall be, at
     the  option of  Lessor,  (x) the  Applicable  Percentage  Amount or (y) the
     Recourse Deficiency Amount;  provided,  however, that in no event shall the
     Sale Recourse  Amount  exceed the Lease Balance  (after taking into account
     all payments of Rent and Proceeds  applied against the Lease Balance on the
     Termination Date). Lessor, on behalf of the Certificate  Purchasers,  shall
     notify Lessees' Agent in writing not later than five Business Days prior to
     the  Termination  Date whether the Sale Recourse Amount shall be determined
     pursuant to clause (x) or clause (y) of the preceding sentence. In addition
     to the amount determined to be payable by Lessees pursuant to the foregoing
     provisions of this Section  11.1(c),  Lessees shall, on a joint and several
     basis, pay to Lessor,  for the benefit of the Certificate  Purchasers,  the
     Applicable  Administrative  Charge, if any, on the sum of the Proceeds, the
     Sale Recourse  Amount and any amount payable  pursuant to the last sentence
     of Section 11.4. The obligation of any Lessee to pay the amounts determined
     pursuant to this Section  11.1(c)  shall be a recourse  obligation  of such
     Lessee and shall be payable on the  Termination  Date.  All amounts paid to
     Lessor  pursuant to this Section 11.1(c) shall be distributed in accordance
     with Section 3.2 of the Trust Agreement.

     Section 11.2. Election of Options. Lessees' election of the Purchase Option
will be  irrevocable  at the time  made,  but if  Lessees  fail to make a timely
election,  Lessees will be deemed, in the case of the Base Term and each Renewal
Term then in  effect  (other  than the last  Renewal  Term) to have  irrevocably
elected the Renewal  Option and, in the case of the last Renewal  Term,  Lessees
will be deemed to have irrevocably elected the Purchase Option. In addition, the
Sale Option shall  automatically be revoked if there exists an Incipient Default
or Event of Default at any time after the Sale  Option is  properly  elected and
Lessor shall be entitled to exercise all rights and remedies provided in Article
VIII.  Lessees  may not elect the Sale  Option  or the  Renewal  Option if there
exists on the date the  election  is made an Event of  Default  or an  Incipient
Default.

     Section  11.3.  Sale Option  Procedures.  If Lessees elect the Sale Option,
Lessees shall use their best  commercial  efforts to obtain the highest all cash
purchase  price for the  Units.  All costs  reasonably  related to such sale and
delivery,  including,  without limitation,  the cost of sales agents, removal of
the Units, delivery of documents and Units to any location designated by a buyer
within the continental United States,  certification and testing of the Units in
any location  chosen by the buyer or prospective  buyer,  legal costs,  costs of
notices,  any  advertisement or other similar costs, or other information and of
any  parts,  configurations,  repairs  or  modifications  desired  by a buyer or
prospective buyer shall be borne entirely by Lessees,  without regard to whether
such costs were incurred by Lessor,  Lessees or any potentially qualified buyer,
and shall in no event be paid from any of the Proceeds.  Neither  Lessor nor any
Certificate Purchaser shall have any responsibility for procuring any purchaser.
If,  nevertheless,  Lessor  at  the  direction  of  any  Certificate  Purchaser,
undertakes  any sales  efforts,  Lessees  shall,  on a joint and several  basis,
promptly reimburse Lessor and/or any such Certificate Purchaser for any charges,
costs and  expenses  incurred  in such  effort,  including  any  allocated  time
charges, costs and expenses of internal counsel or other attorneys' fees. Upon a
sale  pursuant  to the Sale  Option,  the  Units  shall be (i) in the  condition
required by Article V (and, in any event, in condition to be placed in immediate
revenue  service),  (ii) free and clear of any Liens (other than Liens described
in clauses (i) through  (iv) of the  definition  of  Permitted  Liens) and (iii)
accompanied by all then current plans,  specifications and operating maintenance
and repair manuals  relating to such Units.  Lessor shall  determine  whether to
accept the highest all cash offer for the Units.  Any purchaser or purchasers of
the  Units  shall  not in any way be  affiliated  with  any  Lessee  or have any
understanding  or  arrangement  with any Lessee  regarding the future use of the
Units.  On the  Termination  Date,  so long as no Event of Default or  Incipient
Default  exists:  (i) Lessees shall  transfer all of Lessees'  right,  title and
interest  in the  Units,  or  cause  the  Units  to be so  transferred,  to such
purchaser or  purchasers,  if any, in  accordance  with all of the terms of this
Lease;  (ii) subject to the  simultaneous  payment by Lessees of all amounts due
under clause (iii) of this sentence, Lessor shall, without recourse or warranty,
except as to the absence of Lessor Liens,  transfer by quitclaim Lessors' right,
title and  interest in and to the Units to such  purchaser  or  purchasers;  and
(iii) Lessees shall, on a joint and several basis,  simultaneously pay to Lessor
all of the amounts contemplated in Section 11.1(c).

     Section 11.4.  Appraisals.  If Lessees exercise the Sale Option and the sum
of the  Proceeds  from the sale of all  Units  subject  to this  Lease  plus the
Applicable Percentage Amount are less than the outstanding Lease Balance, Lessor
(upon  direction from any  Certificate  Purchaser)  shall engage an appraiser of
nationally  recognized standing, at Lessees' expense, to determine (by appraisal
methods satisfactory to the Certificate Purchasers) the Fair Market Value of the
Units then  subject to this Lease as of (a) the first day of any Renewal Term in
which the Sale Option was elected, and (b) the Termination Date. The Appraiser's
conclusion  relating  to the  first  day of the  Renewal  Term  shall be used in
calculating  the "Recourse  Deficiency  Amount".  If the Sale Option is elected,
Lessees will indemnify and hold harmless Lessor and each Certificate  Purchaser,
to the extent the Lease Balance remains  outstanding,  after  application of all
Proceeds and the Applicable Percentage Amount or the Recourse Deficiency Amount,
as applicable,  against any Claims resulting from Lessees' sale of the Units for
less than their Fair Market Value, as of the last day of the Lease Term, without
prior written consent of Lessor.

     Section 11.5. Early Termination.

     (a) Early Termination for Operational  Reasons.  If no Incipient Default or
Event of  Default  shall  exist,  on any  scheduled  Payment  Date  (the  "Early
Termination  Date"), if any Lessee has made a good faith  determination that any
Unit  leased by such Lessee  should be  replaced or removed  from this Lease for
operational  reasons (as  evidenced by a resolution of the Board of Directors of
such Lessee),  upon at least 30 days' advance  written  notice to Lessor and the
Certificate Purchasers, such Lessee may either:

          (i)  purchase  such Unit for a purchase  price  equal to the  Casualty
     Amount of such Unit; or

          (ii) replace such Unit  pursuant to the  following  provisions of this
     Section 11.5.

     If such Lessee has elected to pay the  Casualty  Amount  pursuant to clause
(i) above,  Lessees shall  continue to make all payments of Rent with respect to
such Unit due under this Lease until and including the Early  Termination  Date.
Upon  payment  of the  Casualty  Amount in  respect  of such Unit on such  Early
Termination Date, (x) the remaining  scheduled payments of Capital Rent shall be
proportionately  reduced  by an amount  equal to the  product  of the  scheduled
amount of such  Capital  Rent  payment  (determined  in each  case  prior to the
receipt of such Casualty Amount),  multiplied by the Unit Value Fraction of such
Unit and the Lease  Balance  shall be  appropriately  adjusted  to reflect  such
reduction in the remaining scheduled payments of Capital Rent.

     If any Lessee has given  notice that it intends to replace  such Unit on or
before the Early  Termination  Date, then such Lessee shall make subject to this
Lease, a replacement for such Unit meeting the suitability standards hereinafter
set forth.  To be suitable as a  replacement  Unit,  an item must be of the same
general type, year of construction (or a later year of construction),  function,
utility,  state of repair and operating  condition  (immediately  preceding such
termination  assuming that such Unit had been  maintained in accordance with the
terms of Section 5.3) as the Unit being replaced,  must have a Fair Market Value
of not less than the Fair Market Value  (immediately  preceding such replacement
assuming  that such Unit had been  maintained  in  accordance  with the terms of
Section 5.3) of the Unit being replaced and be free and clear of any Liens other
than Permitted  Liens.  Such Lessee shall cause a Bill of Sale and an Acceptance
Certificate  to  be  executed  and  delivered  to  Lessor  and  the  Certificate
Purchasers  in order to subject such  replacement  item to this Lease,  and upon
such  execution  and  delivery  and the  receipt by Lessor  and the  Certificate
Purchasers  of (i) evidence  reasonably  satisfactory  to them of such  Lessee's
compliance  with the  insurance  provisions  of Section 6.2 with respect to such
replacement  item,  and (ii) an opinion  of  counsel to such  Lessee in form and
substance  reasonably  satisfactory  to Lessor  and the  Certificate  Purchasers
opining,  among  other  things,  to the  effect  that all  appropriate  filings,
recordings  and other  acts have been  taken to  protect  the  right,  title and
interest of Lessor, on behalf of the Certificate Purchasers, in such replacement
item and that no other filing,  recording,  deposit, or giving of notice with or
to any Authority is necessary to protect such right,  title and interest in such
replacement  item,  such  replacement  item  shall be  deemed  a "Unit"  for all
purposes hereof.

     Notwithstanding  anything contained herein to the contrary,  Lessees' right
to exercise  the option set forth in clause (i) of the first  paragraph  of this
Section 11.5 is limited in the aggregate to Units having a Purchase  Price equal
to or less than 10% of the Purchase Price for all Units.

     (b) Early  Purchase  Option.  If no  Incipient  Default or Event of Default
shall exist on any Payment Date (the "Early  Purchase  Date"),  upon at least 30
days' advance  written notice from Lessees' Agent to Lessor and the  Certificate
Purchasers,  Lessees may purchase all but not less than all of the Units subject
to this  Lease  for a  purchase  price  equal to the  entire  outstanding  Lease
Balance, plus all Accrual Rent accrued on the Lease Balance, plus the Applicable
Administrative  Charge on the Lease  Balance,  plus all other  sums then due and
payable  under the  Operative  Documents  by Lessees,  Parent  Guarantor  or any
Subsidiary Guarantor.


                                   Article XII

                         Representations and Warranties

     Section 12.1.  Representations  and  Warranties of Lessees.  As of the date
hereof  and the  Delivery  Date,  each  Lessee  makes  the  representations  and
warranties set forth in this Section 12.1 to each of the other parties hereto.

          (a)  Due  Organization,   etc.  Such  Lessee  is  a  corporation  duly
     organized,  validly  existing  and in good  standing  under the laws of its
     jurisdiction  of  organization.  Such Lessee has the lawful power to own or
     lease its properties and to engage in the business it presently conducts or
     proposes to conduct.  Such Lessee is duly licensed or qualified and in good
     standing in each  jurisdiction  where the property owned or leased by it or
     the nature of the business transacted by it or both makes such licensing or
     qualification  necessary or which its failure to be so qualified would have
     a Material  Adverse Effect  (including each state or other  jurisdiction in
     which the Units or any thereof will be located).

          (b)  Authorization;  No Conflict.  Such Lessee has full power to enter
     into,  execute,  deliver  and carry out this Lease and the other  Operative
     Documents  to which it is a party,  to lease the Units to be leased by such
     Lessee as contemplated  by this Lease and to perform its obligations  under
     the Operative  Documents to which it is a party,  and all such actions have
     been duly authorized by all necessary  proceedings on its part. Neither the
     execution  and delivery of this Lease or the other  Operative  Documents by
     such Lessee,  nor the  consummation of the  transactions  herein or therein
     contemplated or compliance with the terms and provisions  hereof or thereof
     by such Lessee will (i) conflict with, constitute a default under or result
     in any  breach  of (A) the  terms  and  conditions  of the  certificate  of
     incorporation,  bylaws or other organizational  documents of such Lessee or
     (B) any  Applicable  Laws and  Regulations  or any  material  agreement  or
     instrument  or order,  writ,  judgment,  injunction or decree to which such
     Lessee is a party or by which such  Lessee is bound or to which such Lessee
     is subject,  (ii) result in the creation or enforcement of any Lien, charge
     or encumbrance  whatsoever upon any property (now or hereafter acquired) of
     such Lessee (other than Liens  granted  under the  Operative  Documents) or
     (iii)  require any  Governmental  Action by any Authority or any consent or
     approval of any non-governmental  Person (including any action necessary to
     rebut the presumption of fraud  discussed in subsection (f) below),  except
     for (A) the filings and  recordings  listed on Schedule  III to perfect the
     rights of Lessor (for the benefit of the Certificate  Purchasers)  intended
     to be  created  by the  Operative  Documents,  and (B)  those  Governmental
     Actions  required  with  respect  to such  Lessee or any of its  Affiliates
     listed on Schedule IV, each of which have been duly effected and are, or on
     the Delivery Date will be, in full force and effect.

          (c) Enforceability, etc. This Lease has been duly and validly executed
     and delivered by such Lessee,  and each other Operative Document which such
     Lessee is  required to execute and deliver on or after the date hereof will
     have been duly  executed and  delivered by such Lessee on the required date
     of delivery of such Operative Document. This Lease and each other Operative
     Document  constitutes,  or  will  constitute,   legal,  valid  and  binding
     obligations of such Lessee which is or will be a party thereto on and after
     its date of delivery thereof, enforceable against such Lessee in accordance
     with its terms,  except to the extent  that  enforceability  of any of such
     Operative   Document   may   be   limited   by   bankruptcy,    insolvency,
     reorganization,   moratorium   or  other   similar   laws   affecting   the
     enforceability  of  creditors'  rights  generally  or limiting the right of
     specific performance.

          (d)  Litigation.   There  are  no  actions,   suits,   proceedings  or
     investigations  pending or, to the  knowledge  of such  Lessee,  threatened
     against  such  Lessee  at  law  or  equity  before  any   Authority   which
     individually or in the aggregate could  reasonably be expected to result in
     any Material Adverse Effect. Lessee is not in violation of any order, writ,
     injunction  or any  decree  of any  Authority  which  could  reasonably  be
     expected to result in any Material Adverse Effect.

          (e) Title;  Liens.  As of the Delivery Date,  such Lessee has good and
     marketable  title to each Unit to be sold by such Lessee and  delivered  to
     Lessor on the Delivery Date,  free and clear of all Liens  (including,  but
     not  limited  to, any Lien as a result of any right,  claim or  interest in
     favor of any party  owning or holding  any  interest  in the real estate on
     which such Unit is then, or is to be, located) other than Permitted  Liens.
     Such Lessee has not granted,  nor will it grant,  any Lien on any Unit, any
     other  Collateral  or this  Lease,  to any Person  other than Lessor or the
     Certificate  Purchasers or any Permitted Lien; and no Lien,  other than the
     Lien granted to Lessor and the  Certificate  Purchasers  hereunder (and any
     Lien  hereafter   granted  by  Lessor  and  the   Certificate   Purchasers)
     (including, but not limited to, any Lien as a result of any right, claim or
     interest in favor of any party  owning or holding any  interest in the real
     estate on which such Unit is then, or is to be,  located) and any Permitted
     Lien, has attached to the Unit, any other  Collateral or this Lease,  or in
     any manner has affected adversely Lessor's and the Certificate  Purchasers'
     rights and Lien herein.

          (f) Title to Subject Items. On the Delivery Date, Lessor, on behalf of
     the Certificate  Purchasers,  will have good and marketable title to all of
     the Units to be sold by such Lessee, free and clear of all Liens other than
     Permitted  Liens.  Without  limiting the generality of the  foregoing,  the
     transactions  contemplated hereby shall not be deemed fraudulent or void as
     against any present or future creditor of such Lessee under the laws of the
     states where such Units will, on the Delivery  Date, be located,  nor would
     any subsequent  bona fide purchaser from such Lessee of such Units,  in the
     event of any attempted subsequent sale thereof by such Lessee,  acquire any
     title to or rights  therein  superior to Lessor's  title thereto and rights
     therein.

          (g)  Perfection of Security  Interest.  Upon the filing of appropriate
     UCC financing  statements  with the offices  listed on Schedule III hereto,
     the  payment  of any  applicable  fees  and  taxes  relating  to any of the
     foregoing, and the payment of the aggregate Purchase Price for the Units by
     Lessor, Lessor will have an enforceable,  perfected first priority security
     interest of record in the Collateral as against all Persons  including such
     Lessee and its creditors.

          (h) The Units.  The  Purchase  Price for each Unit does not exceed the
     Appraised  Value of such Unit at the time of the sale to  Lessor  hereunder
     and the aggregate  Purchase  Price for all of the Units does not exceed the
     Appraised  Value of all of the  Units  at the  time of the  sale to  Lessor
     hereunder.

          (i) Assuming the accuracy of the  representations  of each Certificate
     Purchaser and Lessor contained in Sections 12.2 and 12.3, respectively, the
     consummation of the transactions  provided for in this Lease and compliance
     by such  Lessee  with the  provisions  hereof and the  Certificates  issued
     hereunder will not involve any Prohibited Transaction.

          (j) No Transfer Taxes. No sales,  use, excise,  transfer or other tax,
     fee or imposition  shall result from the sale,  transfer or purchase of any
     Unit or any Certificate  pursuant to Article II, except such taxes, fees or
     impositions that have been paid in full on or prior to the Delivery Date.

          (k) Rights in Respect of the Units.  Such Lessee is not a party to any
     contract  or  agreement  with  respect  to the sale by such  Lessee  of any
     interest in the Units or any part thereof other than pursuant to this Lease
     and the other Operative Documents to which it is a party.

          (l) Patents,  Trademarks.  Such Lessee has all patents, patent rights,
     trademarks,  service  marks,  trade  names,  copyrights,  licenses or other
     intellectual  property  rights with respect to the Units to be leased by it
     that are necessary for such operation of the Units.

          (m) Defaults,  Casualties,  etc. As of the Delivery Date, no Incipient
     Default,  Event of Default or Casualty has occurred and is  continuing  and
     there is no  action  pending  or, to the best of such  Lessee's  knowledge,
     threatened  by any  Authority  to initiate a Casualty.  As of the  Delivery
     Date, no condition exists that constitutes, or with the giving of notice or
     lapse of time or both would  constitute  an event of default by such Lessee
     under any material indenture,  mortgage,  chattel mortgage,  deed of trust,
     lease,  conditional  sales  contract,  loan or credit  arrangement or other
     material  agreement  or  instrument  to which such  Lessee is a party or by
     which it or any of its properties may be bound which individually or in the
     aggregate  with all such events of default could  reasonably be expected to
     have a Material Adverse Effect.

          (n) Chief Executive Office of Lessees. The principal place of business
     and chief executive  office,  as such terms are used in Section 9-103(3) of
     the UCC, of such Lessee are each located at such Lessee's address set forth
     in the introductory paragraph of this Lease.

          (o)  Compliance  With Law. The Units and the current use and operation
     thereof and thereon do not violate  any  Applicable  Laws and  Regulations,
     including,  without limitation, any thereof relating to occupational safety
     and health or Environmental Laws.

          (p)  Subjection  to  Government  Regulation.  Neither  Lessor  nor any
     Certificate Purchaser will, solely by reason of entering into the Operative
     Documents or consummating the transactions contemplated thereby, (i) become
     subject to ongoing  regulation of its  operations  by any Authority  (other
     than upon  exercise  of  remedies  under this Lease or upon the  expiration
     hereof if Lessees do not  consummate the Purchase  Option);  or (ii) become
     subject to ongoing  regulation  of its  operations  by any  Authority  upon
     exercise of remedies under this Lease or upon the expiration hereof (except
     for  regulation  the  applicability  of which depends upon the existence of
     facts in  addition  to the  ownership  of, or the  holding the Units or any
     interest  therein);  or (iii) be  required to qualify to do business in any
     jurisdiction.

          (q) Investment Company Act. Such Lessee is not an "investment company"
     or a company "controlled" by an "investment company", within the meaning of
     the Investment Company Act of 1940, as amended.

          (r) Public  Utility  Holding  Company.  Such  Lessee is not subject to
     regulation as a "holding  company",  an "affiliate" of a "holding company",
     or a "subsidiary company" of a "holding company", within the meaning of the
     Public Utility Holding Company Act of 1935, as amended.

          (s)  Licenses,  Registrations  and  Permits.  All  material  licenses,
     approvals,  authorizations,  consents and permits  required for the use and
     operation of each Unit have been irrevocably  obtained from the appropriate
     Authorities  having  jurisdiction or from private parties,  as the case may
     be.

          (t) Use of Proceeds; Federal Reserve Regulations.  The proceeds of the
     sale of the Units and the Certificates will be used by Lessees to (i) repay
     a portion of debt outstanding pursuant to an existing synthetic lease, (ii)
     loan to Parent  Guarantor in order for Parent  Guarantor to repay a portion
     of debt outstanding under the Revolving Credit Facility and (iii) for other
     general corporate  purposes.  Neither such Lessee nor any Affiliate of such
     Lessee will, directly or indirectly, use any of the proceeds of the sale of
     the Units or the Certificates for the purpose of purchasing or carrying any
     "margin  security" or "margin stock" within the meaning of Regulation G, T,
     U  or  X  of  the  Board  of  Governors  of  the  Federal  Reserve  System,
     respectively,  or for the purpose of reducing or retiring any  indebtedness
     which was  originally  incurred to  purchase or carry a margin  security or
     margin  stock  or for  any  other  purpose  which  might  cause  any of the
     transactions  contemplated by this Lease or any other Operative Document to
     constitute a "purpose credit" within the meaning of Regulation G, T, U or X
     of the Board of Governors of the Federal Reserve System, or for the purpose
     of  purchasing  or carrying any  security,  and neither such Lessee nor any
     Affiliate  of such  Lessee has taken or will  otherwise  take or permit any
     action by such Lessee or any of its  Affiliates in  connection  with any of
     the transactions contemplated by any of the Operative Documents which would
     involve a violation of Regulation G, T, U, or X, or any other regulation of
     the Board of Governors of the Federal Reserve System.

          (u) Disclosure. The information disclosed in writing by such Lessee or
     any of its  Affiliates  (or any Person  authorized  or employed by any such
     Person as agent or otherwise) to Lessor and the  Certificate  Purchasers in
     connection  with  the  negotiation  of  the  Operative  Documents  and  the
     transactions  contemplated  thereby,  when  taken as a whole with all other
     written  disclosures to such parties, do not contain an untrue statement of
     a material  fact or omit to state a  material  fact  necessary  to make the
     statements herein or therein not misleading. There is no particular fact of
     which such Lessee or any of its  Affiliates has knowledge that has not been
     disclosed  by  such  Lessee  or  any of its  Affiliates  (or by any  Person
     authorized or employed by such Lessee or any of its  Affiliates as agent or
     otherwise) in writing to the  Certificate  Purchasers  that, as far as such
     Lessee or any of its Affiliates can reasonably foresee, could reasonably be
     expected to have a Material Adverse Effect.

          (v) Appraisal  Data. The written  information  provided by such Lessee
     and  its  Affiliates  to the  Appraiser  and  forming  the  basis  for  the
     conclusions  set forth in each  Appraisal,  taken as a whole,  was true and
     correct in all material  respects on the date so given and did not omit any
     information  known  and  available  to such  Lessee  necessary  to make the
     information provided not misleading.

          (w)  Solvency.  The  consummation  by such Lessee of the  transactions
     contemplated  by the  Operative  Documents did not and will not render such
     Lessee  insolvent,  nor  was it  made in  contemplation  of  such  Lessee's
     insolvency;  the value of the assets and  properties of such Lessee at fair
     valuation and at their then present fair salable  value is and,  after such
     transactions,  will  be  greater  than  such  Lessee's  total  liabilities,
     including  contingent  liabilities,  as they become due;  and the  property
     remaining  in  the  hands  of  such  Lessee  was  not  and  will  not be an
     unreasonably small amount of capital.

          (x) Private Offering. Neither such Lessee nor anyone on its behalf has
     offered any interest in this Lease, the Rent, the Certificates or the Units
     or any similar security for sale to, or solicited offers to buy any thereof
     from,  or otherwise  directly or indirectly  approached or negotiated  with
     respect  thereto with, any  prospective  purchaser  other than Lessor,  the
     Certificate   Purchasers   and  not  more  than   thirty-five   (35)  other
     institutional  investors,  each of which was  offered  such  interest  at a
     private sale for  investment  and each of which such Lessee had  reasonable
     grounds to  believe,  and did  believe,  as to Lessor  and the  Certificate
     Purchasers,  after reasonable inquiry does believe,  has such knowledge and
     experience  in  financial  and  business  matters  that  it is  capable  of
     evaluating  the merits and risks of such an investment;  and,  assuming the
     truth and accuracy of the representations set forth in Section 12.2(b), the
     issuance,  sale and delivery of the  Certificates and the interests in this
     Lease  represented  thereby under the  circumstances  contemplated  by this
     Lease do not require the  registration  of such  Certificates  or interests
     under  the  Securities  Act or the  qualification  of any of the  Operative
     Documents under the Trust Indenture Act of 1939, as amended.

          (y)  Brokers,  etc.  Such  Lessee has not  engaged or  authorized  any
     broker,  finder,  investment  banker  or  other  third  party to act on its
     behalf,  directly or indirectly,  as a broker,  finder,  investment banker,
     agent or in any other like capacity in connection with any of the Operative
     Documents or the transactions contemplated thereby, other than BALCAP. Such
     Lessee shall be responsible for, and shall indemnify,  defend and hold such
     Lessor and each Certificate Purchaser harmless from and against any and all
     claims,  liabilities  or  demands by any  Person  for  broker's,  finder's,
     investment banker's or agent's fees, commissions or other entitlements with
     respect  to the  Operative  Documents  and  the  transactions  contemplated
     thereby.

          (z) Real  Property.  Lessee has and will  maintain the right to locate
     each Unit  leased by such  Lessee on, and to enter  onto the  property  and
     disassemble  and remove  each such Unit from each  parcel of real  property
     where the Units  leased by such Lessee  will be  located;  and no such Unit
     will be or become  subject to any Liens  (other than the Lien  described in
     clause (v) of the definition of Permitted  Liens), as a result of such Unit
     being  located  upon such real  property.  The  Units  constitute  and will
     constitute  personal property and no Liens or other claims exist in respect
     of any Unit as a result of any  right,  claim or  interest  in favor of any
     party  owning or holding any interest in the real estate on which such Unit
     is, or is to be,  located  (other than the Lien  described in clause (v) of
     the definition of Permitted Liens).  Any lease of land on which any Unit is
     located  is in full force and  effect  and is for a term that  exceeds  the
     Lease Term.

          (aa) Representations.  The representations and warranties with respect
     to such  Lessee by Parent  Guarantor  in the Parent  Guaranty  are true and
     correct.

          (bb) Interdependent  Business.  Such Lessee's business and investments
     are  interdependent  with  those  of  the  other  Lessees,  the  Subsidiary
     Guarantors  and Parent  Guarantor and such Lessee has received a direct and
     substantial  benefit from the  transactions  contemplated by this Lease and
     the other Operative Documents.

     Section 12.2.  Representations  and Warranties of  Certificate  Purchasers.
Each  Certificate  Purchaser  represents and warrants,  severally and only as to
itself, to each of the other parties hereto as follows:

          (a) ERISA.  Either (i) it is not and will not be purchasing any of its
     interest in the Units or the  Certificates  with the assets of an "employee
     benefit  plan" (as  defined in Section  3(3) of ERISA)  which is subject to
     Title I of ERISA, or a "plan" (as defined in Section 4975(e)(1) of the Code
     or (ii) the acquisition and holding of any Certificate will not result in a
     Prohibited  Transaction,  or (iii) it (A) is an insurance  company,  (B) is
     acquiring its Certificate  with funds held in an insurance  company general
     account (as defined in Section V(e) of the proposed Prohibited  Transaction
     Class Exemption  published on August 22, 1994 at 59 Federal  Register 43134
     (the "Proposed  PTCE") and (C) is acquiring its  Certificate in reliance on
     the  availability  of, and its  qualification  for,  the  exemptive  relief
     contemplated in the Proposed PTCE.

          (b)  Investment  in Units and  Certificates.  (i) It is acquiring  its
     interest  in the Units (as  represented  by the  Certificates)  for its own
     account for investment, and if in the future it should decide to dispose of
     its  interest  in the  Units,  it  understands  that  it may do so  only in
     compliance with the Securities Act and the rules and regulations of the SEC
     thereunder and any applicable state securities laws.  Neither it nor anyone
     authorized  to act on its behalf  has taken or will take any  action  which
     would  subject the issuance or sale of any  Certificate  or any interest in
     the Units, the Collateral or this Lease to the registration requirements of
     Section 5 of the Securities Act. No representation or warranty contained in
     this Section  12.2(b)  shall include or cover any action or inaction of any
     Lessee or any Affiliate thereof whether or not purportedly on behalf of any
     Certificate Purchaser or any of their Affiliates. Subject to the foregoing,
     and subject to the provisions of Article XIV hereof, it is understood among
     the parties that the disposition of each Certificate  Purchaser's  property
     shall be at all times within its control.

          (ii) It has  not  and  will  not  borrow  (other  than  pursuant  to a
     transaction  permitted  by Article XIV) in excess of 97% of its interest in
     the Lease  Balance  in order to  purchase  its  Certificate  pursuant  to a
     transaction  in which the lender or  lenders  have  recourse  solely to its
     Certificate.

     Section  12.3.  Representations  and  Warranties  of  Certificate  Trustee.
Certificate Trustee, in its individual capacity,  hereby represents and warrants
to the other parties as set forth in this Section 12.3.

          (a) Due Organization,  etc.  Certificate Trustee is a national banking
     association duly organized, validly existing and in good standing under the
     laws of the United  States of America;  Certificate  Trustee has full power
     and authority to enter into and perform its obligations under the Operative
     Documents  to which it is or is to be a party  and  each  other  agreement,
     instrument and document to be executed and delivered by it on or before the
     Delivery Date in connection  with or as contemplated by each such Operative
     Document to which it is or is to be a party; and the Operative Documents to
     which  Certificate  Trustee is a party,  have been or will be duly executed
     and delivered by Certificate Trustee.

          (b)  Authorization;   No  Conflict.  The  execution  and  delivery  by
     Certificate Trustee of the Operative Documents to which it is or is to be a
     party, and the performance by Certificate  Trustee of its obligations under
     such Operative Documents, have been duly authorized by all necessary action
     on its part,  and do not and will not: (i)  contravene  any Federal laws or
     laws of the State of Utah  governing  the banking or trust  powers of First
     Security;  (ii)  violate any  provision  of its  charter or by-laws;  (iii)
     result in a breach of or constitute a default under any indenture,  loan or
     credit agreement, or any other agreement or instrument to which Certificate
     Trustee,  either in its individual  capacity,  as Certificate  Trustee,  or
     both, is a party or by which it or its properties may be bound or affected,
     which  breaches or default  would be reasonably  likely to  materially  and
     adversely  affect  the  ability  of  Certificate  Trustee,  either  in  its
     individual  capacity,  as  Certificate  Trustee,  or both,  to perform  its
     obligations  under  any  Operative  Documents  to  which it is or will be a
     party; or (iv) require any authorizations, consents, approvals, licenses or
     formal  exemptions  from, nor any filings,  declarations  or  registrations
     with, any Federal Authority or Authority of the State of Utah governing the
     banking or trust powers of First Security or any consent or approval of any
     non-governmental Person.

          (c) Enforceability,  etc. Each Operative Document to which Certificate
     Trustee,  either in its individual  capacity,  as Certificate  Trustee,  or
     both, is a party  constitutes  the legal,  valid and binding  obligation of
     Certificate  Trustee,  either in its  individual  capacity,  as Certificate
     Trustee,  or both,  enforceable  against  it in  accordance  with the terms
     thereof,  except  as  such  enforceability  may be  limited  by  applicable
     bankruptcy,  insolvency,   reorganization,   moratorium  and  similar  laws
     affecting the  enforcement  of creditors'  rights  generally and by general
     equitable principles.

          (d)  Litigation.  There  is no  action,  proceeding  or  investigation
     pending  or  threatened  which  questions  the  validity  of the  Operative
     Documents  to  which  Lessor  or  Certificate  Trustee,  in its  individual
     capacity,  as Certificate  Trustee, or both, is a party or any action taken
     or to be taken  pursuant to the  Operative  Documents to which  Certificate
     Trustee, in its individual capacity,  as Certificate Trustee, or both, is a
     party.

          (e)  Lessor  Liens.  The Units and the other  Collateral  are free and
     clear of all Lessor Liens attributable to Lessor or to Certificate Trustee,
     in its individual capacity or as Certificate Trustee, or both.

          (f)  Securities  Act. None of Lessor or  Certificate  Trustee,  in its
     individual  capacity  or  as  Certificate  Trustee,  or  both,  nor  anyone
     authorized to act on behalf of any such Person has, directly or indirectly,
     in violation  of Section 5 of the  Securities  Act or any state  securities
     laws, offered or sold any interest in the Certificates, any of the Units or
     this  Lease,  or any  interest  therein,  or in any  security  or lease the
     offering  of  which,  for  purposes  of the  Securities  Act  or any  state
     securities  laws,  would be deemed to be part of the same  offering  as the
     offering of the aforementioned securities or leases, or solicited any offer
     to acquire any of the aforementioned securities or leases.


                                  Article XIII

                                    Covenants

     Section 13.1. Covenants of Lessees.  Each Lessee covenants with each of the
other parties hereto as follows:

          (a) Corporate  Existence,  etc. Subject to clause (e) of Article IV of
     the Parent Guaranty and any transaction permitted thereby pursuant to which
     such Lessee ceases to exist (in which case this  subsection (a) shall apply
     to the surviving  entity of such  transaction),  such Lessee shall preserve
     and keep in full  force and  effect  its  corporate  existence,  rights and
     powers  and   franchises  and  its  power  and  authority  to  perform  its
     obligations under the Operative Documents,  including,  without limitation,
     any necessary  qualification or licensing in any foreign jurisdiction where
     a Unit is located and in any other foreign  jurisdiction  where the failure
     to be so qualified would have a Material Adverse Effect.

          (b) Compliance with Laws. Such Lessee shall comply with all Applicable
     Laws and Regulations (including,  without limitation,  Environmental Laws),
     except  for  such  instances  of  non-compliance   which  would  not  have,
     individually or in the aggregate, a Material Adverse Effect.

          (c) Change of Name or Location.  Such Lessee  shall  furnish to Lessor
     notice  on or  before  the 30th day  prior to any  relocation  of its chief
     executive office or principal place of business,  or change of its name and
     shall  comply with Section  13.1(h)  prior to any such  relocation  or name
     change.

          (d) Notice of Defaults. Promptly after any Responsible Officer of such
     Lessee has learned of the  occurrence  of an Incipient  Default or Event of
     Default, such Lessee shall deliver to Lessor and each Certificate Purchaser
     a certificate  signed by the Chief  Executive  Officer,  President or Chief
     Financial  Officer  of  such  Lessee  setting  forth  the  details  of such
     Incipient  Default or Event of Default  and the  action  which such  Lessee
     proposes to take with respect thereto.

          (e)  Inspection.  Lessor or any  Certificate  Purchaser  may visit and
     inspect the properties (including,  without limitation,  the Units) of such
     Lessee,  examine and make  abstracts  from its books of record and accounts
     (including,  without  limitation,  such Lessee's records  pertaining to the
     Units),  and discuss its affairs,  finances and accounts  with the officers
     and  accountants  of  such  Lessee  (including  but  not  limited  to,  its
     independent  public  accountants),  all at  such  times  as  Lessor  or the
     requesting  Certificate  Purchaser,  as the  case  may be,  may  reasonably
     request; provided that, so long as no Incipient Default or Event of Default
     shall have occurred and be continuing, such inspections shall be limited to
     two per year. Upon such request, such Lessee shall make such properties and
     such  books  of  record  and  accounts  available  to  such  Lessor  or the
     requesting Certificate Purchaser, as the case may be, for inspection.  Such
     Lessee  will pay the  reasonable  expenses  of Lessor  and the  Certificate
     Purchasers  incurred in the exercise of the rights granted pursuant to this
     Section 13.1(e).

          (f) Notice of Litigation.  Promptly after the commencement  thereof or
     promptly after the  determination  thereof,  notice of all actions,  suits,
     proceedings  or  investigations  before  or by any  Authority  or any other
     Person against such Lessee with respect to the Units,  which (x) involve or
     could be reasonably  expected to involve assessments against such Lessee in
     excess of $10,000,000,  individually or in the aggregate,  or (y) involve a
     claim or series of claims which if adversely  determined would constitute a
     Material Adverse Effect.

          (g) Reports to Certificate Purchasers. Such Lessee shall, concurrently
     with any notice,  delivery or other communication to Lessor pursuant to any
     Operative  Document,  deliver  a copy of such  notice,  delivery  or  other
     communication to each Certificate Purchaser at such Certificate Purchaser's
     current address.

          (h) Further Assurances. Such Lessee will, at its expense, promptly and
     duly do any further reasonable act and execute, acknowledge, deliver, file,
     register and record any further documents  (including,  without limitation,
     amendments to this Lease and Uniform  Commercial Code financing  statements
     and  continuation   statements)  as  Lessor  or  the  Required  Certificate
     Purchasers may from time to time  reasonably  request in order to carry out
     more effectively the intent and purposes of this Lease and to establish and
     protect the rights and remedies  created or intended to be created in favor
     of Lessor and the Certificate Purchasers,  including the title to the Units
     and the first priority  security  interest in the Collateral of Lessor,  on
     behalf of the Certificate Purchasers.

          (i) Environmental  Matters. Such Lessee shall: (i) use and operate the
     Units  in  compliance  with all  Environmental  Laws,  keep  all  necessary
     permits,  approvals,   certificates,   licenses  and  other  authorizations
     relating  to  environmental  matters  in  effect  and  remain  in  material
     compliance therewith,  and handle all Hazardous Material in compliance with
     all  applicable  Environmental  Laws;  (ii) promptly  notify Lessor and the
     Certificate  Purchasers  and provide  copies upon  receipt,  of all written
     claims,  complaints,  notices or  inquiries  relating to the  condition  or
     compliance of the Units in so far as they relate to Environmental Laws, and
     promptly cure and have dismissed with prejudice to the  satisfaction of the
     Required  Certificate  Purchasers any actions and  proceedings  relating to
     compliance  with  Environmental  Laws with respect to the Units,  provided,
     however,  that such Lessee may contest in good faith by  Permitted  Contest
     any such actions or  proceedings,  provided  further  that  Lessor,  in its
     individual  capacity and as Lessor,  and the  Certificate  Purchasers  have
     received  reasonably  sufficient  security  from such  Lessee  prior to the
     institution  of any such  Permitted  Contest by such  Lessee as any of them
     shall have  reasonably  requested;  and (iii) provide such  information and
     certifications  which Lessor or any  Certificate  Purchaser may  reasonably
     request from time to time to evidence compliance with this Section 13.1(i).

          (j)  Securities.  Such Lessee  shall not,  nor shall it permit  anyone
     authorized to act on its behalf to, take any action which would subject the
     issuance or sale of the Certificates, any of the Units or the Lease, or any
     security or lease the offering of which, for purposes of the Securities Act
     or any  state  securities  laws,  would  be  deemed  to be part of the same
     offering as the offering of the  aforementioned  items, to the registration
     requirements  of Section 5 of the  Securities  Act or any state  securities
     laws.

          (k) No  Disposition  of the Units.  Except as permitted by Section 5.2
     and Section  11.5,  such Lessee shall not sell,  contract to sell,  assign,
     lease,  transfer,  convey or  otherwise  dispose  of, or permit to be sold,
     assigned, leased, transferred, conveyed or otherwise disposed of, the Units
     or any part thereof.

          (l) Agreement to be bound by Parent Guaranty. Such Lessee acknowledges
     the covenants and  agreements of the Parent  Guaranty and agrees to conduct
     its business and operations in accordance with the covenants and agreements
     contained  in  the  Parent  Guaranty,  including  without  limitation,  the
     provisions of Article IV of the Parent Guaranty.

     Section 13.2. Covenants of Certificate Trustee. Certificate Trustee, in its
individual capacity, covenants with each of the other parties hereto as follows,
it being  understood  that the sole  remedies for the breach of these  covenants
shall be to sue for damages or for specific performance and that any such breach
shall not modify or terminate any Lessee's obligations under Section 4.5:

          (a) so  long  as  this  Lease  remains  in  effect  or so  long as the
     obligations of any Lessee arising hereunder have not been fully and finally
     discharged,   Certificate  Trustee,  in  its  individual  capacity  and  as
     Certificate  Trustee  (including  in its  capacity as Lessor) (i) will keep
     this  Lease  and  all  Collateral  free  and  clear  of  all  Lessor  Liens
     attributable to Certificate  Trustee,  in its individual capacity and/or in
     its capacity as Certificate  Trustee (including in its capacity as Lessor),
     and shall indemnify, reimburse and hold each Certificate Purchaser and each
     Lessee  harmless  from any and all claims,  losses,  damages,  obligations,
     penalties,  liabilities,  demands, suits, or causes of action and all legal
     proceedings,  and any costs or expenses in connection therewith,  including
     reasonable  legal fees and expenses,  of whatever kind and nature,  imposed
     on, incurred by or asserted against any Certificate Purchaser or any Lessee
     in any way  relating  to, or  arising  in any  manner  out of,  failure  by
     Certificate  Trustee in its individual  capacity or as Certificate  Trustee
     (including  in its capacity as Lessor) to comply with this Section  13.2(a)
     and (ii) will not,  provided that no Incipient  Default or Event of Default
     exists,  through  its own  actions,  interfere  with any  Lessee's  (or any
     permitted  sublessee's or assignee's)  rights hereunder with respect to any
     Unit during the term of this Lease,  except as permitted or required by the
     terms of this Lease; and

          (b)  Certificate  Trustee shall apply funds held by it in its capacity
     as  Certificate  Trustee  hereunder as required by this Lease and the Trust
     Agreement.

     Section  13.3.  Covenants  of  Certificate  Purchasers.   Each  Certificate
Purchaser,  severally and not jointly,  covenants with each of the other parties
hereto as follows,  it being understood that the sole remedies for the breach of
these covenants shall be to sue for damages or for specific performance and that
any such breach shall not modify or terminate  any  Lessee's  obligations  under
Section 4.5:

          (a) provided that no Incipient  Default or Event of Default exists, it
     will not,  through its own  actions,  interfere  with any  Lessee's (or any
     permitted  sublessee's or assignee's)  rights hereunder with respect to any
     Unit during the term of this Lease; and

          (b) it will  keep the  Units  free and  clear  from all  Lessor  Liens
     attributable  to it,  provided  that it may  contest  any such  Lessor Lien
     pursuant to a Permitted Contest.


                                   Article XIV

              Assignment By Certificate Purchasers; Participations

     Section 14.1.  Assignments.  (a) All or any of the right, title or interest
and obligations of any Certificate  Purchaser in and to this Lease and the Trust
Agreement  and  the  rights,   benefits,   advantages  and  obligations  of  any
Certificate  Purchaser  hereunder,  including  the rights to receive  payment of
rental or any other payment hereunder,  and the rights,  titles and interests in
and to the Units, may be assigned or transferred by such  Certificate  Purchaser
at any  time by  transfer  of the  Certificate  representing  such  interest  in
accordance with the provisions of this Article XIV; provided,  however, that (a)
such assignee or transferee is a bank or other  financial  institution  that, so
long as no Incipient Default or Event of Default has occurred and is continuing,
is  satisfactory  to Lessees'  Agent,  which consent  shall not be  unreasonably
withheld,  (b) the  Certificate  representing  such  interest and issued to such
assignee  or  transferee  shall be in an amount  not less than the lesser of (i)
$5,000,000 or (ii) the then  outstanding  amount of the Certificate held by such
Certificate Purchaser immediately prior to such transfer or assignment, (c) such
assignment or transfer shall comply with all applicable  securities laws and (d)
each  assignee  or  transferee  represents  to  Lessor,  the  other  Certificate
Purchasers  and  Lessees (i) as set forth in Section  12.2 with  respect to such
transferee  and (ii) that,  and also covenants to such Persons that, it will not
transfer the  Certificate  unless the proposed  transferee  makes the  foregoing
representations and covenants.

     (b) Assumptions of Obligations.  As a condition precedent to any assignment
or transfer  pursuant to this  Section  14.1,  any  transferee  pursuant to this
Section 14.1 shall execute and deliver to Lessees' Agent and Lessor an agreement
in substantially the form of the Assumption Agreement attached hereto as Exhibit
F and thereupon the obligations of the transferring  Certificate Purchaser under
the Operative  Documents  shall be  proportionately  released and reduced to the
extent  of such  transfer.  Upon  any  such  transfer  as  above  provided,  the
transferee  shall be deemed to be bound by all  obligations  (whether or not yet
accrued) under, and to have become a party to, all Operative  Documents to which
its transferor was a party, shall be deemed the "Certificate  Purchaser" for all
purposes  of the  Operative  Documents  and  shall be deemed to have made by the
transferor represented by the interest being conveyed; and each reference herein
and in the other Operative  Documents to the pertinent  "Certificate  Purchaser"
shall thereafter be deemed a reference to the transferee,  to the extent of such
transfer, for all purposes. Upon any such transfer, Lessor shall deliver to each
Certificate Purchaser and Lessees' Agent a new Schedule I to this Lease, revised
to reflect the relevant  information for such new Certificate  Purchaser and the
Commitment of such new Certificate  Purchaser (and the revised Commitment of the
transferor  Certificate  Purchaser if it shall not have  transferred  its entire
interest).

     (c)  Evidence  of  Withholding  Tax  Exemption.  If the  transferee  is not
incorporated  under the laws of the  United  States or any state  thereof,  such
transferee  shall  deliver to Lessees'  Agent a properly  completed and executed
Internal Revenue Service Form 4224 or 1001 or other applicable form, certificate
or document  prescribed  by the Internal  Revenue  Service of the United  States
certifying as to such transferee's compliance with Section 7.2(c).

     Section 14.2.  Participations.  Any  Certificate  Purchaser may at any time
sell to one or more  commercial  banks or other Persons (each of such commercial
banks and other  Persons  being  herein  called a  "Participant")  participating
interests  in all or a portion of its rights and  obligations  under this Lease,
the other Operative  Documents,  the Units or its Certificate  (including all or
any portion of the Rent owing to it); provided, however, that:

          (a) no  participation  contemplated in this Section 14.2 shall relieve
     such  Certificate  Purchaser  from its  obligations  hereunder or under any
     other Operative Document;

          (b) such Certificate Purchaser shall remain solely responsible for the
     performance of its Commitment and other obligations;

          (c)  Lessees  shall  continue to deal  solely and  directly  with such
     Certificate  Purchaser  in  connection  with such  Certificate  Purchaser's
     rights and obligations  under this Lease and the other Operative  Documents
     and such  Certificate  Purchaser  shall have the sole right to enforce  its
     rights under the Operative Documents; and

          (d) no  Participant  shall be  entitled to any  reimbursement  for any
     Taxes,   funding  losses,   additional  costs,  capital  costs  or  reserve
     requirements  pursuant to any of Sections  7.5,  7.6 and 7.8 in excess of a
     proportionate   amount  which  would  have  been  payable  to  the  initial
     Certificate Purchaser from whom such Person directly or indirectly acquired
     its participation.


                                   Article XV

                    Ownership and Grant of Security Interest

     Section 15.1. Grant of Security  Interest.  Title to the Units shall remain
in Lessor,  for the benefit of the Certificate  Purchasers,  as security for the
obligations of each Lessee hereunder and under the other Operative  Documents to
which it is a party  until such  Lessee  has  fulfilled  all of its  obligations
hereunder and thereunder.  Each Lessee hereby assigns,  hypothecates,  transfers
and pledges to Lessor for the benefit of Certificate  Purchasers and Lessor, and
grants to Lessor a security  interest for the benefit of Certificate  Purchasers
and  Lessor  in each  Unit and in each  Sublease  covering  any Unit that may be
entered into from time to time in accordance  with the provisions of this Lease,
and  each  Lessee  hereby  grants  to  Lessor  for the  benefit  of  Certificate
Purchasers  and  Lessor  a  continuing  security  interest  in all of the  other
Collateral,  to secure the payment of all sums due hereunder and under the other
Operative  Documents  to which it is a party  and the  performance  of all other
obligations  hereunder and under the other Operative  Documents to which it is a
party.

     Section 15.2. Retention of Proceeds. If any Lessee would be entitled to any
amount  (including  any Casualty  Recoveries) or title to any Unit hereunder but
for the  existence  of any Event of Default or Incipient  Default,  Lessor shall
hold such  amount or Unit as part of the  Collateral  and shall be  entitled  to
apply such  amounts  against any amounts due  hereunder;  provided,  that Lessor
shall  distribute  such  amount  or  transfer  such  Unit,  to  the  extent  not
theretofore  applied,  in  accordance  with the other terms of this Lease if and
when no Event of Default or Incipient Default exists.


                                   Article XVI

                             [Intentionally Omitted]




                                  Article XVII

                                  Miscellaneous

     Section  17.1.  Payment  of  Transaction  Costs  and  Other  Costs.  If the
transactions  contemplated  hereby are consummated,  Lessees shall,  jointly and
severally,  pay all  Transaction  Costs and the  arrangement  fee  described  in
Section 3.9 in  accordance  with Section 3.9, and in the event the  transactions
contemplated hereby do not close, Lessees shall, jointly and severally, pay such
Transaction  Costs  promptly  upon  receipt of invoices  therefor.  In addition,
Lessees  shall,  jointly  and  severally,   pay  or  reimburse  Lessor  and  the
Certificate Purchasers for all other out-of-pocket costs and expenses (including
allocated fees of internal counsel)  reasonably incurred in connection with: (a)
entering  into,  or  the  giving  or  withholding  of,  any  future  amendments,
supplements,  waivers  or  consents  with  respect  to the  Operative  Documents
(including  without limitation any legal services rendered in connection with or
arising under Section 13.1); (b) any Casualty or termination of the Lease or any
other  Operative  Document;   (c)  the  negotiation  and  documentation  of  any
restructuring  or  "workout",  whether  or not  consummated,  of  any  Operative
Document;  (d) the  enforcement  of the rights or remedies  under the  Operative
Documents;  (e) further assurances  requested pursuant to Section 13.1(h) hereof
or any similar  provision  in other  Operative  Documents;  (f) any  transfer by
Lessor or a  Certificate  Purchaser of any interest in the  Operative  Documents
during the continuance of an Event of Default; (g) the ongoing fees and expenses
of Lessor under the Operative Documents; and (h) the Delivery Date.

     Section 17.2. Effect of Waiver. No delay or omission to exercise any right,
power or remedy accruing to Lessor or any Certificate  Purchaser upon any breach
or default of any Lessee hereunder shall impair any such right,  power or remedy
nor shall it be  construed  to be a waiver of any such breach or default,  or an
acquiescence  therein  or of or in any  similar  breach  or  default  thereafter
occurring,  nor shall any single or  partial  exercise  of any  right,  power or
remedy preclude other or further exercise thereof,  or the exercise of any other
right,  power or remedy, nor shall any waiver of any single breach or default be
deemed a waiver  of any  other  breach  or  default  theretofore  or  thereafter
occurring.  Any waiver,  permit, consent or approval of any kind or character on
the part of Certificate Purchasers or Lessor of any breach or default under this
Lease  must  be  specifically   set  forth  in  writing  and  must  satisfy  the
requirements  set forth in Section 17.5 with respect to approval by  Certificate
Purchasers and Lessor.

     Section  17.5.  Effect  and   Modification.   This  Lease  exclusively  and
completely states the rights of Lessor,  Certificate Purchasers and Lessees with
respect to the leasing of the Units and supersedes all prior agreements, oral or

this Lease or any other Operative  Document shall be valid unless in writing and
signed by Lessor and by Lessees.

The Parties Named on Schedule I
  Attached Hereto

        Re:    Arch Coal, Inc. Lease Intended As Security

Ladies and Gentlemen:

        I am General  Counsel of Apogee Coal  Company,  a Delaware  corporation,
Catenary Coal Company, a Delaware  corporation,  and Hobet Mining,  Inc., a West
Virginia  corporation  (collectively,  "Lessees"),  Arch Coal,  Inc., a Delaware
corporation   ("Parent   Guarantor"),   Allegheny   Land  Company,   a  Delaware
corporation,  Arch Coal Sales Company,  Inc., a Delaware  corporation,  Ark Land
Company,  a Delaware  corporation,  Cumberland  River Coal  Company,  a Delaware
corporation, and Mingo Logan Coal Company, a Delaware corporation (collectively,
"Subsidiary  Guarantors").  I have examined and am familiar with originals of or
copies identified to my satisfaction of the Lease Intended as Security, dated as
of January 15, 1998 (the "Lease"),  among Lessees, First Security Bank, National
Association,  a national  banking  association,  not in its individual  capacity
except  as  specifically  set forth in the Trust  Agreement,  but  solely in its
capacity as Certificate Trustee ("Lessor"), and the Persons listed in Schedule I
thereto,  as  Certificate   Purchasers  (each  a  "Certificate   Purchaser"  and
collectively the "Certificate Purchasers"; provided that no such reference shall
be deemed to refer to any  Person  who is not a holder of a  Certificate  at the
date of  determination,  other than for  purposes  of Article VII of the Lease),
each of the other Operative Documents,  the original or certified certificate or
articles of  incorporation,  as the case may be, and the by-laws of the Lessees,
Subsidiary  Guarantors  and  Parent  Guarantor,  and such  other  documents  and
proceedings  as I have  considered  necessary for the purpose of rendering  this
opinion. In addition,  I have examined and am familiar with such other legal and
factual  matters as I have deemed  necessary  for the purpose of rendering  this
opinion. Capitalized terms used in this opinion and not otherwise defined herein
shall have the  respective  meanings  specified in Article I of the Lease.  This
opinion  is  being  furnished  to you at the  request  of  Lessees,  the  Parent
Guarantor and the Subsidiary Guarantors pursuant to the Operative Documents.

        Reference  in  this  opinion  to  "knowledge"  means  the  knowledge  of
attorneys  in my office  which have  devoted  substantive  attention  to matters
directly related to the Operative Documents.






        In rendering  this opinion I have assumed:  (a) the  genuineness  of the
signatures  on all  documents  and  instruments  (other than the  signatures  of
officers of Lessees, Parent Guarantor and Subsidiary Guarantors on the Operative
Documents to which any Lessee, Parent Guarantor or any Subsidiary Guarantor,  as
the case may be, is a party),  the  authenticity  of all documents  submitted as
originals,  and the  conformity  to  originals  of all  documents  submitted  as
photostatic or certified copies; and (b) that the Operative Documents constitute
the legal, valid and binding  obligations of the respective parties thereto,  if
any, other than Lessees, Parent Guarantor and Subsidiary Guarantors.

        Based upon and subject to the  foregoing  and the  further  limitations,
qualifications and exceptions set forth below, I am of the opinion that:

        1. Each Lessee is a corporation duly organized,  validly existing and in
good  standing  under  the laws of the  state of its  incorporation  and has all
requisite  corporate  power and  authority  to conduct its business as presently
conducted,  to own or hold under lease or  subleases  its  properties,  to enter
into,  execute,  deliver,  and  perform  its  obligations  under  the  Operative
Documents to which it is a party, and is duly qualified as a foreign corporation
authorized to do business and is in good standing in every other jurisdiction in
which its failure to be so  qualified  would have a Material  Adverse  Effect or
prevent the enforcement of contracts to which such Lessee is a party.

        2. Parent  Guarantor is a corporation  duly organized,  validly existing
and in good  standing  under  the  laws of the  State  of  Delaware  and has all
requisite  corporate  power and  authority  to conduct its business as presently
conducted,  to own, lease,  license or use its assets and carry on its business,
to enter into,  execute,  deliver and perform its  obligations  under the Parent
Guaranty  and is  duly  qualified  as a  foreign  corporation  authorized  to do
business  and is in good  standing  in every  other  jurisdiction  in which  its
failure to be so qualified  would have a Material  Adverse Effect or prevent the
enforcement of contracts to which Parent Guarantor is a party.

        3. Each Subsidiary  Guarantor is a corporation  duly organized,  validly
existing and in good standing  under the laws of the state of its  incorporation
and has all requisite  corporate  power and authority to conduct its business as
presently conducted,  to own or hold under lease or sublease its properties,  to
enter into,  execute,  deliver and perform its obligations  under the Subsidiary
Guaranty  and is  duly  qualified  as a  foreign  corporation  authorized  to do
business  and is in good  standing  in every  other  jurisdiction  in which  its
failure to be so qualified  would have a Material  Adverse Effect or prevent the
enforcement of contracts to which such Subsidiary Guarantor is a party.

     4. The execution and delivery by each Lessee of, the  consummation  by such
Lessee of the  transactions  provided for in, and the  compliance by such Lessee
with all of the provisions  of, each  Operative  Document to which it is a party
have been duly  authorized by all necessary  corporate  action on its part;  and
neither  the  execution  and  delivery  thereof,  nor  the  consummation  of the
transactions contemplated thereby (including,  without limitation, the operation
of the Units), nor compliance by such Lessee with any of the terms and






provisions thereof (i) requires any approval of the stockholders of such Lessee,
or  approval  or  consent  of any  trustee  or  holder  of any of such  Lessee's
indebtedness or obligations;  (ii) contravenes or will contravene any applicable
laws currently in effect applicable to or binding upon such Lessee or the Units;
(iii) conflicts with, results in any breach of or constitutes any default under,
or results in the  creation of any Lien (other  than the  respective  rights and
interest of such  Lessee,  Certificate  Purchasers  or Lessor as provided in the
Operative  Documents)  upon  any  of  such  Lessee's  property  under,  (A)  any
indenture,  mortgage,  chattel mortgage, deed of trust, lease, conditional sales
contract,  loan or credit  arrangement or other material agreement or instrument
by which such Lessee or any of its properties may be bound or by which the Units
may be materially adversely affected, (B) such Lessee's corporate charter or (C)
such Lessee's by-laws; or (iv) requires or will require any Governmental Action,
including,  but not limited to, any Governmental  Action to perfect the right of
Certificate  Purchasers  and Lessor  intended  to be  created  by the  Operative
Documents other than as set forth in Paragraph 21 hereof.

        5. The execution and delivery by Parent  Guarantor of, the  consummation
by Parent Guarantor of the  transactions  provided for in, and the compliance by
Parent  Guarantor with all of the  provisions of, the Parent  Guaranty have been
duly authorized by all necessary  corporate  action on its part; and neither the
execution  and  delivery  thereof,  nor  the  consummation  of the  transactions
contemplated  thereby,  nor compliance by Parent Guarantor with any of the terms
and provisions  thereof (i) requires any approval of the  stockholders of Parent
Guarantor,  or  approval  or consent  of any  trustee or holder of any of Parent
Guarantor's indebtedness or obligations (other than that which has been obtained
by Parent  Guarantor);  (ii)  contravenes or will contravene any applicable laws
currently  in effect  applicable  to or binding  upon  Parent  Guarantor;  (iii)
conflicts  with,  results in any breach of or constitutes  any default under, or
results  in the  creation  of any Lien upon any of Parent  Guarantor's  property
under, (A) any indenture,  mortgage,  chattel  mortgage,  deed of trust,  lease,
conditional  sales  contract,  loan or  credit  arrangement  or  other  material
agreement or instrument by which Parent  Guarantor or any of its  properties may
be bound,  (B) Parent  Guarantor's  Certificate of  Incorporation  or (C) Parent
Guarantor's by-laws; or (iv) requires or will require any Governmental Action to
perfect the right of Certificate Purchasers and Lessor intended to be created by
the Operative Documents.

        6. The  execution  and  delivery by each  Subsidiary  Guarantor  of, the
consummation by such Subsidiary  Guarantor of the transactions  provided for in,
and the compliance by such  Subsidiary  Guarantor with all of the provisions of,
the  Subsidiary  Guaranty have been duly  authorized by all necessary  corporate
action on its part;  and neither the  execution  and delivery  thereof,  nor the
consummation of the transactions  contemplated  thereby,  nor compliance by such
Subsidiary  Guarantor with any of the terms and provisions  thereof (i) requires
any approval of the  stockholders of such Subsidiary  Guarantor,  or approval or
consent  of  any  trustee  or  holder  of  any of  such  Subsidiary  Guarantor's
indebtedness or obligations;  (ii) contravenes or will contravene any applicable
laws  currently  in  effect  applicable  to  or  binding  upon  such  Subsidiary
Guarantor;  (iii)  conflicts  with,  results in any breach of or constitutes any
default  under,  or  results  in the  creation  of any  Lien  upon  any of  such
Subsidiary Guarantor's property under, (A) any indenture, mortgage, chattel






mortgage,  deed of trust,  lease,  conditional  sales  contract,  loan or credit
arrangement or other material  agreement or instrument by which such  Subsidiary
Guarantor or any of its properties may be bound, (B) such Subsidiary Guarantor's
corporate charter or (C) such Subsidiary  Guarantor's  by-laws; or (iv) requires
or will  require any  Governmental  Action to perfect  the right of  Certificate
Purchasers and Lessor intended to be created by the Operative Documents.

        7. Each Operative Document to which each Lessee is a party has been duly
executed  and  delivered  by such Lessee and  constitutes  its legal,  valid and
binding  obligation,  enforceable  against  such Lessee in  accordance  with its
terms,  except as such  enforceability may be limited by applicable  bankruptcy,
insolvency and similar laws affecting creditors' rights generally and by general
equitable principles.

        8. The Subsidiary  Guaranty has been duly executed and delivered by each
Subsidiary  Guarantor and constitutes its legal,  valid and binding  obligation,
enforceable  against such  Subsidiary  Guarantor in  accordance  with its terms,
except  as  such  enforceability  may  be  limited  by  applicable   bankruptcy,
insolvency and similar laws affecting creditors' rights generally and by general
equitable principles.

        9. The Parent  Guaranty has been duly  executed and  delivered by Parent
Guarantor and constitutes its legal, valid and binding  obligation,  enforceable
against  Parent  Guarantor  in  accordance  with  its  terms,   except  as  such
enforceability may be limited by applicable  bankruptcy,  insolvency and similar
laws affecting creditors' rights generally and by general equitable principles.

        10. There is no action,  proceeding or investigation  pending or, to the
best of my knowledge,  threatened  which questions the validity of the Operative
Documents  to which  any  Lessee is a party or any  action  taken or to be taken
pursuant thereto; nor is any action,  proceeding or investigation pending or, to
the best of my knowledge, threatened against any Lessee or its property which is
reasonably  likely  to  result,  either  in any case or in the  aggregate,  in a
Material Adverse Effect.

        11. There is no action,  proceeding or investigation  pending or, to the
best of my  knowledge,  threatened  which  questions  the validity of the Parent
Guaranty  or  Subsidiary  Guaranty or any action  taken or to be taken  pursuant
thereto; nor is any action,  proceeding or investigation pending or, to the best
of my  knowledge,  threatened  against any Parent  Guarantor  or any  Subsidiary
Guarantor  or its  respective  property  which is  reasonably  likely to result,
either in any case or in the aggregate, in a Material Adverse Effect.

        12. No authorizations,  consent,  approval,  license or formal exemption
from, nor any filing,  declaration or  registration  with, any Authority  (other
than  approval of the Board of Directors of each Lessee which has been  obtained
prior  to the  date  hereof)  is or will be  required  in  connection  with  the
execution  and  delivery  by such  Lessee  of the  Operative  Documents,  or the
performance by such Lessee of its obligations under such Operative  Documents or
the ownership, operation and maintenance of the Units as contemplated by the






Operative Documents.

        13. No authorizations,  consent,  approval,  license or formal exemption
from, nor any filing,  declaration or  registration  with, any Authority  (other
than approval of the Board of Directors of Parent  Guarantor or each  Subsidiary
Guarantor, as the case may be, which has been obtained prior to the date hereof)
is or will be required in  connection  with the execution and delivery by Parent
Guarantor  or such  Subsidiary  Guarantor of the Parent  Guaranty or  Subsidiary
Guaranty,  as the case may be, or the  performance  by Parent  Guarantor or such
Subsidiary  Guarantor of its  obligations  under Parent  Guaranty or  Subsidiary
Guaranty, as the case may be.

        14. None of any Lessee, Parent Guarantor nor any Subsidiary Guarantor is
an "investment  company" or a company  "controlled"  by an "investment  company"
within the  meaning of the  Investment  Company  Act of 1940,  as  amended.  The
proceeds of the sale of the Units and the issuance of the Certificates,  if used
in accordance  with the terms of the Operative  Documents,  will not result in a
violation of  Regulations  G. T. U or X of the Board of Governors of the Federal
Reserve System.

        15. None of any Lessee, Parent Guarantor nor any Subsidiary Guarantor is
subject to  regulation  as a "holding  company,"  an  "affiliate"  of a "holding
company," or a "subsidiary  company" of a "holding  company," within the meaning
of the Public Utility Holding Company Act of 1935, as amended.

        16. The registration of the Certificates or the interests of Certificate
Purchasers  under the Securities Act of 1933, as amended,  is not required under
the  circumstances  contemplated  by  the  Lease;  and  no  qualification  of an
indenture in respect of such Certificates or interests under the Trust Indenture
Act of 1939, as amended, is required in connection therewith.

        17. The Lease is in form sufficient to create a valid security  interest
under  Article 9 of the UCC in favor of Lessor for the  benefit  of  Certificate
Purchasers,  as security  for  payment of each  Lessee's  obligations  under the
Lease,  in those  items  and  types  of  Collateral  which  are  subject  to the
provisions of Article 9 of the UCC.

        18. Neither Lessor nor any  Certificate  Purchaser will become solely by
reason  of  entering  into the  Lease or the  consummation  of the  transactions
contemplated  thereby  (other than upon the exercise of remedies under the Lease
or upon the expiration  thereof) subject to ongoing regulation of its operations
by any Authority.

        19. The Bills of Sale are in form sufficient under the laws of the State
of Missouri to convey valid title to the property described therein to Lessor.

        20.  Each UCC  financing  statement  listed on  Schedule  A hereto is in
proper form for  filing,  and upon the due filing of such  financing  statements
with the offices listed on Schedule A hereto,  the security  interest of Lessor,
on behalf of Certificate Purchasers, in all






the Collateral will be perfected to the extent that a security  interest in such
Collateral may be perfected  under the UCC by so filing,  and the description of
such  Collateral   therein  is  adequate.   No  other  filing,   recordation  or
registration  is necessary under the UCC in order to perfect  Lessor's  security
interest in such Collateral.

        21. The payment by Lessees and the receipt by Lessor, for the benefit of
Certificate  Purchasers,  of the  Basic  Rent,  Supplemental  Rent and all other
amounts,  fees or  interest  due and  payable  under  the  Lease  and the  other
Operative  Documents and any transactions  described  therein,  and any interest
rate cap fee paid or payable to Certificate Purchasers or their Affiliates,  are
not  usurious  under or  otherwise  in  violation  of the  laws of the  State of
Missouri.

        22. No state or local  recording  tax,  transfer tax, stamp tax or other
similar fee, tax or  governmental  charge is required to be paid to the State of
Missouri or any political  subdivision thereof in connection with the execution,
delivery,  filing or recording of the Operative Documents or the transfer of the
Units,  other than statutory  filing and recording fees that are to be paid upon
the filing and recording,  as applicable,  of the UCC financing statements filed
in connection with the transactions  contemplated by the Operative Documents and
transfer  taxes that are to be paid by Lessees upon the transfer of the Units on
the Delivery Date.

        23.  In an  action  or  proceeding  arising  out of or  relating  to the
Operative Documents in any court in the State of Missouri (including any federal
court located in such state),  such court will  recognize and give effect to the
provisions  therein  wherein  the  parties  agree that such  documents  shall be
governed by and construed in accordance  with the laws of the State of Illinois.
I advise  you that a court  sitting in the State of  Missouri  would look to the
conflict of laws  principles  of the State of Missouri  to  determine  which law
governs.  Under  Missouri law the parties to  agreements  such as the  Operative
Documents  may agree  that such  agreements  shall be  governed  by the law of a
particular  jurisdiction  so long as some element of such  agreement is property
referable to that  jurisdiction.  Courts applying conflict of laws principles of
the State of Missouri have not enforced  agreements that the law of a particular
jurisdiction  governs  an  agreement  when  there was no  logical  basis for the
agreement, when the agreement was made to evade otherwise applicable law or when
the agreement  infringed upon a fundamental  policy of the State of Missouri.  I
have assumed that the basis for the  selection  of the  substantive  laws of the
State of Illinois as the governing  law of the  Operative  Documents is that the
Operative  Documents were negotiated and the transactions closed in Illinois and
that the parties have not selected  Illinois law in an effort to avoid otherwise
applicable  Missouri law. I am not aware of any fundamental  policy of the State
of Missouri  which would be  infringed  by the  selection of Illinois law as the
governing law of the Operative Documents under those circumstances. Accordingly,
assuming  a court  sitting in the State of  Missouri  would find that there is a
logical  basis for the  parties'  choice of Illinois  law, I believe  such court
should give effect thereto.

        24. Assuming the due authorization,  execution and delivery of the Trust
Agreement by the parties thereto,  (i) the Trust Agreement  constitutes a legal,
valid, binding and effective






agreement and declaration of trust by First Security  enforceable  against First
Security  in  accordance  with the  terms  thereof  and  (ii)  the  Certificates
constitute  the  legal,   valid  and  binding   obligations  of  First  Security
enforceable against First Security in accordance with their terms.

        The opinions contained herein are subject to the following  limitations,
assumptions and qualifications:

        A. The scope and  enforceability of security interests in the collateral
perfected under the UCC are subject to the following:  (i) as to dispositions of
collateral authorized by a secured party and as to proceeds, the limitations set
forth in  Section  9306 of the UCC,  (ii) the  rights  of buyers of goods as set
forth in  Section  9307 of the UCC,  (iii) the rights of  purchasers  of chattel
paper and  instruments  as set forth in Section 9308 of the UCC, (iv) the rights
of purchasers of  instruments  and documents as set forth in Section 9309 of the
UCC, (v) as to accessions, the limitations set forth in Section 9314 of the UCC,
(vi) as to products, the limitations set forth in Section 9315 of the UCC, (vii)
any  right,  defense  or claim of an  account  debtor to which the  rights of an
assignee  would be subject  under Section 9318 of the UCC, and (viii) any right,
defense or claim of a bona fide purchaser under Section 8313(b) of the UCC.

        B. This  opinion is based on the states of law and fact as they exist on
the date hereof.  This  opinion is not  rendered  with respect to any laws other
than the Securities Act, the laws of the State of Missouri,  federal laws of the
United States of America,  the General Corporation Law of the States of Delaware
and West Virginia and the UCC of the State of Illinois, it being understood that
I am not  admitted  to the  practice  of law in the  States  of  Delaware,  West
Virginia and Illinois.  I note that the Operative  Documents  provide that it is
governed  by  and  is to be  construed  and  enforced  in  accordance  with  the
substantive  laws of the State of Illinois without giving effect to conflicts of
law  principles.  However,  in rendering the opinions  expressed  above,  I have
assumed,  with  your  permission,  that  the  substantive  laws of the  State of
Illinois are identical to the  substantive  laws of the State of Missouri in all
respects  relevant to such  opinions  and,  except as set forth in  paragraph 23
above, I express no opinion as to which law any court construing any of the said
agreements would apply.

        I am licensed to practice law in the States of Kentucky and Missouri.

        Only you,  your  successors,  your  participants  in and assigns of, the
Operative Documents and your and their counsel may rely upon this opinion letter
and  only in  connection  with  the  Operative  Documents  and the  transactions
contemplated hereby.

                                      Very truly yours,









                          EXHIBIT C-2 TO LEASE INTENDED AS SECURITY
                                 DATED AS OF JANUARY 15, 1998

                               FORM OF OPINION OF LOCAL COUNSEL

        1. Hobet Mining Inc. is a corporation  duly organized,  validly existing
and in good standing  under the laws of the State of West  Virginia.  Each other
Lessee is duly qualified as a foreign corporation  authorized to do business and
is in good standing in the State of West Virginia.

        2.  Neither  the  execution  and  delivery  by each  Lessee  of, nor the
consummation  by such  Lessee  of the  transactions  provided  for  in,  nor the
compliance by such Lessee with all of the provisions of, each Operative Document
to which it is a party  (including,  without  limitation,  the  operation of the
Units) (i)  contravenes or will  contravene any Applicable  Laws and Regulations
currently in effect  applicable to or binding upon such Lessee or the Units;  or
(ii)  requires  or will  require any  Governmental  Action,  including,  but not
limited  to,  any  Governmental  Action  to  perfect  the  right of  Certificate
Purchasers and Lessor  intended to be created by the Operative  Documents  other
than as set forth in Paragraph 9 hereof.

        3. The Lease  constitutes  the legal,  valid binding  obligation of each
Lessee,  enforceable against such Lessee in accordance with its terms, except as
such  enforceability  may be limited by applicable  bankruptcy,  insolvency  and
similar laws  affecting  creditors'  rights  generally and by general  equitable
principles.

        4. No  authorizations,  consent,  approval,  license or formal exemption
from,  nor any filing,  declaration or  registration  with, any Authority of the
State  of West  Virginia  or any  political  subdivision  thereof  is or will be
required in  connection  with the execution and delivery by Lessees of the Lease
and the Bills of Sale, or the performance by Lessees of their  obligations under
the Lease and the Bills of Sale or the ownership,  operation and  maintenance of
the Units as contemplated by the Lease.

        5. The Lease creates a valid security interest under the UCC in favor of
Lessor for the benefit of  Certificate  Purchasers,  as security  for payment of
each Lessee's  obligations under the Lease, in all of each Lessee's right, title
and interest in and to the Collateral.

        6. Neither  Lessor nor any  Certificate  Purchaser will become solely by
reason  of  entering  into  the  Lease  or  the   consummation  of  transactions
contemplated  thereby  (other than upon the exercise of remedies under the Lease
or upon the expiration  thereof) subject to ongoing regulation of its operations
by any  Authority  of the State of West  Virginia or any  political  subdivision
thereof.

        7. Neither First Security Bank, National Association nor any Certificate
Purchaser is required under the laws of the State of West Virginia to qualify as
a foreign  corporation,  foreign trust company or otherwise in the State of West
Virginia solely as a result of its






execution,  delivery and performance of the Lease. First Security Bank, National
Association is eligible to act as a fiduciary in the State of West Virginia.

        8. The Bills of Sale are in form sufficient  under the laws of the State
of West  Virginia to convey  valid title to the  property  described  therein to
Lessor.

        9. Each UCC financing statement listed on Schedule A hereto is in proper
form for  filing,  and upon the  filing of such  financing  statements  with the
offices listed on Schedule A hereto,  the security interest of Lessor, on behalf
of Certificate Purchasers, in all the Collateral will be perfected to the extent
that a security interest in such Collateral may be perfected under the UCC by so
filing,  and the  description of such Collateral  therein is adequate.  No other
filing,  recordation or registration  is necessary in order to perfect  Lessor's
security interest in such Collateral under the UCC.

        10. The payment by Lessees and the receipt by Lessor, for the benefit of
Certificate  Purchasers,  of the  Basic  Rent,  Supplemental  Rent  and  all the
amounts,  fees or interest due and payable under the Lease and any  transactions
described therein,  and any interest rate cap fee paid or payable to Certificate
Purchasers or their Affiliates, are not usurious under or otherwise in violation
of the laws of the State of West Virginia.

        11. No state or local recording tax, stamp tax or other similar fee, tax
or  governmental  charge is required to be paid to the State of West Virginia or
any political  subdivision  thereof in connection with the execution,  delivery,
filing or  recording  of the  Operative  Documents or the transfer of the Units,
other  than  statutory  filing and  recording  fees that are to be paid upon the
filing and recording,  as applicable,  of the UCC financing  statements filed in
connection with the  transactions  contemplated  by the Operative  Documents and
transfer  taxes to be paid by  Lessees  upon the  transfer  of the  Units on the
Delivery Date.

        12. The  express  choice of laws of the State of  Illinois to govern the
Lease is enforceable and will be recognized by West Virginia courts.

        13. The Units will be treated  as  "personal  property"  and will not be
treated as "real  property" or "fixtures"  constituting  a part of or affixed to
real estate under the laws of the State of West Virginia, and accordingly, it is
not necessary to file any fixture  filings under the UCC in order to perfect any
right,  title or interest  of the Lessor or the  Certificate  Purchasers  in the
Units.

         NOTE: Opinion to cover the laws of the State of West Virginia.

                                  DATED AS OF JANUARY 15, 1998

                    FORM OF OPINION OF CERTIFICATE TRUSTEE'S SPECIAL COUNSEL













                                        January ___,1998

To Each of the Persons
Listed on Schedule A
Attached Hereto


Re:     ARCH COAL TRUST NO. 1998-1

Dear Sir or Madam:

We have  acted as  counsel  to First  Security  Bank,  National  Association,  a
national banking association,  in its individual capacity ("First Security") and
in its capacity as Certificate  Trustee (the "Certificate  Trustee") under Trust
Agreement  (Arch Coal Trust No. 1998-1) dated as of January 15, 1998 (the "Trust
Agreement"), among First Security, the Certificate Trustee and the Persons named
on Schedule I thereto as Certificate Purchasers (the "Certificate  Purchasers"),
in  connection  with the  transaction  contemplated  by the  Lease  Intended  as
Security dated as of January 15, 1998 (the "Lease"),  among Apogee Coal Company,
Catenary  Coal  Company and Hobet  Mining,  Inc.,  as Lessees,  the  Certificate
Trustee as Lessor and the Certificate Purchasers.

In  that  connection,  we have  examined  the  Trust  Agreement  and the  Lease,
Certificates  and the other  related  documents  to which First  Security or the
Certificate Trustee, as applicable,  is a party (the "Operative Documents").  We
have also  examined  such  other  documents,  records,  matters of law and other
matters we have  considered  necessary in connection  with the expression of the
opinions hereinafter set forth.  Capitalized terms used herein and not otherwise
defined herein shall have the meanings specified in the Lease.









Based upon the foregoing, we are of the opinion that:

        1. First  Security is a national  banking  association  duly  organized,
        validly  existing  and in good  standing  under  the laws of the  United
        States of America,  is  authorized  to transact  the business of banking
        under the laws of the United  States of  America  and has full power and
        authority  to execute,  deliver and  perform its  obligations  under the
        Trust Agreement and, acting pursuant thereto, the Operative Documents.

        2. First Security has duly authorized,  executed and delivered the Trust
        Agreement  and,  to  the  extent  specifically   provided  therein,  the
        Operative Documents, and each such document constitutes the legal, valid
        and binding  obligation  of First  Security,  enforceable  against it in
        accordance with the terms thereof.

        3. The Certificate Trustee is duly authorized under the Trust. Agreement
        to execute,  deliver and perform each of the  Operative  Documents,  has
        duly executed and delivered each of the Operative  Moments and each such
        Operative Document  constitutes a regale valid and binding obligation of
        the Certificate Trustee,  enforceable against the Certificate Trustee in
        accordance with its terms.  The  Certificates  issued on the date hereof
        have  been  duly  issued,  executed  and  delivered  by the  Certificate
        Trustee, pursuant to authorization contained in the Trust Agreement, and
        constitute  legal,  valid and  binding  obligations  of the  Certificate
        Trustee,  enforceable against the Certificate Trustee In accordance with
        their terms and the terms of the Trust Agreement.

        4. The Trust  Agreement  duly creates a legal and valid trust under Utah
        law; the trust created by the Trust Agreement  exists for the benefit of
        the  Certificate  Purchasers  as  provided  therein  and creates for the
        benefit of the  Certificate  Purchasers the interest in the Trust Estate
        which the Trust Agreement by its terms purports to create.

        5. Neither the  execution,  delivery or performance by First Security or
        the Certificate Trustee, as the case may be, of the Operative Documents,
        the  consummation by First Security or the Certificate  Trustee,  as the
        case may be, of any of the  transactions  contemplated  thereby  nor the
        compliance by First Security or the Certificate Trustee, as the case may
        be,  with any of the terms  and  provisions  thereof  (i)  requires  any
        approval  of its  stockholders,  or any  consent or  approval  of or the
        giving of notice to any  trustees  or  holders  of any  indebtedness  or
        obligations of it known to us, (ii) violates its articles of association
        or by-laws,  or  contravenes  or will  contravene  any  provision of, or
        constitutes a default under,  or results in any breach of, or results in
        the  creation of any Lien (other than as permitted  under the  Operative
        Documents),  upon  property  under,  any  indenture,  mortgage,  chattel
        mortgage, deed of trust, conditional sales contract, bank loan or credit
        agreement,  license or other agreement or instrument, in each case known
        to us,  to  which  it is a  party  or by  which  it is  bound  or  (iii)
        contravenes  any Utah  applicable  law or United States  applicable  law
        governing the banking or trust powers of First  Security or any judgment
        or order, in each case, known to us applicable to or binding on it.

        6. No consent, approval, order or authorization of, giving of notice to,
        or  registration  with, or taking of any other action in respect of, any
        Utah  governmental  authority or United  States  governmental  authority
        regulating  the baking or trust powers of First Security is required for
        the execution,  delivery,  validity or  enforceability  of the Operative
        Documents,  or the carrying out by,  First  Security or the  Certificate
        Trustee, as the case away be, of any of the transactions contemplated by
        the Operative Documents,  other than any such consent,  approval, order,
        authorization, registration, notice or action as has been duly obtained,
        gives or taken.

                                             C-3-2






        8. There are no fees,  taxes or other charges  payable by First Security
        or the Certificate Trustee imposed by the State of Utah or any political
        subdivision  or  taxing   authority   thereof  in  connection  with  the
        execution, delivery and performance by First Security or the Certificate
        Trustee  of the  Operative  Documents  (other  than  taxes  based  on or
        measured by any fees or compensation received by First Security,  acting
        as the Certificate Trustee, for services rendered in connection with the
        transactions  contemplated  by the Operative  Documents)  solely because
        First Security or the Certificate  Trustee, as the case may be, performs
        certain of its  obligations  under the Trust Agreement and the Operative
        Documents in Salt Lake City or the State of Utah.

        9. The Certificate Trustee has received such titles to the Units as were
        conveyed  to it by Lessees,  subject to the rights of Lessees  under the
        Lease  and to our  knowledge,  there  exist  no  liens  or  encumbrances
        affecting the right,  title and interest of the  Certificate  Trustee in
        and to the Trust Estate resulting from claims against First Security not
        related to the  ownership of the Trust  Estate or any other  transaction
        contemplated by the Trust Agreement and the Operative Documents.

        10. There are no proceedings  pending or, to our  knowledge,  threatened
        and,  to  our  knowledge,  there  is no  existing  basis  for  any  such
        proceedings  against or  affecting  First  Security  or the  Certificate
        Trustee,  as the case may be,  in or  before  any  court or  before  any
        governmental  authority  or  arbitration  board or  tribunal  which,  if
        adversely determined, might, individually or in the aggregate, adversely
        affect  or impair  the  ability  of First  Security  or the  Certificate
        Trustee,  as the case may be, to enter into or to perform in obligations
        under the Trust Agreement or the Operative Documents.

The foregoing opinions are subject to the following assumptions,  exceptions and
qualifications:

        A. The  foregoing  opinions are limited to the laws of the State of Utah
and the federal laws of the United  States of America  governing the banking and
trust powers of First Security.  In addition,  without limiting the foregoing we
express no opinion with respect to (i) federal  securities  laws,  including the
Securities  Act of 1933,  as amended,  the  Securities  Exchange Act of 1934, as
amended,  and the  Trust  Indenture  Act of  1939,  as  amended  or  (ii)  state
securities  or blue sky laws.  Insofar as the foregoing  opinions  relate to the
legally, validly, binding effect and enforceability of the documents involved in
these  transactions,  which by their  terms are  governed by the laws of a state
other than Utah, we have assumed that such documents  constitute  legal,  valid,
binding and  enforceable  agreements  under the laws of such other state,  as to
which we express no opinion.

        B. The foregoing  opinions  regarding  enforceability of any document or
instrument are subject to (i)  applicable  bankruptcy,  insolvency,  moratorium,
reorganization,  receivership and similar laws affecting the rights and remedies
of creditors  generally,  and (ii) general  principles of equity,  regardless of
whether such enforceability is considered in a proceeding in equity or at law.

        C. As to the documents involved in these  transactions,  we have assumed
that each is a legal, valid and binding obligation of each party thereto,  other
than First Security or the Certificate  Trustee, and is enforceable against each
such party in accordance with their respective terms.

        D. We have  assumed  that  all  signatures,  other  than  those  of the
Certificate Trustee or First Security,  on documents and instruments involved in
these transactions are genuine,  that all documents and instruments submitted to
us as originals are authentic,  and that all documents and instruments submitted
to  US  as  copies  conform  with  the  originals,   which  facts  we  have  not
independently verified.

                                              C-3-3






        E. We do not purport to be experts in respect of, or express any opinion
concerning laws, rules or regulations applicable to the particular nature of the

                  FORM OF OPINION OF CERTIFICATE PURCHASER'S SPECIAL COUNSEL

                                      January ____, 1998

To the Parties Listed on
the Attached Schedule

        Re:    Synthetic Lease of Above-Ground Mining Equipment
               (Arch Coal. Inc.)

Ladies and Gentlemen:

        We have  acted  as your  special  counsel  in  connection  with (i) your
execution and delivery of the Lease Intended as Security dated as of January 15,
1998 (the "Lease")  among Apogee Coal  Company,  Catenary Coal Company and Hobet
Mining,   Inc.   (collectively,   "Lessees"),   First  Security  Bank,  National
Association,  individually  ("First  Security")  and as trustee  under Arch Coal
Trust 1998-1 ("Certificate  Trustee"),  providing,  among other things, for your
commitment  to  purchase  up  to  $75,000,000   aggregate  principal  amount  of
Certificates of Certificate  Trustee;  and (ii) your purchase on the date hereof
of $ in aggregate  principal amount of the Certificates.  Capitalized terms used
herein and not otherwise defined herein shall have the meanings set forth in the
Lease.

        In that connection, we have examined executed counterparts of the Lease,
Trust Agreement,  the Subsidiary Guaranty and the Parent Guaranty  (collectively
referred  to in this  opinion  as the  "Operative  Agreements").  The  Operative
Agreements  to which  Lessees are a party are referred to in this opinion as the
"Lessee  Agreements".  We have also examined the Certificates  issued to each of
you on this date.

        We have also examined such other documents,  records, matters of law and
other matters as we have considered  necessary in connection with the expression
of the opinions hereinafter set forth. We have also relied upon the certificates
of appropriate persons.

        Based upon the foregoing, we are of the opinion that:

        1. Each Lessee is a  corporation  validly  existing and in good standing
under the laws of the state of its  incorporation and has the corporate power to
enter into and perform the Lessee Agreements.

        2.  Parent  Guarantor  is a  corporation  validly  existing  and in good
standing under the laws of the State of Delaware and has the corporate  power to
enter into and perform the Parent Guaranty.





        3. Each Subsidiary  Guarantor is a corporation  validly  existing and in
good  standing  under  the laws of the  state of its  incorporation  and has the
corporate power to enter into and perform the Subsidiary Guaranty.

        4.  Each  Lessee  Agreement  has  been  duly  authorized,  executed  and
delivered by each Lessee and constitutes the legal, valid and binding obligation
of such Lessee  enforceable  against  such Lessee in  accordance  with the terms
thereof,  subject to bankruptcy,  insolvency,  fraudulent conveyance and similar
laws affecting  creditors'  rights generally,  and general  principles of equity
(regardless of whether the  application  of such  principles are considered in a
proceeding in equity or at law).

        5. The Parent Guaranty has been duly authorized,  executed and delivered
by Parent Guarantor and constitutes the legal,  valid and binding  obligation of
Parent  Guarantor  enforceable  against Parent  Guarantor in accordance with the
terms  thereof,  subject  to  applicable  bankruptcy,   insolvency,   fraudulent
conveyance, moratorium or similar laws affecting creditors' rights generally and
to general  principles  of equity  (regardless  of whether such  principles  are
considered in a proceeding in equity or at law).

        6. The  Subsidiary  Guaranty  has been  duly  authorized,  executed  and
delivered by each Subsidiary Guarantor.

        7. The  issuance,  sale  and  delivery  of the  Certificates  under  the
circumstances  contemplated  by the Lease do not, under existing law require the
registration of the Certificates under the Securities Act of 1933, as amended or
the  qualification of the Trust Agreement under the Trust Indenture Act of 1939,
as amended.

        Our  opinions as to the matters  referred  to in  Paragraphs  1, 2 and 3
above  are  based  and  given  in  sole  reliance  upon  an  examination  of the
Certificate of Incorporation or Articles of  Incorporation,  as the case may be,
and  By-laws  of  Lessees,   Subsidiary  Guarantors  and  Parent  Guarantor  and
Certificates  of the  Secretary  of State of the  States  of  Delaware  and West
Virginia,  as the case may be. We believe  that the  opinion of  [_____________]
delivered to you on the date hereof is  satisfactory  in scope and form and that
you are justified in relying thereon.

        Our opinion is limited to the laws of the State of Illinois, the general
corporate  law of the States of West  Virginia and Delaware and the Federal laws
of the  United  States of  America  and we express no opinion on the laws of any
other jurisdiction.  We give no opinion whatsoever on the legal, valid,  binding
and enforceable nature of the Subsidiary Guaranty.
