                              failure for a period of thirty (30) days
                              following written notice to Covol of such
                              failure, unless Covol upon receipt of such
                              notice in good faith shall have promptly
                              commenced and thereafter shall continue
                              diligently to prosecute all action necessary to

                              bankruptcy or shall be adjudicated as a bankrupt
                              or insolvent, or shall file any petition or
                              answer seeking or acquiescing in any

                              debtors; or shall seek or consent to or
                              acquiesce in the appointment of any trustee,
                              receiver or liquidator of itself; or shall make
                              any assignment for the benefit of creditors or

                                                       9

                              generally as they become due.

                  (iv)        The entry by court of competent jurisdiction of
                              an order, judgment or decree approving a

                              federal or state law or regulation relating to
                              bankruptcy, insolvency or other relief for
                              debtors, which order, judgment or decree remains
                              unvacated and unstayed for an aggregate of sixty
                              (60) days (whether or not consecutive) from the
                              date of entry thereof; or the appointment of any
                              trustee, receiver or liquidator of Covol without
                              the consent or acquiescence of Covol, which
                              appointment shall remain unvacated and unstayed
                              for an aggregate of sixty (60) days (whether or
                              not consecutive).

         (b)      Remedies.  Upon the occurrence of any event of default, Parker
shall have the option,  in addition to any remedy or right given hereunder or by
law or equity, to do any one or more of the following

                  (i)         Terminate  this  Sublease,  in which  event  Covol
                              shall  immediately  surrender  possession  of  the
                              premises  to Parker  together  with all  rights of
                              Covol with respect to the premises.

                  (ii)        Re-enter and take possession of the premises
                              with or without having terminated this Sublease.

                  (iii)       Alter locks and other security devices of Covol
                              at or on the premises;

                  (iv)        File suit to collect any and all amounts
                              presently due and owing to Parker.

         If Parker  elects to repossess  the premises  without  terminating  the
Sublease,  the rent required to be paid by Covol to Parker thereafter during the
remainder  of the term  hereof  shall be due and  payable  each  month as herein
provided,  and Parker may bring action from time to time to collect such amounts
as have already accrued  without  waiting until  expiration of the current term,
provided that any net sums  received by Parker by reletting the premises  during
said period shall be applied  against the total  indebtedness of Covol to Parker
hereunder,  but in no event  shall  Covol be entitled to any excess of any rents
obtained by reletting  over and above the rent herein  reserved,  although Covol
shall receive credit therefor against rents as they accrue.


                                                       10





         (c)  Forbearance  No Waiver.  Any  forbearance  or failure of Parker to
enforce  its  rights  under this  Sublease  shall not be deemed a waiver of such
rights and shall not  constitute a waiver of its right to proceed  against Covol
for any act of default then existing or thereafter occurring.

                                                    SECTION XX

                                             Effect of Eminent Domain.

         (a)  Effect of Total  Condemnation.  In the event the  entire  premises
shall be  appropriated  or taken under the power of eminent domain by any public
or  quasi-public  authority,  this Sublease shall terminate and expire as of the
date of such taking,  and Parker and Covol shall  thereupon be released from any
liability  thereafter  accruing  hereunder,  except for Covol's  obligations  to
indemnify and hold harmless Parker and Owner.

         (b)  Effect of  Partial  Condemnation.  In the  event a portion  of the
premises  shall be so  appropriated  or taken and the  remainder of the premises
shall not be suitable for the use then being made of the  premises by Covol,  or
if the remainder of the premises is not one undivided parcel of property,  Covol
shall have the right to terminate this Sublease as of the date of such taking or
giving to Parker  written  notice of such  termination  within  ninety (90) days
after  Parker has  notified  Covol in writing that a portion of the premises has
been so  appropriated  or taken.  In the event of such partial  taking and Covol
does not so terminate this  Sublease,  then this Sublease shall continue in full
force and effect as to the part not taken.

         (c)  Condemnation  Award.  In the  event  of the  termination  of  this
Sublease  by reason of the total or partial  taking of the  premises  by eminent
domain, then in any such condemnation proceedings Parker and Covol shall be free
to make claim against the  condemning or taking  authority for the amount of any
damage done to them, respectively, as a result thereof.

                                                    SECTION XXI

                                               Permits and Licenses.

         Parker  agrees to take such steps as shall be  reasonably  necessary to
assign to Covol the benefit of Parker's  existing permits with respect to use of
navigable waterways  contiguous to the premises.  Covol shall be responsible for
obtaining and maintaining all other  necessary  permits,  licenses and approvals
required  in  connection  with  its use of the  premises.  Parker  shall  not be
responsible  for obtaining any such other  permits,  licenses or approvals,  but
shall execute such  applications  or other  documents as Covol shall  reasonably
request so long as Parker shall not incur any liability thereunder.




                                                       11





                                                   SECTION XXII

                                            Waste Disposal; Covenant to
                                      Comply with Environmental Requirements.

         (a) Covol shall  promptly  remove from the premises all waste  products
produced in connection with its use of the premises and all spoil resulting from
any dredging and waterway improvement.  Such waste products may be stored on the
premises,  in a safe and sanitary manner,  for a period not exceeding sixty (60)
days. The coals fines used by Tenant as feedstock for its coal processing  plant
will not be  considered a waste  product and may be  reasonably  stockpiled  for
operational purposes.

         (b)  Environmental   Covenant  and  Indemnity.   Without  limiting  the
generality of Paragraph (a) hereof,  Covol agrees to comply in all respects with
all laws,  rules and  regulations  pertaining  to  storage,  use or  disposal of
hazardous substances or wastes. In addition,  Covol agrees to indemnify,  defend
and hold harmless Parker,  the Owner and their respective  officers,  directors,
employees, agents, assignees,  sublessees and licensees from any liability which
may arise from or relate in any way,  directly or  indirectly,  to the handling,
use,  generation,  processing,  release,  discharge,  storage or disposal of any
hazardous or toxic substances, including, without limitation, petroleum products
or  byproducts,  any  flammable  explosives,  radioactive  materials,  hazardous
materials,  hazardous waste, asbestos,  PCB's,  phosphates,  lead or other heavy
metals,  chlorine,  radon gas, "hazardous  substance,"  "hazardous material," or
"hazardous waste," all as contemplated and governed by applicable federal, state
or local laws, rules and regulations pertaining to such matters.

         (c)  Notwithstanding  other  provisions  herein,  Tenant  will  not  be
responsible or liable for  contamination of the premises which occurred prior to
the  execution  of this  Lease.  Tenant  will  establish  a  baseline  for  such
contamination  by  taking  ground  water  and  other  samples  within 30 days of
execution  of this  Lease.  The samples  will then be  analyzed  and the reports
therefrom  will  establish the baseline for  allocation of liability  under this
Lease.  Tenant will furnish a copy of such fundings to the Landlord and Landlord
may independently verify Tenant's findings.

                                                   SECTION XXIII

                                             Miscellaneous Provisions.

         (a)      Time of the Essence.  The parties agree that time shall be  of
the essence as to the performance of each and every provision hereof.

         (b)      Notices.  Any and all notices by Parker to Covol, or by  Covol
to  Parker,  shall be in  writing  and shall be deemed to have been  given  when
personally  delivered  to the other party or when  deposited  in the U.S.  mail,
registered or certified,  return receipt requested,  addressed to the respective

conditions and undertakings in this Sublease  contained,  shall extend to and be
binding upon the heirs,  executors,  successors and assigns or Parker and Covol,
respectively,  but nothing  herein shall permit  sublease or assignment by Covol
without compliance with Section IX hereof.

         (d)  Holdover.  If Covol shall  continue in  possession of the premises
after the  expiration of the term of this  Sublease,  or any extension  thereof,

default or event of default under such Lease Agreement.

duplicate original counterparts as of the date first above written.
