        LUMP SUM CONTRACT PRICE             *

ARTICLE 4. PROGRESS PAYMENTS

        Payments made  pursuant to the Agreement for Limited  Notice to Proceed,
dated May 4, 2005 between OWNER and CONTRACTOR  shall suffice as advance payment
and be applied to this Contract.  All succeeding progress payments shall be made
in  accordance  with the  terms set forth in the  following  paragraphs  of this
Article.

        Prior to Contract signing,  CONTRACTOR shall submit a Schedule of Values

writing,  progress  payments  shall be paid. The Schedule of Values for Progress
Payments shall include  engineering,  equipment,  and construction  totaling the
Lump Sum  Contract  Price.  On or before  the tenth  (10th)  Day of each  month,
CONTRACTOR shall submit an itemized invoice for payment pursuant to the Schedule

OWNER.   CONTRACTOR  shall  substantiate   engineering   services,   procurement
commitments  and  equipment  and  materials-in-progress   with  such  additional
documentation as shall reasonably be requested by OWNER. CONTRARCTOR will retain
and make available for tax purposes supporting detail information related to the
invoice as  requested  by OWNER,  including  details of  engineering  and design

                                  Page 3 of 32


        OWNER  shall  make  payments  on  account  of this  Contract,  except as
otherwise provided herein, as follows:  On or before the tenth (10th) Day of the
following  month after  receipt of the invoice,  OWNER shall pay the  undisputed
amount of the invoice,  as per the Project  Progress  Schedule.  Provided,  that
OWNER  shall be  entitled  to  withhold  from the final  payment or  immediately
preceding  payments,  as necessary,  a sum, not to exceed  $3,000,000.  If OWNER
foresees that the final  payment will not equal this amount,  OWNER may withhold
from the immediately  preceding invoice or invoices,  as necessary to accumulate
this sum.  OWNER may retain  this sum for a period of time not to exceed  ninety
(90) Days after Mechanical Completion,  and may deduct from such sum any amounts
necessary  to  obtain  release  of  liens on the Work or  complete  other  items
required to be completed by CONTRACTOR  hereunder but which remain unreleased or
uncompleted after reasonable  notice to CONTRACTOR.  After expiration of such 90
Day period, OWNER will refund to CONTRACTOR any amounts remaining from such sum.

        Within ten (10) Days after OWNER receives  CONTRACTOR's  invoice,  OWNER
shall notify  CONTRACTOR  concerning any invoiced  amount that is in dispute and
the  contractual  basis  for such  dispute.  OWNER'S  payment  and  CONTRACTOR's
acceptance  of any payment  shall not be deemed to constitute a waiver by either
party of amounts that are then in dispute.  CONTRACTOR and OWNER shall use their
reasonable  efforts to resolve all disputed amounts as expeditiously as possible
in accordance with the provisions of Article 8.

        If an invoice is not  delivered by  CONTRACTOR  on or before the 10th of
the month,  payment may be withheld for an additional  thirty (30) Days for that
portion  of  the  invoice  which  is  not  in  compliance   with  the  invoicing
requirements  in this Article 4. OWNER shall in no event make payments in excess
of the  contract  value of  labor,  materials,  equipment,  services,  etc.,  in
progress, furnished or completed to date. CONTRACTOR agrees that monies received
for the  performance  of this  Contract  shall be used  primarily  for labor and
materials  entering  into Work under this  Contract and said monies shall not be
diverted to satisfy obligations of CONTRACTOR on other contracts.

        Upon receipt of the partial  payments,  CONTRACTOR  shall  furnish OWNER
with  such   partial   releases   and  waivers  of  lien  from  itself  and  its
subcontractors  and significant  suppliers as OWNER may reasonably  request from
time to time on labor and/or material and/or other claims.

        All invoices shall  reference  OWNER'S  Contract  Number and Item Number
____________ and be mailed to:

                               Riverside Cement Company
                               3500 Porsche Way, Suite 150

                               Attention: William O. Brown

        Payments made to CONTRACTOR by OWNER  hereunder  shall be made by an ACH
electronic payment in the following format, in order of preference:  CCD+ or CTX
or CTP format,  to the account of  CONTRACTOR  as specified  on the invoice.  If
undisputed  payments are not made as required by the Contract terms,  CONTRACTOR
may invoice  interest at the prime rate of  interest as  published  from time to
time in the Wall Street Journal plus one percent (1%) until paid.

ARTICLE 5.  SUBSTANTIAL COMPLETION AND MECHANICAL COMPLETION

5.1     Certificate of Substantial Completion.  Once all of the requirements for
Substantial  Completion have been satisfied CONTRACTOR shall so certify to OWNER
by submitting a Certificate of Substantial  Completion to OWNER, a copy of which
is  attached  hereto as an Exhibit to Section 4 of Exhibit A.  Within  seven (7)
Days following  receipt of such  Certificate of  Substantial  Completion,  OWNER
shall notify  CONTRACTOR by execution of this Certificate  whether OWNER concurs
that  CONTRACTOR  has met the  requirements  for  Substantial  Completion.  Such
certification  shall  not be  deemed  to  waive  any  rights  of  OWNER  against
CONTRACTOR   under  this  Contract.   Concurrent  with  such   certification  of
acceptance,  which  shall  be  evidenced  by  execution  of the  Certificate  of
Substantial  Completion by OWNER,  Substantial Completion will have occurred and
OWNER shall assume care,  custody,  and control of and shall  thereafter  assume
sole  responsibility  for risk of loss for that  portion  of the Work.  If OWNER
determines that CONTRACTOR has not met Substantial Completion,  then OWNER shall
deliver a written  notice to  CONTRACTOR  describing  in  reasonable  detail the
deficiencies  noted and corrective action  recommended.  Substantial  Completion
shall  not be deemed to have  occurred,  and  CONTRACTOR  shall be  required  to
perform the  remaining  requirements  for  Substantial  Completion  and submit a
revised  Certificate  of  Substantial  Completion.  Any dispute  regarding  such
certification  shall be resolved in  accordance  with the procedure set forth in
Article  8.  If,  following  the  initial  or  any  subsequent   Certificate  of
Substantial  Completion,  OWNER has not delivered to CONTRACTOR an acceptance or
rejection of such certificate as required herein, Substantial Completion will be
deemed to have occurred and the date of CONTRACTOR's most recent  Certificate of
Substantial  Completion shall be deemed the date that Substantial Completion was
actually achieved.

5.2     Certificate of Mechanical Completion.  Once CONTRACTOR has performed all
of the  requirements for Mechanical  Completion,  CONTRACTOR shall so certify to
OWNER by submitting a Certificate  of Mechanical  Completion to OWNER, a copy of
which is attached  hereto as an Exhibit to Section 4 of Exhibit A. Within  seven
(7) Days following receipt of such Certificate of Mechanical  Completion,  OWNER
shall notify  CONTRACTOR by execution of this Certificate  whether OWNER concurs
that  CONTRACTOR  has met  the  requirements  for  Mechanical  Completion.  Such
certification  shall  not be  deemed  to  waive  any  rights  of  OWNER  against
CONTRACTOR   under  this  Contract.   Concurrent  with  such   certification  of
acceptance,  which  shall  be  evidenced  by  execution  of the  Certificate  of
Mechanical  Completion by OWNER,  Mechanical  Completion  will have occurred and
OWNER shall assume care,  custody,  and control of and shall  thereafter  assume
sole  responsibility  for risk of loss for the Work.  If OWNER  determines  that
CONTRACTOR has not met Mechanical Completion, then OWNER shall deliver a written
notice to CONTRACTOR  describing in reasonable detail the deficiencies noted and
correction action recommended. Mechanical Completion shall not be deemed to have
occurred and CONTRACTOR shall be required to perform the remaining  requirements
for  Mechanical  Completion  and  submit a  revised  Certificate  of  Mechanical
Completion.  Any  dispute  regarding  such  certification  shall be  resolved in
accordance with the procedure set forth in Article 8. If,  following the initial
or any  re-issuance of the Certificate of Mechanical  Completion,  OWNER has not
delivered to CONTRACTOR an acceptance or rejection of such certification  within
seven (7) Days as required herein,  Mechanical Completion will be deemed to have
occurred and the date of  CONTRACTOR's  most recent  Certificate  of  Mechanical
Completion  shall be deemed the date that  Mechanical  Completion  was  actually
achieved.

                                  Page 5 of 32


        OWNER shall execute the Certificate of Mechanical  Completion,  provided
that each of the following conditions has been fulfilled:

        (a)     Said Work has been completed in all respects in accordance  with
        the Contract Documents;
        (b)     CONTRACTOR has performed all its obligations under this Contract
        (except  warranty and other  obligations  which, by their terms, are not
        then due); and
        (c)     CONTRACTOR  has submitted  reasonable  evidence in the form of a
        final release and waiver of lien from itself and its  subcontractors  to
        OWNER that  CONTRACTOR  and its  subcontractors  have paid all payrolls,
        material bills, and other indebtedness connected with said Work.

and  CONTRACTOR  shall do no Work  without  OWNER'S  approval  of  Drawings  and
Specifications, in accordance with Section 6.4.

        CONTRACTOR shall provide and pay for all materials, labor, water, tools,
equipment,  light,  transportation,  and  other  facilities  necessary  for  the
execution  and  completion  of Work as set out in Exhibit A, Scope of Work.  All
materials and equipment  incorporated into the Work shall be new, and CONTRACTOR
represents that all Work under the Contract shall be of a finished nature.

        CONTRACTOR  agrees to  prosecute  its Work as is  necessary to cause the
Work to be completed in accordance with the schedule described in Section 4.1 of
Exhibit A, Project Progress Schedule, attached hereto, subject to adjustments as
provided herein.

        CONTRACTOR  shall be fully  responsible for all necessary  expediting of

delays in its Work.  Defective  materials or materials  damaged in the course of
installation or test shall be replaced or repaired in a manner conforming to the

the manner  recommended by the  manufacturer of such equipment,  and to maintain
such  OEM  Equipment  as  recommended  by  the  manufacturer  until  Substantial
Completion.  In the event  CONTRACTOR  does not have necessary  installation  or

6.2     Prosecution  of the Work.  CONTRACTOR  agrees to  prosecute  its Work in

6.3     Construction  Drawings.  CONTRACTOR  shall furnish promptly to OWNER all
        -----------------------
drawings and  schedules  required in connection  with its Work,  but approval of
such drawings and schedules shall not relieve  CONTRACTOR of its  responsibility
of complying with the requirements of the Drawings and  Specifications of OWNER.
CONTRACTOR  shall take all field  measurements  necessary for its Work and shall
assume responsibility for their accuracy.

6.4     Approval of Drawings.  Detail, design and schematic drawings of the Work
        ---------------------
shall be submitted  electronically (via AMEC website) by CONTRACTOR to the OWNER
for approval  thereof.  CONTRACTOR,  upon  request  from OWNER,  shall submit to
OWNER,  for  review  only,  all  relevant  design  calculations.  One (1) set of
drawings  is to be  marked  by OWNER  as  "Approved",  "Approved  as  Noted"  or
"Disapproved as Noted" and returned to CONTRACTOR. Provided CONTRACTOR and OWNER
agree with  changes  made by OWNER in  drawings  marked  "Approval  as Noted" or
"Disapproved  as Noted" said  drawings  shall be  corrected  by  CONTRACTOR  and

modifications are outside the Scope of Work or Project Progress Schedule, and if
changes or modifications  are made after OWNER's written approval (which is only
deemed to be provided if CONTRACTOR  has complied with all  procedures set forth
in this Contract regarding change orders),  such changes or modifications  could
adjust  the Lump Sum  Contract  Price  (either up or down)  and/or  the  Project
Progress Schedule as provided in Section 6.13, Changes. CONTRACTOR shall utilize
the most reasonably expeditious means of mail or electronic transmittal delivery
to assure timely submittal of drawings to OWNER. The failure of OWNER to approve
or  disapprove  drawings  within seven (7) Days after  receipt  thereof shall be
construed as approval  thereof by OWNER.  Upon approval of such  drawings,  they
shall  become part of the  Contract  deliverables.  Approved  drawings  shall be
issued by CONTRACTOR and one (1) set of electronic drawings will be furnished to
OWNER.  Approval of drawings hereunder by OWNER shall not constitute a waiver or
release of any kind, and shall not relieve  CONTRACTOR of its  responsibility to
comply fully and completely with the Scope of Work, warranties,  representations
and all other commitments or responsibilities set forth in this Contract.

        CONTRACTOR  shall furnish to Owner one (1) electronic (via AMEC website)

pursuant to this  Contract,  to the extent  necessary  or helpful to perform the
duties for which such  third  party was  retained.  Provided,  further,  that no
confidentiality  restrictions  shall apply to information which becomes publicly

the safety of OWNER'S employees as well as CONTRACTOR'S employees.

        CONTRACTOR shall comply with MSHA  regulations.  Citations  arising as a
result of CONTRACTOR or its  Subcontractors  not following MSHA regulations will
be for CONTRACTOR to pay or defend.

        CONTRACTOR  shall  provide  safety  training  as  required  by MSHA  for
CONTRACTOR'S  employees  who  work on the  Plant  Site.  This  training  must be
completed  and written  confirmation  of such must be  furnished to OWNER before
Work  can  commence.  Training  will be  provided  by  CONTRACTOR  obtaining  an
MSHA-certified  instructor  permit and  providing  training  as required by MSHA

        Drawings and  Specifications  in  accordance  with this Contract and any
        other assistance that CONTRACTOR may reasonably require for carrying out
        the Work hereunder including prompt review and, if acceptable,  approval
        of all equipment  and  fabricated  items and vendor and  vendor-supplied
        equipment  in  accordance  with this  Contract,  and  prompt  and timely
        performance  of  all  OWNER  required   obligations;
        (j)     Commercially   reasonable  efforts  to  help  CONTRACTOR  obtain

        OWNER relating to the provision or failure to provide such concrete; and
        (k)     All of the items OWNER shall furnish in accordance  with
        Article 1.

6.11    CONTRACTOR'S  Representative.  The CONTRACTOR  shall employ a qualified,
        -----------------------------
competent  representative  who shall be in  attendance  at the site  during  the
progress of the Work and shall represent the CONTRACTOR.

6.12    Concealed Conditions.  Should concealed conditions be encountered in the
        ---------------------
performance  of the Work below the surface of the ground or should  concealed or
unknown conditions be at variance with the conditions indicated by the documents
provided by OWNER to CONTRACTOR  and referenced in the Basis of Price section of
the Scope of Work in Exhibit  A, then the Lump Sum  Contract  Price and  Project
Progress  Schedule  may be  equitably  adjusted by Change  Order as  hereinafter
defined in accordance with Section 6.13,  Changes.  Such varying  conditions may
include without  limitation  previously  unknown  subsurface and latent physical
conditions  at the  Jobsite,  archeological  finds  of  historical  or  cultural
significance,  protected or endangered  species of plants and animals,  or other
conditions  that  may  preclude  CONTRACTOR  from  proceeding  with the Work for
reasons of health,  safety,  or legal  restriction.  Without  waiving its rights
hereunder,  CONTRACTOR  agrees  to  notify  OWNER of such  conditions  promptly,
whereupon OWNER will promptly  investigate the same and issue appropriate orders
or instructions to CONTRACTOR.

6.13    Changes.  The right is reserved by OWNER to make changes in,  deviations
        --------
from, additions to, and omissions from the Work herein contracted,  and the Lump
Sum Contract Price and Project Progress Schedule shall be adjusted  accordingly.
Before proceeding with any change, deviation,  addition or omission,  CONTRACTOR
will first obtain written  authorization from OWNER, to be signed exclusively by
William O. Brown,  or such person as OWNER or he may  designate in writing.  Any
and all changes to the Scope of Work and the Lump Sum Contract  Price must first
be agreed to in writing by OWNER and CONTRACTOR.

                                  Page 10 of 32


        6.13.1  CONTRACTOR shall be entitled to adjustments,  in accordance with
        Section  6.13.2,  in the Lump Sum  Contract  Price and Project  Progress
        Schedule for the following events:

        (a)     Any part of the Work is  delayed by any act or failure to act by
        OWNER or third  parties  performing  Work for OWNER to the  extent  such
        action is the  responsibility  of OWNER as set forth in this Contract or
        by Force Majeure as provided in Section 6.17;
        (b)     CONTRACTOR'S   costs  are   increased  due  to  changes  in  any
        applicable laws,  codes or other  governmental  regulations,  or OWNER'S
        Safety  Procedures,  subsequent to the execution of this Contract,  or a
        substantial  change in the method of  imposition or  enforcement  of any
        applicable  laws, codes or regulations,  or any special  requirements of
        any governmental authority;
        (c)     CONTRACTOR'S   costs  are  increased  due  to  encountering  any
        concealed or unknown  conditions in  accordance  with Section 6.12 above
        unless  such  conditions  are  specified  by  this  Contract  to be  the
        responsibility of CONTRACTOR;
        (d)     CONTRACTOR'S  costs are  increased due to any variance in design
        conditions or other  information not otherwise  required or specified by
        this Contract, if any, provided by OWNER's  Representative;
        (e)     OWNER's  request for or approval of  performance of services not
        otherwise  required by this Contract in excess of CONTRACTOR's  standard
        work  day or  work  week  or  such  shorter  times  as are  provided  by
        applicable  collective bargaining agreements or on a holiday customarily
        observed by  CONTRACTOR  (including  an allowance for loss of efficiency
        due to overtime  work or shift  work);  or
        (f)     any and all other events which  entitle  CONTRACTOR  to a Change
        Order pursuant to this Contract.

        6.13.2  In connection  with any change,  addition or event  specified in
        this Section 6.13,  CONTRACTOR shall promptly submit in writing to OWNER
        pursuant to a mutually agreed upon procedure,  such proposed adjustments
        to the Lump Sum Contract Price  (including for G&A and fee * as a result
        of the change or  addition),  Project  Progress  Schedule,  and affected
        Contractor obligations, if any; and OWNER and CONTRACTOR shall negotiate
        in good faith regarding the amount of such adjustments and shall attempt
        in good faith to agree in writing as to such  adjustments.  The  parties
        agree that, so far as reasonably  possible,  no additional Work shall be
        performed  until either the amount of or nature of the  adjustment  with
        respect  thereto has been  mutually  agreed upon.  In no case,  however,
        shall  CONTRACTOR  perform any such  additional or different  Work until
        OWNER has authorized CONTRACTOR by Change Order to proceed therewith.

        In the event that OWNER and CONTRACTOR cannot agree on the adjustment to
        the Lump Sum Contract  Price,  Project  Progress  Schedule,  or affected
        Contractor  obligations  for a  Change  Order  to  which  CONTRACTOR  is
        entitled  pursuant to Section 6.13,  upon OWNER's  written  direction to
        CONTRACTOR,  CONTRACTOR  shall proceed with the  additional or different
        Work provided in the Change Order and OWNER shall pay to CONTRACTOR  all
        undisputed amounts and fifty percent (50%) of the disputed amounts while
        CONTRACTOR  is  continuing  performance  until the  dispute  is  finally
        resolved.

                                  Page 11 of 32


        In the event CONTRACTOR  contends that it is entitled to a Change Order,
        but OWNER  disagrees,  CONTRACTOR is under no obligation to proceed with
        such disputed Work. If however, OWNER issues CONTRACTOR a written Change
        Order for such Work,  CONTRACTOR  shall proceed with the disputed  Work,
        provided  in the  Change  Order and OWNER  shall pay to  CONTRACTOR  all
        undisputed amounts and fifty percent (50%) of the disputed amounts while
        CONTRACTOR  is  continuing  performance  until the  dispute  is  finally
        resolved.

        If any dispute is not resolved within thirty (30) Days of the submission
        in  writing  by  CONTRACTOR  to OWNER of such  proposed  adjustments  or
        entitlement  to a Change  Order,  CONTRACTOR  or OWNER may  submit  such
        dispute for  resolution  in  accordance  with Article 8,  Resolution  of
        Disputes. In the event the Work is delayed pending such resolution,  the
        Arbitrators  shall schedule the Arbitration to be completed with a final
        verdict not more than 90 Days after submission by either party.

        6.13.3  CONTRACTOR  shall use all  commercially  reasonable  efforts  to
        reschedule and reallocate the Work in a manner that minimizes the impact
        of any Change Order on the overall cost and schedule of the Project.

6.14    Protection of Work. It is mutually  agreed that  CONTRACTOR  will assume
        -------------------
responsibility  for  protection of materials and equipment  left on the Jobsite.
CONTRACTOR  shall use  reasonable  efforts  to  continuously  maintain  adequate
protection of all its Work from damage, such protection to include a watchperson
or  watchpersons  when  necessary,  and shall use reasonable  efforts to protect
OWNER'S  property  from injury or loss arising in  connection  with or resulting
from  CONTRACTOR'S  Work or materials or labor  necessary to perform the Work in
this  Contract.  CONTRACTOR  shall make good any such damage,  injury,  or loss,
except such as may be caused by the  negligent  act or omissions or  intentional
misconduct or gross negligence of agents or employees of OWNER.  CONTRACTOR will
be liable  for the  first  $10,000  of loss per  occurrence  to the Work  and/or
materials and equipment for which  CONTRACTOR is responsible  until  Substantial
Completion.  Except to the extent  CONTRACTOR is responsible  for loss or damage
pursuant to this  Section  6.14,  OWNER shall retain any and all risk of loss or
damage to the Work  (which  will be deemed for  purposes  of this  provision  to
include any goods CONTRACTOR or its  subcontractors  or suppliers may provide to
be installed). For loss or damage caused by all other causes and for any amounts
in excess of this per occurrence deductible,  OWNER agrees to look solely to the
proceeds of the  OWNER-furnished  insurance  described in Article 7 for recovery
for loss, and not seek recovery against CONTRACTOR or any subcontractor for such
loss.  CONTRACTOR  shall  take  all  necessary  precautions  for the  safety  of
CONTRACTOR'S  employees on the Work, and it shall designate a responsible member
of its  organization  on the  Work,  whose  duty  shall  be  the  prevention  of
accidents.  The name and position of any person so designated  shall be reported
to OWNER by  CONTRACTOR.  CONTRACTOR  shall  provide,  at its expense,  whatever
storage  sheds,  workshops  and offices  necessary  for the  performance  of the
Contract,  and shall remove the same upon the completion of the Work. CONTRACTOR
shall clean up and remove from the Jobsite as directed by OWNER, all rubbish and
debris.  In no manner  limiting  the  foregoing,  CONTRACTOR  shall  remove  all
construction  debris  from the  Jobsite at such times as will keep the Work area
safe and uncluttered and at any time promptly upon request of OWNER.

                                  Page 12 of 32


6.15    Access to and Inspection of Work.  CONTRACTOR shall  supervise,  inspect
        ---------------------------------
and be  responsible  for the  Work  and  shall  perform  the  Work  strictly  in
compliance with the Drawings and Specifications and all other provisions of this
Contract.   OWNER  and  any  mortgagee  of  OWNER,  if  any,  their  agents  and
representatives  shall, at all reasonable times, and after prior notification to
CONTRACTOR,  have the right of entry and free  access to inspect  all Work done,
labor performed and materials  furnished in and about the Jobsite,  compliant to
all CONTRACTOR and State or Federal Safety Requirements.

6.16    Correction of Work. At  CONTRACTOR'S  sole cost and expense,  CONTRACTOR
        -------------------
shall promptly correct, repair or replace (the parties to mutually agree whether
to correct,  repair or  replace)  any  defective  materials  and/or  workmanship
supplied  by  CONTRACTOR  to conform  to the  Contract  requirements.  Provided,
however,  if  inspection  reveals  that  any  correction  of Work  performed  by
CONTRACTOR was not due to defective  materials  and/or  workmanship  supplied by
CONTRACTOR,  such Work shall be treated as a Change in  accordance  with Section
6.13 above.

        Should  CONTRACTOR  refuse  or  neglect  to  proceed  at once  with  the
correction of rejected or defective materials and/or workmanship after receiving
notice to do so within the Warranty  Period,  it is agreed that OWNER shall have
the right and power to have the defects  remedied at the expense of  CONTRACTOR,
and  CONTRACTOR  agrees  to pay to OWNER  within  thirty  (30)  Days any and all
expense paid or directly  incurred by OWNER in remedying  such defects  together
with  interest  thereon at the prime rate of interest as published  from time to
time in the Wall Street  Journal  plus one percent  (1%) until paid.  CONTRACTOR
warrants  all  Work  performed  hereunder  against  defective  materials  and/or
workmanship, for a period of one (1) year from the date of Mechanical Completion
(the "Warranty Period").

6.17    Delays and  Extension of Time.  If  CONTRACTOR is delayed at any time in
        ------------------------------
the progress of the Work,  unless otherwise  permitted by this Contract,  by (i)
any act or  neglect  of OWNER,  or any  employee  of OWNER,  or by such act of a
separate  contractor  or agent  employed  by OWNER,  or (ii) Force  Majeure  (as
defined in Article 14), then the Project Progress  Schedule shall be extended as
provided in Section  6.13. In addition to such  extension of time,  there may be
other  adjustments in accordance with Section 6.13.  CONTRACTOR shall give OWNER
notice of any delay affecting the Work as soon as possible but in no event later
than five (5) Days after receipt of knowledge of such delay. Notwithstanding the
foregoing,  CONTRACTOR  shall  not be  entitled  to any  extension  of  time  or
increased  payments because of any delays occasioned by inclement or unfavorable
weather  normally  experienced  in the  geographic  area of the  Plant  Site (as
reported  by the  National  Weather  Service or a similar  agency) or any delays
occasioned  by  labor  disputes  of  employees  of  CONTRACTOR  or  any  of  its
subcontractors at the Jobsite.  OWNER shall not be liable to CONTRACTOR  because
of any such delays caused by labor disputes. If one or more Force Majeure events
causes  CONTRACTOR  to incur  costs in  excess  of  $200,000  in the  aggregate,
CONTRACTOR  shall be entitled to a Change Order pursuant to Section 6.13 for its
reasonable  out-of-pocket  costs actually and necessarily  incurred in excess of
$200,000 as a result of such Force Majeure event(s),  including  demobilization,
remobilization,  insurance,  standby and escalation costs. Such Change Order may
provide  that  CONTRACTOR  may add such costs to invoices  provided  pursuant to
Article  4  and  CONTRACTOR  shall  provide  such  supporting   information  and
documentation as OWNER may reasonably request.  OWNER shall pay such invoices as
provided in Article 4. In the event of a Force Majeure delay that  continues for
a period of more than sixty (60) Days, and OWNER and CONTRACTOR fail to agree to
such a Change Order before  expiration of such 60 Day period,  CONTRACTOR  shall
have the right to terminate  this  Contract upon at least thirty (30) Days prior
written notice to OWNER and OWNER shall have no liability to CONTRACTOR for lost
profits or any other costs related to items which are not actually  delivered to
OWNER prior to CONTRACTOR'S cancellation.

                                  Page 13 of 32


6.18    Suspension  of  Work.   OWNER  shall  have  the  right  to  suspend  the
        ---------------------
performance of the Work at anytime by giving twenty-four (24) hours prior notice
in writing of such action plus such  reasonable  time as may be required for the
suspension of the Work so as to beneficially conserve what Work has been done or
is actually in progress  for future use. No prior  notice in writing is required
if  suspension  is  necessary  as  a  result  of  CONTRACTOR   violating  safety
procedures.

        Suspension of the Work shall be made without  prejudice to the claims of
either party in respect of any antecedent breach of the terms of this Contract.

        CONTRACTOR  shall,  during the period of suspension,  use all reasonable
efforts  to  utilize  its  personnel  in such a manner as to  minimize  the cost
associated  with the  suspension.  Upon  receipt  of any  notice of  suspension,
CONTRACTOR shall, unless the notice requires otherwise:

        (a)     Immediately  discontinue  the  performance  of the  Work  to the
        extent  specified in the notice;
        (b)     Take no further action relative to  subcontractors  or suppliers
        with respect to suspended Work other than to the extent  required in the
        notice;
        (c)     Promptly make every reasonable  effort to obtain suspension upon
        terms  satisfactory  to the  OWNER  of  all  subcontracts  and  purchase
        agreements to the extent they relate to portions of the Work  suspended;
        and
        (d)     Upon receipt of notice to resume the suspended Work, promptly as
        practicable  resume the  suspended  Work to the extent  required  in the
        notice.

        As compensation to CONTRACTOR for any  suspension,  CONTRACTOR  shall be
reimbursed  for all  reasonable  costs  associated  with  the  mobilization  and
demobilization of CONTRACTOR and its  subcontractors and all reasonable costs in
bringing the Work to an orderly state of suspension, as well as all cancellation
costs and any expenses  reasonably  incurred,  including  escalation  costs. Any
suspension or Work stoppage due to CONTRACTOR's or CONTRACTOR's  subcontractors'
or agents' safety  violations  shall be at  CONTRACTOR'S  expense.  In addition,
standby costs incurred by CONTRACTOR during the period of suspension (except for
safety violations) incurred in keeping its organization committed to the Work in
a standby status shall be paid by OWNER on a reimbursable  basis.  These and any
further  adjustments to the Lump Sum Contract Price or Project Progress Schedule
shall be made in  accordance  with  Section  6.13,  Changes.  In the  event of a
suspension that continues for a period of more than sixty (60) Days,  CONTRACTOR
shall have the right to terminate this Contract in accordance with Section 6.20.

        In the event any  undisputed  amount  required to be paid or advanced to
CONTRACTOR by OWNER under this Contract is not paid or advanced to CONTRACTOR by
OWNER as required,  CONTRACTOR, by giving seven (7) Days written notice, may, at
its option, suspend the Work in whole or in part and/or terminate this Contract.
Subject to its rights under Section 6.20,  Right to Terminate  Contract,  if the
Work is suspended and not terminated, CONTRACTOR shall resume performance of the
suspended  Work as promptly  as  practicable  after OWNER makes full  payment or
advancement  to  CONTRACTOR  of such  unpaid  amount.  During  such  suspension,
CONTRACTOR  shall be entitled to compensation  pursuant to the provision of this
Section.  In the event of termination,  CONTRACTOR  shall be entitled to damages
resulting  from such  termination,  as  otherwise  limited or  required  by this
Contract.

                                  Page 14 of 32


6.19    OWNER'S Right to Do Work. If CONTRACTOR  should neglect to prosecute any
        -------------------------
substantive  portion of the Work properly,  OWNER, after five business (5) days'
written  notice  to  CONTRACTOR  and  CONTRACTOR  fails  to  promptly   initiate
corrective action,  may, without prejudice to any other remedy it may have, make
good such deficiencies and may deduct the cost thereof from the payments then or
thereafter due CONTRACTOR, and if such expenditures,  together with said losses,
damages  and extra  expenses,  exceed the  amount  otherwise  due to  CONTRACTOR
hereunder,  CONTRACTOR  agrees to pay to OWNER within  thirty (30) Days the full
amount of such  excess,  together  with  interest  thereon  at the prime rate of
interest  as  published  from time to time in the Wall Street  Journal  plus one
percent (1%) until paid.

6.20    Right  to  Terminate  Contract  If  either  Party  shall be  adjudged  a
        ------------------------------
bankrupt,  or if a Party should make a general assignment for the benefit of its
creditors, or if a receiver should be appointed on account of its insolvency, or
if it should  persistently or repeatedly  refuse or should fail, except in cases
for which  extension  of time is provided,  to supply  enough  properly  skilled
workmen or proper materials,  or if it should fail to make prompt payment to the
other Party,  subcontractors or for material or labor, or persistently disregard
laws,  regulations or  ordinances,  or otherwise be guilty of a violation of any
substantive  provision of this Contract,  then the non-defaulting  Party, in the
event that the defaulting Party does not promptly  initiate  corrective  action,
may,  without  prejudice  to any other  right or remedy  and  after  giving  the
defaulting Party and its surety, if any, ten (10) Days written notice, terminate
this  Contract,  and OWNER may  finish the Work by  whatever  method it may deem
expedient. In case of such cancellation,  the rights of the non-defaulting Party
shall be the same as if the defaulting Party had failed to perform this Contract
in whole or in part.

6.21    Taxes. Subject to Article 7, CONTRACTOR agrees to and does hereby accept
        ------
full and  exclusive  liability  for the payment of, and agrees to indemnify  and
hold  harmless  OWNER  from  claims,  damage,  loss and  expenses  arising  from
CONTRACTOR'S  failure  to  pay  for  unemployment  insurance  and/or  retirement
benefit, pensions or annuities now or hereafter imposed by the Government of the
United States and/or by the Government of any state of the United States,  which
are  measured  by the wages,  salaries  or other  remunerations  paid to persons
employed by CONTRACTOR on Work performed under the terms of this Contract.

        CONTRACTOR  assumes the liability of paying California Sales and Use Tax
to its suppliers or the appropriate  taxing authorities for all its purchases of
permanent materials and fixtures, consumable supplies, small tools, construction
machinery,  equipment  rental used to perform the  Contract and taxes on profits
(if any).  CONTRACTOR's Lump Sum Price includes  California Sales and Use Tax on
the CONTRACTOR's  purchases of (a) self-constructed  fixtures, (b) machinery and
equipment, and (c) permanent materials furnished under the Contract, if any.

                                 Page 15 of 32


        Any  additions  or  reductions  of charges to the OWNER will be lump sum
Change Orders and will be treated,  for sales and use tax purposes,  in the same
manner as under the original Contract.

        All ad  valorem  taxes  levied  by any  jurisdiction  in San  Bernardino
County,  California  on  or  charged  against  the  real  or  personal  property
constituting   the  materials  to  be   incorporated   into  the  Work  are  the
responsibility  of OWNER.  All ad valorem  taxes  levied on or  charged  against
personal  property  consumable  supplies,   tools,  construction  machinery  and
equipment   used  to  perform  the  Contract   owned  by   CONTRACTOR,   or  its
subcontractors,  are the  responsibility  of CONTRACTOR  or its  subcontractors,
respectively.

6.22    Subcontractor. CONTRACTOR shall not assign nor subcontract this Contract
        --------------
or any part thereof or any interest  therein without first obtaining the written
consent of OWNER. Such approval shall not be unreasonably  withheld.  CONTRACTOR
shall  be  fully  responsible  to  OWNER  for  the  acts  and  omissions  of its
subcontractors and of persons either directly or indirectly  employed by them as
it is for the acts and omissions of persons directly employed by it.

6.23    Federal Labor Compliance.  Neither  CONTRACTOR nor OWNER will unlawfully
        -------------------------
discriminate  against any employee or applicant for  employment  because of age,
race, color, religion, sex, or national origin and shall comply with all Federal
and California Laws.

        CONTRACTOR  will comply with all provisions of Executive  Order 11246 of
September 24, 1965,  and of the rules,  regulations  and relevant  orders of the
Secretary of Labor.

6.24    Scheduling. A detailed Project Progress Schedule indicating the state of
        -----------
Work is attached hereto as Section 4.1 of Exhibit A and hereby incorporated into
this Contract.  Such Project Progress Schedule may be modified by the CONTRACTOR
from time to time to reflect changes in the Work or the conditions affecting the
Work.  CONTRACTOR  shall notify OWNER of such changes  within five Days from the
time changes are known to  CONTRACTOR.  If these changes  affect the cost or are
likely to change the date of  Mechanical  Completion  the  change  must be first
approved in writing by OWNER's Representative and otherwise strictly comply with

                                  Page 16 of 32


6.27    Warranty. CONTRACTOR warrants to OWNER that all the Work as set forth in
        ---------
this  Contract will be free from defects in material and  workmanship,  has been
properly  installed  pursuant  to  this  Contract  and  applicable  manufacturer
specifications,  and will otherwise comply with the specifications  described in
this  Contract.  This  Warranty  shall  extend  for one (1)  year  from  date of
Mechanical Completion. In addition, CONTRACTOR warrants to OWNER that:

        6.27.1  The Work when completed will be free from defects in design that
would fall below the standard of care required of professional engineers;

        6.27.2  The Work when completed will be free from defects in workmanship
and materials that would fall below a good and workmanlike standard;

        6.27.3  Subject  to  Section  6.13,   the  Work  will  be  designed  and
constructed in compliance  with all applicable  laws,  regulations  and codes in
effect as of the effective date of the Contract;

        6.27.4  All machinery,  equipment,  facilities,  foundations (other than

construction  and  fabrication  practices  which  are in  accordance  with  good
industry practice.

CONTRACTOR  in its  Scope  of Work  under  the  Contract  will  give  sufficient
information and instructions to OWNER for the repair,  maintenance and operation
of CONTRACTOR's Work,  including any information and instructions that have been
provided to CONTRACTOR by the OEM (the "Operation and Maintenance Manuals").

        6.27.6  All equipment and supplies are installed in full compliance with
applicable OEM, OWNER, and Contract specifications.

6.28    Liability For Breach Of Warranty;  Limit of Liability. If any failure to
        ------------------------------------------------------
comply with CONTRACTOR'S  aforesaid warranty appears within the Warranty Period,
OWNER shall notify  CONTRACTOR of such failure,  and CONTRACTOR shall remedy any
such failure by  correcting,  repairing,  or replacing  (the parties to mutually
agree whether to correct,  repair or replace) such machinery,  equipment  and/or
services  within such time as shall be designated by OWNER.  EXCEPT AS STATED IN
THIS  CONTRACT  AND  EXCEPT  AS TO  TITLE,  THERE  ARE NO  OTHER  GUARANTEES  OR
WARRANTIES, INCLUDING OF HABITABILITY,  MERCHANTABILITY, FITNESS, PERFORMANCE OR
OTHERWISE,  WHETHER ORAL, EXPRESS, IMPLIED,  STATUTORY OR ARISING FROM COURSE OF
DEALING  OR  TRADE  USAGE.   CONTRACTOR'S  obligations  for  warranty  shall  be
enforceable  provided  that OWNER  maintains  and operates the  equipment  under
normal conditions with competent personnel and in accordance with the Operations
and Maintenance Manuals provided by CONTRACTOR. CONTRACTOR does not warrant Work
from ordinary wear, corrosion,  erosion,  chemical or abrasive action, excessive
heat,  improper  lubricating oil or application outside the design limitation of
the Work.  The  obligations  contained  in  Sections  6.27 and 6.28  govern  and
supersede  any other terms in this  Contract  which  address  warranties  or the
quality  of the Work  after  Mechanical  Completion  and are  CONTRACTOR'S  sole
warranty and guarantee  obligations and OWNER'S exclusive  remedies with respect
to defects in the Work after  Mechanical  Completion.  All of the warranties and
other  obligations  of  CONTRACTOR  under  Sections  6.27 and 6.28 relate to the
Warranty Period and CONTRACTOR shall not be obligated to correct,  or to pay for
the cost of correcting,  defects or deficiencies for which  CONTRACTOR  receives
notice after the expiration of the Warranty Period.

                                  Page 17 of 32


CONTRACTOR  shall  obtain  from  all  vendors  from  which  CONTRACTOR  procures
materials  and  equipment,  warranties  with  respect to such  equipment  as are
reasonably  available.  Such warranties shall obligate the respective vendors to
repair or replace  nonconforming or defective materials and equipment.  All such
warranties  shall be  assigned  to OWNER  upon  expiration  of the  CONTRACTOR's
Warranty  Period.  During the  CONTRACTOR'S  Warranty  Period,  CONTRACTOR shall
assume all  responsibility  at its expense for  administering and enforcing such
vendor  warranties and OWNER may rely upon and deal with CONTRACTOR with respect
to such warranties.  The warranties  specified in Section 6.27 above shall apply
to all portions of the Work provided by  subsidiaries  and vendors of CONTRACTOR
in addition to such portions provided by CONTRACTOR.  Unless otherwise  mutually
agreed by the  parties,  the  refractory  warranty  period will be that which is
provided by the manufacturer.

6.29    Patents.  Unless otherwise agreed in writing,  and subject to Article 7,
        --------
CONTRACTOR  shall defend at its expense,  indemnify  Indemnitees  (as defined in
Section 7.1.1), and pay cost and damages awarded in any suit brought against any
Indemnitee  based on the use or sale of  machinery,  equipment  and/or  services
furnished  hereunder  constituting  infringement  of a validly  existing  United
States  or  foreign  patent,  copyright,   trademark,   trade  secret  or  other
intellectual  property  right.  OWNER may,  at its  option,  participate  in the
defense,  compromise, or settlement of such claim provided that OWNER shall bear
the  cost  and  expenses  related  to such  participation.  In the  alternative,
CONTRACTOR,  at CONTRACTOR'S sole option, may fulfill its obligations under this
Section 6.29 by procuring for OWNER, as  appropriate,  the right to make, use or
sell  the  invention  or  matter  protected  by  the  aforementioned   infringed
intellectual  property right,  or by assisting OWNER in designing  modifications
necessary  to  eliminate   any  claim  of   infringement.   Any  cost  for  such
modifications shall be CONTRACTOR'S responsibility.

OWNER shall defend at its expense, indemnify the Indemnified Parties (as defined
in Section 7.1.6), and pay cost and damages awarded in any suit based on alleged
infringement of a patent, copyright or trademark brought against any Indemnified
Party  and  based on the use or sale of  machinery,  equipment  and/or  services
falling outside the CONTRACTOR's Scope of Work,  including,  without limitation,
the OEM.

6.31    CONTRACTOR'S Liability.
        -----------------------

        6.31.1  CONTRACTOR'S  AGGREGATE MAXIMUM LIABILITY (EXCLUSIVE OF PROCEEDS
OF INSURANCE PROVIDED BY OWNER PURSUANT TO ARTICLE 7) FOR LOSS OR DAMAGE ARISING
UNDER, RESULTING FROM OR CONNECTED WITH THIS CONTRACT OR FROM THE PERFORMANCE OR
BREACH OF ANY OBLIGATION IMPOSED  HEREUNDER,  WHETHER SUCH LIABILITY ARISES FROM
BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE),  DELAYED COMPLETION,  WARRANTY,
INDEMNITY,  STRICT LIABILITY OR OTHERWISE, UNLESS OTHERWISE LIMITED BY THE TERMS
HEREOF,  SHALL BE LIMITED TO TEN  PERCENT  (10%) OF THE TOTAL LUMP SUM  CONTRACT
PRICE,  WHETHER SUCH SUM IS EXPENDED IN REPAIR,  REPLACEMENT,  OTHER  CORRECTIVE
ACTION,  LIQUIDATED  DAMAGES,  IF ANY, OR DELAY DAMAGES,  REFUND OF THE CONTRACT
PRICE OR ANY SUCH REMEDY AS MAY BE PROVIDED.

        6.31.2  Except as it may be more narrowly limited by any other provision
of this Contract,  the liability of CONTRACTOR,  its subcontractors,  vendors or
agents, or their employees,  officers,  directors and shareholders (collectively
referred  to in this  section as  "CONTRACTOR")  to OWNER,  OWNER'S  affiliates,
insurers, or their employees, officers, directors and shareholders, or any third
parties  referred to below in Section 6.31.3  (collectively  referred to in this
section as  "OWNER")  for loss of or damage to  property  (other  than the Work)
shall be limited to: 1) the extent such loss or damage is caused by CONTRACTOR'S
negligence;  and 2) the lesser of: (i) the deductible under OWNER'S insurance or
(ii) $250,000 in the aggregate.

        6.31.3  OWNER  represents that it is (i) the sole owner of the Work, the
land   constituting   the  site  of  the  OWNER'S  plant  and  facilities  where
CONTRACTOR'S  Work will be  performed,  and any  inventory  or other  personalty
stored thereon  (collectively  "Property"),  or (ii) authorized to bind and does
bind (or will bind prior to the  occurrence  of any loss or damage  thereto) all
persons or entities  currently  having,  or acquiring in the future any legal or
equitable  interest  in or right to occupy  the  Property,  to the  indemnities,
releases and limitations of liability set forth in this Contract. If OWNER fails
to bind to this limitation any third party having, or hereafter  acquiring,  any
interest in the Property, OWNER agrees to indemnify,  defend and hold CONTRACTOR
harmless  from and  against  such  liability  to the extent  that it would cause
CONTRACTOR'S  total liability to exceed the limit of liability stated in Section
6.31.

        6.31.4  This  limitation  of  liability  and  indemnity  applies  to all
liability  arising from the CONTRACTOR'S  activities and obligations  related to
the Contract,  and any separate agreement with a third party to perform services
for OWNER'S  benefit on OWNER'S  Property,  as defined above,  including but not
limited to, duty  arising in contract,  warranty,  indemnity,  statute,  tort or
other theory of liability  (WHETHER SUCH  OCCURRENCE  ARISES OUT OF CONTRACTOR'S
SOLE OR CONCURRENT NEGLIGENCE OR BREACH OF ANY STANDARD OF STRICT LIABILITY).

        6.31.5  CONTRACTOR'S  liabilities are limited as set forth herein and it
is  expressly  agreed  that this  Contract  sets  forth  the sole and  exclusive
remedies  available to OWNER.  To the fullest extent  permitted by law,  neither
CONTRACTOR,  its  subcontractors  or  affiliates  nor  OWNER  shall,  under  any
circumstances,  be  liable  to the  other  for  special,  indirect,  incidental,
punitive, exemplary, or consequential damages, including but not limited to loss
of use of Plant Site, Jobsite, Work, or other property, loss of savings, loss of
use of capital or goodwill, product or business interruption,  increased cost of
capital, financing or other carrying charges, rental charges, or increased costs
of  operations,  maintenance  of staffing  needs,  loss of profits,  anticipated
revenue,  interest, loss of use of equipment,  loss by reason of plant shutdown,
non-operation,  additional  usage  of fuel or  utilities,  or other  such  claim
arising from any cause  whatsoever,  whether or not foreseeable,  and WHETHER OR
NOT SUCH  LOSS OR  DAMAGE  IS  BASED  IN  CONTRACT,  WARRANTY,  TORT  (INCLUDING
NEGLIGENCE),  STRICT LIABILITY,  INDEMNITY, OR OTHERWISE,  and each party hereby
releases the other party, and their respective agents and employees of each from
any and all such liability.  Notwithstanding  the foregoing,  this Section shall
not be deemed to limit any indemnification  obligation due from one party to the
other  resulting from third party claims for bodily injury or death or for third
party claims for  consequential  damages relating to patent  infringement to the
extent provided for elsewhere in this Contract, nor shall this Section be deemed
to limit  CONTRACTOR's  right to payment of the Lump Sum  Contract  Price to the
extent due pursuant to the terms hereof, as such amount may be amended by Change
Order.

                                  Page 19 of 32


        6.31.6  All  disclaimers,  limitations  and  exclusions  of liability to
which CONTRACTOR is entitled under this Contract, including without limiting the
generality of the foregoing,  limitations with respect to consequential damages,
liability and aggregate liability,  warranty and other damages shall survive the
termination  or completion of this Contract and shall inure to, and be available
as a defense by, the CONTRACTOR's affiliates,  subsidiaries,  subcontractors and
suppliers of any tier, and their respective officers,  directors,  shareholders,
agents and employees,  and CONTRACTOR  shall be deemed the agent of such persons
for the purpose of this section.

6.32    CONTRACTOR'S Insolvency.  If CONTRACTOR is adjudged a bankrupt, or makes
        ------------------------
a general  assignment  for the  benefit of its  creditors,  or if a receiver  of
CONTRACTOR'S assets is appointed because of CONTRACTOR'S insolvency or inability
to pay its debts, or if OWNER  otherwise has reasonable  grounds to believe that
CONTRACTOR'S  financial  stability  has become  impaired,  OWNER  shall have the
option of  terminating  this Contract by giving written notice of termination to
CONTRACTOR,  and such  termination  shall have the same effect as a  termination
under Section 6.20 of this Contract.

6.33    Failure  To Insist  Upon  Strict  Performance.  No  failure  by OWNER or
        ----------------------------------------------
CONTRACTOR  to  insist  upon  strict  performance  under  this  Contract  in any
particular  instance shall constitute a waiver of OWNER'S or CONTRACTOR's right,
as applicable, to insist upon strict performance in all other instances, whether
the same or different provisions of this Contract are involved.

6.34    Assignment.  This Contract and all  provisions  thereof shall be binding
        -----------
upon the respective  successors  and assigns of CONTRACTOR and OWNER,  provided,
however,  that  neither  party  shall  assign  this  Contract  or any  right  or
obligation thereunder without first obtaining the written consent thereto of the
other party. Such consent shall not be unreasonably withheld.

6.35    Entire  Agreement:  Modification  This  Contract  sets  forth the entire
        --------------------------------
agreement  and  understanding  between  the parties  hereto with  respect to the
subject  matter  hereof,  and no  attempted  amendment or  modification  of this
Contract  shall have any effect unless same is in writing and signed by the duly
authorized representatives of both parties hereto.

6.36    Third Party Beneficiaries.  The provisions of this Contract are intended
        --------------------------
for the sole  benefit  of OWNER and  CONTRACTOR  and  there  are no third  party
beneficiaries hereof except as provided in Section 6.31.

6.37    Severability.  The  invalidity  or  unenforceability  of any  portion or
        -------------
provision of this Contract shall in no way affect the validity or enforceability
of any other portion or provision hereof.  Any invalid or unenforceable  portion
or provision  shall be deemed  severed from this Contract and the balance of the
Contract shall be construed and enforced as if the Contract did not contain such
invalid or  unenforceable  portion or provision.  If any such  provision of this
Contract is so declared  invalid,  the Parties shall promptly  negotiate in good
faith new provisions to eliminate  such  invalidity and to restore this Contract
as near as possible to its original intent and effect.

6.38    No  Fiduciary  Duty.  Nothing in this  Contract  shall be  construed  as
        --------------------
creating a fiduciary duty between CONTRACTOR and OWNER, and the existence of any
such fiduciary duty between the Parties is hereby expressly disclaimed.

        7.1.1   To  the  fullest  extent  permitted  by  law,  CONTRACTOR  shall

including  if  necessary  any  cleanup  or  remediation  activities,  and  shall
indemnify  and hold  harmless  the  Indemnitees  from  and  against  any  Claims

or  suppliers  (excluding  Indemnitees)  only,  except to the  extent  caused by
negligence  or  willful  misconduct  on the part of the  applicable  Indemnitee.
Provided, however OWNER agrees that if it provides CONTRACTOR with any Hazardous
Materials  specifically  for  CONTRACTOR's  use in performance of the Work, such
Hazardous  Materials shall be identified on the packaging  thereof or OWNER will
identify  such  Hazardous  Materials in writing  when  provided,  including  any
applicable MSDS sheets.

        7.1.5   CONTRACTOR may temporarily  interrupt its Work and will promptly
inform  OWNER if it  reasonably  believes  there is undue  risk of  exposure  to
Hazardous Substances.  CONTRACTOR will cooperate with OWNER to determine when it
and others  under its control  may safely  resume  Work.  If  CONTRACTOR  is not
responsible  for,  and did not  cause the risk of  exposure  to,  the  Hazardous
Materials that caused the interruption in the Work,  CONTRACTOR will be entitled
to a Change  Order in  accordance  with Section  6.13,  of the Lump Sum Contract
Price and Project Progress  Schedule in connection with interruption of Work due
to Hazardous Substances.

        7.1.6   OWNER shall be fully  responsible  for all Hazardous  Substances
existing at the Jobsite as of the date of execution of the Contract. OWNER shall
indemnify, defend and hold harmless CONTRACTOR and its subcontractors, and their
officers, directors,  employees and agents ("Indemnified Party" for this Section
7.1.6), from and against any Claims resulting from an encounter with or exposure
to Hazardous  Materials or resulting from such Indemnified  Party's being deemed
an owner or operator of the Jobsite,  or a  generator,  storer,  transporter  or
treater  of  Hazardous  Materials  existing  at the  Jobsite  as-of  the date of
execution  of the  Contract,  for  purposes of any laws and permits  relating to
Hazardous  Materials or any  investigatory or remedial actions by any government
authorities having  jurisdiction over the Jobsite;  provided,  however that this
indemnity  shall  not  apply to the  extent of the sole  negligence  or  willful
misconduct  of an  Indemnified  Party  or  violation  of  applicable  of laws or
regulations by an Indemnified Party.  Without  limitation,  such indemnity shall
include  any  liability  of  the  Indemnified   Party  under  the  Comprehensive
Environmental  Response  Compensation  and  Liability  Act  (including  the SARA
amendments  thereto),  and any liability of the Indemnified Party resulting from
actions by any state or local agency.

        7.1.7   If any claim of Lien,  stop notice,  equitable lien or any other
demand for payment or security, including claims or demand upon surety bonds for
any of the Work, is made or filed with OWNER, OWNER'S property or the Jobsite by
any person claiming that CONTRACTOR, subcontractor, or any other person claiming
under any of them  (other  than  OWNER) had failed to  perform  its  contractual
obligations or to make payment for any obligation  incurred for or in connection
with the Work,  then OWNER,  subject to OWNER  having paid  CONTRACTOR  for such
amounts,  shall have the right to retain from any payment then due or thereafter
to become due CONTRACTOR or to be reimbursed by CONTRACTOR an amount  sufficient
to remedy  any such  nonpayment  (including  reasonably  and  actually  incurred
attorneys' and consultants' fees) sustained or incurred in connection therewith.
Upon mutual  agreement  of the parties,  CONTRACTOR  may furnish a bond or other
security  to  indemnify  OWNER  against  lien  claims  of   subcontractors   and
materialmen in order to receive payment from OWNER.

to  earthquake  (including  sinkhole)  and  flood,  which  earthquake  and flood
sublimits  shall  be  no  less  than  the  minimum  sublimits  for  such  losses

the industry for the size and scope of the Work. CONTRACTOR shall bear the first
$10,000 of the deductible amount (other than deductible amounts related to flood
or earthquake  coverage,  which OWNER shall be obliged to pay), with no increase
in the Lump Sum Contract Price.

any  wrongful  removal of any  property  of a named  insured  or any  additional

7.4     Requirements for All Insurance
        ------------------------------

        CONTRACTOR  shall cause the insurance to be obtained  under Section 7.2,
and OWNER shall cause the insurance it obtains under Section 7.3, to satisfy the
following provisions and requirements.

        7.4.1   Notwithstanding  limitations  of liability  under  Section 6.31,
OWNER  and  CONTRACTOR   waive  all  rights  against  (i)  each  other  and  the
subcontractors,  agents and  employees of each other,  and (ii)  subcontractors,
agents and  employees,  for damage  caused by fire or other  peril to the extent
covered  and paid by  property  insurance  obtained  by OWNER  pursuant  to this
Article 7 or by any other property insurance applicable to the Work, except such
rights as each may have to proceeds of such  insurance held by OWNER as trustee.
The  insurance  policies  obtained  by OWNER  pursuant  to Section  7.3 shall be
endorsed to include a waiver of  subrogation  in favor of Indemnitees as well as
CONTRACTOR  and its  subcontractors,  and the  insurance  policies  obtained  by
CONTRACTOR and its  subcontractors  pursuant to Section 7.2 shall be endorsed to
include a waiver of subrogation  in favor of  Indemnitees.  In addition,  to the
extent such  policy(ies) to be provided by OWNER have a deductible  greater than
$10,000,  OWNER shall waive all rights of recovery against CONTRACTOR for events
covered by Section 6.14 for any such deductible losses in excess of CONTRACTOR's
$10,000 deductible.

        7.4.2   All insurance  required by this Contract shall be from insurance
companies  authorized  to  transact  that  class of  insurance  in the  State of
California  or an approved not admitted  carrier and having a minimum  rating of
(or equivalent  to) A-VIIl by A.M. Best & Company or as otherwise  acceptable to
both  CONTRACTOR  and OWNER.  The  required  certificates  must be signed by the
authorized representative of the insurance company shown on the certificate with
proof  that  he/she  is  an  authorized  representative  thereof.  In  addition,
certified,  true and exact  copies of all  project-specific  insurance  policies
required by this Contract other than professional  liability  insurance shall be
provided  to either  party  within a  reasonable  period  of time  upon  written
request.

        7.4.3   The insurance  provided by OWNER hereunder shall provide primary
property damage coverage with respect to the Work.

        7.4.4   Thirty (30)  calendar  Days'  written  notice  shall be given to
OWNER and CONTRACTOR of any  cancellation,  intent not to renew, or reduction in
the  policies'  coverage  except  in  the  application  of the  aggregate  limit
provisions.

        7.4.5   Prior to commencing  any Work at the Jobsite,  CONTRACTOR  shall
furnish OWNER with a  certificate(s)  of insurance  giving evidence of insurance
required  by Section  7.2 and  evidence  of  additional  insurance  endorsements
required by Sections 7.2.7 and 7.4.1.

                                  Page 26 of 32


        Additionally,  CONTRACTOR shall furnish a certificate(s) of insurance or
a policy binder(s) of insurance,  evidencing  replacement  coverage, to OWNER at
least 7 Days prior to expiration of any such policies, so that there shall be no
interruption in Work due to lack of proof of insurance coverage required by this
Contract.  If such  documentation is not available 7 Days prior to expiration of
any such policy(s),  CONTRACTOR shall provide OWNER with a notice,  stating with
specificity  the  status  of  such  renewal,  and  shall  provide  OWNER  with a
certificate(s)  of  insurance  or a policy  binder(s) of insurance as soon as is
reasonably  practicable.  OWNER  shall not be liable for any delays (or costs or
damages  resulting there from) resulting from  CONTRACTOR'S  failure (or that of
any  subcontractor  of any tier) to obtain the  insurance  required  of it under
Section 7.2, or to deliver the required certificates of insurance to OWNER.

        Certificates  of insurance  shall provide for at least thirty (30) Days'
prior  written  notice  to OWNER of  cancellation  (unless  cancellation  is for
nonpayment of premium,  in which case 10 Days' notice will suffice) or materials
alteration,  and shall delete the words  "endeavor  to" from the  obligation  to
notify the certificate holder (OWNER) of such cancellation or modification. Upon
advance written request of OWNER,  CONTRACTOR  shall permit OWNER to review,  at
CONTRACTOR'S  office, a copy of any policy of insurance required by Section 7.2,
from which may be redacted premium information.

        7.4.6   The insurance  coverages and limits required under this Contract
are designed to meet the minimum requirements of OWNER. They are not designed as
a  recommended  insurance  program for  CONTRACTOR  or its  subcontractors,  and
meeting  these  minimum  requirements  does not  relieve  such  persons of their
obligations under Section 7.1.

        7.4.7   The amounts and types of Commercial General Liability  insurance
shall conform to the minimum requirements set forth in this Article 7, utilizing
insurance  Services  Office (ISO) policies or the  equivalent  and  endorsements
where applicable.

        7.4.8   The acceptance of delivery of any  certificates  of insurance or
certified insurance policies required to be purchased and maintained pursuant to
this Contract does not  constitute  approval or agreement by the recipient  that
the insurance requirements have been met or that those certificates of insurance
policies are in compliance with this Contract.

        7.4.9   All of the insurance  required by this Article 7 shall be issued
as required by law and shall be endorsed,  where  necessary,  to comply with the
minimum  requirements  contained  herein.  Certificates  of insurance,  or other
reasonably  available  evidence of  insurance  coverage as  specified in Section
7.4.5  above,  must be provided at least 7 Days prior to  expiration  of current
policies so that there shall be no  interruption in Work due to lack of proof of
insurance coverage as required in this Contract.

        7.4.10  OWNER may elect at any time during the term of this  Contract to
require  CONTRACTOR  to procure and maintain  other or  additional  commercially
available insurance.  Notice of such election shall be given at least sixty (60)
Days prior to the effective date of the required  modifications,  Any additional
costs  incurred by these  parties in securing  insurance  shall be reimbursed by
OWNER as a part of the cost of the Work,  and the Lump Sum Contract  Price shall
be  revised by Change  Order to be  increased  by the amount of such  additional
reimbursement.

ARTICLE 8. RESOLUTION OF DISPUTES

        If at any time any controversy  shall arise between OWNER and CONTRACTOR
with respect to any matter or thing involved in this Contract, or arising out of
or related to subject matter of this Contract, and which OWNER and CONTRACTOR do
not promptly  adjust and determine,  and upon  completion of the Work and before
the final  settlement  and  payment is made said  controversy  shall be resolved
first by a meeting  between the Project  Management  Committee of the respective
parties  involved.  Should  agreement still not be reached within ten (10) Days,
said  controversy  shall be  resolved by a meeting  between the chief  executive
officers of the  respective  parties  involved.  Should  agreement  still not be
reached within twenty-four (24) hours, the parties may agree to mediate. If they
do not agree to mediate,  or if mediation is unsuccessful,  the parties agree to
be subject to binding  arbitration in accordance with the most current Rules for
Construction Disputes of the American Arbitration Association (AAA). If the Work
or any part of the Work is being  delayed,  the  arbitration  must  result in an
interim  ruling  within  ninety (90) Days of  submission.  The award shall be in
writing and shall include  findings of fact and conclusions of law in support of
the award.  The award will be final and  binding and may be entered in any court
of competent jurisdiction.  All disputes and/or claims less than or equal to One
Hundred  Thousand  Dollars  ($100,000.00)  in  value  shall  be  before a single
arbitrator and disputes and/or claims in excess of that amount shall be before a
panel of three  arbitrators,  all appointed in accordance  with said Rules.  The
parties  shall split evenly the costs of all  arbitrators'  fees,  and all costs
assessed  by the AAA.  Each party  shall bear its own cost of  arbitration.  The
arbitration  shall take place in Dallas,  Texas and Texas law shall  apply.  The
arbitrator(s)  shall have no  authority to award relief that is precluded by the
terms of this Contract.  CONTRACTOR shall require its subcontractors to agree in
writing to submit to the jurisdiction of arbitration.
