percent  (10%).  Pending  final  determination  of  amounts  to be  paid  to the
Subcontractor for changes in the Work, amounts not in dispute may be included as

incomplete  Work and unsettled  claims;  and, if final  completion of the entire
Work is thereafter  materially  delayed through no fault of the Subcontractor in
accordance with Subparagraph 9.10.3 of the General Conditions.

(if it is intended,  prior to  Substantial  Completion of the entire Work of the
Contractor,  to reduce or limit the retainage from Subcontractors resulting from
the percentages  inserted in Subparagraphs  12.7.1 and 12/7.2 above, and this is
not explained  elsewhere in the Contract  Documents,  insert here provisions for

by the Contractor to the  Subcontractor for the  Subcontractor's  performance of
the subcontract.

deemed to represent that the Architect has made a detailed examination, audit or
arithmetic  verification  of the  documentation  submitted  in  accordance  with
Paragraph 12.4 or other  supporting data: that the Architect has made exhaustive
or continuous on-site inspections or that the Architect has made examinations to
ascertain how or for what purposes the  Contractor  has used amounts  previously

required by the Owner,  will be performed by the Owner's  accountants  acting in
the sole interest of the Owner.


                                   ARTICLE 13
                                  FINAL PAYMENT

13.1.  Final payment shall be made by the Owner to the  Contractor  when (1) the
Contract has been fully performed by the contractor  except for the contractor's
responsibility  to correct  defective  or  nonconforming  Work,  as  provided in
Subparagraph   12.2.2  of  the  General   Conditions,   and  to  satisfy   other
requirements,  if any,  which  necessarily  survive final  payment:  (2) a final
Application  for  Payment and a final  accounting  for the Cost of the Work have
been submitted by the Contractor  and reviewed by the Owner's  accountants;  and
(3) a final Certificate for Payment has then been issued by the Architect;  such
final  payment  shall be made by the  Owner  not  more  than 30 days  after  the
issuance of the Architect's final Certificate for Payment:

13.2. The amount of the final Payment shall be calculated as follows:

13.2.1.  Take the sum of the Cost of the Work  substantiated by the Contractor's
final  accounting  and the  Contractor's  Fee; but not more than the  Guaranteed
Maximum Price, if any.

13.2.2. Subtract amounts, if any, for which the Architect withholds, in whole or
in part, a final  Certificate for Payment as provided in  Subparagraph  9.5.1 of
the General Conditions or other provisions of the Contract Documents.

13.2.3. Subtract the aggregate of previous Payments made by the Owner.

If the  aggregate Of Previous  payments made by the Owner exceeds the amount due
the Contractor, the Contractor shall reimburse the difference to the Owner.

13.3.  The  Owner's  accountants  will  review  and  report  in  writing  on the
Contractor's  final  Accounting  within  30 days  after  delivery  of the  final
accounting to the Architect by the Contractor.  Based upon such Cost of the Work
as the Owner's  accountants report to be substantiated by the Contractor's final
accounting,  and provided the other  conditions of Paragraph 13.1 have been met,
the Architect will, within seven days after receipt of the written report of the
Owner's  accountants,  either issue to the Owner a final Certificate for Payment
with a copy to the Contractor,  or notify the Contractor and Owner in writing of
the   Architect's   reasons  for   withholding  a  Certificate  as  provided  in
Subparagraph  9.5.1 of the General  Conditions.  The time periods stated in this
Paragraph  13.3  supersede  those  stated in  Subparagraph  9.4.1 of the General
Conditions.

13.4. If the Owner's accountants report the Cost of the Work as substantiated by
the Contractor's final accounting to be less than claimed by the Contractor, the
Contractor  shall be  entitled  to demand  arbitration  of the  disputed  amount
without a further decision of the Architect.  Such demand for arbitration  shall
be made by the  Contractor  within 30 days after the  Contractor's  receipt of a
copy of the  Architect's  final  Certificate  for  Payment;  failure  to  demand
arbitration  within this 30-day period shall result in the substantiated  amount
reported by the Owner's accountants becoming binding on the


                                       11



Contractor.  Pending a final resolution by arbitration.  the Owner shall pay the
Contractor  the  amount  certified  in the  Architect's  final  Certificate  for
Payment.

13.5. If, subsequent to final payment and at the Owner's request, the Contractor
incurs  costs  described  in Article 7 and not  excluded by Article 8 to correct
defective or  nonconforming  Work, the Owner shall reimburse the Contractor such
costs and the Contractor's  FCC applicable  thereto on the same basis as if such
costs  had been  incurred  prior  to final  payment,  but not in  excess  of the
Guaranteed  Maximum Price, if any. If the Contractor has participated in savings
as provided in Paragraph  5.2, the amount of such savings shall be  recalculated
and  appropriate  credit given to the Owner in determining  the net amount to be
paid by the Owner to the Contractor.


                                   ARTICLE 14

to the sole negligence of a party seeking indemnity.

substances were required by the Contract Documents.

by the Contract Documents, the Owner shall indemnify the Contractor for all cost
and expense thereby incurred.  The obligations of the Owner as set forth in this
paragraph shall survive the termination of the Contract."

o    Subparagraphs 10.1.2 through 10.1.4,  delete in its entirety and substitute
     the following:

10.1.2 If  reasonable  precautions  will be  inadequate  to prevent  foreseeable
bodily  injury or death to  persons  resulting  from a  material  or  substance,
including  but not  limited  to  asbestos  or  polychlorinated  biphenyl  (PCB),
encountered  on  the  site  by  the  Contractor,   the  Contractor  shall,  upon
recognizing the condition, immediately stop Work in the affected area and report
the condition to the Owner and Architect in writing.

10.1.3 The Owner shall  obtain the services of a licensed  laboratory  to verify
the presence or absence of the material or substance  reported by the Contractor
and, in the event such  material or substance is found to be present,  to verify
that it has been rendered  harmless.  Unless otherwise  required by the Contract
Documents,  the Owner shall furnish into the  Contractor and Architect the names
and  qualifications of persons or entities who are to performing tests verifying
the presence or absence of such  material or substance or who are to perform the
task of removal or safe,  containment material or substance.  The Contractor and
the Architect will promptly reply to the Owner in writing stating whether or not
either has  reasonable  objection  to the  persons or  entities  proposed by the
Owner.  If either the  Contract or  Architect  has an  objection  to a person or
entity  proposed  by the  Owner,  the  Owner  shall  propose  another  whom  the
Contractor and the Architect have no reasonable objection.  When the material or
substance  has been  rendered  harmless,  Work in the affected area shall resume
upon written  agreement of the Owner and Contractor.  The Contract Time shall be
extended  appropriately and the Contract Sum shall be increased in the amount of
the Contractor's  reasonable additional costs of shut-down,  delay and start-up,
which adjustments shall be accomplished as provided in Article 7.

10.1.4 To the fullest  extent  permitted by law, the Owner shall  indemnify  and
hold harmless the Contractor, Subcontractors, Architect, Architect's consultants
and agents and employees of any of them from and against claims, damages, losses
and expenses,  including but not limited to attorneys'  fees,  arising out of or
resulting  from  performance  of the  Work in the  affected  area if in fact the
material or substance  presents the risk of bodily  injury or death as described
in Subparagraph  10.1.2 and has not been rendered  harmless,  provided that such
claim,  damage,  loss or expense is  attributable  to bodily  injury,  sickness,
disease or death,  or to injury to or  destruction of tangible  property  (other
than the Work itself) and provided that such damage,  loss or expense is not due
to the sole negligence of a party seeking indemnity.

10.1.5 The Owner shall not be responsible  under Paragraph  10.1.4 for materials
and substances  brought to the site by the  Contractor  unless such materials or
substances were required by the Contract Documents.

10.1.6 If, without  negligence on the part of the Contractor,  the Contractor is
held liable for the cost of  remediation  of a hazardous  material or  substance
solely by reason of performing Work as required by the Contract  Documents,  the
Owner shall indemnify the Contractor for all cost and expense thereby  incurred.
The  obligations of the Owner as set forth in this  paragraph  shall survive the
termination of the Contract."
