perform with the Contractor's own personnel shall be performed under
subcontracts or by other appropriate agreements with the Contractor. The
Contractor shall obtain bids from Subcontractors and from suppliers of materials

entity designated by the Owner.

10.3      Subcontracts or other agreements shall conform to the payment
provisions of Paragraphs 12.7 and 12.8, and shall not be awarded on the basis of
cost plus a fee without the prior consent of the Owner.

Contractor and Certificates for Payment issued by the Architect, the Owner shall
make progress payments on account of the Contract Sum to the Contractor as
provided below and elsewhere in the Contract Documents.

12.2      The period covered by each Application for Payment shall be one
calendar month ending on the last day of the month, or as follows:

12.3      Provided an Application for Payment is received by the Architect not
later than the last day of a month, the Owner shall make payment to the
Contractor not later than the fifteenth day of the month. If an Application for
Payment is received by, the Architect after the application date fixed above,
payment shall be made by the Owner not later than fifteen days after the
Architect receives the Application for Payment.

12.4      With each Application for Payment the Contractor shall submit
payrolls, petty cash accounts, receipted invoices or invoices with check
vouchers attached, and any other evidence required by the Owner or Architect to
demonstrate that cash disbursements already made by the Contractor on account of

Contractor's Fee; plus (3) payrolls for the period covered by the present
Application for Payment; plus (4) retainage provided in Subparagraph 12.5.4, if
any, applicable to prior progress payments.

schedule of values submitted by the Contractor in accordance with the Contract
Documents. The schedule of values shall allocate the entire Guaranteed Maximum
Price among the various portions of the Work, except that the Contractor's Fee
shall be shown as a single separate item. The schedule of values shall be
prepared in such form and supported by such data to substantiate its accuracy as
the Architect may require. This schedule, unless objected to by the Architect,
shall be used as a basis for reviewing the Contractor's Applications for
Payment.

12.5.2    Applications for Payment shall show the percentage completion of each
portion of the Work as of the end of the period covered by the Application for
Payment. The percentage completion shall be the lesser of (1) the percentage of
that portion of the Work which has actually been completed or (2) the percentage
obtained by dividing (a) the expense which has actually been incurred by the
Contractor on account of that portion of the Work for which the Contractor has
made or intends to make actual payment prior to the next Application for Payment
by (b) the share of the Guaranteed Maximum Price allocated to that portion of
the Work in the schedule of values.
<PAGE>
 
12.5.3    Subject to other provisions of the Contract Documents, the amount of
each progress payment shall be computed as follows:

12.5.3.1  Take that portion of the Guaranteed Maximum Price properly allocable
to completed Work as determined by multiplying the percentage completion of each
portion of the Work by the share of the Guaranteed Maximum Price allocated to
that portion of the Work in the schedule of values. Pending final determination
of cost to the Owner of changes in the Work, amounts not in dispute may be
included as provided in Subparagraph 7.3.7 of the General Conditions, even
though the Guaranteed Maximum Price has not yet been adjusted by Change Order.

12.5.3.2  Add that portion of the Guaranteed Maximum Price properly allocable to
materials and equipment delivered and suitably stored at the site for subsequent
incorporation in the Work or, if approved in advance by the Owner, suitably

12.5.3.3  Add the Contractor's Fee, less retainage of percent( %). The
Contractor's Fee shall be computed upon the Cost of the Work described in the
two preceding Clauses at the rate stated in Paragraph 5.1 or, if the
Contractor's Fee is stated as a fixed sum in that Paragraph, shall be an amount
which bears the same ratio to that fixed-sum Fee as the Cost of the Work in the
two preceding Clauses bears to a reasonable estimate of the probable Cost of the
Work upon its completion.

12.5.3.4  Subtract the aggregate of previous payments made by the Owner.

12.5.3.5  Subtract the shortfall, if any, indicated by the Contractor in the
documentation required by Paragraph 12.4 to substantiate prior Applications for
Payment, or resulting from errors subsequently discovered by the Owner's
accountants in such documentation.

12.5.3.6  Subtract amounts, if any, for which the Architect has withheld or
nullified a Certificate for Payment as provided in Paragraph 9.5 of the General
Conditions.

12.5.4  Additional retainage, if any, shall be as follows:

(If it is intended to retain additional amounts from progress payments to the
Contractor beyond (1) the retainage from the Contractor's Fee provided in Clause
12.5.3.3, (2) the retainage from Subcontractors provided in Paragraph 12.7
below, and (3) the retainage, if any, provided by other provisions of the
Contract, insert provision for such additional retainage here. Such provision,
if made, should also describe any arrangement for limiting or reducing the
amount retained after the Work reaches a certain state of completion.)

12.6      CONTRACTS WITHOUT A GUARANTEED MAXIMUM PRICE

12.6.1    Applications for Payment shall show the Cost of the Work actually
incurred by the Contractor through the end of the period covered by the
Application for Payment and for which the Contractor has made or intends to make
actual payment prior to the next Application for Payment.

12.6.2    Subject to other provisions of the Contract Documents, the amount of
each progress payment shall be computed as follows:

12.6.2.1  Take the Cost of the Work as described in Subparagraph 12.6. 1.

12.6.2.2  Add the Contractor's Fee, less retainage of Ten percent (10%). The
Contractor's Fee shall be computed upon the Cost of the Work described in the
preceding Clause 12.6.2.1 at the rate stated in Paragraph 5.1 or, if the
Contractor's Fee is stated as a fixed sum in that Paragraph, an amount which
bears the same ratio to that fixed-sum Fee as the Cost of the Work in the
preceding Clause bears to a reasonable estimate of the probable Cost of the Work
upon its completion.

12.6.2.3  Subtract the aggregate of previous payments made by the Owner.

12.6.2.4  Subtract the shortfall, if any, indicated by the Contractor in the
documentation required by Paragraph 12.4 or to substantiate prior Applications
for Payment or resulting from errors subsequently discovered by the Owner or
Owner's representatives in such documentation.

12.6.2.5  Subtract amounts, if any, for which the Architect has withheld or
withdrawn a Certificate for Payment as provided in the Contract Documents.

12.6.3    Additional retainage, if any, shall be as follows:
<PAGE>
 
12.7      Except with the Owner's prior approval, payments to Subcontractors
included in the Contractor's Applications for Payment shall not exceed an amount
for each Subcontractor calculated as follows:

12.7.1    Take that portion of the Subcontract Sum properly allocable to
completed Work as determined by multiplying the percentage completion of each
portion of the Subcontractor's Work by the share of the total Subcontract Sum
allocated to that portion in the Subcontractor's schedule of values, less
retainage of Ten percent (10%). Pending final determination of amounts to be
paid to the Subcontractor for changes in the Work, amounts not in dispute may hb
included as provided in Subparagraph 7.3.7 of the General Conditions even though
the Subcontract Sum has not yet been adjusted by Change Order.

12.7.2    Add that portion of the Subcontract Sum properly allocable to
materials and equipment delivered and suitability stored at the site for
subsequent incorporation in the Work or, if approved in advance by the Owner,
suitably stored off the site at a location agreed upon in writing, less
retainage of Ten percent (10 %).

12.7.3    Subtract the aggregate of previous payments made by the Contractor to
the Subcontractor.

12.7.4    Subtract amounts, if any, for which the Architect has withheld or
nullified a Certificate for Payment by the owner to the Contractor for reasons
which are the fault of the Subcontractor.

12.7.5    Add, upon Substantial and satisfactory Completion of the entire Work
of the Contractor. a sum sufficient to increase the total payments to the
Subcontractor to One Hundred percent (100 %) of the Subcontract Sum, less
amounts, if any, for incomplete Work and unsettled claims; and, if final
completion of the entire Work is thereafter materially delayed through no fault
of the Subcontractor and all of the work of the subcontractor has been
satisfactorily completed, add any additional amounts payable on account of Work
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 such reduction or limitation.)









The Subcontract Sum is the total amount stipulated in the subcontract to be paid
by the Contractor to the Subcontractor for the Subcontractor's performance of
the subcontract.

12.8      Except with the Owner's prior approval the Contractor shall not make
advance payments to suppliers for materials or equipment which have not been
delivered and stored at the site.

12.9      In taking action on the Contractor's Applications for Payment, the
Architect shall be entitled to rely on the accuracy and completeness of the
information furnished by the Contractor and shall not be 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 paid on account of
the Contract. Such examinations, audits and verifications, if required by the
Owner, will be performed by the Owner or Owner's representatives acting in the
sole interest of the Owner.

                                   ----------

                                  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, or as follows:








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 payment 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
Contractor. Such Arbitration shall be held in Rockville, Maryland in accordance
with the rules of the American Arbitration Association before a single
arbitrator.

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 Fee applicable thereto on the same
basis as if such costs had been incurred prior to few 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.

General Conditions or another Contract Document, the reference refers to that
provision as amended or supplemented by other provisions of the Contract
Documents.

the legal rate prevailing from time to time at the place where the Project is
located.
(Insert rate of interest agreed upon, if any.)

2 % Above Prime





(Usury laws and requirements under the Federal Thumb in Lending Act, similar
state and local consumer credit laws and other regulations at the Owner's and
Contractor's principle places of business, the location of the Project and
elsewhere may affect the validity of this provision. Legal advice should be
obtained with respect to deletions and modifications, and also regarding
requirements such as written disclosures or waivers.)

14.3      Other provisions:

without the prior written consent of the Owner. The Owner may assign this
agreement to a successor in interest to its assets.

                            TERMINATION OR SUSPENSION

15.1      The Contract may be terminated by the Contractor as provided in
Article 14 of the General Conditions-. however, the amount to be paid to the
Contractor under Subparagraph 14.1.2 of the General Conditions shall not exceed
the amount the Contractor would be entitled to receive under Paragraph 15.3
below.

15.2      If a Guaranteed Maximum Price is established in Article 5, the
Contract may be terminated by the Owner for cause as provided in Article 14 of
the General Conditions; however, the amount, if any, to be paid to the
Contractor under Subparagraph 14.2.4 of the General Conditions shall not cause
the Guaranteed Maximum Price to be exceeded, nor shall it exceed the amount the
Contractor would be entitled to receive under Paragraph 15.3 below.

15.3      If no Guaranteed Maximum Price is established in Article 5, the
Contract may be terminated by the Owner for cause as provided in Article 14 of
the General Conditions; however, the Owner shall then pay the Contractor an
amount calculated as follows.

15.3.1    Take the Cost of the Work incurred by the Contractor to the date of
termination.

15.3.2    Add the Contractor's Fee computed upon the Cost of the Work to the
date of termination at the rate stated in Paragraph 5.1 or, if the Contractor's
Fee is stated as a fixed sum in that Paragraph, an amount which bears the same
ratio to that fixed-sum Fee as the Cost of the Work at the time of termination
bears to a reasonable estimate of the probable Cost of the Work upon its
completion.

15.3.3    Subtract the aggregate of previous payments made by the Owner.
<PAGE>
 
The Owner shall also pay the Contractor fair compensation, either by purchase or
rental at the election of the Owner, for any equipment owned by the Contractor
which the Owner elects to retain and which is not otherwise included in the Cost
of the Work under Subparagraph 15.3.1. To the extent that the Owner elects to
take legal assignment of subcontracts and purchase orders (including rental
agreements), the Contractor shall, as a condition of receiving the payments
referred to in this Article 15, execute and deliver all such papers and take all
such steps, including the legal assignment of such subcontracts and other
contractual rights of the Contractor, as the Owner may require for the purpose
of fully vesting in the Owner the rights and benefits of the Contractor under
such subcontracts or purchase orders.

15.4      The Work may be suspended by the Owner as provided in Article 14 of
the General Conditions; in such case, the Guaranteed Maximum Price, if any,
shall be increased as provided in Subparagraph 14.3.2 of the General Conditions
except that the term "cost of performance of the Contract" in that Subparagraph
shall be understood to mean the Cost of the Work and the term "profit" shall be
understood to mean the Contractor's Fee as described in Paragraphs 5.1 and 6.3
of this Agreement.

15.5      Should the contract be terminated by the Owner for cause, payment of
additional funds to contractor under paragraph 15.3 or otherwise shall not
affect any rights Owner may have under law to damages due to contractor actions
that give rise to the termination.
