schedule including any revisions thereto.

employees, subcontractors or suppliers so as to cause any additional cost,
expense, liability or damage to Turner including legal fees and disbursements
incurred by Turner (whether incurred in defending claims arising from such delay
or in seeking reimbursement and indemnity from the Subcontractor and its surety
hereunder or otherwise) or to the Development Manager or to Owner or any damages
or additional costs or expenses for which Turner or the Development Manager or
the Owner may or shall become liable, the Subcontractor and its surety shall and

provisions of this Agreement or of any of the other Contract Documents, Turner

rates which have been approved by Turner plus taxes imposed by law on such
additional wages, plus worker's compensation insurance, liability insurance and
levies on such additional wages if required to be paid by the Subcontractor.

     If, however, the progress of the Work or of the Project be delayed by any
fault or neglect or act or failure to act of the Subcontractor or any of its

Subcontractor shall, in addition to all of the other obligations imposed by this
Agreement upon the Subcontractor in such case, and at its own cost and expense,

completion of the Work and of the Project due to such delay. Should the
Subcontractor fail to make up for the time lost by reason of such delay, Turner
shall have the right to require other Subcontractors to work overtime and to
take whatever other action it deems necessary to avoid delay in the completion
of the Work and of the Project and the cost and expense of such overtime and/or
such other action shall be borne by the Subcontractor. [Add Rider X (page 3F)

Price

     ARTICLE IV. The sum to be paid by Turner, out of funds received from The
Development Manager or Owner to the Subcontractor for the satisfactory
performance and completion of the Work and of all of the duties, obligations and
responsibilities of the Subcontractor under this Agreement and the other
Contract Documents shall be UNIT RATE NOT TO EXCEED FOUR MILLION ($4,000,000)
DOLLARS (the "Maximum Unit Rate") UNIT RATES IS IN ACCORDANCE WITH THE ATTACHED
PAGE (hereinafter called the Price) subject to additions and deductions as
herein provided. [Insert Rider Y (page 3F) here]

     It is specifically understood and agreed that the Subcontractor and Turner
acknowledge that there is a risk that the Development Manager or Owner, in
breach of the contract with Turner, may make late payments or may, under certain
circumstances such as insolvency, not make required payments to Turner. The
parties furthermore acknowledge their agreement that they shall share the risk
of same. As a consequence of the foregoing understanding and consistent with
that allocation of risk, the Subcontractor agrees that Turner's receipt of
payment from the Development Manager or Owner on behalf of the Subcontractor's
requisitions for payment (whether interim requisitions or final requisitions
including [illegible]) shall be, to the fullest extent provided by law, a
condition precedent to the right of the Subcontractor to receive payment from
Turner. In the event that Turner is not receiving proper payment from the
Development Manager or Owner on account of the Work of the Subcontractor such
that Turner is not required to make payment to the Subcontractor hereunder,
Turner may in its sole discretion and to the extent it is legally able to do so,
formally and in writing assign to the Subcontractor the right of Turner to
pursue claims against the Owner for the payment due to Turner on behalf of the
Subcontractors's entitlement under the terms of the Subcontract, which
assignment Subcontractor shall be obliged to accept in full and complete
liquidation of the obligations to payment of Turner to Subcontractor hereunder.
The parties further acknowledge that the Subcontractor is entitled to pursue any
and all rights to which it may be entitled under the New York Lien Law in the
event that Turner does not pay the Subcontractor amounts due hereunder,
including non-payment resulting from delayed payments or non-payment by the
Development Manager or Owner to Turner. To the extent that this clause is
inconsistent with such lien rights, this clause is deemed waived for such
purpose only. In the event that Turner advises Subcontractor that Turner is
unable to pay Subcontractor by reason of the Development Manager's or Owner's
non-payment to Turner, Subcontractor agrees that the filing of a lien in full
accordance with the Lien Law and the complete prosecution of that lien claim to
finality in the courts, and collection therefrom, for the amount due to it shall
be a condition precedent to the right of the Subcontractor to file an action in
law or equity against Turner or its surety in connection with the project.
Further, nothing herein shall be deemed to subrogate or waive the
Subcontractor's right to the claims against Turner's sureties, if any. In the
event that Subcontractor files a claim against any or all of Turner's sureties,
Subcontractor agrees to stay any proceedings against Turner's sureties pending
the resolution of its mechanic's lien action to finality in the courts,
including collection therefrom. Furthermore, nothing herein is intended to limit
or preclude the rights of the Contractor under other terms of this Subcontract
to backcharges, set-offs or other claims against the Subcontractor in regard to
the matters addressed in this Clause or otherwise.

     Except as set forth in the provisions on pages 3A-3F, the Price includes
all Federal, State, County, Municipal and other taxes imposed by law and based
upon labor, services, materials, equipment or other items required, performed,
furnished or used for and in connection with the Work including but not limited
to sales, use and personal property taxes payable by or levied or assessed
against the Owner, Turner or the Subcontractor. Where the law requires any such
taxes to be stated and charged separately, the total price of all items included
in the Work plus the amount of such taxes shall not exceed the Price.

                                      -2-

Monthly Estimate

     On or before the last day of each month the Subcontractor shall submit to
Turner, in the form required by Turner, a written requisition for payment
showing the proportionate value of the Work installed to that date, from which
shall be deducted a reserved five per cent (5%), all previous payments and all
charges for services, materials, equipment and other items furnished by Turner
to or chargeable to the Subcontractor, and the balance of the amount of such
requisition, as approved by Turner and the [illegible] and for which payment has
been received by Turner from the Development Manager or Owner, shall be due and
paid to the Subcontractor on or about the fifteenth (15th) day of the succeeding
month or in accordance with the Contract Documents.

     The obligation of Turner to make a payment under this Agreement, whether a
progress or final payment, or for extras or charge orders or delays to the Work,
is subject to the express condition precedent of payment therefor by the
Development Manager or Owner. If Turner has provided payment or performance
bonds or a combination payment and performance bond, the obligation of Turner
and its surety under any of these bonds to make any payment (whether a progress
payment or final payment) to a claimant on that bond is similarly subject to the
express condition precedent of payment therefor by the Development Manager or
Owner.

     The Subcontractor shall submit with its first requisition for payment a
detailed schedule showing the breakdown of the Price into its various parts for
use only as a basis of checking the Subcontractor's monthly requisitions.

     Turner reserves the right to advance the date of any payment (including the
final payment) under this Agreement if, in its sole judgment, it becomes
desirable to do so.

     The Subcontractor agrees that, if and when requested to do so by Turner, it
shall furnish such information, evidence and substantiation as Turner may
require with respect to the nature and extent of all obligations incurred by the
Subcontractor for or in connection with the Work, or payments made by the
Subcontractor thereon and the monies remaining unpaid, to whom and the reasons
therefor.

Final Payment

     Final payment to the  Subcontractor  shall be within 30 days of substantial
completion of the Work.

Payments

     If any claim or lien is made or filed with or against Turner, the Owner,
the Project, the Premises or the Project funds by any person claiming that the
Subcontractor or any subcontractor or other person under subcontract has failed
to make payment for any labor, services, materials, equipment, taxes or other
items or obligations furnished or incurred for or in connection with the Work,
or if at any time there shall be evidence of such nonpayment or of any claim or
lien for which, if established, Turner or the Development Manager or Owner might
become liable and which is chargeable to the Subcontractor, or if the
Subcontractor or any subcontractor or other person under subcontract causes
damage to the Work or to any other work on the Project, or if the Subcontractor
fails to perform or is otherwise in default under any of the terms or provisions
of this Agreement, Turner shall have the right to retain from any payment then
due or thereafter to become due an amount which it deems sufficient to (1)
satisfy, discharge and/or defend against any such claim or lien or any action
which may be brought or judgment which may be recovered thereon, (2) make good
any such nonpayment, damage, failure or default, and (3) compensate Turner and
the Development Manager or Owner for and indemnify and hold them harmless
against any and all losses, liability, damages, costs and expenses, including
legal fees and disbursements, which may be sustained or incurred by either or
both of them in connection therewith. Turner shall have the right to apply and
charge against the Subcontractor so much of the amount retained as may be
required for the foregoing purposes. If the amount is insufficient therefor, the
Subcontractor shall be liable for the difference and pay the same to Turner.

Payments and Non Acceptance

     No payment (final or otherwise) made under or in connection with this
Agreement shall be conclusive evidence of the performance of the Work or of the
Agreement, in which or in part, and no such payment shall be construed to be an
acceptance of defective, faulty or improper work or materials nor shall it
release the Subcontractor from any of its obligations under this Agreement, nor
shall entrance and use by the Owner, or any Designee of Owner constitute
acceptance of the Work of any part thereof.

Subcontractor, a copy of which is attached as Exhibit A hereto, which Turner
hereby accepts, is incorporated herein by reference and constitutes an integral
part of this Agreement (the "Proposal"). Should any provisions of this Agreement
conflict with provisions contained in the Proposal, the provisions in the

     The Subcontractor shall prepare a Preliminary Work Plan - Means and Methods

extent permitted by law, by this clause. Subcontractor agrees that its rights to

subcontract. Subcontractor agrees that it shall not file liens for any sum which

liens for some which it may contend are due as damages by reason of delays or
other such claims unless such sums are agreed due to Subcontractor by written

permissible hereunder or pursuant to law, or which is negligently or

labor, services, materials, supplies, equipment or other items performed or
furnished for or in connection with the Work or under any change order or
supplemental agreement for extra or additional work in connection with the
Project, the Subcontractor agrees to cause such liens and claims to be
satisfied, removed or discharged at his own expense by bond, payment or
otherwise within ten (10) days from the date of the filing thereof, and upon its
failure to do so Turner shall have the right, in addition to all other rights
and remedies provided under this Agreement and the other Contract Documents or
by law, to cause such items or claims to be satisfied, remedied or discharged by
whatever means Turner chooses, at the entire cost and expense of the
Subcontractor (such cost and expense to include legal fees and disbursements).

Owner from and against any and all such liens and claims and actions brought or

duties or obligations arising under this Agreement including, but not limited
to, any right to receive payments hereunder, without the prior written consent
of Turner in its sole discretion and the giving of any such consent to a
particular assignment shall not dispense with the necessity of such consent to
any further or other assignments. In the event subcontractor assigns, sells,
encumbers or otherwise transfers its right to any monies due or to become due
under this Agreement or security for any loan, financing or other indebtedness
(hereafter "Assignment"), notification to Turner of such Assignment must be sent
by courier mail, return receipt requested, to the Purchasing Manager in charge
of the business unit responsible for the construction of the Project and the
Assignment shall not be effective as against Turner until Turner provides its
written consent to such Assignment. Subcontractor agrees that any such
Assignment shall not relieve Subcontractor of any of its agreements, duties,
responsibilities or obligations under this Agreement and the other Contract
Documents and shall not create a contractual relationship or a third party
beneficiary relationship of any kind between Turner and such assignee or
transferee. Subcontractor further

                                      -7-

<PAGE>

with respect to such Assignment are reserved, unless expressly waived in writing
by a duly authorized corporate officer. Subcontractor hereby agrees to indemnify
and hold harmless Turner form and against any and all lost, cost, expense or
damages Turner or Owner has or may sustain or incur in connection with such
Assignment.

the Subcontractor, to terminate this Agreement without cause and require the
Subcontractor to cease work hereunder, in which case, provided the Subcontractor

damage directly resulting from such termination. In the event of such a
termination for convenience, the Subcontractor shall be entitled to payment
pursuant to the terms of the subcontract for all Work performed as of the date
of termination, together with reasonable costs of remediation and such other
reasonable costs as may be encountered by the Subcontractor and directly
attributable to such termination. However, the Subcontractor shall only be
entitled to profit on that portion of the work actually performed and approved
for payment to the date of termination together with retainages held upon
payments made prior thereto. Subcontractor waives any claim for loss of
anticipated profits in the event Turner exercises this clause.

workmen charged upon or in the Work is its responsibility. The Subcontractor
agrees to comply with all Federal, State, Municipal and local laws, vicinity of
the ordinances, rules, regulations, codes, standards, orders, notices and
requirements concerning safety as shall be applicable to the Work, including,
among others, the Federal Occupational Safety and Health Act of 1970, as
amended, and all standards, rules, regulations and orders which have been or
shall be adopted or issued thereunder, and with the safety standards established
during the progress of the Work by Turner. When so ordered, the Subcontractor
shall stop any part of the Work which Turner deems unsafe until corrective
measures satisfactory to Turner have been taken, and the Subcontractor agrees
that it shall not have nor make any claim for damages growing out of such
stoppages. Should the Subcontractor neglect to take such corrective measures,
Turner may do so at the cost and expense of the Subcontractor and may deduct the
cost thereof from any payments due or to become due to the Subcontractor.
Failure on the part of Turner to stop unsafe practices shall in no way relieve
the Subcontractor of his responsibility therefor.

     The Subcontractor acknowledges the receipt of The Turner Corporation's
policies on "Safety", "Drug and Alcohol Abuse" and "Sexual Harassment". Subject
to applicable law this Subcontractor further agrees to be bound to those
policies as a part of the supplemental and special conditions to the contract
for construction of the project.

     In the event that hazardous substances of a type of which an employer is
required by law to notify its employees are being used or stored on the site by
the Subcontractor, the Subcontractor's sub-subcontractor and anyone directly or
indirectly employed or otherwise retained by them or either of them, the
Subcontractor shall immediately provide written notice of the chemical
composition thereof (including, without limitation, a copy of the applicable
Material Safety Date Sheet) to Turner, in sufficient time to permit compliance
with such laws by Turner, other subcontractors and other employees on the site.
In the event that the Subcontractor encounters on the site material reasonably
believed to be hazardous substances (including, without limitation, asbestos or
polychlorinated byphenyl) which has not been rendered harmless,
the Subcontractor shall immediately stop Work only in the area affected and
immediately report the condition to Turner in writing. Work in the affected area

extent of Subcontractor's responsibilities hereunder, Subcontractor does
indemnify and save harmless Turner from and against any and all loss, injury,
claims, actions, proceedings, liability, damages, fines, penalties, cost and
expenses, including legal fees and disbursements, caused or occasioned directly
or indirectly by the Subcontractor in regard to such hazardous substances.
