12.1      The Contract Documents consist of this Agreement with Conditions of
the Contract (General, Supplementary and other Conditions), Drawings,
Specifications, addenda issued prior to execution of this Agreement, other
documents listed in this Agreement and Modifications issued after execution of
this Agreement. The intent of the Contract Documents is to include all items
necessary for the proper execution and completion of the Work by the Contractor.

required only to the extent consistent with the Contract Documents and
reasonably inferable from them as being necessary to produce the intended
results.

12.2      The Contract Documents shall not be construed to create a contractual
relationship of any kind (1) between the Architect and Contractor, (2) between
the Owner and a Subcontractor or Sub-subcontractor or (3) between any persons or
entities other than the Owner and Contractor.

12.3      Execution of the Contract by the Contractor is a representation that
the Contractor has visited the site and become familiar with the local
conditions under which the Work is to be performed.

12.4      The term "Work" means the construction and services required by the
Contract Documents, whether completed or partially completed, and includes all
other labor, materials, equipment and services provided or to be provided by the
Contractor to fulfill the Contractor's obligations. The Work may constitute the
whole or a part of the Project.

13.3      If the Contractor fails to correct Work which is not in accordance
with the requirements of the Contract Documents or persistently fails to carry
out the Work in accordance with the Contract Documents, the Owner, by a written
order, may order the Contractor to stop the Work, or any portion thereof, until
the cause for such order has been eliminated; however, the right of the Owner to
stop the Work shall not give rise to a duty on the part of the Owner to exercise
this right for the benefit of the Contractor or any other person or entity.

                                   ARTICLE 14

free from defects not inherent in the quality required or permitted, and that
the Work will conform with the requirements of the Contract Documents. Work not
conforming to these requirements, including substitutions not properly approved
and authorized, may be considered defective. The Contractor's warranty excludes
remedy for damage or defect caused by abuse, modifications not executed by the
Contractor, improper or insufficient maintenance, improper operation, or normal
wear and tear under normal usage. If required by the Architect, the Contract
shall furnish satisfactory evidence as to the kind and quality of materials and
equipment.

shall pay sales, consumer, use, and other similar taxes which are legally
enacted when bids are received or negotiations concluded, whether or not yet

Drawings, Product Data, Samples and similar submittals required by the Contract
Documents with reasonable promptness. The Work shall be in accordance with
approved submittals. When professional certification of performance criteria of
materials, systems or equipment is required by the Contract Documents, the
Architect shall be entitled to rely upon the accuracy and completeness of such
certifications.

14.9      The Contractor shall keep the premises and surrounding area free
from accumulation of waste materials or rubbish caused by operations under
the Contract. At completion of the Work the Contractor shall remove from and
about the Project waste materials, rubbish, the Contractor's tools, construction
equipment, machinery and surplus materials.

14.10     The Contractor shall provide the Owner and Architect access to the
Work in preparation and progress wherever located.

14.11     The Contractor shall pay all royalties and license fees; shall defend
suites or claims for infringement of patent rights and shall hold the Owner
harmless from loss on account thereof, but shall not be responsible for such
defense or loss when a particular design, process or product of a particular
manufacturer or manufacturers is required by the Contract Documents unless the
Contractor has reason to believe that there is an infringement of patent.

14.12     To the fullest extent permitted by law, the Contractor shall indemnify
and hold harmless the Owner, 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 resulting from
performance of the Work, 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) including loss of
use resulting therefrom, but only to the extent caused in whole or in part by
negligent acts or omissions of the Contractor, a Subcontractor, anyone directly
or indirectly employed by them or anyone for whose acts they may be liable,
regardless of whether or not such claim, damage, loss or expense is caused in
part by a party indemnified hereunder. Such obligation shall not be construed
to negate, abridge, or reduce other rights or obligations of indemnity which
would otherwise exist as to a party or person described in this Paragraph 14.12.

14.12.1   In claims against any person or entity indemnified under this
Paragraph 14.12 by an employee of the Contractor, a Subcontractor, anyone
directly or indirectly employed by them or anyone for whose acts they may be
liable, the indemnification obligation under this Paragraph 14.12 shall not be
limited by a limitation on amount or type of damages, compensation or benefits
payable by or for the Contractor or a Subcontractor under workers' or workmen's
compensation acts, disability benefit acts or other employee benefit acts.

14.12.2   The obligations of the Contractor under this Paragraph 14.12 shall not
extend to the liability of the Architect, the Architect's consultants, and
agents and employees of any of them arising out of (1) the preparation or
approval of maps, drawings, opinions, reports, surveys, Change Orders,
Construction Change Directives, designs or specifications, or (2) the giving of
or the failure to give directions or instructions by the Architect, the
Architect's consultants, and agents and employees of any of them provided such
giving or failure to give is the primary cause of the injury or damage.

                                   ARTICLE 15
                         ADMINISTRATION OF THE CONTRACT

15.1      The Architect will provide administration of the Contract and will be
the Owner's representative (1) during construction, (2) until final payment is
due and (3) with the Owner's concurrence, from time to time during the
correction period described in Paragraph 23.1.

15.2      The Architect will visit the site at intervals appropriate to the
stage of construction to become generally familiar with the progress and quality
of the completed Work and to determine in general if the Work is being performed
in a manner indicating that the Work, when completed, will be in accordance with
the Contract Documents. However, the Architect will not be required to make
exhaustive or continuous on-site inspections to check quality or quantity of the
Work. On the basis of on-site observations as an architect, the Architect will
keep the Owner informed of progress of the Work and will endeavor to guard the
Owner against defects and deficiencies in the Work.

15.3      The Architect will not have control over or charge of and will not be
responsible for construction means, methods, techniques, sequences or
procedures, or for safety precautions and programs in connection with the Work,
since these are solely the Contractor's responsibility as provided in
Paragraphs 14.1 and 21.1. The Architect will not be responsible for the
Contractor's failure to carry out the Work in accordance with the Contract
Documents.

15.4      Based on the Architect's observations and evaluations of the
Contractor's Applications for Payment, the Architect will review and certify the
amounts due the Contractor and will issue Certificates for Payment in such
amounts.

15.5      The Architect will interpret and decide matters concerning performance
under and requirements of the Contract Documents on written request of either
the Owner or Contractor. The Architect will make initial decisions on all
claims, disputes or other matters in question between the Owner and contractor,
but will not be liable for results of any interpretations or decisions rendered
in good faith. The Architect's decisions in matters relating to aesthetic effect
will be final if consistent with the intent expressed in the Contract Documents.
All other decisions of the Architect, except those which have been waived by
making or acceptance of final payments, shall be subject to arbitration upon the
written demand of either party.

15.6      The Architect will have authority to reject Work which does not
conform to the Contract Documents.

15.7.     The Architect will review and approve or take other appropriate action
upon the Contractor's submittals such as Shop Drawings, Product Data and
Samples, but only for the limited purpose of checking for conformance with
information given and the design concept expressed in the Contract Documents.

15.8      All claims or disputes between the Contractor and the Owner arising
out of or relating to the Contract Documents, or the breach thereof, shall be
decided by arbitration in accordance with the Construction Industry Arbitration
Rules of the American Arbitration Association currently in effect unless the
parties mutually agree otherwise and subject to an initial presentation of the
claim or dispute to the Architect as required under Paragraph 15.5. Notice of
the demand for arbitration shall be filed in writing with the other party to
this Agreement and with the American Arbitration Association and shall be made
within a reasonable time after the dispute has arisen. The

award rendered by the arbitrator or arbitrators shall be final, and judgment may
be entered upon it in accordance with applicable law in any court having
jurisdiction thereof. Except by written consent of the person or entity sought
to be joined, no arbitration arising out of or relating to the Contract
Documents shall include, by consolidation, joinder or in any other manner, any
person or entity not a party to the Agreement under which such arbitration
arises, unless it is shown at the time the demand for arbitration is filed that
(1) such person or entity is substantially involved in a common question of fact
or law, (2) the presence of such person or entity is required if complete relief
is to be accorded in the arbitration, (3) the interest or responsibility of such
person or entity in the matter is not insubstantial, and (4) such person or
entity is not the Architect or any of the Architect's employees or consultants.
The agreement herein among the parties to the Agreement and any other written
agreement to arbitrate referred to herein shall be specifically enforceable
under applicable law in any court having jurisdiction thereof.

                                   ARTICLE 16
                                  SUBCONTRACTS

16.1      A Subcontractor is a person or entity who has a direct contract with
the Contractor to perform a portion of the Work at the site.

16.2      Unless otherwise stated in the Contract Documents or the bidding
requirements, the Contractor, as soon as practicable after award of the
Contract, shall furnish in writing to the Owner through the Architect the names
of the Subcontractors for each of the principal portions of the Work. The
Contractor shall not contract with any Subcontractor to whom the Owner or
Architect has made reasonable and timely objection. The Contractors shall not be
required to contract with anyone to whom the Contractor has made reasonable
objection. Contracts between the Contractor and Subcontractors shall (1) require
each Subcontractor, to the extent of the Work to be performed by the
Subcontractor, to be bound to the Contractor by the terms of the Contract
Documents, and to assume toward the Contractor all the obligations and
responsibilities which the Contractor, by the Contract Documents, assumes toward
the Owner and Architect, and (2) allow to the Subcontractor the benefit of all
rights, remedies and redress afforded to the Contractor by these Contract
Documents.

                                   ARTICLE 17
                CONSTRUCTION BY OWNER OR BY SEPARATE CONTRACTORS

17.1      The Owner reserves the right to perform construction or operations
related to the Project with the Owner's own forces, and to award separate
contracts in connection with other portions of the Project or other construction
or operations on the site under conditions of the contract identical or
substantially similar to these, including those portions related to insurance
and waiver of subrogation. If the Contractor claims that delay or additional
cost is involved because of such action by the Owner, the Contractor shall make
such claim as provided elsewhere in the Contract Documents.

17.2      The Contractor shall afford the Owner and separate contractors
reasonable opportunity for the introduction and storage of their materials and
equipment and performance of their activities, and shall connect and coordinate
the Contractor's construction and operations with theirs as required by the
Contract Documents.

17.3      Costs caused by delays, improperly timed activities or defective
construction shall be borne by the party responsible therefor.

                                   ARTICLE 18
                               CHANGES IN THE WORK

18.1      The Owner, without invalidating the Contract, may order changes in the
Work consisting of additions, deletions or modifications, the Guaranteed Maximum
Cost, if any, and the Contract Time being adjusted accordingly. Such changes in
the Work shall be authorized by written Change Order signed by the Owner,
Contractor and Architect, or by written Construction Change Directive signed by
the Owner and Architect.

18.2      The Contract Sum and Contract Time shall be changed only by Change
Order.

18.3      The cost or credit to the Owner from a change in the Work shall be
determined by mutual agreement.

                                   ARTICLE 19
                                      TIME

19.1      Time limits stated in the Contract Documents are of the essence of the
Contract. By executing the Agreement the Contractor confirms that the Contract
Time is a reasonable period for performing the Work.

19.2      The date of Substantial Completion is the date certified by the
Architect in accordance with Paragraph 20.3.

19.3      If the Contractor is delayed at any time in progress of the Work by
changes ordered in the Work, by labor disputes, fire, unusual delay in
deliveries, abnormal adverse weather conditions not reasonably anticipatable,
unavoidable casualties or any causes beyond the Contractor's control, or by
other causes which the Architect determines may justify delay, then the Contract
Time shall be extended by Change Order for such reasonable time as the Architect
may determine.

                                   ARTICLE 20
                             PAYMENTS AND COMPLETION

20.1      Payments shall be made as provided in Articles 9 and 10 of this
Agreement.

20.2      Payments may be withheld on account of (1) defective Work not
remedied, (2) claims filed by third parties, (3) failure of the Contractor to
make payments properly to Subcontractors or for labor, materials or equipment,
(4) reasonable evidence that the Work cannot be completed for the unpaid balance
of the Guaranteed Maximum Price, if any, (5) damage to the Owner or another
contractor, (6) reasonable evidence that the Work will not be completed within
the Contract Time and that the unpaid balance of the Guaranteed Maximum Price,
if any, would not be adequate to cover actual or liquidated damages for the
anticipated delay, or (7) persistent failure to carry out the Work in accordance
with the Contract Documents.

20.3      When the Architect agrees that the Work is substantially complete, the
Architect will issue a Certificate of Substantial Completion.

20.4      Final payment shall not become due until the Contractor has delivered
to the Owner a complete release of all liens arising out of this Contract or
receipts in full covering all labor, materials and equipment for which a lien
could be filed, or a bond satisfactory to the Owner to indemnify the Owner
against such lien. If such lien remains unsatisfied after payments are made, the
Contractor shall refund to the Owner all money the Owner may be compelled to pay
in discharging such lien, including all costs and reasonable attorneys' fees.

20.5      The making of final payment shall constitute a waiver of claims by the
Owner except those arising from:

          .1   liens, claims, security interests or encumbrances arising out of
               the Contract and unsettled;

          .2   failure of the Work to comply with the requirements of the
               Contract Documents; or

          .3   terms of special warranties required by the Contract Documents.

Acceptance of final payment by the Contractor, a Subcontractor or material
supplier shall constitute a waiver of claims by that payee except those
previously made in writing and identified by that payee as unsettled at the time
of final Application for Payment.

                                   ARTICLE 21
                       PROTECTION OF PERSONS AND PROPERTY

21.1      The Contractor shall be responsible for initiating, maintaining, and
supervising all safety precautions and programs in connection with the
performance of the Contract. The Contractor shall take reasonable precautions
for safety of, and shall provide reasonable protection to prevent damage, injury
or loss to:

          .1   employees on the Work and other persons who may be affected
               thereby;

          .2   the Work and materials and equipment to be incorporated therein;
               and

          .3   other property at the site or adjacent thereto.

The Contractor shall give notices and comply with applicable laws, ordinances,
rules, regulations and lawful orders of public authorities bearing on safety of
persons and property and their protection from damage, injury or loss. The
Contractor shall promptly remedy damage and loss to property at the site caused
in whole or in part by the Contractor, a Subcontractor, a Sub-subcontractor, or
anyone directly or indirectly employed by any of them, or by anyone for whose
acts they may be liable and for which the Contractor is responsible under
Subparagraphs 21.1.2 and 21.1.3, except for damage or loss attributable to acts
or omissions of the Owner or Architect or by anyone for whose acts either of
them may be liable, and not attributable to the fault or negligence of the
Contractor. The foregoing obligations of the Contractor are in addition to the
Contractor's obligations under Paragraph 14.12.

21.2      The Contractor shall not be required to perform without consent any
Work relating to asbestos or polychlorinated biphenyl (PCB).

                                   ARTICLE 22
                                   INSURANCE

22.1      The Contractor shall purchase from and maintain in a company or
companies lawfully authorized to do business in the jurisdiction in which the
Project is located insurance for protection from claims under workers' or
workmen's compensation acts and other employee benefit acts which are
applicable, claims for damages because of bodily injury, including death, and
from claims for damages, other than to the Work itself, to property which may
arise out of or result from the Contractor's operations under the Contract,
whether such operations be by the Contractor or by a Subcontractor or any-one
directly or indirectly employed by any of them. This insurance shall be written
for not less than limits of liability specified in the Contract Documents or
required by law, whichever coverage is greater, and shall include contractual
liability insurance applicable to the Contractor's obligations under Paragraph
14.12. Certificates of such insurance shall be filed with the Owner prior to the
commencement of the Work.

22.2      The Owner shall be responsible for purchasing and maintaining the
Owner's usual liability insurance. Optionally, the Owner may purchase and
maintain other insurance for self-protection against claims which may arise from
operations under the Contract. The Contractor shall not be responsible for
purchasing and maintaining this optional Owner's liability insurance unless
specifically required by the Contract Documents.

22.3      Unless otherwise provided, the Owner shall purchase and maintain, in a
company or companies lawfully authorized to do business in the jurisdiction in
which the Project is located, property insurance upon the entire Work at the
site to the full insurable value thereof. The insurance shall be on an all-risk
policy form and shall include interests of the Owner, the Contractor,
Subcontractors and Sub-subcontractors in the Work and shall insure against the
perils of fire and extended coverage and physical loss or damage including,
without duplication of coverage, theft, vandalism and malicious mischief.

22.4      A loss insured under Owner's property insurance shall be adjusted with
the Owner and made payable to the Owner as fiduciary for the insureds, as their
interests may appear, subject to the requirements of any applicable mortgagee
clause.

22.5      The Owner shall file a copy of each policy with the Contractor before
an exposure to loss may occur. Each policy shall contain a provision that the
policy will not be cancelled or allowed to expire until at least 30 days' prior
written notice has been given to the Contractor.

22.6      The Owner and Contractor waive all rights against each other and the
Architect, Architect's consultants, separate contractors described in Article
17, if any, and any of their subcontractors, sub-subcontractors, agents and
employees, for damages caused by fire or other perils to the extent covered by
property insurance obtained pursuant to this Article 22 or other property
insurance applicable to the Work, except such rights as they may have to the
proceeds of such insurance held by the Owner as fiduciary. The Contractor shall
require similar waivers in favor of the Owner and the Contractor by
Subcontractors and Sub-subcontractors. The Owner shall require similar waivers
in favor of the Owner and Contractor by the Architect, Architect's consultants,
separate contractors described in Article 17, if any, and the subcontractors,
sub-subcontractors, agents and employees of any of them.

                                   ARTICLE 23
                               CORRECTION OF WORK

23.1      The Contractors shall promptly correct Work rejected by the Architect
or failing to conform to the requirements, of the

AIA DOCUMENT A117 . ABBREVIATED COST-PLUS OWNER-CONTRACTOR AGREEMENT . SECOND

AVENUE, N.W., WASHINGTON, D.C. 20006

11  A117-1987



Contract Documents, whether observed before or after Substantial Completion and
whether or not fabricated, installed or completed, and shall correct any Work
found to be not in accordance with the requirements of the Contract Documents
within a period of one year from the date of Substantial Completion of the
Contract or by terms of an applicable special warranty required by the Contract
Documents. The provisions of this Article 23 apply to Work done by
Subcontractors as well as to Work done by direct employees of the Contractor.

23.2      Nothing contained in this Article 23 shall be construed to establish a
period of limitation with respect to other obligations which the Contractor
might have under the Contract Documents. Establishment of the time period of one
year as described in Paragraph 23.1 relates only to the specific obligation of
the Contractor to correct the Work, and has no relationship to the time within
which the obligation to comply with the Contract Documents may be sought to be
enforced, nor to the time within which proceedings may be commenced to establish
the Contractor's liability with respect to the Contractor's obligations other
than specifically to correct the Work.

                                   ARTICLE 24
                             MISCELLANEOUS PROVISIONS

24.1      The Contract shall be governed by the law of the place where the
Project is located.

24.2      As between the Owner and the Contractor, any applicable statue of
limitations shall commence to run and any alleged cause of action shall be
deemed to have accrued:

          .1   not later than the date of Substantial Completion for acts or
               failures to act occurring prior to the relevant date of
               Substantial Completion;

          .2   not later than the date of issuance of the final Certificate for
               Payment for acts or failures to act occurring subsequent to the
               relevant date of Substantial Completion and prior to issuance of
               the final Certificate for Payment; and

          .3   not later than the date of the relevant act or failure to act by
               the Contractor for acts or failures to act occurring after the
               date of the final Certificate for Payment.

                                   ARTICLE 25
                           TERMINATION OF THE CONTRACT

25.1      If the Architect fails to recommend payment for a period of 30 days
through no fault of the Contractor, or if the Owner fails to make payment
thereon for a period of 30 days, the Contractor may, upon seven additional days'
written notice to the Owner and the Architect, terminate the Contract and
recover from the Owner payment for all Work executed and for proven loss with
respect to materials, equipment, tools, and construction equipment and
machinery, including reasonable overhead, profit and damages applicable to the
Project, provided that in no event shall such payment cause the Guaranteed
Maximum Price to be exceeded.

25.2      If the Contractor defaults or persistently fails or neglects to carry
out the Work in accordance with the Contract Documents or fails to perform a
provision of the Contract, the Owner, after seven days' written notice to the
Contractor and without prejudice to any other remedy the Owner may have, may
make good such deficiencies and may deduct the cost thereof, including
compensation for the Architect's services and expenses made necessary thereby,
form the payment then or thereafter due the Contractor. Alternatively, at the
Owner's option, and upon certification by the Architect that sufficient cause
exists to justify such action, the Owner may terminate the Contract and take
possession of the site and of all materials, equipment, tools, and construction
equipment and machinery thereon owned by the Contractor and may finish the Work
by whatever method the Owner may deem expedient. If the unpaid balance of the
Contract Sum exceeds costs of finishing the Work, including compensation for the
Architect's services and expenses made necessary thereby, such excess shall be
paid to the Contractor, but if such costs exceed such unpaid balance, the
Contractor shall pay the difference to the Owner, provided that in no event
shall such payment cause the Guaranteed Maximum Price, if any, to be exceeded.

26.1      The attached Development Budget (Exhibit B) is to be used as the basis
          for anticipated costs.

26.2      The Owner shall reimburse Contractor for any out-of-pocket expenses
          Contractor pays on the Owner's behalf relative to cost categories 18,
          19, 20, 21, 22 & 23 of the Development Budget.

26.3      This Agreement includes Work associated with the building shell and
          sitework.

26.4      It is agreed and understood that this Agreement excludes Work
          associated with tenant finish work. Documents for tenant finish work
          are expected to be complete and available for bidding on or about
          January 21, 2003. Cost associated with tenant finish work will be
          handled by way of a change order to this Agreement.
