                              ARCHITECT AGREEMENT

     THIS AGREEMENT (the "Agreement") is made and entered into as of the 19/th/
day of September, 2001 between WELLS OPERATING PARTNERSHIP, L.P (hereinafter
referred to as "Owner"), and HKS, INC., a Texas corporation (hereinafter
referred to as "Architect"), for the performance of architectural services in
connection with the design, development and interior finish of a three (3) story
mid-rise office building consisting of approximately two hundred sixty-eight
thousand two hundred ninety (268,290) gross square feet, together with parking
containing no fewer than one thousand fifty-six (1,056) parking spaces and
related improvements, to be located on a 14.8 acre site at 8900 Freeport Parkway
in Irving, Dallas County, Texas and currently intended to be referred to as The
Nissan Motor Acceptance Corporation project (the "Project").

     WHEREAS, Owner, without assuming, limiting or altering any of Architect's
duties, obligations or responsibilities, has engaged Champion Partners, Ltd. to
act as developer ("Developer") on behalf of Owner in connection with the
Project; and

     WHEREAS, Architect acknowledges the role of Developer as set forth herein
and agrees that Architect can and will perform in the manner contemplated by
this Agreement;

     WHEREAS, Developer has been engaged to act as the developer of the Project,
and in its capacity as the developer requires the services of an architectural
firm capable of providing professional design, architectural, engineering and
contract administration services of the highest quality; and

     WHEREAS, Architect agrees that it possesses the experience and expertise
necessary to provide such services and that it is capable meeting Owner's
requirements for the Project as set forth in this Agreement; and

     WHEREAS, Architect is willing to undertake performance of the services
described herein for the compensation set forth and to commence and complete
such services in accordance with the terms hereof; and

     WHEREAS, Owner, in reliance thereon is willing to award this Agreement to
Architect and to satisfy the obligations of Owner set forth herein;

     NOW, THEREFORE, in consideration of the agreements, obligations and
undertakings  herein contained, the Owner and the Architect agree as follows:

                                   ARTICLE 1
                   ARCHITECT'S SERVICES AND RESPONSIBILITIES

     1.1  Architect agrees to and shall perform all architectural and other
professional design services for the Project, including but not limited to the
Basic Services (as hereinafter

ARCHITECT AGREEMENT - Page 1
-------------------
<PAGE>

defined), and to the extent requested by Owner, the Additional Services set
forth in Article 3 hereof.

     1.2  Architect acknowledges that it is solely responsible for the design of
the Project and that neither the rights of Owner of approval nor the granting of
any approval shall be deemed to relieve Architect from such responsibility or
constitute a waiver by Owner of any claim arising out of Architect's failure to
meet such responsibility.  Architect further acknowledges that it has received
and reviewed the descriptions, requirements, considerations, objectives,
parameters, criteria and preliminary details of the Project (the "Design
Criteria") attached hereto and incorporated herein as Exhibit A, and that it
                                                      ---------
participated in the preparation, design and development of the Design Criteria
and is fully familiar with it.  Architect agrees that its design, drawings and
specifications for the Project shall conform with the Design Criteria; provided,
however, that nothing herein shall relieve Architect of responsibility for the
design of the Project, and provided further that no feature, item or detail
shown or provided for in the Design Criteria shall be deemed waived by Owner
merely by its approval of any design, drawing, specification or other documents
inconsistent with or failing to include features requested by the Design
Criteria, any such waiver to be accomplished only by an express written waiver
by Owner following request therefor by Architect. The foregoing shall not limit
Owner's right to require changes in the Project which vary from the criteria or
details of the Design Criteria; provided, however, any such changes shall be
pursuant to a written agreement or a directive from the Owner (or through its
Developer) then or contemporaneously therewith reduced to writing and approved
by or on behalf of Owner. Matters of routine coordination between consultants or
the contractors, when consistent with the Design Criteria or approved changes,
shall not constitute changes in the Project requiring the foregoing written
agreement or approval.

     1.3  Architect's Basic Services consist of all services falling within the
scope of the five phases described in Article 2 hereof. Basic Services shall
include, without limitation, all architectural, civil, structural, mechanical,
electrical, plumbing, interior design and engineering services necessary to
produce a complete and accurate set of construction documents, drawings and
specifications as described and required herein, and any other services included
under Article 16 as part of the Basic Services, all consistent with the Design
Criteria.  Architect's Basic Services include the interior tenant finish design
as well as that required for base building and building shell construction, and
requires Architect to provide all services of interior design necessary to allow
"turn-key" construction of the Project and occupancy by its tenant as required
by the Design Criteria set forth in Exhibit A.  No phase of the services shall
                                    ---------
begin until authorization has been given to Architect to proceed to the next
phase.

     1.4  Architect agrees that it and its employees, agents and consultants
have all the education, skills, knowledge, expertise and experience necessary to
perform all of the services required of the Architect under this Agreement, that
it is experienced in performing and providing such services on projects of the
type, size, scope and complexity of the Project, and that it is professionally
licensed and registered in the State of Texas, and meets and is in compliance
with all applicable professional and industry standards, practices and
requirements. Architect also agrees that it and its employees, agents and
consultants are thoroughly familiar with, and shall exercise professional
efforts to cause the Project to comply with, all applicable laws, codes,
ordinances, rules and regulations applicable to the design of the Project,
including without limitation the Americans with Disabilities Act and the Texas
Accessibility Standards in

ARCHITECT AGREEMENT - Page 1
-------------------
<PAGE>

accordance with the standard of care employed by reasonably prudent architects
providing similar services in connection with projects of similar scope in the
State of Texas. Architect shall at all times maintain on its staff and assign to
the Project sufficient, qualified personnel so that all required services are
performed within the time limits established hereunder, and for the sum set
forth herein. Architect shall submit to Owner a complete list of all personnel
and consultants assigned to the Project, including each person's Direct
Personnel Expense category (as hereinafter defined), and shall indicate thereon
the jobs, tasks or assignments for which they are primarily responsible.
Architect shall not remove, reassign, replace or make any other changes in the
personnel and consultants assigned to the Project without the prior written
consent of Owner. The foregoing notwithstanding, Owner shall have the right to,
at any time, require the Architect to remove, reassign or replace any personnel
or consultants whose assignment to the Project is objected to by Owner. All
services provided by, through or under Architect shall be performed in
accordance with the standards and quality of professional skill and care
applicable to nationally recognized architectural and/or engineering firms
providing services for projects of comparable size, quality, complexity and
value.

     1.5  Architect's services shall be performed as expeditiously as possible
consistent with the professional skill and care required hereunder and the
orderly progress of the Work. Architect shall be responsible for completion of
the various aspects and phases of its services within the applicable time limits
specified in Exhibit D hereto or elsewhere in this Agreement.  No later than ten
             ---------
(10) days after request from  Owner, Architect shall submit  a proposed schedule
for the performance of the various services, which shall comply with the
requirements of Exhibit D hereto.  Such schedule, as modified to the
                ---------
satisfaction of and approved by Owner and Architect, shall constitute the
"Project Schedule." The Project Schedule shall include, among other things, an
outline of the timing required to complete the various design phases through
issuance of the Contract Documents, allowances for all periods of time required
for all reviews and actions by the Developer, the Owner (as hereinafter defined)
and the lender, if any, and for preparation and approval of all submissions to
the governmental authorities having jurisdiction over the Project. The Project
Schedule shall be consistent with the time limits specified by the Owner or
otherwise set forth in Exhibit D hereto or elsewhere in this Agreement.
                       ---------

     1.6  Architect shall strictly adhere to the time limits established by the
Project Schedule. The Project Schedule shall be revised from time to time as
requested by Owner to take into account the current status and condition of the
Architect's services, construction activities and the Project; provided,
however, no adjustment in the specified time limits will be allowed without
Owner's prior written consent, except as provided below. Architect will provide
Owner with weekly progress reports in a form acceptable to Owner.

     1.7  Time is of the essence in this Agreement. The time limits specified in
this Agreement for completion of the various portions of the Architect's
services may be extended only if and to the extent that such limits cannot be
met because of unreasonable delays by the Developer and/or Owner in giving any
directions or taking any other actions required of the Developer or Owner
hereunder or because of other causes which Architect could not reasonably
anticipate, avoid or control and which are of an unusual and extreme nature. If
the Architect wishes to make a claim for an extension of any time limit, the
Architect must submit its claim in

ARCHITECT AGREEMENT - Page 3
-------------------
<PAGE>

writing to the Owner within seven (7) days after the event or cause forming the
basis for the claim first occurs or arises. In the event any such claim is not
submitted in the time and manner required, the Architect will be deemed to have
waived any right to an extension of time based on such event, cause or
occurrence, and will be required to meet the time limit in question. No
adjustment or extension of time shall be effective unless accepted in writing by
Owner.

     1.8  Before commencing its services, the Architect shall assemble all
necessary information and documents and shall perform all reviews, and request
any required inspections and test necessary, to properly prepare all documents
required under this Agreement.  All documents required herein shall be prepared
to the reasonable satisfaction of the Developer, the Owner and lender (if
applicable), and shall be in full compliance with the applicable requirements of
all governmental authorities having jurisdiction over the Project.  Architect
shall furnish the Owner with such copies of the documents and materials prepared
by the Architect during the various stages of the design and construction phases
as Owner shall request.

     1.9  Architect understands and acknowledges that Developer is not and will
not be the owner of the Project or of the property on which it is located.
Developer is acting only as Owner's developer for development and construction
of the Project.  Architect and Owner hereby acknowledge and agree that Developer
is intended to be and shall be a third party beneficiary to this Agreement, and
may enforce all of the rights, remedies and privileges of Owner hereunder.   It
is further understood and agreed that Owner and its Developer have certain
duties and obligations to Nissan Motor Acceptance Corporation, the intended
tenant of the Project.  Architect shall assist and cooperate with the Owner and
Developer in satisfying the requirements of the tenant and shall make such
presentations, attend such meetings and incorporate such modifications to the
design as may be requested to allow Developer and Owner to meet their respective
obligations, subject to the provisions hereof regarding Basic and Additional
Services.  Architect shall not, however, take instruction or direction from or
perform any Additional Services based on request from any person other than
Owner or its Developer, nor shall Architect be entitled to any additional cost
or extension of schedule in the event thereof.

                                   ARTICLE 2
                                BASIC SERVICES

     Architect's Basic Services shall consist of the Schematic Design Phase, the
Design Development Phase, the Construction Documents Phase, the Construction
Procurement Phase and the Construction Phase.  Architect shall promptly commence

hereto and the Project Schedule.  Architect shall be responsible for
completeness and accuracy of its services and shall correct all errors or
omissions at its own expense.  If the negligence or acts or omissions of
Architect result in a claim against Developer or Owner, Architect shall
indemnify and hold Developer and Owner harmless as provided herein.

ARCHITECT AGREEMENT - Page 7
-------------------
<PAGE>

     2.4  Construction Procurement Phase

          2.4.1  Architect shall assist Owner in soliciting and obtaining bids
or negotiated proposals and shall assist Owner in awarding and preparing
contracts for construction.

          2.4.2  Without limitation of the foregoing, the Architect shall:

                 (a)   issue bidding and proposal requirements to all potential
                       contractors;

                 (b)   receive and analyze any questions from contractors,
                       transmit such questions and the Architect's recommended
                       answers in writing to the Owner for response, and issue
                       any required addenda to the bidding and proposal
                       requirements; and

                 (c)   receive and analyze bids and proposals and make
                       recommendations in writing to the Owner as to the award
                       of the construction contract. Such recommendations shall
                       include detailed reasons for the Architect's
                       recommendations and a summary of the Architect's opinions
                       as to the positive and negative factors relating to each
                       bid and/or proposal.

          2.4.3  Whenever the scope of the Project contemplates alternate,
separate or sequential bids or proposals, or whenever Developer or Owner
purchased items are anticipated, a reasonable level of Architect's preparation
and assistance in obtaining bids or negotiating proposals in connection
therewith is included within the Architect's Basic Services.  In the event
extensive involvement beyond that which is normal and customary is required for
reasons unrelated to Architect, Architect may request Additional Services
therefor pursuant to the procedures set forth herein, which shall be subject to
Owner's prior approval.

completion of the Project and acceptance of the Project in full by the Owner.

          2.5.2  Architect shall provide administration of the contract for
construction as set forth below and set forth in the applicable provisions of
the General Conditions of the Construction Contract between the Owner and the
Contractor (a copy of the standard form of which is attached hereto as Exhibit

Owner. Architect hereby consents to Developer's assignment to Owner of its
entire interest in this Agreement contingent and effective only upon Owner's
written acceptance of such assignment, or in connection with a mortgage on, or
the sale or transfer of, the Project or any interest therein or any entity
holding title thereto; and effective from the date of such assignment, sublease
or transfer, Developer shall be released from all obligations to Architect
hereunder arising after the

ARCHITECT AGREEMENT - Page 19

date of such assignment, sublease or transfer, and Developer shall not be
required to pay Architect for any services in connection with the Project
rendered after the date of any such assignment, sublease or transfer.

     13.2 Architect understands and acknowledges that Owner may, at Owner's sole
option, choose to engage a general contractor for construction of the Project on
a design and build basis.  In such event, such general contractor shall, without
limiting Architect's obligations to the Owner, be responsible to Owner for
designing as well as constructing the Project.  Architect agrees that Owner may,
at any time, assign this Agreement to the general contractor engaged for
construction of the Project, and Architect hereby consents to such assignment
and agrees that in such event Architect shall perform its obligations hereunder
for the general contractor to the same extent as if this Agreement had been
originally entered into between such parties and shall look solely to such
general contractor for satisfaction of payments or claims hereunder or otherwise
in connection with the Project.  Specifically, Architect agrees to the
continuing use and development following such assignment of any and all design
documents prepared pursuant to this Agreement, and that such assignment shall
not result in any adjustment of Architect's compensation or time for
performance.  Architect further consents and agrees that upon the occurrence of
the assignment of this Agreement, Developer and Owner shall be released from any
and all obligations or liability to the Architect in connection with this
Agreement or the Project.

     13.3 Architect agrees that Developer (or Owner) may collaterally assign
this Agreement to the Lender(s) in connection with the financing of the Project,
and agrees to execute documents evidencing such collateral assignment and
consent as may be reasonably required.

                    GENERAL CONDITIONS OF THE CONTRACT FOR
                  THE DESIGN AND BUILD CONSTRUCTION AGREEMENT

                                   ARTICLE 1

                              CONTRACT DOCUMENTS
                              ------------------

1.1    DEFINITIONS
       -----------

1.1.1  THE CONTRACT DOCUMENTS
       ----------------------

       The Contract Documents consist of those documents identified on Exhibit B
                                                                       ---------
to the Design and Build Construction Agreement and as said Exhibit may be
amended from time to time.

       If there is any inconsistency or ambiguity in any of the Contract
Documents, the governing document will be as listed in Paragraph 1.3 of the
General Conditions.

       The Contract Documents includes the Advertisement or Invitation to Bid
and the Instructions to Bidders, but does not include the Design/Builder's Bid
or any other Bidding Documents, unless specifically enumerated in the Agreement.

1.1.2  THE CONTRACT
       ------------

       The Contract Documents form the Contract for Construction and are
sometimes referred to as the "Contract". The Contract represents the entire and
integrated agreement between the parties hereto and supersedes all prior
negotiations, representations, or agreements, either written or oral. Nothing
contained in the Contract Documents shall create any contractual relationship or
third party beneficiary relationship between the Developer or the Owner and any
Subcontractor or Sub-subcontractor or between any persons or entities other than
between the Owner and the Design/Builder.

1.1.3  THE WORK
       --------

       The Work comprises the completed construction required by the Contract
Documents and includes all labor, materials, equipment and supervision necessary
to produce the Project, functioning properly, including all items necessary or
appropriate to permit the proper and full utilization of the Project.

1.1.4  THE PROJECT
       -----------

       The Project is the total construction of which the Work performed under
the Contract Documents may be the whole or a part.

1.2    EXECUTION, CORRELATION, INTENT AND INTERPRETATIONS
       --------------------------------------------------

                                       1
<PAGE>

1.2.1  The intent of the Contract Documents is to include all items necessary
for the proper execution and completion of the Work by the Design/Builder.  The
Contract Documents are complementary, and what is required by one shall be as
binding as if required by all and performance by the Design/Builder shall be
consistent with the requirements of the Contract Documents and those matters
reasonably inferable from them as being necessary to produce the intended
results.

1.2.2  Organization of the Specifications into divisions, sections and articles,
and arrangement of Drawings shall not control the Design/Builder in dividing the
Work among Subcontractors or in establishing the extent of Work to be performed
by any trade.

1.2.3  Unless otherwise stated in the Contract Documents, words which have well-
known technical or construction industry meanings are used in the Contract
Documents in accordance with such recognized meanings.

1.2.4  By executing the Design and Build Construction Agreement Design/Builder
represents that:

       1. it has examined all Contract Documents and all Exhibits attached
          thereto, the Project Site, and the accessibility to and general
          character of said Site;

       2. the Contract Documents are complete, coordinated, and will allow for
          proper and timely construction of the Work;

       3. it has visited the Site, and has satisfied itself as to the nature of
          the Work, the conditions of any visible existing buildings, structures
          or features at the Site, the condition of the soil, the
          Specifications, the Drawings, the character of the equipment and
          facilities needed preliminary to and during the prosecution of the
          Work, the general and local conditions under which the Work is to be
          performed, the construction hazards, and all other matters witch could
          be reasonably ascertained and in any way affect the Work under the
          Contract Documents, and has correlated its observations with the
          requirements of the Contract Documents; and

       4. the Contract Sum for performance of the Contract includes any and all
          costs as required by the Contract Documents or as reasonably inferable
          therefrom as being necessary to completely construct and perform the
          Work under the above mentioned conditions.

1.2.5  Design/Builder understands and agrees that:

       1. If an item of Work is shown on the Drawings and not specified, or
          specified and not shown on the Drawings, or neither specified or shown
          but considered to be incidental to the Work and the accepted practice
          of the respective trade, or required for total completion of the Work
          and the Project, it shall be construed to

                                       2
<PAGE>

             be both shown and specified and shall be included in the scope of
             Work and within the Contract Sum.

         2.  Design/Builder shall complete all Work in accordance with the
             requirements of Contract Documents and make no change therefrom
             without having first received written authorization from Owner or
             its authorized representative. Where detailed information is
             lacking, before proceeding with Work, Design/Builder shall refer
             the matter to Developer for further information. Design/Builder
             shall be solely responsible for all extra cost and extra time for
             changes made to Work without having received prior written
             authorization from Owner or its authorized representative.

         3.  If Work is required in such a manner as to make it impossible to
             produce first-class Work, or should discrepancies appear among
             Contract Documents, Design/Builder shall request clarification from
             the Developer before proceeding with the affected part of the Work.
             If Design/Builder fails to obtain such clarification before
             proceeding with such portion of the Work, no excuse thereafter will
             be entertained for failure to carry out Work in satisfactory
             manner, and Design/Builder shall be solely responsible for all
             extra cost and time for proceeding with such Work without receiving
             clarification from Developer.

         4.  Mention herein or indication on the Drawings of articles,
             materials, or operations means that the Design/Builder shall
             provide each item mentioned or indicated of the quality noted,
             perform each operation prescribed according to conditions stated,
             and provide therefor all necessary labor, equipment and incidentals
             pertaining thereto.

         5.  Should conflict occur in or between Drawings and Specifications
             which is not clarified by the order of precedence specified herein,
             Design/Builder is deemed to have estimated on the more expensive of
             the various ways shown for doing the Work unless he shall have
             asked for and obtained written decision from the Developer as to
             which method or materials will be required.

         6.  The Work to be performed by Design/Builder shall conform with and
             satisfy the requirements of the Contract Documents, including
             without limitation the requirements of the Design and Build
             Construction Agreement.

1./2./6  Written interpretations necessary for the proper execution or progress
of the Work, in the form of Drawings or otherwise, will be issued by Developer
promptly after written request therefore by Design/Builder.  Design/Builder
shall make written request to Developer for such interpretations as soon as
possible after the need for such interpretations is identified by
Design/Builder.  Such interpretations shall be consistent with and reasonably
inferable from the Contract Documents.

1.2.7    Any discrepancies or omissions found in the Contract Documents by
Design/Builder shall be reported to Owner and Developer promptly and in all
events prior to proceeding with

                                       3
<PAGE>

any portion of the Work affected thereby. Developer will clarify discrepancies
or omissions in writing, promptly after written requests are received from the
Design/Builder. Failure by Design/Builder to request interpretations and/or
report discrepancies promptly after discovery and before incurring additional
expense as a result of any potential Contract Document deficiency will cause any
such additional costs to be included within the original Contract Sum.

1.2.8   Design/Builder's and Subcontractor's responsibility: Design/Builder and
Subcontractor(s) for all trades involved in the Project shall be responsible to
familiarize themselves with the Work of all other trades included in this
Project.  Each of the Subcontractors shall be responsible for all Work not only
shown or implied on the Drawings that pertain to the Subcontractor's Work, but
also his Work as shown on other trade drawings.  Design/Builder and
Subcontractors for all trades are, hereby cautioned to carefully study all
Drawings and Specifications including but not limited to architecture,
engineering, interior design, and consultants drawings, with the understanding
that any item of equipment or integral part of the Work or the Project requiring
plumbing, heating, venting and/or air conditioning (H.V.A.C.), or electrical
connections, shown on the Drawings or the Contract Documents, the corresponding
Design/Builder or Subcontractor is nevertheless responsible for the connection
of these items or parts to his particular service and has included all such
connections in his contract price.

1.2.9   Design/Builder is responsible for coordinating all Subcontractor bids
and work of all trades to ensure that all Work shown or specified is included in
the Contract Sum specified in the Agreement. Particular care is required in
Design/Builder's coordination of the H.V.A.C., plumbing, electrical, roofing and
fire protection and other trades 'with each other and with the other trades. In
no case will Developer arbitrate disputes over which trade is to furnish work.
In no case will Owner become liable for additional payments over and above the
Contract Sum specified in the Agreement due to failure of Design/Builder to
resolve any such disputes.

1.2.10  Should the Drawings disagree themselves, figures shall govern over
scaled measurements, large scaled Drawings shall govern over small scale
Drawings, the greater quantity of work or materials shall be furnished and
performed; the descriptive writings shall govern over legends indicating
material or conditions and the Agreement takes precedence over all other
Contract Documents.

1.2.11  The words "approved", "inspected", "directed", "selected", and similar
words and phrases shall be presumed to be followed by "by Owner".  The words
"satisfactory", "submitted", "reported", and similar words and phrases shall be
presumed to be followed by "to Owner".  Words like 'install", "provide",
"locate", "furnish", and "supply" shall be construed to include complete
furnishings and installation or construction.

1.2.12  In the interest of brevity the Contract Documents frequently omit
modifying words such as "all" and "any" and articles such as "the" and "an," but
the fact that a modifier or an article is absent from one statement and appears
in another is not intended to affect the interpretation of either statement.

1.3    ORDER OF PRECEDENCE
       -------------------

1.3.1  If there is any inconsistency or ambiguity in any of the Contract
Documents, the governing document will be that listed first below, except in the
case of any ambiguity or inconsistency within either the Drawings or

       --------

4.5.1  The Design/Builder warrants to the Owner that all materials and equipment
furnished under the Contract Document will be new unless otherwise specified,
and that all Work will be of good quality, free from faults and defects and in
conformance with the Contract Documents.  All Work not conforming to these
requirements, including substitutions not properly approved and authorized,
shall be considered defective.  If required by the Developer, the Design/Builder
shall furnish satisfactory evidence as to the kind and quality of materials and
equipment.  This warranty is not limited by the provisions of Paragraphs 4.5.2
through 4.5.5 and shall survive any expiration or termination of the Contract.
Warranty forms as described in the Specifications or elsewhere in the Contract
Documents shall be submitted to Developer for review and consent at the time of
the Subcontractors bids and prior to executing a contract with any
Subcontractor.  All warranties shall commence at initial occupancy following
final completion of the Work regardless of any temporary or permanent use of
equipment, products, or materials during construction or partial occupancy.
Signed warranties in form approved by Developer will be forwarded to Developer
at Substantial Completion.  At the time each warranty is delivered,
Design/Builder shall provide Developer with a list designating the persons or
officers who may be notified to fulfill any claim under such warranty.  Any
costs that may be associated with

manner in conformance with the Project schedule (as the same may be extended),
and in accordance with the Contract Documents and all laws, codes, ordinances,
rules and regulations; (ii) to cause all materials and all portions of the
Project to be readily available as and when required in connection with the
construction, furnishing and equipping of the Project; and (iii) to make or
cause to be made all repairs, removals or replacements arising out of any non-
conforming work or any defect in labor, workmanship, materials or equipment
employed, supplied or installed in the construction of the Project.  All such
repairs, removals or replacements shall be made at Design/Builder's sole cost
and expense.  The retention by Design/Builder of Subcontractors or Sub-
subcontractors and the delivery of any warranties by suppliers, manufacturers,
Subcontractors or Sub-subcontractors shall not in any way relieve Design/Builder
from any obligations hereunder.  Design/Builder shall obtain in the name of
Owner (or such party as Developer may designate) or give to Owner all other
warranties or guarantees specifically set forth in the Contract Documents.
Design/Builder shall bear the cost of making good all work of Owner, Developer
or separate contractors destroyed or damaged by such correction or removal.
Design/Builder also agrees to hold Owner and Developer harmless from liability
of any kind arising from damages due to said defects.  Design/Builder shall make
all repairs and replacements promptly upon receipt of written orders for same
from Owner.  If Design/Builder fails to immediately make the repairs and
replacements Owner may cause completion of the Work, and Design/Builder shall be
liable for all costs caused thereby, including but not limited to the costs of
time delays or the cost of additional services of architect(s) made necessary by
such failure.

4.5.3  If Owner deems it inexpedient to require the correction of Work damaged
or not performed in accordance with the Contract Documents, an equitable
deduction from the Contract Sum shall be made, by Change Order, by agreement
between Design/Builder and Owner.  Until such Change Order, Owner may withhold
such sums as are just and reasonable from monies, if any, due Design/Builder.

4.5.4  The Design/Builder's obligations under this Paragraph 4.5 shall survive
the expiration or termination of the Contract.

shall promptly notify the Developer in writing and any necessary changes shall
be made by the Design/Builder.  If the Design/Builder performs any Work knowing,
or when in the proper performance of its design and construction duties and
obligations he should have known it to be contrary to such laws, ordinances,
codes, rules and regulations, he shall assume full responsibility therefor and
shall bear all costs and expenses attributable thereto and shall indemnify and
hold the Developer harmless therefrom.

Documents.  If Design/Builder believes that notes on shop Drawings constitute a
change to the Contract Documents, it shall promptly notify Developer in writing
and shall not proceed with fabrication or installation until directed to do so
by Owner.  If Design/Builder proceeds with changes to the Contract Documents as
noted on Shop Drawings without first notifying Owner in writing and obtaining
Owner's prior written approval, Design/Builder shall be solely responsible for
all extra cost or time delays related to said changes.

4.11.13   If the Design/Builder shall alter any information on previously
submitted Shop Drawings besides the notations called for he must highlight by
"clouding" and note this new information to bring it to the Owner's attention.

4.11.14   Any review by Owner or Developer of any Shop Drawing and Material
Samples and related Schedules shall only be for conformance with the design
concept of the Project and for compliance with the information given in the
Contract Documents.  No review of such Schedules and Shop Drawings and/or
Material Samples shall relieve Design/Builder of responsibility for accuracy of
such Schedules, Shop Drawings and Material Samples, nor for proper fitting,
construction of work, design of portions of the Work (if applicable), furnishing
of materials or Work required by the Contract and not indicated on Shop
Drawings.  No reviews or approvals shall be construed as approving departures
from Contract requirements.

4.11.15   Design/Builder shall have copies of all approved Shop Drawings at the
site at all times and shall make them available to the Owner's representatives.

4.11.16   Design/Builder shall submit with such promptness as to cause no delay
in his own Work or in that of any other contractor, Samples as specified or
required.  Design/Builder shall not order materials until receipt of written
approval for same has been received from the Owner.  Any review or approval of
such Samples by or on behalf of Owner shall only be for conformance with the
design concept of the Work and for compliance with the information given in the
Contract Documents.  Design/Builder shall submit Samples to Owner of adequate
size, showing quality, type, color range, finish, texture and shall label same
with material name, quality, Design/Builder's name, date, Project name, other
pertinent data.  Once approved, Design/Builder will finish materials equal in
every respect to approved Samples.

4.11.17   Design/Builder shall keep approved Samples in a suitable place at the
site for use by the Design/Builder, Subcontractors and Sub-subcontractors,
Developer and their authorized representatives, to ensure that all Work is being
installed in accordance with the approved Samples.  All Samples become the
property of the Developer.

directions, Design/Builder shall submit copies of such directions with Samples
submitted to Owner for approval.

4.11.19   If requested by Owner, Design/Builder shall construct a mock-up
section of the exterior facade and other portions of the Project as shown by the
Contract Documents and when indicated on the Project Schedule.  The cost for
this facade and other mock-up sections, and the following touch-up and repair of
same, are to be included within the Contract Sum as an Allowance.  The
Design/Builder shall be responsible for all impacts made by constructing these
items or other mock ups or models required by the Contract Documents out of
normal sequence.

Design/Builder shall be agreed upon with Owner and clearly designated, and
trespass and encroachment on reserved space shall not be made. Any damage to
space allowed for use shall be repaired by Design/Builder at his expense on
release of the space. Design/Builder shall, prior to moving its forces on to the
Site, submit to Developer for its approval a diagrammatic plan indicating the
intended location of Design/Builder's and any Subcontractor's or Sub-
subcontractor's job trailers, temporary office(s), storage areas, staging areas,
parking and other similar construction facilities. All such locations shall be
subject to Owner's prior written approval and once approved shall not be
relocated without Developer's prior written approval.

4.12.3    Design/Builder shall provide and make available to Owner for use by
Developer's Representative, office space and related furniture, fixtures,
facilities, filing cabinets, and phones, at the site within the Design/Builder's
Project office.  Such space shall be available to Developer's Representative on
a full-time basis during the process of the Work until Final Completion, and
shall be comparable to that afforded Design/Builder's own Project Manager, and
shall be at no cost or expense to Owner or Developer, the cost thereof being
included in the Contract Sum.

                                SUBCONTRACTORS
                                --------------

5.1       DEFINITION
          ----------

5.1.1     "Subcontractor" is a person or organization who has a direct contract
with the Design/Builder to perform any of the Work at the Project site.  The
term Subcontractor is referred to throughout the Contract Documents as if
singular in number and masculine in gender and means a subcontractor or his
authorized representative.

5.1.2     "Sub-subcontractor" is a person or organization who has a direct or
indirect contract with a Subcontractor to perform any of the Work at the Project
site.  The term Sub-subcontractor is referred to throughout the Contract
Documents as if singular in number and masculine in gender and means a Sub-
subcontractor or an authorized representative thereof

5.1.3     Nothing contained in the Contract Documents shall create any
contractual relationship between the Owner or Developer and any Subcontractor or
Sub-subcontractor.

5.1.4     Design/Builder shall be responsible to Developer for acts and
omissions of its own employees and agents and of Subcontractors and Sub-
subcontractors and suppliers of all tiers and their employees and agents.
Design/Builder shall also be responsible for the coordination of its Work and
the Work of all Subcontractors and Sub-subcontractors, including, but not
limited to, all suppliers and materialmen.

5.1.5     If any part of Design/Builder's or Subcontractor's Work depends for
proper execution or results upon the Work of any other separate contractor or
Subcontractor, the  Design/Builder or Subcontractor shall inspect and promptly
report to the Developer any apparent discrepancies or defects in such Work that
render it unsuitable for such proper execution and results.  Failure of
Design/Builder or Subcontractor to so inspect and report shall constitute an
acceptance by Design/Builder and Subcontractor of the other contractor's work as
fit and proper to receive his Work, except as to defects which may develop in
the other separate contractor's Work after the execution of Design/Builder's or
Subcontractor's Work.

5.1.6     Should Design/Builder or a Subcontractor or Sub-subcontractor cause
damage to the Work or property of any separate contractor on the Project, the
Design/Builder shall, upon due notice, settle with such other contractor, if he
will so settle.  If such separate contractor makes a

                                      19
<PAGE>

claim against or sues the Developer or the Owner on account of any damage
alleged to have been so sustained, the Developer may notify the Design/Builder
who shall, if requested by Developer, defend such proceedings at
Design/Builder's expense, or Developer may, at Design/Builder's expense, engage
its own defense, and if any judgment or award against the Developer or the Owner
arises therefrom the Design/Builder shall pay or satisfy it and shall indemnify
and reimburse the Developer and Owner for all attorneys' fees, court costs, and
all other costs, fees, losses, damages or expenses which they have incurred or
suffered as a result of same.

5.2       AWARD OF SUBCONTRACTS AND OTHER CONTRACTS FOR PORTIONS OF THE WORK

in all events within five (5) days thereof, furnish to the Owner in writing, a
list of the names of qualified Subcontractors proposed for the Work for review
and approval by Owner. Should it become necessary to alter the list of approved
Subcontractors, Design/Builder shall submit proposed revisions to the Owner for
review and approval. Failure of the Owner to make objection to any qualified
Subcontractor so proposed by Design/Builder within a reasonable period of time
shall constitute acceptance of such Subcontractor, but only for the limited
purpose of permitting Design/Builder to engage such party.

5.2.2     The Design/Builder shall not contract with any Subcontractor or any
person or organization (including those who are to furnish materials or
equipment fabricated to a special design) proposed for portions of the Work
against whom Owner or Developer makes any reasonable objection.  The
Design/]Builder will not be required to contract with any Subcontractor or
person or organization against whom he has a reasonable objection.
Design/Builder shall furnish copies of all subcontracts entered into in
connection with the Work immediately following the execution thereof.

Subcontractor or person or organization who has been accepted by the Developer
unless the substitution is acceptable to the Owner and Developer.

5.2.4     Prior to entering into a contract with any Subcontractor in connection
with the Project, Design/Builder shall submit to Developer for its review
Design/Builder's forms of subcontract and purchase order which will be used by
Design/Builder.  Developer shall promptly review such documents and advise
Design/Builder of any modifications thereto required by Owner or Developer.
Design/Builder shall not engage any Subcontractor for the Work except by
subcontracts or purchase orders which are acceptable to Developer.  Not later
than one (1) month prior to each Subcontractor's first payment request, the
Design/Builder shall submit to the Developer copies of the executed subcontract
with all exhibits, a schedule of values to be consented to by Owner, copies of
required insurances, and copies of bonds as they may apply.  Such information is
required by Developer prior to and as a condition precedent to any payment to
Design/Builder with respect to such Subcontractor.

5.2.5     Design/Builder shall furnish to Developer monthly with his Application
for Payment a correct and current list of all Subcontractors and Sub-
subcontractors employed in connection

                                      20

               acceptable to Owner under each subcontract to which the
               Design/Builder is a party, in reasonable time to enable the
               Design/Builder to apply for payment in accordance with the terms
               hereof;

          4.   require that all claims for additional costs or extensions of
               time, with respect to subcontracted portions of the Work shall be
               submitted to the Design/Builder in sufficient time so that the
               Design/Builder may comply in the manner provided in the Contract
               Documents for like claims, if any, by the Design/Builder upon the
               Owner;

          5.   waive all rights the contracting parties may have against one
               another for damages caused by fire or other perils covered by
               applicable property insurance, except such rights as they may
               have to the proceeds of such insurance held by the Owner as
               trustee;

          6.   require each Subcontractor to repair, at his expense, any damage
               to the Work or materials or supplies of other Subcontractors or
               any separate contractor engaged by Owner;

          7.   require each Subcontractor and Sub-subcontractor to agree to a
               provision indemnifying Developer and Owner to the extent
               attributable to the Work to be performed by them or by persons or
               entities for whom they are liable or responsible in all material
               respects equal and comparable to Design/Builder's obligations of
               indemnity under the Contract Documents; and

          8.   obligate each Subcontractor specifically to consent to the
               provisions of these General Conditions, including without
               limitation those of this Paragraph 5.3 and those permitting Owner
               to terminate Design/Builder's performance of the Agreement and/or
               to accept assignment of subcontracts and purchase orders.

approvals required by this Paragraph 7.7, Developer or Owner may do so with or
without notice to the Design/Builder.

7.7.5   Neither the observations by the Developer or Owner nor inspections,
tests or approvals by persons other than the Design/Builder shall relieve the
Design/Builder from his obligations to perform the Work in accordance with the
Contract Documents.

7.7.6   The Owner may conduct and pay for other testing as deemed necessary or
appropriate in Owner's sole discretion.

7.7.7   All other testing required by the Contract Documents shall be the

8.1    DEFINITIONS AND SUBSTANTIAL COMPLETION
       --------------------------------------

8.1.1  The "Contract Time" is the period of time allotted in the Contract
Documents for Substantial Completion of the Work.

8.1.2  The date of commencement of the Work is the date of the Agreement unless
otherwise established in a "Notice to Proceed" issued by the Owner to the
Design/Builder.

8.1.3  The terms "Substantial Completion" of the Work or the date the Work is
"Substantially Completed" or "Substantially Complete" shall mean performance of
all Work (exclusive of minor items of unfamiliar work that do not preclude
beneficial use and occupancy of the premises), together with such additional
items as may be specified therefor in Section VI of the Agreement or elsewhere
in the Contract Documents.

8.1.4  The term "day" as used in the Contract Documents shall mean calendar day.

8.1.5  In the event Owner determines that installation of all or part of the
trees, shrubs, grass, ground cover, flowers, foliage or other landscaping
required under the Contract Documents (the "Landscaping") should not be
performed or completed prior to Substantial Completion due to weather conditions
or otherwise, Developer may at its sole option and discretion recognize
Substantial Completion without completion of such portion of the Landscape as
designated to Design/Builder by Owner in writing. In such event, Landscaping
shall be completed as soon after Substantial Completion as possible and as
weather conditions permit, but in all events within ninety (90) days after
Substantial Completion unless otherwise agreed by Owner in writing. It is
understood and agreed that the foregoing determinations with regards to
Landscaping are for the benefit of Owner and are exercisable solely by Owner and
shall not give rise to any right or claim to extension of the Contract Time or
increase in the Contract Sum by Design/Builder or any Subcontractor or
Sub-subcontractor or other person or party performing all or any part of the
Work or the Landscaping.

8.2    PROGRESS AND COMPLETION
       -----------------------

8.2.1  All time limits stated in the Contract Documents are of the essence of
the Contract.

8.2.2  The Design/Builder shall begin the Work on the date of commencement as
defined in subparagraph 8.1.2. He shall carry the Work forward expeditiously
with adequate forces and shall achieve Substantial Completion within the
Contract Time.

8.2.3  Design/Builder shall take all steps necessary to ascertain the nature and
location of the Work, and the general and local conditions which can affect the
Work or the cost thereof. Any failure by Design/Builder to do so will not
relieve it from responsibility for successfully performing the Work without
additional expense to Owner. Owner assumes no responsibility for any
understanding or representation concerning conditions made by any of its
officers or agents

                                      26
<PAGE>

other person or party, including without limitation, environmental or weather
conditions in the area of the Project, unless such understanding and/or
representation by Developer is expressly stated in the Contract Documents.

8.2.4  Unless a contrary interpretation is clearly expressed, if a date or time
of completion is included in the Agreement, it shall be the date of Substantial
Completion as defined in Subparagraph 8.1.3, including authorized written
extensions thereto.

8.3    DELAYS AND EXTENSIONS OF TIME
       -----------------------------

8.3.1  It is understood and agreed that Owner and Design/Builder have
specifically considered and negotiated rights and responsibilities with respect
to events and occurrences which could delay or disrupt timely completion of the
Work.  The agreement of the parties is set forth in Section VI - Time for
Performance - of the Agreement, and the provisions thereof shall govern and
control over any inconsistent or conflicting provisions set forth in any other
Contract Document or elsewhere.

amount payable to the Design/Builder for the performance of the Work under the
Contract Documents, subject to increases or decreases thereto based upon
approved Change Orders.

9.2    SCHEDULE OF VALUES
       ------------------

9.2.1  Prior to submitting its first Application for Payment the Design/Builder
shall prepare and submit to the Developer and Owner the Schedule of Values
indicating costs of the various portions of the Work aggregating the total
Contract Sum divided so as to facilitate payments to subcontractors, prepared in
such form as specified by Owner and supported by such data to substantiate its
correctness as the Owner may require.  This Schedule of Values shall be subject
to the review and approval of Owner and Developer and as agreed to by the
Developer, shall be used as a basis for the Design/Builder's Applications for
Payment.

9.2.2  From time to time, the Design/Builder may need to revise certain portions
of the Schedule of Values to reflect change order amounts or other adjustments
permitted by the Agreement.  The Design/Builder shall prepare a revised Schedule
of Values indicating proposed revisions for Developer's review and approval.
Only following such approval shall Design/Builder utilize the revised Schedule
of Values for the purposes of Applications for Payment.

the Design and Build Construction Agreement a complete, notarized Application
for Payment, supported by the following documentation in a form acceptable to
the Owner:

       (1)  A waiver and release of lien in form and substance acceptable to
            Owner, by the Design/Builder, all Subcontractors and all Sub-
            subcontractors and suppliers who furnish labor, services, equipment
            or materials in connection with the construction of Project during
            the period covered by the Application for Payment and all past
            periods, as may be required to assure an effective waiver and
            release of mechanics' liens under the laws of the state in which the
            Project is located; and

       (2)  Copies of other appropriate documentation to substantiate each
            payment request requested by Owner or Developer or required by
            Owner's lender or title insurer.

       Developer and Owner and their designees shall have the right to review
and audit all of Design/Builder's books and records relating to the Project (and
to make copies thereof) from time to time upon not less than twenty-four (24)
hours notice. Design/Builder shall keep its books and records in an organized
condition in the State and County in which the Project is located.

9.3.2  Design/Builder shall bear the risk of physical loss or damage to any and
all materials, equipment and portions of the Work, whether at the site or stored
off-site.  Neither Owner nor Developer shall not be responsible for, and
Design/Builder agrees to protect the Work, materials, tools and equipment
against loss or damage by fire, theft, or accident and not to make any claim or
demand upon Owner or Developer for injury, loss or damage to Design/Builder, his
agents or employees for his Work, materials, tools or equipment, or on account
of any act or omission of Developer or any third person or persons.

9.3.3  The Design/Builder warrants and guarantees that all Work, materials and
equipment covered by an Application for Payment are incorporated in the Work and
that title will pass to the Owner (or such party as Owner may designate) upon
the earlier of incorporation into the Work or receipt of such payment by the
Design/Builder, free and clear of all liens, claims, security interests or
encumbrances, and that no Work, materials or equipment covered by an Application
for Payment will have been acquired by the Design/Builder or by any other person
performing the Work at the Site or furnishing materials and equipment for the
Project subject to an agreement under which an interest therein or an
encumbrance thereon is retained by the seller or otherwise imposed.
Additionally Design/Builder shall secure from any Subcontractor, Sub-
subcontractor or other supplier of materials and/or labor prior to making
payment to him, a notarized statement to the effect that said Subcontractor,
Sub-subcontractor or other supplier of materials, or labor, warrants and
represents that the lien waiver and release to be submitted in connection with
any Application for Payment covers all supplies, materials and labor utilized by
said Subcontractor, Sub-contractor or supplier in performing his Work and that
such representation is made to secure payment from Design/Builder and that
Design/Builder has relied thereon in making the payment requested.

                                      28

Agreement regarding payments, payments shall be paid to Design/Builder not later
than the date set forth therefor in the Design and Build Construction Agreement.

9.4.2  The Design/Builder shall promptly pay each Subcontractor, upon receipt of
payment from the Owner, out of the amount paid to the Design/Builder on account
of such Subcontractor's work, the amount to which said Subcontractor is entitled
as shown by the approved Subcontractor's application and Schedule of Values,
reflecting the percentage actually retained, if any, from payments to the
Design/Builder on account of such Subcontractor's work.  The Design/Builder
shall, by an appropriate agreement with each Subcontractor, require each
Subcontractor to make payments to his Sub-subcontractors in similar manner.

9.5    PAYMENTS WITHHELD
       -----------------

9.5.1  The Owner may withhold payment to the extent reasonably necessary to
protect the Owner as provided in the Contract Documents.  Developer may withhold
payment or, because of subsequently discovered evidence or subsequent
inspections, it may nullify the whole or any part of any payment previously
issued to such extent as it deems in good faith necessary to avoid damage or
loss on account of the Design/Builder's failure to adhere to the requirements of
the Contract Documents or to satisfy its obligations thereunder.

9.6    FAILURE OF PAYMENT
       ------------------

9.6.1  If the Owner should fail to approve any Application for Payment, through
no fault of the Design/Builder, with reasonable promptness after receipt of the
Design/Builder's Application for Payment, or if the Design/Builder is not paid
any amount owed to it hereunder, then the Design/Builder may, upon fifteen (15)
additional days written notice to the Owner, stop the Work until payment of the
amount owing has been received except for instances where the provisions of
Subparagraph 9.5.1 apply.

9.7    OCCUPANCY
       ---------

9.7.1  Developer or the Owner or any lessee or purchaser may utilize portions of
the Project prior to Substantial Completion of the Work as shown on the Project

<PAGE>

9.7.2  Based upon the Project Schedule, Owner shall schedule delivery of
furniture, fixtures and equipment for the Project.  Design/Builder acknowledges
and agrees that Design/Builder's failure to comply with the requirements
identified in the Project Schedule may result in cost increases to Developer or
the Owner or any lessee or purchaser for furniture, fixtures and equipment,
warehousing, installation, pre-opening costs and capital costs for the Project.
Design/Builder agrees to reimburse Developer for any such additional costs
incurred by Developer or the Owner or any lessee or purchaser resulting from
Design/Builder's failure to comply with the requirements identified in the
Project Schedule by deductive Change Order.

9.7.3  When the Design/Builder considers the Work to be Substantially Complete,
Design/Builder shall notify Developer in order that Developer and Design/Builder
may review the Work.  Developer will promptly review the Work and shall compile
and issue to Design/Builder a list of items to be completed or corrected (the
"Punch List Work").  The Design/Builder will complete all outstanding items
within thirty (30) days.  Failure to include any item(s) as Punch List Work
shall not alter the responsibility of Design/Builder to complete all Work in
accordance with the Contract Documents.

9.7.4  Owner shall be provided full occupancy of the Work (or any designated
portion thereof) upon issuance of a Certificate of Occupancy from the
appropriate governing authorities.  Such access and/or occupancy shall not be
deemed an acceptance of the Work not completed in accordance with the Contract
Documents, nor shall it prejudice Owner's right to reject unsatisfactory Work or
to withhold acceptance until directed corrective Work is completed by the
Design/Builder.

9.7.5  Owner (or such party as Owner may designate) shall assume responsibility
for providing heat, utilities and operation and maintenance of mechanical and
electrical systems (including controls) of the Project at the time of
Substantial Completion and Owner's (or such party as Owner may designate)
personnel shall have received the manufacturer's written brochures, catalog
cuts, maintenance instructions, training and such other information designated
by the Specifications.  Punch List Work shall be completed no later than thirty
(30) days following the date of Substantial Completion.

9.8    FINAL COMPLETION AND FINAL PAYMENT
       ----------------------------------

9.8.1  Upon receipt of written notice from Design/Builder that in its opinion
the Work is ready for final inspection and Final Acceptance, and upon receipt of
a final Application for Payment, Owner will promptly make such inspection and,
when they find the Work acceptable under the Contract Documents and the Contract
fully performed, Owner will thereafter issue a final progress payment within the
time provided in the Design and Build Construction Agreement (herein referred to
as the "Final Payment").  If Owner shall determine that the Punch List Work is
not completed, Design/Builder agrees to reimburse Owner for any reinspection
costs incurred.  Reimbursement shall be accomplished by a deductive Change Order
to the Contract Sum, or by payment from Design/Builder.

9.8.2  Final Payment shall not become due until the Design/Builder submits to
the Owner (1) an affidavit, in form and substance acceptable to Owner, that all
payrolls, bills for materials,

                                      30

<PAGE>

supplies and equipment, and other indebtedness connected with the Work for which
the Design/Builder, Owner or Developer's or Owner's property might in any way be
responsible, have been paid or otherwise satisfied by Design/Builder; (2) all
items required under Paragraph 9.3; (3) consent of surety, if any, to Final
Payment; and (4), any other material required by the Contract Documents or
reasonably requested by Owner, its lender or title insurer. If any Subcontractor
or Sub-subcontractor refuses a release or waiver required by the Owner, the
Design/Builder shall if requested by Owner furnish a bond satisfactory to the
Owner to indemnify against any such lien or claim, and if any such lien remains
unsatisfied after all payments are made, the Design/Builder shall refund to the
Owner all moneys that the Developer or Owner may be compelled to pay in
discharging such lien, including all costs and reasonable attorneys' fees.

9.8.2   Acceptance of Final Payment by the Design/Builder, a Subcontractor, Sub-
subcontractor or material supplier shall constitute a waiver of claims by that
payee except those previously made in writing and delivered to the party against
whom such claim is made and identified by that payee as unsettled at the time of
final Application for Payment.

severability of interest clause which provides that the insurance applies
separately to each insured and the following words verbatim: Owner is interested
in the maintenance of this insurance and it is agreed that this insurance will
not be canceled, materially changed or not renewed without at least thirty (30)
days advance written notice to Owner by Certified Mail, Return Receipt
Requested.

11.1.3  Certificates of Insurance acceptable to the Developer shall be filed
with the Owner prior to commencement of the Work.  Said Certificates shall name
Owner and such other parties, if any, as Developer may designate, as an
additional named insured against all claims under the specified policies.  These
Certificates shall contain a provision that coverages afforded under the

                                      34
<PAGE>

policies will not be canceled or materially changed or not renewed until at
least thirty (30) days prior written notice has been given to the Owner and such
additional party(ies) as Developer may designate by Certified Mail, Return
Receipt Requested.  All insurance required to be maintained by Design/Builder
and any Subcontractor or Sub-subcontractor shall be primary insurance and any
insurance maintained by Owner will apply as excess over all other insurance,
whether designated as primary, Umbrella, excess or excess/umbrella.  In no event
shall any failure of Owner to receive Certificates of Insurance required
hereunder or to demand receipt of such Certificates prior to Design/Builder
commencing the Work be construed as a waiver by Developer of Design/Builder's
obligations to obtain insurance pursuant to the Contract Documents.  The
obligation to procure and maintain any insurance required by the Contract
Documents is a separate responsibility of Design/Builder and independent of the
duty to furnish Certificates of such Insurance policies.

11.2    OTHER INSURANCE REQUIREMENTS
        ----------------------------

11.2.1  The Owner and the Developer shall be included as additional named
insureds under the Commercial General Liability Insurance and the "Umbrella"
excess liability coverage as set forth in Subparagraphs 11.1.1(B) and (C) above.

11.3    PROPERTY INSURANCE
        ------------------

11.3.1  Design/Builder shall purchase and maintain property insurance upon the
entire Work at the Site to the full insurable value thereof less a deductible in
an amount permitted by Owner.  This insurance shall include as insureds or
additional insureds the interests of the Owner, the Design/Builder,
Subcontractors and Subsubcontractors, in the Work and shall insure against the
perils of Fire, Extended Coverage, and shall be an "All-Risk" type of policy to
insure against physical loss or damage from perils generally covered by a
"Difference in Condition" policy, such as flood, earthquake, theft, builders
risk and such other perils which are usually not included in a simple Fire and
Extended Coverage Policy.  Design/Builder will be fully responsible for the
inclusion of all Subcontractors and Sub-subcontractors who should be insured
under this policy and Owner will not assume any financial responsibility caused
by failure of Design/Builder to so insure.

11.3.2  Any insured loss is to be adjusted with the Developer and made payable
to the Owner as trustee for the insureds, as its interests may appear, subject
to the requirements of any applicable mortgage clause and of Subparagraph
11.3.7.

11.3.3  The Owner and Design/Builder waive all rights against each other for
damages caused by fire or other perils to the extent covered by insurance
provided under this Paragraph 11.3 except such rights as they may have to the
proceeds of such insurance held by the Owner as trustee.  The Design/Builder
shall require similar waivers by Subcontractors and Subsubcontractors.  It is
understood that losses due to the negligence of Design/Builder, any
Subcontractor, Sub-subcontractor or anyone directly or indirectly employed by
any of them or for whose acts any of them may be liable or responsible or which
are not covered by Owner's property insurance or which are under the deductible
are the responsibility of the Design/Builder.

                                      35
<PAGE>

11.3.4  The Owner as depository shall, upon the occurrence of an insured loss,
deposit in a separate account any money so received, and Owner shall distribute
it in accordance with such agreement as the entities in interest may reach.

11.3.5  Should all or any part of the Work or construction covered by this
Contract be damaged or destroyed by any of the perils covered by the All-Risk
Builder's Risk Property Insurance specified in Paragraph 11.3 before final
completion of said Work, the Design/Builder, upon written instructions from the
Owner, shall proceed to replace and repair and complete said Work, in accordance
with original approved Drawings and Specifications to the extent said Work is
covered by the proceeds of various insurance policies.  In this event, the
provisions of the Contract Documents shall remain in full force and effect
except that the Contract Sum and the Contract Time shall be increased by the
total cost and additional time agreed upon by Owner and Design/Builder for
removing and replacing all of the damaged and destroyed Work.  The Owner,
however, at its option in the event of damage or destruction to the Work by any
of the aforementioned causes, may give written notice to the Design/Builder
declaring its desire to terminate Design/Builder's performance of the Contract
and after paying or adjusting all of the accounts charged to the Work in
accordance with the Contract, may terminate Design/Builder's performance of the
Contract.

11.3.6  Notwithstanding anything to the contrary, Owner shall not be deemed to
be either a custodian, bailee, nor insurer or in any other capacity or manner
responsible for any supplies, tools or equipment used by Design/Builder or any
Subcontractor or Sub-subcontractor in connection with the Work which may be left
at the Site by Design/Builder or any Subcontractor or any Sub-subcontractor; it
being expressly understood and agreed that Design/Builder and any Subcontractor
or Sub-subcontractor shall be solely responsible for securing, maintaining and
insuring all such supplies, tools or equipment whether the same be owned or
leased by Design/Builder, Subcontractor, Sub-subcontractor or by any other third
party providing labor or materials to the Work, the Project or the Site.

11.3.7  The Owner as trustee shall have power to reasonably and fairly adjust
and settle any loss with the insurers.

11.4    LOSS OF USE INSURANCE
        ---------------------

11.4.1  The Owner, at his option, may purchase and maintain such insurance as
will insure
against loss of use of its property, including, but not limited to, loss of
income, additional interim interest expense, insurance premiums.

11.5    SUBCONTRACTORS' INSURANCE
        -------------------------

11.5.1  The following forms of insurance are required to be furnished by all
Subcontractors and Sub-subcontractors:

        (1)  Workers' Compensation Insurance to cover full liability under
             workers' compensation Laws of the State where the Work is performed
             and employer's liability coverage with minimum occurrence/aggregate
             limits of $500,000.

                                      36
<PAGE>

     (2)  Commercial general liability insurance with coverage on an
          "occurrence" basis and insuring Subcontractors and Sub-subcontractors
          for Work performed under the Contract against claims for bodily
          injury, including death of any person other than Subcontractors'
          employees, and property damage for injury to or destruction of
          tangible property, other than the Work itself.  The policy shall
          contain the personal injury and broad form property damage
          endorsements modified as set forth below, and the policy shall be
          endorsed to remove any property damage liability exclusions pertaining
          to loss by explosion, collapse or underground damage.  These policies
          shall name Owner and such other party(ies), if any, as Owner may
          designate, as an additional insured as respects liability arising out
          of operations performed by or on behalf of the named insured.  The
          policy shall include coverage for:

     a)   Completed operations liability.

     b)   Design/Builders protective liability to cover Subcontractors'
          liability arising out of work performed by its Sub subcontractors.

     c)   Blanket contractual liability insuring the indemnification agreement
          contained in a subcontract.

     d)   Personal injury liability with employee exclusion deleted.

     e)   Broad form property damage extended to apply to completed operations.

     f)   Automobile liability insuring Subcontractors for operations of all
          owned, hired and non-owned vehicles.

     g)   The limits of liability shall not be less than:

          (i)     Bodily injury, except automobile

                  $5,000,000 each occurrence
                  $5,000,000 aggregate Completed Operations

          (ii)    Property damage, except automobile

                  $5,000,000 each occurrence
                  $5,000,000 aggregate

          (iii)   Bodily injury, automobile

                  $2,000,000 each person
                  $2,000,000 each occurrence

                                      37
<PAGE>

          (iv)    Property damage, automobile

                  $2,000,000 each occurrence

Either Design/Builder or Owner, however, has the option to require higher limits
of liability from designated Subcontractors or Sub-subcontractors.

        Certificates of Insurance shall be filed with the Design/Builder and
copied to Owner prior to commencement of Subcontractors' and Sub-subcontractors'
work. The requirements of Paragraphs 11.1.2.1 and 11.1.3 shall apply to the
insurance obligations of Subcontractors and Sub-subcontractors.

11.6    TRANSITION INSURANCE
        --------------------

11.6.1  When the Work is Substantially Complete, and Owner has accepted the
Work, Owner, at his option, may purchase and maintain such insurance as will
insure him against loss of the Work due to fire or other hazards, however
caused.

11.6.2  Until such time as Design/Builder has received Final Payment from Owner,
said insurance purchased and maintained by Owner under Subparagraph 11.6.1 shall
insure the interests of Owner, the Design/Builder, its Subcontractors and Sub-
subcontractors.  The carrier providing this insurance shall endorse the policy
waiving carrier's right of recovery from Owner, the Design/Builder, its
Subcontractors and Sub-subcontractors until such time as the Design/Builder and
all subcontractors have been paid in full.

                                  ARTICLE 12

                              CHANGES IN THE WORK
                              -------------------

12.1    CHANGE ORDERS
        -------------

        The provisions of this Article 12 are subject to and governed by those
of the Design and Build Construction Agreement with respect to Changes in the
Work.

12.1.1  The Owner, without invalidating the Contract and without notice to
sureties, may order Changes in the Work, within the general scope of the
Contract consisting of additions, deletions or other revisions, the Contract Sum
and the Contract Time being adjusted accordingly.  All such Changes in the Work
shall be authorized by Change Order, and shall be executed under the applicable
conditions of the Contract Documents.

12.1.2  A "Change Order" is a written order to the Design/Builder signed by the
Owner, issued after the execution of the Contract, authorizing a Change in the
Work or an adjustment in the Contract Sum or the Contract Time.  A Change Order
shall also be signed by the Design/Builder if he agrees to the adjustment in the
Contract Sum or the Contract Time.  The Contract Sum and the Contract Time may
be changed only by Change Order.  For changes in the Work the Design/Builder
shall submit to the Developer an itemized breakdown of the estimated costs for

                                      38
<PAGE>

Developer's review and approval.  The breakdown must show (i) all materials by
quantity and price, (ii) all labor by unit price, (iii) insurance, (iv) permits,
(v) payroll taxes and labor fringe benefits, and (vi) equipment by quantity and
rate.  All changes in any subcontract shall be broken down and similarly
submitted to the Owner for its review utilizing the same categories as set forth
above.

12.1.3  The cost or credit to the Owner resulting from a Change Order in the
Work shall be determined as provided in the Agreement.

12.1.4  The Owner, acting through its designee, or any other person having
written authorization from him to act on his behalf shall have the sole
authority to make any amendments, additions, changes or deletions, to act on
behalf of the Owner with regard to any and all consents called for under the
Contract Documents.  Said designee is hereby authorized by Owner to issue
written directives to Design/Builder to proceed with designated changes in the
Work prior to the issuance of a formal Change Order which shall be issued as
soon as practicable.  Verbal changes or Change Orders shall not be binding,
enforceable or effective.  Under no circumstances whatsoever, shall any Work be
performed on a time and material basis unless expressly authorized by Developer
in writing prior to commencement of such Work.  Any extras furnished by
Design/Builder except in accordance with the foregoing will also be done so at
Design/Builder's sole cost and expense and not reimbursable under the Agreement.

12.1.5  Owner and Design/Builder hereby acknowledge and agree that execution of
a Change Order constitutes a mutual accord and satisfaction as to the Work
covered thereby.  Upon execution of a Change Order, Design/Builder specifically
waives and releases any and all claims, rights or interest, including, but not
limited to those for impact, disruption, loss of efficiency, "ripple" or other
costs or expenses, including without limitation extraordinary or consequential
costs, arising directly or indirectly out of the Work described in the Change
Order.

12.2    CLAIMS FOR ADDITIONAL COST OR TIME
        ----------------------------------

12.2.1  If the Design/Builder wishes to make a claim for an increase in the
Contract Sum or change in the Contract Time, he shall give the Owner written
notice thereof within fifteen (15) days after receipt of a proposed Change
Order.  This notice shall be given by the Design/Builder before proceeding to
execute the Work, except in an emergency endangering life or property in which
case the Design/Builder shall proceed in accordance with Subparagraph 10.3.1.
No such claim shall be valid unless so made.  Any change in the Contract Sum or
Contract Time resulting from such claim must be authorized by Change Order.
Notwithstanding the foregoing, any change in the Contract Time shall be governed
solely by Section VI of the Agreement.

12.2.2  Complete justification and documented substantiation of a
Design/Builder's entitlement to additional time, to a change and additional
costs allegedly resulting from said change shall be submitted to the Owner no
later than thirty (30) days after Design/Builder files its initial notice of
claim.

                                      39
<PAGE>

12.2.3  In no event will any adjustment in the Contract Sum be permitted for any
increase in costs arising from periods of delay except as otherwise expressly
provided in the Contract Documents.

12.2.4  After receipt of a proposal, Owner shall act thereon within thirty (30)
days; provided, however, when the necessity to proceed with the change does not
allow time properly to review the proposal and in the event of a failure to
reach an agreement on said proposal, Owner may order Design/Builder to proceed
on the basis of a price to be determined at the earliest practicable date.

12.2.5  A failure to reach an agreement on price or time relative to a Change
Order will not relieve Design/Builder of its obligation to diligently continue
the prosecution of the Work and that Change Order (if so ordered by the
Developer) at all times in accordance with the Progress Schedule.

                                  ARTICLE 13

                       UNCOVERING AND CORRECTION OF WORK
                       ---------------------------------

13.1    UNCOVERING OF WORK
        ------------------

13.1.1  If any Work should be covered contrary to the request of the Owner, it
must, if required by the Owner, be uncovered for his observation and replaced,
at the Design/Builder's expense, and not reimbursable.

13.1.2  If any other portion of the Work has been covered which the Owner or
Developer has not specifically requested to observe prior to being covered, the
Owner or Developer may request to see such Work and it shall be uncovered by the
Design/Builder.  If such Work be found in accordance with the Contract
Documents, the cost of uncovering and replacement shall, by appropriate Change
Order, be charged to the Owner and the Contract Sum adjusted appropriately.  If
such Work is found not to be in accordance with the Contract Documents, the
Design/Builder shall pay such costs unless it be found that this condition was
caused by a separate contractor employed as provided in Article 6, and in that
event the Owner shall be responsible for the payment of such costs.

13.2    CORRECTION OF WORK
        ------------------

13.2.1  The Design/Builder shall promptly correct all Work rejected by or on
behalf of Owner as defective or as falling to conform to the Contract Documents
whether observed before or after Substantial Completion and whether or not
fabricated, installed or completed.  The Design/Builder shall bear all cost of
correcting such rejected Work, including the cost of any architect's additional
services thereby made necessary.

13.2.2  If, within two (2) years after the initial occupancy of the Project
after final completion of the Work, or within such longer period of time as may
be prescribed by law or by the terms of any applicable warranty required by the
Contract Documents, any of the Work is found to be

                                      40
<PAGE>

defective or not in accordance with the Contract Documents, the Design/Builder
shall correct it promptly after receipt of written notice from the Developer to
do so. The Owner shall give such notice promptly after discovery of the
condition.

13.2.3  All such defective or non-conforming Work under Subparagraphs 13.2.1 and
13.2.2 shall be removed from the Site if necessary, and the Work shall be
corrected to comply with the Contract Documents at Design/Builder's sole cost
and expense and without cost to the Owner or the Developer.

13.2.4  The Design/Builder shall bear the cost of making good all work of
separate contractors and property of Developer, Owner or any lessee or purchaser
destroyed or damaged by such removal or correction.

13.2.5  If the Design/Builder does not remove such defective or non-conforming
Work within twenty (20) days after notification of same, the Owner may remove it
and may store the materials or equipment at the expense of the Design/Builder.
If the Design/Builder does not pay the cost of such removal and storage within
ten (10) days thereafter, the Owner may upon the expiration of such period and
without further notice sell such Work at auction or at private sale and shall
account for the net proceeds thereof after deducting all the costs that should
have been borne by the Design/Builder including compensation for additional
architectural services.  If such proceeds of sale do not cover all costs which
the Design/Builder should have borne, the difference shall be charged to the
Design/Builder and an appropriate Change Order may be issued.  If the payments
then or thereafter due the Design/Builder are not sufficient to cover such
amount, the Design/Builder shall pay the difference to the Owner.

13.2.6  If the Design/Builder fails to correct such defective or nonconforming
Work, the Developer may also correct it in accordance with Paragraph 3.4.

13.2.7  Nothing contained in this Paragraph 13.2 shall be construed to establish
a period of limitation with respect to any other obligation which the
Design/Builder might have under the Contract Documents, including Paragraph 4.5
hereof.  Establishment of the time period of one (1) year as described in
Subparagraph 13.2.2 relates only to the specific obligation of the
Design/Builder 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 Design/Builder's liability with respect to the Design/Builder's obligations
other than specifically to correct the Work.

13.3    ACCEPTANCE OF DEFECTIVE OR NON-CONFORMING WORK
        ----------------------------------------------

13.3.1  If the Owner prefers to accept defective or non-conforming Work, he may
do so instead of requiring its removal and correction, in which case a Change
Order will be issued to reflect an appropriate reduction in the Contract Sum as
determined by Owner, or, if the amount is determined after Final Payment, or an
insufficient amount of the Contract Sum remains unpaid, it shall be paid
forthwith by the Design/Builder.

                     -------------------------------------

14.1    INTENT OF SPECIFICATION
        -----------------------

14.1.1  Certain materials and manufactured products have been or will be
specified by brand name because the Owner believes that the products sold under
those brand names meet the standard of quality and grade that he wishes to use
on this Work.  The Design/Builder shall use only the materials and methods
specified.

14.2    SUBSTITUTIONS
        -------------

14.2.1  The intention of the parties is, generally, not to exclude other
manufacturers of like products believed by the Design/Builder to be of the same
merit as and functionally equivalent to the item specified, but the burden of
proof of equivalency is upon the Design/Builder, and the Owner shall be the
final judge.  If the Design/Builder elects to attempt to prove such equality and
to substitute, he must request consent of Owner in writing within ninety (90)
days from Notice to Proceed, to substitute for the specified item, stating his
reasons for the substitution, the credit, if any, to the Contract Sum, and
provide supporting data.  Such supporting data shall include the basic
specifications of the specified item(s), the specifications, characteristics and
other information concerning the proposed substitution demonstrating its
equality to the specified item(s), and the effect of the substitution on the
Progress Schedule, if any.  In the event that a substitution is approved, the
Design/Builder shall assume all risks and costs for redesign and adjustment of
all Work affected by the substitution, checking of its effect on adjoining Work,
and any delays occasioned by its use.  All materials, methods or equipment shall
be as specified and/or shown unless a substitute or change is consented to in
writing by the Owner and therefore under no circumstances shall the
Design/Builder, Subcontractor, Sub-subcontractor, or supplier or materialman
base his bid or contract on a substitution unless consented to in writing in
advance by the Owner.

14.3    INSTALLATION
        ------------

14.3.1  Design/Builder shall apply, install, connect, erect, use, clean and
condition manufactured articles, materials, fixtures and equipment per
manufacturer's printed directions, unless specified to contrary.

        ---------------------------------------------------

15.1.1  Owner shall not assume nor shall there be imposed or implied any
responsibility whatsoever in respect to the sufficiency or accuracy of borings
made, or of the logs of the test borings, or of other investigations, or of the
interpretations made thereof, or other information

there is no warranty or guarantee, either expressed or implied, that the
conditions indicated by any such investigations, borings, logs or information
are representative of those existing throughout such area, or any part thereof,
or that unforeseen developments may not occur.

15.1.2  Design/Builder shall promptly notify Owner in writing of any physical,
subsurface or latent conditions that it discovers at the site that differ in any
material respect from those (i) ordinarily encountered and generally recognized
as inherit in Work of like character to the Project or (ii) indicated by the
Contract Documents.

15.1.3  Design/Builder shall make available to Owner upon Owner's request the
results of any site investigation, test borings, analysis, studies or other
tests conducted by or in the possession of Design/Builder or any of its agents.

Improvements (hereinafter referred to as the "Work").  It is understood and
agreed that the Work shall include all items expressed or implied by the
Contract Documents in order to deliver the completed Project free of gaps,
omissions or incompleteness thereof.  The term "Contract Documents" shall mean
this Agreement, all the items enumerated in Exhibit B, and all change orders or
                                            ---------
addenda issued with respect thereto.

          B.  From time to time after commencement of the performance of the
Work, Owner shall provide Design/Builder with information for its preparation of
the drawings and specifications for the Allowances, if any.  "Allowances" shall
refer to those items set forth in Exhibit D hereto.  The amounts listed for
                                  ---------
Allowances in such Exhibit D are included in the Contract Sum (as hereinafter
                   ---------
defined). Should the costs for performing Allowance Work differ from the amount
set forth in Exhibit D, such difference may be the subject of a Change Order and
             ---------
the Contract Sum may be adjusted pursuant to Section VIII hereinafter, subject
however to the following provisions.  Design/Builder, as part of its design
responsibilities, has and will participate in the development of the items of
Work included as Allowances and in the establishment of the Allowance values set
forth in Exhibit D hereto.  To the extent that the cost of an item included as
         ---------
an Allowance exceeds its Allowance value due to errors or omissions in
Design/Builder's calculations, take offs, quantities, or other information
prepared or provided by or on behalf of Design/Builder and utilized or relied
upon in establishing the Allowance, such shall not result in any adjustment in
the Contract Sum or be reimbursable as a Cost of Work.  Such excess costs may,
however, be paid from the Construction Contingency pursuant to the terms
thereof.

          C.  Design/Builder covenants that all the Work shall be done in a good
and workmanlike manner and that all Materials furnished and used in connection
therewith shall be new, free from faults and defects in conformance with the
Contract Documents and approved by

                                       7
<PAGE>

Owner. Design/Builder shall cause all Materials and other parts of the Work to
be readily available as required in connection with the construction of the
Improvements.

          D.  Design/Builder shall provide competent supervision of all phases
of the Work and shall cause the Work to be performed in accordance with the
Drawings and Specifications and all things indicated or implied therefrom.
Design/Builder shall provide the scheduling and periodic updating thereof in the
interest of completing the Improvements in the most expeditious and economical
manner (hereinafter called the "Progress Schedules").  The Progress Schedules
shall be prepared by Design/Builder prior to commencement of construction and
submitted to Owner for approval.  The Progress Schedules shall incorporate the
requirements of the design schedule prepared in connection with the Design
Contract, be consistent with the outline schedule attached hereto as Exhibit E
                                                                     ---------
and shall be related to the construction of all the Improvements to the extent
required by the Contract Documents.  These schedules shall indicate the dates
for the starting and completion of the various stages of construction and shall
be revised as required by the conditions of the Work, subject to Owner's
approval.  The parties acknowledge and agree that notwithstanding any
theoretical delays or theoretical extensions of time for completion as may be
shown on any schedules or printouts, the Scheduled Completion Date and Milestone
Completion Dates (hereinafter defined) shall be governed by this Agreement and
shall be extended only in accordance with the procedures set forth hereinafter.
If required by Owner, Design/Builder shall also prepare and furnish project cash
flow projections, manning charts for all key trades, and schedules for the
purchase and delivery of all equipment and material, together with periodic
updating thereof.

          E.  Design/Builder shall prepare all shop drawings and other detail
drawings not made a part of the Drawings and Specifications which are required
in the performance of Design/Builder's obligations hereunder, Design/Builder
will also provide and be responsible for all general conditions work such as
hoists, safety equipment, portable toilets, etc.

          Section VI.  Time for Performance
                       --------------------

          A.  Design/Builder shall commence performance of the Work upon
execution hereof and shall thereafter diligently continue the performance and
prosecution thereof to completion, and agrees to complete the performance of the
Work ("Completion") on or before the expiration of three hundred eighty (380)
calendar days from the date hereof (the "Scheduled Completion Date").  If
Design/Builder is delayed by any act or omission of Owner or by an employee,
agent, or representative of Owner (other than by reason of the proper exercise
of their respective rights, duties and obligations under the Contract
Documents), or by changes ordered in the Work, unforeseeable actions of public
utilities and governmental agencies, war, embargoes, causalities, acts of God or
the public enemy, national emergency, or unusually severe weather conditions
beyond that normally encountered and not reasonably anticipatable, then the
Scheduled Completion Date (and Milestone Completion Dates, if applicable) shall
be extended for a period equal to the length of such delay if within seven (7)
days after the commencement of any such delay Design/Builder delivers to Owner a
written notice of such delay stating the nature thereof and within ten (10) days
following the expiration of any such delay provides a written request for
extension of the Scheduled Completion Date (and Milestone Completion Dates, if
applicable) by reason of such delay, and such request is approved by Owner,
which approval shall not be

                                       8
<PAGE>

unreasonably withheld. Failure to deliver any such notice or request within the
required period shall constitute an irrevocable waiver of any extension of the
Scheduled Completion Date and Milestone Completion Dates by reason of the cause
in respect of which such notice and request were required. In the case of the
continuing cause of delay of a particular nature, Design/Builder need make only
one request with respect thereto. Shortages of labor, shortages or
unavailability of standard building materials, a normal number of adverse
weather days, and the customary time periods to obtain approvals from and
inspections by municipal authorities shall in no event entitle Design/Builder to
an extension of time. No delay of the Scheduled Completion Date (or right on the
part of Design/Builder to secure any such delay) shall prejudice any right Owner
may have under this Agreement or otherwise to terminate this Agreement.

          Design/Builder has included in its schedule thirty (30) work days lost
due to weather conditions in its schedule.  Design/Builder will record on a
daily basis whether its job progress has been materially affected by adverse
weather conditions.  Work day, as that term is used herein, shall mean and refer
to any of Design/Builder's normal eight (8) hour days, Monday through Sunday of
any given week, exclusive of customarily recognized and agreed national
holidays.  No application for extension of time will be made unless or until
Design/Builder has lost in excess of the above number of days on which he had
planned and scheduled work on items that materially affect the schedule.
Design/Builder shall not be entitled to any extension of time, change order,
adjustment of the Contract Sum or other compensatory or non-compensatory relief
for events of delay or force majeure other than those specifically set forth
above in this Section VI(A), and then only pursuant to the notice procedures
hereinabove and subject to the limitations of the third paragraph of this
Section VI(A). Design/Builder acknowledges and agrees that its assumption of the
risks and responsibilities for delay is a material inducement to Owner's award
of the Agreement to Design/Builder and material consideration in Owner's
agreement to the Contract Sum, Scheduled Completion Date, Milestone Completion
Dates and other provisions of this Agreement and shall not be modified or
subject to interpretation other than as expressly set forth herein for any
reason, including without limitation, custom, practice, industry standards or
prior conduct or agreements.

          Extension of time shall be Design/Builder's sole and exclusive remedy
for any event of delay hereunder, unless the same shall have been caused by acts
constituting intentional interference by Owner with Design/Builder's performance
of the Work and then only to the extent that such acts continue after
Design/Builder's written notice to Owner of such interference.  Owner's exercise
of any of its rights under Section VIII regardless of the extent or number of
such changes, or Owner's exercise of any of its remedies of suspension of the
Work or requirement of correction or re-execution of any defective Work shall
not under any circumstances be construed as interference with Design/Builder's
performance of the Work.

          B.  In the event of the occurrence of a delay for which Design/Builder
is not entitled to an extension of time by the terms of this Agreement, Owner
may direct that the Work be accelerated by means of overtime, additional crews
or additional shifts or resequencing of the Work.  All such acceleration shall
be at no cost to Owner.  Owner may similarly direct acceleration in the event of
the occurrence of a delay for which Design/Builder is entitled to an extension
of time by the terms of this Agreement, and/or notwithstanding that the Work is
progressing without delay in accordance with the Progress Schedules.
Design/Builder agrees to

                                       9
<PAGE>

perform same on the basis of reimbursement of direct cost (i.e., premium portion
of overtime pay, additional crew, shift or equipment cost and such other items
of cost requested in advance by Design/Builder and approved by Owner which
approval will not be unreasonably withheld) plus a fee not to exceed five
percent (5%) of such cost but expressly waives any other compensation therefor
unless otherwise agreed in writing in advance of performing the accelerated
work. In the event of any such acceleration, Design/Builder shall provide a plan
including his recommendations for the most effective and economical
acceleration. Acceleration which is compensible under this Section VI (B) shall
be subject to the Change Order procedure set forth in Section VIII herein.

     C.   As used in this Agreement, Completion shall mean Substantial
Completion, which includes all work (exclusive of minor items of unfinished work
which do not preclude beneficial use of the premises) to complete the base
building, tenant finish and other work set forth in the Contract Documents and
that each of the following shall have occurred: when (i) the Improvements have
been completed except for punch list items (i.e., minor or insubstantial details
of the construction or mechanical adjustments which do not materially interfere
with the tenant's occupancy and use of the Project for the conduct of its
business), (ii) a certificate of occupancy or its equivalent shall have been
obtained for the Project permitting entry and legal use thereof for the
installation of trade fixtures, decorations, equipment and other items to be
constructed or installed by tenants, and for tenant's business activities to be
conducted therein, and all governmental approvals required for completion have
been obtained, and (iii) Architect shall have issued a Certificate of
Substantial Completion certifying thereon the date of Substantial Completion.
Without limiting the foregoing, Substantial Completion shall not have occurred
unless and until the following have been completed, and, where applicable, are
operational, except for punch list items: (a) the exterior curtain wall, window
glass and other applicable exterior elements of the Project are completed as
necessary to be water tight, (b) all utility lines servicing the Project are
installed and capable of being used to provide the applicable utilities to the
Project, (c) the restrooms, (d) all elevators, (e) the tenant parking spaces,
(f) the public entrances and all lobbies, (g) all freight elevators, and (h) the
loading docks. Notwithstanding the delivery of a Certificate of Substantial
Completion by Architect, Substantial Completion shall not be deemed to have
occurred until Design/Builder has provided Owner written notice at least thirty-
five (35) days prior to the anticipated date of Substantial Completion.
Design/Builder shall be afforded forty-five (45) calendar days from the
Scheduled Completion Date within which to complete the minor items of unfinished
work (the punch list work) referred to above.

     D.   In addition to Completion as defined and specified herein and
Design/Builder's obligation to meet the Scheduled Completion Date,
Design/Builder agrees to and shall complete construction of the following items
included within the Work on or before the time set forth herein.

</TABLE>

     Commissioning Phase: All mechanical, electrical and HVAC systems, energy
conservation equipment, controls, lighting systems, security systems back-up
generation and UPS, fire management systems, elevators are complete so that the
aforementioned systems can be tested for verification of compliance with the
approved Drawings and Specifications.

     Computer/Telecommunication Room Completion: All construction, including but
not limited to, electrical, HVAC, raised flooring, UPS, finishes, and secured
doors, related to commencing and completing the installation and testing of all
computer equipment in the main computer/telecom room of the Project (as shown on
the approved Drawings and Specifications Building Plans) shall be complete.

     Initial FF&E Phase: All construction necessary and related to commencing
the initial phase of furniture installation shall be complete, including all
areas in which furniture is to be installed and shall include all related
construction, including but not limited to, flooring, painting, above ceiling
work and any adjacent construction that may otherwise impede the progress of, or
damage, the installed furniture systems. On or about ninety (90) days after the
commencement of construction, Owner shall notify Design/Builder as to what
portion of the premises shall be included in this Initial FF&E Phase. Owner
shall also provide Design/Builder with a written schedule of its complete FF&E
phasing plan for the entire Project once it has been determined by Owner.

     The above items shall be referred to as the "Milestone Completion Dates."
Design/Builder shall notify Owner in writing upon the completion of an item of
Work that is subject to a Milestone Completion Date, and in such notice shall
set forth the date completion occurred (which shall not be more than three (3)
days prior to said notice).

     E.   Design/Builder acknowledges that the Scheduled Completion Date and the
Milestone Completion Dates are essential to Owner's business operations,
leasing, marketing, financing and development plans and therefore time is of the
essence in meeting said dates. Design/Builder recognizes and agrees that it
shall be liable to Owner for damages, loss, cost or expense which Owner may
suffer by reason of Design/Builder's delay in meeting such dates. Design/Builder
further recognizes that its schedule and the Outline Schedule set forth as
Exhibit E hereto may be subject to reasonable adjustment or modification based
---------
on the designations set forth in Owner's Initial FF&E Phase and in the complete
FF&E phasing plan, and Design/Builder agrees that such shall not result in any
extension to any Milestone Completion

                                      11
<PAGE>

Date or to the Scheduled Completion date, nor shall it constitute interference
by Owner or be otherwise compensible to Design/Builder.

          Section VII.  Permits and Licenses
                        --------------------

          Design/Builder shall obtain all necessary licenses, building and other
permits, and similar authorizations from governmental authorities required to
perform its obligations hereunder, and shall give all notices required by, and
otherwise comply with, all applicable laws, ordinances, rules, regulations and
restrictions.  Design/Builder shall notify Owner of all conflicts between the
Drawings and Specifications and any laws, ordinances, rules, regulations and
restrictions.  If Design/Builder performs any of the Work knowing, or when with
the exercise of due care it should have known, the same to be contrary to any
such laws, ordinances, rules, regulations or restrictions and fails to give
Owner written notice thereof prior to performance thereof, Design/Builder shall
bear all costs arising therefrom, which costs shall not be considered a part of
the Contract Sum.

          Section VIII.  Changes
                         -------

          A.  Owner, or if authorized by Owner, its Developer, may authorize
changes in the Work, issue additional instructions, require additional Work or
direct the omission of Work previously ordered; provided, however,
Design/Builder shall not under any circumstances proceed with any change
involving any increase or decrease in cost without prior written authorization
from Owner in accordance with the following procedure.

          Owner, or if authorized by Owner, its Developer, shall order changes
in the Work by giving Design/Builder a written change order request ("Change
Order Request"), setting forth in detail the nature of the requested change.
Design/Builder shall then furnish Owner a statement setting forth in detail,
with a suitable breakdown by trades and work classifications, Design/Builder's
estimate of the changes, if any, in the Estimated Design/Build Cost attributable
to the changes set forth in such Change Order Request, a proposed adjustment, if
any, to the Scheduled and/or Milestone Completion Dates resulting from such
Change Order Request and any proposed adjustments of time and costs related to
unchanged Work resulting from such Change Order Request.  If Owner gives written
approval of such estimate, such Change Order Request and estimate shall
constitute a Change Order, and the Contract Sum and Scheduled Completion and/or
Interim Dates shall be adjusted as set forth therein.  Change Orders shall not
cause any modification to Design/Builder's Fee except as follows:  if upon
completion of the Work the net of all additive and deductive Change Orders has
resulted in an increase in the Guaranteed Maximum Cost, then Design/Builder
shall be entitled to a fee in the amount of five percent (5%) of the cost of
such change Order Work ("Change Order Work"); if the net of all additive and
deductive Change Orders has resulted in a decrease in the Guaranteed Maximum
Cost, then Design/Builder's Fee shall be reduced by three percent (3%) of the
cost of such Change Order Work.  It is further understood and agreed that
Subcontractors' and Sub-subcontractors' mark-up on Change Order Work shall not
exceed fifteen percent (15%), and such limitation shall be included in each
subcontract, with any amounts therefor in excess hereof being for the account of
Design/Builder and not Owner and not reimbursable as a Cost of the Work.
Design/Builder's Fee and adjustments set forth above, and the Subcontractor's
mark-ups,

                                      12
<PAGE>

includes the fee, overhead and profit. Changes in the Work and Change Orders
shall include charges for design services only if and to the extent such are for
Additional Services as provided in the Design Contract. Additional Services, if
any, shall be charged without Design/Builder's Fee or Subcontractor's mark-ups
set forth above. Agreement on any Change Order shall constitute a final
settlement on all items covered therein. If the parties cannot agree on the cost
of Change Order Work, Design/Builder will proceed with the Work and the cost
will be determined in accordance with Section IX(B) hereof.

          B.  It is understood and agreed that refinement and detailing will be
accomplished from time to time with respect to the Drawings and Specifications
to be set forth in the modified Exhibit B.  No adjustment in the Estimated
                                ---------
Design/Builder's Cost, Cost of the Work, Guaranteed Maximum Cost or in the
Scheduled and/or Milestone Completion Dates shall be made unless such refinement
or detailing results in changes in the scope, quality, function and/or intent of
the Drawings and Specifications not reasonably inferable or anticipatable by a
design-build construction manager/general contractor of Design/Builder's
experience and expertise.

          C.  Change Order requests shall not be considered by Owner unless
prior written notice of the proposed Change Order is submitted to the Developer,
together with documentation detailing the proposed increase or decrease in the
Contract Sum caused by the proposed Change Order before commencement of the Work
contemplated therein.  No act, conduct or practice of Owner, Developer or any
other person or party shall constitute or result in a waiver of this
requirement, it being expressly understood and agreed that such requirement may
only be waived in writing.  Design/Builder shall price Change Orders which
involve material scope changes to the Project on the basis of competitive
pricing for such Work.

          Section IX.  Payments
                       --------

          A.  In full consideration of the full and complete performance of the
Work and all other obligations of Design/Builder hereunder, Owner shall pay to
Design/Builder a sum of money equal to the "Contract Sum" which is defined to be
the total of (i) the Cost of the Work, as hereinafter defined, (ii) the
Architect's Fee and Reimbursables, (iii) Design/Builder's Fee listed below,
subject to adjustment as provided in the Contract Documents, and (iv) the
Construction Contingency, which Contract Sum shall not exceed Twenty Five
Million, Three Hundred Twenty Six Thousand, Seventeen and 00/100 Dollars
($25,326,017.00) (hereinafter referred to as the "Guaranteed Maximum Cost")
subject to adjustments as provided in the Contract Documents, which Guaranteed
Maximum Cost consists of the following:

     Estimated Design/Builder's Cost                $22,583,252.00
     (including Allowances)

     Architect's Fees and Reimbursables               1,520,657.00

     Design/Builder's Fee                               722,108.00

     Construction Contingency                           500,000.00

     Guaranteed Maximum Cost                        $25,326.017.00

                                      13
<PAGE>

          The Architect's Fee and Reimbursables includes the unpaid balance of
the Design Contract. Such amount includes all fees, reimbursable expenses and
other amounts payable for design, architectural or engineering services under
the Design Contract or otherwise in connection with Design/Builder's design
obligation hereunder, and Design/Builder assumes responsibility for all amounts
now or hereafter owing to Architect.

          The "Design/Builder's Fee" as listed above is defined to be the amount
equal to the fixed sum of Seven Hundred Twenty-Two Thousand One Hundred Eight
and 00/100 Dollars ($722,108.00) (subject to adjustment for the cost of Change
Order Work as provided in Section VIII hereof) subject to the adjusted
Guaranteed Maximum Cost. In the event that the Cost of the Work is less than the
adjusted Estimated Design/Builder's Cost, then Design/Builder's Fee shall remain
Seven Hundred Twenty-Two Thousand One Hundred Eight and 00/100 Dollars
($722,108.00) subject to adjustment pursuant to Section VIII hereof. In the
event that the Cost of the Work is greater than the adjusted Estimated
Design/Builder's Cost and less than the adjusted Guaranteed Maximum Cost, then
Design/Builder's Fee shall be equal to the Cost of the Work subtracted from the
adjusted Guaranteed Maximum Cost (minus the Architect's Fee and Reimbursables
and minus the Construction Contingency), subject to further adjustment pursuant
to the provisions of Section VIII hereof. In the event that the Cost of the Work
shall exceed the Guaranteed Maximum Cost, adjusted as provided herein,
Design/Builder shall pay such excess from its own funds and Owner shall not be
required to pay any part of such excess, and Design/Builder shall have no claim
against Owner on account thereof.

          The "Construction Contingency" set forth in this Section IX is
included within the Guaranteed Maximum Cost and is the maximum sum available to
cover the costs (including impact costs) resulting from unforeseen conditions
and events not evidenced at the time of execution of this Agreement, such as (1)
refinement of details of design within the scope and standards of quality and
quantities on which the estimate was based, (2) abnormal field conditions, (3)
impact costs on materials and labor due to Change Orders, (4) time extensions,
(5) delays due to unusually severe weather conditions not reasonably
anticipatable, or (6) other causes of lost time which result in added costs or
claims which are not otherwise recoverable hereof.

          The use of the Construction Contingency shall be mutually agreed upon
between Owner and Design/Builder; provided, however, that Design/Builder shall,
as a part of the monthly progress report, provide Owner with a statement on the
use of the Construction Contingency setting out charges made, if any, against
the Construction Contingency, and further noting the balance remaining in the
Construction Contingency. No sums may be charged to the Construction Contingency
except upon the mutual agreement of Owner and Design/Builder and then only to
the extent that the same have been paid or are to be paid by Design/Builder. All
charges to the Construction Contingency will be pursuant to appropriate Change
Order decreasing the amount of the Construction Contingency and increasing the
Estimated Design/Builder's cost with no adjustment of the Guaranteed Maximum
Cost. Any Construction Contingency remaining at the time of Final Payment shall
innure to the benefit of Owner.

          In the event that the Cost of the Work shall be less than the
Estimated Design/Builder's Cost, adjusted as provided herein, the difference
between such Cost of the Work and such

                                      14
<PAGE>

Estimated Design/Builder's Cost shall constitute "Savings" (hereinafter so
called). Twenty-five percent (25%) of such Savings shall be paid to
Design/Builder as an additional fee ("Additional Fee"); the balance of all such
Savings shall accrue to Owner. In no event shall sums included under the
Construction Contingency, as Allowances or resulting from deductive Change
Orders or other reductions in the scope of the Project be used in the
determination of Savings; provided, however, that the foregoing shall not result
in an exclusion from Savings of reductions in costs achieved through the use of
substitutions or alternatives approved by Owner and first proposed by
Design/Builder after the execution hereof. Approval of any such substitutions or
alternatives shall be at Owner's sole discretion.

          It is agreed that Design/Builder's Fee and any possible earnings under
the Additional Fee paragraph above are Design/Builder's full and complete fee
compensation for performing both the design and construction of the Work as
listed herein.

          B.  The term "Cost of the Work" shall mean a sum of money equal to the
total of all of Design/Builder's Costs, as hereinafter defined.  The term
"Estimated Design/Builder's Cost" shall mean that sum of money set forth in
Section IX(A) opposite the term "Estimated Design/Builder's Cost," subject to
adjustment as provided in the Contract Documents, which sum is Design/Builder's
estimate of all Design/Builder's Costs that are to be incurred and paid by
Design/Builder in the performance of the Work.  The term "Design/Builder's
Costs" shall mean those costs necessarily incurred and paid by Design/Builder in
connection with the proper performance of all the Work.  Such Design/Builder's
Costs shall be at rates not higher than the standard paid in the locality of the
Work, except with prior written consent of Owner, and shall include and be
limited to the following items:

              (1)  Wages paid for labor, including without limitation that of
     design personnel in the direct employ of Design/Builder in the performance
     of the design or construction of the Work under applicable collective
     bargaining agreements, or under a salary or wage schedule agreed upon by
     Owner and Design/Builder, and including welfare or other fringe benefits,
     if any, as may be payable with respect thereto, and usual vacation pay and
     incentive bonuses made by Design/Builder to its key employees engaged at
     the construction site.

              (2)  Salaries and fringe benefits of Design/Builder's design
     professional, supervisory or administrative personnel when assigned to and
     working on the Project and/or stationed at the field office, in whatever
     capacity employed when necessary for the performance of the Work; such
     personnel being subject to the approval in advance by the Developer.
     Personnel engaged, at shops or on the road, in expediting the inspection,
     production or transportation of material (including equipment) for the
     Work. The number of employees in these classifications, and the rates of
     pay, shall be subject to the prior approval of Owner.

              (3)  Cost of contributions, assessments or taxes for such items as
     Unemployment Compensation and Social Security, insofar as such cost is
     based on the wages, salaries, or other remuneration paid to employees of
     Design/Builder referred to in Section IX(B) (1) and (2) hereof.

                                      15
<PAGE>

          (4)  Reasonable relocation, transportation, traveling and lodging
     expenses (as approved by Owner) of representatives of Design/Builder
     incurred in the discharge of duties related to the Work.

          (5)  The cost (including transportation, storage, operating and repair
     costs except of a capital nature) of all materials, equipment, temporary
     structures, small tools not owned by workmen and supplies purchased or
     rented for use in the performance of the Work.  Such costs shall include a
     fair rental not to exceed eighty percent (80%) (unless otherwise approved
     by Owner) of the published rates based on "Compilation of Nationally
     Averaged Rental Rates", most recent edition, of the Associated Equipment

     at the time first utilized in connection with the Work.  Owner reserves the
     right to dispose of all such materials, equipment, temporary structures,
     tools and supplies which shall have been purchased, when no longer required

     Design/Builder shall exercise its best efforts to enforce such requirements
     or to effect an appropriate back charge to those subcontractors who fail to
     meet their requirements in this regard.) Provided, however, Design/Builder
     shall not be required to remove debris created by Owner's separate

     Owner, except to the extent that any such cost is reimbursable by insurance
     or otherwise, or is the responsibility of Design/Builder, or is due to the
     failure of Design/Builder to comply with the requirements of the Contract
     Documents with respect to insurance or to the failure of any officer of
     Design/Builder or of any of its representatives having supervision or
     direction of the Work to exercise good faith or at least the standard of

          (15)  Federal, state, municipal, sales, use and other taxes, all with
     respect to Services performed or materials or equipment furnished for the

     compensated by insurance or otherwise, sustained by Design/Builder in
     connection with the Work provided they have resulted from causes other than
     the actual fault, neglect or responsibility of Design/Builder.  Such losses
     shall include settlements made with the written consent and approval of
     Owner.  No such losses and expenses shall be included in the Cost of the
     Work for the purpose of determining Design/Builder's Fee.  If, however,
     such loss requires reconstruction and Design/Builder is placed in charge
     thereof, he shall be paid for its services a fee proportionate to that
     stated in Section IX(A).

     D.   On or before the twenty-fifth (25th) day of each month during the
performance of the Work, Design/Builder shall submit to Owner for its approval a
request for payment ("Request for Payment") in form and substance satisfactory
to Owner (simultaneously therewith sending copies to such other parties as Owner
may direct).  Each Request for Payment shall be for a sum equal to (i) all of
Design/Builder's Cost incurred during the preceding month and (ii) ninety
percent (90%) of the pro rata portion of Design/Builder's Fee attributable to
Design/Builder's Cost set forth in such Request for Payment; provided, however,
that prior to the date of the Final Request for Payment, as hereinafter defined,
the aggregate of Design/Builder's Fee payments shall not exceed ninety percent
(90%) of Design/Builder's Fee amount as stated in Section IX(A) herein.
Design/Builder's Costs shall be segregated and detailed in a manner satisfactory
to Owner.  Requests for Payment shall include the value of materials or
equipment not incorporated in the Work but delivered and suitably stored at the
site or at some location agreed upon.  Title to all such equipment and materials
shall pass to Owner upon payment therefor or incorporation in the Work,
whichever shall first occur, and Design/Builder shall prepare and execute all
documents necessary to effect such transfer of title.

     In each Request for Payment, Design/Builder shall certify that such Request
for Payment represents the amount due to Design/Builder under the terms of
Section IX(B) and shall also certify as follows:

     "There are no known mechanics' or materialmen's liens outstanding at the
date of this requisition, all due and payable bills with respect to the Work
have been paid to date or are included in the amount requested in the current
application, and except for such bills not paid but so included, there is no
known basis for the filing of any mechanics' or materialmen's liens on the Work,
and releases from all subcontractors and materialmen have been obtained in such
form as to constitute an effective release of lien under the applicable laws of
the State of Texas."

     Design/Builder shall furnish with each Request for Payment certification by
the Architect that all amounts so requested by Design/Builder are properly due
and owing and that the Work corresponding to the amounts requested in each
Request for Payment has been properly performed and completed in accordance with
this Agreement, the Drawings and Specifications, the Preliminary Building Plans
and the other Contract Documents. Architect shall make such certifications as if
Architect was engaged separately by Owner to provide architectural and contract
administration services.

     Design/Builder shall furnish with each Request for Payment a waiver and
release of lien for itself and, beginning with the second Request for Payment,
for each of its subcontractors and suppliers having a contract or purchase order
of $10,000.00 or more, together with any other

                                      19
<PAGE>

such forms required by Owner or Owner's title insurer or lender in order to
assure an effective release of mechanics' or materialmen's liens in compliance
with the applicable laws of the situs of the Project.

     Design/Builder shall submit with each Request for Payment a monthly
progress report which shall set forth in detail the status of the Project as of
the date of such Request for Payment. The format of the progress report shall be
determined by Owner prior to submission of the initial Request for Payment,
however, the progress reports shall at a minimum describe those aspects of the
Work which have been commenced and the status thereof, enumerate the trades and
subcontractors then involved in the Work and the amount of personnel employed on
the Project by them, set forth the schedule for major portions of the Work for
the coming month, and include Design/Builder's appraisal of the progress and
cost of the Work together with recommendations as to any action which is
required by Owner. Each monthly progress report shall be accompanied by an
update of the CPM schedule (diagram only), the form of which shall be mutually
agreed to by Owner and Design/Builder at the time the format for the progress
report is determined. Additionally, Design/Builder shall provide Owner with
monthly progress photos of the Work. Design/Builder shall also furnish with each
Request for Payment complete cost detail and supporting documentation
substantiating the amounts set forth in the Request for Payment, including
copies of subcontractors' pay requests, invoices, labor sheets and other
information substantiating Design/Builder's right to payment, summarized and
verified by Design/Builder's accounting department. Owner may make such
adjustments to Design/Builder's previous, current or subsequent Requests for
Payment as warranted by Owner's review of the supporting documentation submitted
by Design/Builder.

     Design/Builder shall not submit any Request for Payment which is
incomplete, inaccurate or lacks the detail, specificity or supporting
documentation required by this Section IX(B). Any Request for Payment that is
deficient in any such manner shall not constitute a valid Request for Payment,
and Design/Builder shall be required to resubmit said Request for Payment in
proper form prior to Owner incurring any obligation to make payment on account
thereof. Design/Builder specifically agrees that it shall not include in any
Request for Payment sums attributable to Work which Owner or Design/Builder have
rejected or which otherwise constitute or relate to applications for payments,
billings or invoices of subcontractors or suppliers which Design/Builder
disputes or for any other reason does not intend to pay.

     Owner shall review each such Request for Payment and make such exceptions
as Owner reasonably deems necessary or appropriate under the current
circumstances. In no event shall Owner be required to make payment for items
disallowed by its lender(s).

     On or about thirty (30) days following receipt of a Request for Payment
(unless such date falls on a weekend or holiday, then on the next business day)
and provided Design/Builder has submitted its Request for Payment and supporting
documentation in the manner and detail required by this Agreement, Owner shall
make payment to Design/Builder in the amount approved subject to Section IX(F)
hereof. The payment of any Request for Payment by Owner, including the final
Request for Payment, does not constitute approval or acceptance of any item of
cost in such Request for Payment.

                                      20
<PAGE>

     Design/Builder agrees that ten percent (10%) of the amount due under each
subcontract shall be retained by Owner until final payment ("Final Payment"),
except that upon mutual agreement by Owner and Design/Builder, and with Owner's
lender's prior approval, payment in full may be made to those subcontractors
whose work is fully completed during the early stages of the Project or reduced
with respect to other contractors at such times as the parties may mutually
agree. Agreement to any such reduction shall not constitute a waiver of or
prejudice Owner's right to subsequently reinstitute full retainage should
circumstances justify such action in Owner's sole judgment.

     Retainage under subcontracts shall be included in Design/Builder's Request
for Payment for the purpose of indicating the value of the Work performed,
however, Design/Builder shall not request payment thereof from Owner until such
retainage is actually payable hereunder.

     Thirty (30) days after final completion of the Work and acceptance thereof
by Owner or as soon thereafter as possible, Design/Builder shall submit a final
request for payment ("Final Request for Payment") setting forth all amounts due
and remaining unpaid to Design/Builder. The Additional Fee, if any, shall be due
and payable only after Design/Builder's Costs are finally established and agreed
to by Design/Builder and Owner. The Final Request for Payment shall not be made
until Design/Builder delivers to Owner a complete release of all liens arising
out of this Agreement and an affidavit that so far as Design/Builder has
knowledge or information the release includes all Materials and Services for
which a lien could be filed. Design/Builder may, if any subcontractor or
supplier refuses to furnish a release in full, furnish a bond satisfactory to
Owner, Owner's title insurer and lender to indemnify Owner and such other
parties against any lien. Upon approval by Owner, Owner shall pay the amount due
under such Final Request for Payment. Anything to the contrary notwithstanding,
Final Payment shall not be made prior to thirty (30) days following final
completion of the Work.

     E.   In no event shall any interest be due and payable by Owner to
Design/Builder, any subcontractor or any other party on any of the sums retained
by Owner pursuant to the Contract Documents.

     F.   Any provision to the contrary notwithstanding, Owner shall not be
obligated to make payment hereunder if one or more of the following conditions
exists:

          (1) Design/Builder is in default of any of its obligations hereunder
     or otherwise is in default under any Contract Documents;

          (2) Any part of such payment is attributable to Work that is defective
     or not performed in accordance with the Drawings and Specifications;
     provided, however, payment shall be made for Work performed in accordance
     with the Drawings and Specifications and not defective;

          (3) Design/Builder has failed to make payments promptly to
     subcontractors or for material or labor used in the Work for which Owner
     has made payment to Design/Builder;

                                      21
<PAGE>

          (4) Owner in good faith determines that the portion of the Guaranteed
     Maximum Cost then remaining unpaid will not be sufficient to complete the
     Work in accordance with the Drawings and Specifications and the Preliminary
     Building Plans, whereupon no additional payments will be due unless and
     until Design/Builder, at its sole cost, performs a sufficient portion of
     the Work so that the portion of the Guaranteed Maximum Cost remaining
     unpaid is determined by Owner to be sufficient to complete the Work, or

          (5) Owner in good faith determines that Design/Builder has not or will
     not with prompt acceleration meet the Scheduled Completion Date.

     No partial payment or release of retainage shall constitute final
acceptance or approval of the Work to which such partial payment relates or
relieves Design/Builder of any obligations hereunder.

     G.  Except for Design/Builder's Fee and the Additional Fee, if any,
Design/Builder shall use the sums advanced to it pursuant to this Section IX
solely for the purpose of performance of the Work and the design of the Project
and the construction of the Improvements in accordance with the Drawings and
Specifications. No provision hereof shall be construed to require Owner to see
to the proper disposition or application of the monies paid Design/Builder.

     H.  On or before the date of submittal of the initial Request for Payment,
Design/Builder shall furnish to Owner and Owner's lender an affidavit,
subordination and lien waiver agreement executed by Design/Builder. The
agreements shall be in form and substance satisfactory to Owner and Owner's
lender. Each party executing such agreement shall agree to subordinate its liens
for Work to be performed or Materials to be furnished to the liens and security
interests securing payment of any loan made by Owner's lender, and shall furnish
a release of all liens for Work performed and Materials furnished to the date of
such agreement. Each such party shall certify that all amounts owing to such
party through the date of such agreement have been paid in full, or if not paid
in full, shall set forth all such unpaid amounts.

     I.  Design/Builder shall within ten (10) days following receipt of payment
from Owner pay all bills for labor and material performed and furnished by
others in connection with the design and/or construction of the Improvements and
the performance of the Work, and upon request by Owner shall provide Owner with
evidence of such payment. Design/Builder's failure to make payments within such
time shall constitute a material breach of this Agreement.

     J.  Upon completion of the Work or the appropriate parts thereof, and
subject to Owner's prior approval thereof and right to take title thereto
pursuant to Section IX(B)(5) hereof, Design/Builder shall sell to a third party
or transfer to itself at the then fair market value thereof, all hoists,
scaffolding, forms, hand tools and other items purchased for use in the Work
with funds furnished as a part of Design/Builder's Costs. The amounts received
from such sale (or the fair market value thereof in the case of transfer to
Design/Builder) shall be credited against the amounts due from Owner hereunder.

                                      22
<PAGE>

          Section X.  Discounts Rebates and Refunds
                      -----------------------------

          Design/Builder shall take affirmative steps to ensure that is takes
full advantage of any and all available discounts, rebates, refunds and returns.
All cash discounts shall accrue to the Cost of the Work, and Design/Builder
shall notify Owner of the availability of such cash discounts in order that
Owner may make available funds therefor.  If Design/Builder shall fail to so
notify Owner, such cash discount shall accrue to the Cost of the Work.  All
trade discounts, rebates and refunds, and all returns from sale of surplus
materials and equipment shall accrue to the Cost of the Work and Design/Builder
shall endeavor to make provisions for the securing thereof.  Any discounts
accruing to the Cost of the Work pursuant to this paragraph shall not result in
adjustment of the Guaranteed Maximum Cost.

          Section XI.  Compensation Retained by Owner
                       ------------------------------

          Design/Builder acknowledges that the Scheduled Completion Date and
Milestone Completion Dates are essential to Owner's leasing, marketing,
financing and development plans and therefore TIME IS OF THE ESSENCE in meeting
said dates. Design/Builder agrees that from the Contract Sum to be paid to
Design/Builder in accordance with the Contract Documents, Owner may retain as
"Delay Damages" twelve thousand five hundred and 00/100 Dollars ($12,500.00) per
day for each of the first forty (40) calendar days (including Saturdays, Sundays
and holidays) the Work remains uncompleted, which elapse between the time the
Work (or the relevant portion thereof) should have achieved Milestone or
Substantial Completion under the terms of the Contract Documents and the date
the Work (or the relevant portion thereof) actually achieves Milestone or
Substantial Completion, as applicable.  Design/Builder further agrees that the
Delay Damages shall be at the rate of twenty-five thousand and 00/100 Dollars
($25,000.00) per day for each such day after the first forty (40) days that such
Work remains uncompleted.  The foregoing amounts of Delay Damages shall
compensate Owner solely for the Project's unavailability and Owner's resulting
inability to use the Project for its intended purposes, and do not include (i)
any damages, additional costs or extended costs incurred by Owner for extended
administration of this Agreement or by Owner's agents, consultants, or
independent contractors for extended administration, (ii)  any increase in
financing costs resulting from the delay, (iii) actual costs incurred by Owner's
tenant and assessed or charged to Owner (including but not limited to costs of
storing tenant's furniture, fixtures, equipment or materials and cost of
overtime to complete the installation thereof), or (iv) any additional services
relating to, or arising as a result of the delay.  Owner shall be entitled to
claim against Design/Builder for its actual damages, including those as set
forth herein, which costs shall be computed separately.  Together with the per
diem Delay Damages, an amount equal to Owner's actual damages shall be either
deducted from the Contract Sum and/or billed to Design/Builder.  The parties
acknowledge and agree that the cost and expense to Owner for its inability to
use the Project are difficult if not impossible to determine, and the foregoing
per diem amounts represent amounts which Design/Builder acknowledges and agrees
Owner shall be entitled to recover and withhold without further demonstrating or
evidencing the nature, source, cause or value of Owner's damages.  The sums set
forth above are not to be construed in any way as a penalty, nor shall they
constitute liquidated damages or limit Owner from the recovery of the other
actual damages provided for herein and excluded from the damages for delayed
availability and use of the Project by Owner.

                                      23

          Section XII.  Subcontracts and Purchase Orders
                        --------------------------------

          A.  Design/Builder shall invite bids from, and enter into contracts
and material orders with only subcontractors and suppliers who have first been
approved by Owner.  After receiving such bids, Design/Builder shall analyze them
and make recommendations for awards, accompanying its recommendation with all
pertinent data required for decision upon the award, and certifying that, to the
best of its knowledge, the bid of the recommended subcontractor or supplier is
bona fide, fair and reasonable.  All subcontracts shall, so far as practicable,
contain unit prices and any other feasible formula for use in the determination
of the cost of changes in the Work.  Design/Builder agrees to hold all
subcontractors, including all persons directly or indirectly employed by them,
responsible for any damages due to breach of contract or any negligent act and
to diligently endeavor to effect recoveries of such damages.

          B.  Design/Builder shall contract solely in its own name and behalf
and not in the name or behalf of Owner, with the specified subcontractor or
supplier.  Design/Builder's subcontract and purchase order forms shall be
subject to approval of Owner and shall provide that subcontractor shall perform
its portion of the Work in accordance with all applicable provisions of this
Agreement and the other Contract Documents.  Design/Builder shall submit its
subcontract and purchase order forms to Owner for approval prior to use in
connection with the project, and shall promptly deliver to Owner a copy of all
executed subcontracts and purchase orders entered into in connection with the
Project.

          C.  If the net effect of Owner's designation as the selected
subcontractors and suppliers (taking into account both subcontractors and
suppliers whose bids exceed those of bidders recommended by Design/Builder and
those whose bids are less than bidders recommended by Design/Builder) is the
selection of subcontractors and suppliers whose bids, in the aggregate, exceed
those of the bidders recommended by Design/Builder and approved by Owner as
complying with the Drawings and Specifications, the Estimated Design/Builder's
Cost and the Guaranteed Maximum Cost shall be increased by the amount by which
the bids of the designated subcontractors and suppliers exceed the bids of the
bidders recommended by Design/Builder.  Design/Builder's Fee set forth in
Section IX hereof shall not be increased on account of Owner's designation of
subcontractors or suppliers, regardless of the number of such designations or
the resulting increase in the Guaranteed Maximum Cost, if any.

          D.  All subcontracts shall, so far as practicable, contain unit prices
and any other feasible formula for use in the determination of the cost of
changes in the Work.  Design/Builder agrees to hold all subcontractors,
including all persons directly or indirectly employed by them, responsible for
any damages due to breach of contract or any negligent act and to diligently
endeavor to effect recoveries of such damages.

          Section XIII.  Insurance and Indemnification
                         -----------------------------

          A.  Design/Builder shall provide Builder's Risk insurance on the terms
and conditions set forth in the General Conditions of the Contract attached
hereto as Exhibit I or in Exhibit C hereto, as applicable.  Design/Builder shall
          ---------       ---------
also provide and cause its subcontractors to provide

hereto, as applicable, and the errors and omissions insurance in an amount of
not less than $1,000,000 of coverage of those providing design services as set
forth in the General Conditions or Exhibit C hereto, as applicable. The costs of
                                   ---------
all such insurance is included in the Estimated Design/Builder's Cost and the
Guaranteed Maximum Cost.

          B.  DESIGN/BUILDER SHALL TO THE FULLEST EXTENT PERMITTED BY LAW
INDEMNIFY, DEFEND AND HOLD HARMLESS DEVELOPER, OWNER AND THE TENANT(S) OF THE
PROJECT, AND THEIR RESPECTIVE AFFILIATES, SUBSIDIARIES RELATED ENTITIES AND THE
PARTNERS, OFFICERS, DIRECTORS, SHAREHOLDERS AND EMPLOYEES THEREOF FROM AND
AGAINST ANY AND ALL CLAIMS, LIABILITIES, LOSSES, DAMAGES, COST OR EXPENSE
(INCLUDING BUT NOT LIMITED TO REASONABLE ATTORNEYS' FEES) ARISING OUT OF,
RESULTING FROM OR OCCURRING IN CONNECTION WITH THE PERFORMANCE OF THE WORK THAT
IS (i) ATTRIBUTABLE TO ANY BODILY OR PERSONAL INJURY, SICKNESS, DISEASE OR DEATH
OF ANY PERSON OR ANY DAMAGE OR INJURY TO OR DESTRUCTION OF REAL OR PERSONAL
PROPERTY (OTHER THAN THE WORK ITSELF) INCLUDING THE LOSS OF USE THEREOF, AND
(ii) CAUSED IN WHOLE OR IN PART BY ANY NEGLIGENT, STRICT LIABILITY OR OTHER ACT
OR OMISSION OF DESIGN/BUILDER, ANY SUBCONTRACTOR OR SUB-SUBCONTRACTOR, THEIR
RESPECTIVE AGENTS OR EMPLOYEES OR ANY OTHER PARTY FOR WHOM ANY OF THEM MAY BE
LIABLE, AND REGARDLESS OF WHETHER SUCH IS CAUSED IN PART BY THE NEGLIGENT STRICT

          Section XIV.  Liens
                        -----

          A.  Design/Builder shall not voluntarily permit any laborer's,
materialmen's, mechanics', or other similar lien to be filed or otherwise
imposed on any part of the Work or the property on which the Work is performed.
If any laborer's, materialmen's, mechanics, or other similar lien or claim
thereof is filed and Design/Builder does not cause such lien to be released and
discharged forthwith or file a bond in lieu thereof, Owner shall have the right
to pay all sums necessary to obtain such release and discharge and deduct all
amounts so paid from the Contract Sum.  Design/Builder shall indemnify and hold
harmless Owner from all claims, losses, demands, causes of action or suits of
whatever nature arising out of any such lien.

          B.  Design/Builder shall and hereby does subordinate any and all
liens, rights and interest (whether choate or inchoate and including, without
limitation, all mechanics' and materialmen's liens under the applicable laws and
statutes of the state of the situs of the project) owned, claimed or held, or to
be owned, claimed or held by Design/Builder or anyone else acting or claiming
through or under Design/Builder in and to any part of the Work or the property
on which the Work is performed, to the liens securing payments of sums now or
hereafter borrowed by Owner in connection with construction of the Improvements.
Design/Builder shall execute such further and additional evidence of the
subordination of any and all liens, rights and interest as Owner's lenders may
require, including the form of Subordination Agreement attached hereto as
Exhibit G. The subordination of lien is made in consideration of and as an
---------
inducement to the execution and delivery of this Agreement, and shall be
applicable despite any dispute between the parties hereto or any others, or any
default by Owner under the Contract Documents or otherwise.

          C.  Design/Builder shall include in every subcontract relating to the
Work (including without limitation the electrical, mechanical, foundation and
excavation, and elevator subcontracts) to which it is a party and in each and
every lower tier subcontract, provisions (i) that the person or entity doing
work, performing labor or furnishing materials pursuant to each subcontract
agrees to subordinate any mechanics' or materialmen's lien or any other claim
against any part of the Work or the property on which the Work is performed for
or on account of any work done, labor performed or materials furnished under the
Contract Documents or such subcontract to the liens securing payment of sums now
or hereafter borrowed by Owner or applicable rights of any industrial or
development district or other governmental or quasi-governmental entity in
connection with construction of the Improvements, (ii) that the required
subordinations are made in consideration of and as an inducement to the
execution and delivery of this Agreement and the subcontract in which it
appears, and shall be applicable despite any dispute between or among Owner,
Design/Builder or any subcontractor or any default by Owner, Design/Builder or
any subcontractor under the Contract Documents or any other subcontract or
agreement and (iii) that Owner and Owner's lenders are express third party
beneficiaries who have supplied consideration for such subordinations.

          Section XV.  Bonds
                       -----

          A.  Design/Builder shall obtain and maintain during the performance of
the Work a performance bond and a labor and material payment bond, with obligee
rider, each in form and substance satisfactory to Owner.  The initial penal sum
for each such bond shall be in an amount equal to the Contract Sum and
thereafter the penal sums will be adjusted to reflect any adjustments to said
Contract Sum.  It is understood by Design/Builder and its surety that the penal
sum will automatically be deemed equal to the Contract Sum as adjusted from time
to time.  To evidence the above automatic adjustments of the penal sums,
Design/Builder shall provide to Owner and Owner's lender on a quarterly basis
(or at such other times as Owner or Owner's lender may request) a written
instrument executed by the surety evidencing such adjustments of the penal sums
for each such bond.  Such bonds shall be issued by independent corporate surety
of recognized financial standing satisfactory to Owner.  The cost of the
premiums for such bonds is included in the Estimated Design/Builder's Cost and
the Guaranteed Maximum Cost. All refunds, credits or dividends, if any, from any
such premiums shall be calculated at Final Payment and shall accrue to Owner.

          B.  Any performance bond or labor and material payment bond furnished
by Design/Builder shall not include, and specifically excludes, the work
included in the Design Contract Scope of Work.

          Section XVI.  Independent Contractor
                        ----------------------

          In performing its obligations hereunder, Design/Builder shall be
deemed an independent contractor and not an agent or employee of Owner.
Design/Builder shall have exclusive authority to manage, direct, and control the
Work.  Owner is interested in only the results obtained and not in the methods
used in achieving the results.

          Section XVII.  Inspection and Audit
                         --------------------

          A.  Design/Builder represents that it has inspected the location of
the Work and has satisfied itself as to the condition thereof and that the
Contract Sum is just and reasonable compensation for all the Work, including all
foreseen or foreseeable risks, hazards, and difficulties in connection
therewith.

          B.  Owner at all times shall have access to the Work for inspection
thereof, but shall not be obligated to conduct any such inspection.
Design/Builder shall provide proper and safe facilities for such access and
inspection.  If any of the Work is required to be inspected or approved by any
public authority, Design/Builder shall cause such inspection or approval to
occur.

          C.  Design/Builder understands and acknowledges that Owner's lenders
require periodic inspection and certification by an independent architect
designated and engaged by lender and by other authorities and agencies.
Design/Builder agrees to make the site available at all reasonable times for
such inspections and shall coordinate with Owner's Representative (as
hereinafter defined) as requested.

                                      27
<PAGE>

          D.  No inspection performed or failed to be performed by Owner
hereunder shall be a waiver of any of Design/Builder's obligations hereunder or
be construed as an approval or acceptance of the Work of any part thereof.

          E.  Design/Builder shall check all materials and labor entering into
the Work and shall keep full and detailed accounts thereof.

          F.  In addition to Owner's other rights with regards to subcontracts
entered into by Design/Builder, Owner shall be permitted to review and audit
such subcontracts and the scope of work set forth therein.  Owner shall have
access to the Work and the right to audit all Design/Builder's books, records,
correspondence, instructions, drawings, receipts, vouchers and memoranda
relating to the Work, and Design/Builder shall preserve all such records for a
period of four (4) years after the Final Payment hereunder.

          G.  It is understood and agreed that this Agreement, the General
Conditions of the Contract includes as Exhibit I hereto and the other Contract
                                       ---------
Documents provide for Owner's review and/or approval of various aspects of the
design, construction and performance of the Work.  Anything to the contrary
expressed or implied by the Contract Documents or otherwise notwithstanding, an
such reviews and approvals shall be solely for the benefit of Owner and may be
exercised or omitted in Owner's sole discretion.  Owner shall have no obligation
to conduct any review or inspection or to express or submit any approval, and
neither the doing so nor the failure to do so shall create or impose any duty,
obligation or liability on Owner.  It is further expressly understood and agreed
that no review, inspection or approval shall create any rights in any
architects, subcontractors or suppliers engaged by Design/Builder or in any
other third parties.

          Section XVIII.  Survey; Record Drawings
                          -----------------------

          A.  Concurrent with the Final Request for Payment, Design/Builder
shall furnish as-built surveys showing the exact locations of all structures and
water, sewer, gas, telephone, cable, cable TV and electric lines and mains and
of all easements for such utilities then existing.  Such surveys shall be
prepared by a licensed surveyor who shall certify that the Improvements are
installed and erected entirely upon the Exhibit A property and within the
                                        ---------
building restriction lines, if any, and do not overhang or encroach upon any
easement or right-of-way of others.

          B.  During the progress of the Work, Design/Builder shall mark record
drawings to show the actual installation where the installation varies
substantially from the Work as originally shown, giving particular attention to
information on concealed elements that would be difficult to measure and record
at a later date. Design/Builder shall submit the marked-up record drawings prior
to Completion, preparing such documents so as to provide Owner with an as-built
set of documents depicting the Project as constructed. Where changes and
information are indicated on shop drawings, Design/Builder shall provided sepias
or vellums of such drawings as supplements to the record drawings. The drawings
shall be reviewed by Owner and returned to Design/Builder with comments.
Design/Builder shall make corrections necessary and submit the originals of the
final drawings to Owner.

                                      28
<PAGE>

          Section IX.  Termination
                       -----------

          A.  If Design/Builder fails to commence the design or construction of
the Work in accordance with the provisions of this Agreement or diligently
prosecute the design or construction of Work to completion thereof in a
diligent, efficient, timely, workmanlike, skillful and careful manner and in
strict accordance with the provisions of the Contract Documents (including the
Scheduled Completion Date), to use an adequate amount or quality of personnel or
equipment to complete the Work without undue delay, to perform any of its
obligations under the Contract Documents, or to make prompt payments to its
subcontractors, materialmen or laborers, then Owner shall have the right, if
Design/Builder shall not cure any such default after seven (7) days written
notice thereof (or, if such default is of such a nature as to be incapable of
cure within such period, shall not commence action to cure said default within
such period and thereafter diligently and continuously pursue such action to
complete such cure promptly, and in all events within thirty (30) days of such
notice), to (i) terminate this Agreement, (ii) take possession of and use all or
any part of Design/Builder's materials, equipment, supplies, and other property
of every kind used by Design/Builder in the performance of the Work and to use
such property in the completion of the Work, or (iii) complete the design and
construction of the Project in any manner it deems desirable, including engaging
the services of other parties therefor.  Any such act by Owner shall not be
deemed a waiver of any other right or remedy of Owner.  If after exercising any
such remedy the cost to Owner of the performance of the balance of the Work is
in excess of the unpaid portion of the Contract Sum, Design/Builder shall be
liable for and reimburse Owner such excess.

          B.  If Owner fails to perform any of its obligations hereunder,
Design/Builder shall have the right to give Owner written notice thereof,
stating the nature of the default.  If Owner does not cure such default within
thirty (30) days after receipt of such notice, Design/Builder shall have the
right to terminate this Agreement by giving Owner written notice thereof at any
time thereafter while such default remains uncured and payment shall be made to
Design/Builder for all Work executed and for any proven loss sustained upon any
materials, equipment, tools, construction equipment and machinery, and
reasonable demobilization costs and fee earned to date of termination.

          C.  Owner may, if Design/Builder neglects to prosecute the Work
properly or to perform any provision of the Contract Documents, or otherwise
does, or omits to do, anything whereby safety or proper construction may be
endangered or whereby damage or injury may result to person or property, after
three (3) days written notice to Design/Builder, without prejudice to any other
remedy Owner may have, make good all work, material, omissions or deficiencies,
and may deduct the cost therefor from the Contract Sum, but no action taken by
Owner hereunder shall affect any of the other rights or remedies of Owner
granted by this Agreement or by law or relieve Design/Builder from any
consequences or liabilities arising from such acts or omissions.

          D.  It is recognized that if Design/Builder is adjudged a bankrupt, or
makes a general assignment for the benefit of creditors, or if a receiver is
appointed for the benefit of its creditors, or if a receiver is appointed on
account of its insolvency, such could impair or frustrate Design/Builder's
performance of this Agreement.  Accordingly, it is agreed that upon the

                                      29
<PAGE>

occurrence of any such event, Owner shall be entitled to request of
Design/Builder or its successor in interest adequate assurance of future
performance in accordance with the terms and conditions hereof. Failure to
comply with such request within ten (10) days of delivery of the request shall
entitle Owner to terminate this Agreement and to the accompanying rights set
forth above in Section XIX(A). In all events pending receipt of adequate
assurance of performance and actual performance in accordance therewith, Owner
shall be entitled to proceed with the Work with its own forces or with other
contractors on a time and material or other appropriate basis the cost of which
will be backcharged against the Contract Sum hereof.

          E.  Owner hereby reserves the right to terminate this Agreement
without regard to fault or breach upon written notice to Design/Builder,
effective immediately unless otherwise provided in said notice.  In the event of
such termination, Owner shall pay as the sole amount due to Design/Builder in
connection with the Project (i) costs reimbursable hereunder for Work performed
to date plus Design/Builder's Fee on such costs (except retainage sums shall not
be paid prior to thirty (30) days following the date of termination); and (ii)
reasonable cost of termination.  Such sums will be due and payable on the same
conditions as set forth in Section IX hereof, for Final Payment to the extent
applicable.  Upon receipt of such payment, the parties hereto shall have no
further obligations to each other except for Design/Builder's obligations to
perform corrective and/or warranty work and to indemnify Owner as provided in
the Contract Documents for only that work performed prior to the date of
termination.  No fee or other compensation shall be due or payable for
unperformed Work.  Design/Builder agrees that each subcontract and purchase
order will reserve for Design/Builder the same right of termination provided by
this Section XIX(E), and Design/Builder further agrees to require that
comparable provisions be included in all lower tier subcontracts and purchase
orders.

          F.  It is recognized and acknowledged that Owner (of affiliated or
related entities of Owner) by separate agreement(s) has engaged (and may engage)
Contractor as a contractor with respect to one or more other construction
projects.  Accordingly it is hereby agreed that any breach or default by
Contractor under this Agreement, or under any other agreement between Owner (or
affiliated or related entitled of Owner) and Contractor shall also be deemed a
breach or default under any and all agreement(s) between the parties.  It is
further agreed that to the extent such breach or default entitles Owner (or
affiliated or related entitles of Owner) to exercise any particular right or
remedy with respect to one agreement, Owner (or affiliated or related entities
of Owner) shall also be entitled to exercise said right or remedy with respect
to any other agreement(s).

          G.  In the event that termination of Design/Builder or its successor
in interest pursuant to Section XIX(A) or (D) was wrongful, such termination
will be deemed converted to a termination for convenience pursuant to Section
XIX(E) and Design/Builder's remedy for wrongful termination in such event shall
be limited to the recovery of the payments permitted for termination for
convenience as set forth in Section XIX(E).

          H.  The rights and remedies of Owner and Design/Builder under this
Section XIX shall be non-exclusive, and shall be in addition to all the other
remedies available to such parties at law or in equity, subject, however, in the
case of Design/Builder, to the limitations contained in Sections XIX(E) and (F)
and other provisions of this Agreement.

          Section XXI.  Title of Work
                        -------------

          Immediately upon the performance of any part of the Work, as between
Design/Builder and Owner, title thereto shall vest in Owner; provided, however,
the vesting of such title shall not impose any obligations on Owner or relieve
Design/Builder of any of its obligations hereunder.

          Section XXII.  Waiver
                         ------

          No consent or waiver, express or implied, by either party to this
Agreement to or of any breach or default by the other in the performance of any
obligations hereunder shall be deemed or construed to be a consent or waiver to
or of any other breach or default by such party hereunder.  Failure on the part
of any party hereto to complain of any act or failure to act of the other party
or to declare the other party in default hereunder, irrespective of how long
such failure continues, shall not constitute a waiver of the rights of such
party hereunder.  Inspection by, payment by, or tentative approval or acceptance
by Owner or the failure of Owner to perform any inspection hereunder, shall not
constitute a final acceptance of the Work or any part thereof and shall not
release Design/Builder of any of its obligations hereunder.

          Section XXIII.  Conflicts
                          ---------

          In case of conflicts between the provisions of this Agreement, any
ancillary documents executed contemporaneously herewith or prior hereto, or any
other of the Contract Documents, the provisions of this Agreement (including all
exhibits) shall prevail.

          Section XXIV.  Work in Progress
                         ----------------

          A.  Design/Builder shall protect and prevent damage to all unfinished
phases of Work, including but not limited to the protection thereof from damage
by the elements, theft, or vandalism.

          B.  Design/Builder shall use reasonable efforts to complete and make
available portions of the Project for occupancy by Owner or its tenants prior to
the Scheduled Completion Date provided such occupancy does not delay the
Project.  Any such early occupancy shall be pursuant to an appropriate agreement
setting forth (i) responsibility for utility cost; (ii) commencement of warranty
obligations for the portion of the Improvements to be occupied; (iii) insurance
to be maintained by Owner or its tenants and their respective separate
contractors; and (iv) appropriate modification of Design/Builder's obligation to
indemnify Owner for Owner's partial negligence as such indemnity relates to the
area(s) to be occupied.  As portions of the Project are completed and occupied,
Design/Builder shall ensure that continuing construction activity will not
unreasonably interfere with the use or occupancy of the completed portions
thereof. Design/Builder recognizes that Owner and/or its tenant for the Project
will engage other contractors who will be performing other work at and within
the Project, and Design/Builder accepts such ongoing activity as a site
condition relative to its Work, and its schedule, costs and fee include time and
monies associated with performing work in such manner.  Design/Builder will
permit other contractors who are performing tenant work or other work in the
Project access

                                      32
<PAGE>

to the Project and coordinate the Work with the work of such separate
contractors so that the work by such other contractors and the Work under this
Agreement do not interfere with each other.

          Section XXV.  Compliance with Laws
                        --------------------

          Any provisions hereof the contrary notwithstanding, Design/Builder
shall observe and abide by and perform all of its obligations hereunder in
accordance with all applicable laws, rules and regulations of all governmental
authorities having jurisdiction, including the Federal Occupational, Safety and
Health Act, the Americans with Disabilities Act, Texas Accessibility Standards,
and environmental statutes.  Design/Builder shall not transport, store or
introduce to the Project, nor specifically for use in its design or
construction, any hazardous substances, as that term is used in the
promulgations of the Environmental Protection Agency or The Texas Natural
Resources Conservation Commission.

          Section XXVI.  Personnel
                         ---------

          All personnel used by Design/Builder in the performance of the Work
shall be qualified by training and experience to perform their assigned tasks.
At the request of Owner, Design/Builder shall not use in the performance of the
Work any personnel deemed by Owner to be incompetent, careless, unqualified to
perform the work assigned to him, or otherwise unsatisfactory to Owner.  It is
specifically agreed that Design/Builder's Project Manager shall be Damon Norman,
and its Superintendent shall be Ed Gaston. The Project Manager will devote such
time to Work as necessary to properly perform his respective duties to assure
that the Work will be diligently prosecuted in accordance with the Contract
Documents and the Project Manager win continue such role unless prior release is
approved or directed by Owner's Representative.  The Superintendents and other
approved personnel other than the Project Manager will be engaged in the
prosecution of the Work continuously on an exclusive, full time basis until
their role is completed, unless prior release is approved or directed by Owner's
Representative or unless such personnel shall cease to be employed by
Design/Builder.  Replacement of or addition to such key personnel shall
similarly be subject to prior approval by Owner.  Design/Builder further agrees
not to remove from the Work any employee that Owner considers to be necessary
for the proper performance of the Work without the prior approval of Owner.

          Section XXVII.  Design/Builder's Warranties
                          ---------------------------

          Design/Builder represents and warrants that: (i) it is financially
solvent, able to pay its debts as they mature, and possessed of sufficient
working capital to complete this Agreement; (ii) it is able to furnish the
plant, tools, materials, supplies, equipment and labor, and is experienced in
and competent to perform the Work contemplated by this Agreement; (iii) it is
qualified to do the work herein and is authorized to do business in the State
where the Project is located; and (iv) it holds a license, permit or other
special license to perform the services included in this Agreement, as required
by law, or employs or works under the general supervision of the holder of such

                           -------

          A.  Design/Builder shall (i) re-execute any parts of the Work that
fail to conform with the requirements of this Agreement that appear in the
progress of the Work, (ii) remedy any defects in the Work due to faulty
materials or workmanship which appear within a period of two (2) years of
Substantial Completion of the Project, or within such longer period of time as
may be set forth in the Drawings and Specifications or other Contract Documents;
and (iii) replace, repair or restore any parts of the Project or furniture,
fixtures, equipment or other items placed therein (whether by Owner or any other
party) that are injured or damaged by any such parts of the Work that do not

provisions of this Section XXVIII apply to work done by subcontractors of
Design/Builder as well as work done directly by employees of Design/Builder, but
shall not apply to corrective work attributable solely to the acts or omissions
of any separate contractor of Owner.  The cost to Design/Builder of performing

damaged or not done in accordance with the Contract Documents, an equitable
deduction from the Contract Sum shall be made by agreement between
Design/Builder and Owner.  Until such settlement, Owner may withhold such sums
as Owner deems just and reasonable from monies, if any, due Design/Builder.

and not in lieu of any other remedies Owner may have under this Agreement, at
law, or in equity for defective Work.

grant to Owner or such other or additional parties as Owner may specify, a
nonexclusive assignment, of all warranties and guaranties in connection with the
Project, whether given by Design/Builder or any other contractors,
manufacturers, suppliers and vendors of Design/Builder with respect to the
Improvements and any materials used in the construction and installation
thereof. Design/Builder shall obtain with respect to the roof of the Project in
connection with initial construction: (a) a warranty for a period of two years
from the date of Substantial Completion on all labor and materials, and (b) a
warranty for a period of 20 years from the date of Substantial Completion on the
materials.

representatives will not discuss the Material, including any prospective site
locations for the Project with members of the press, brokers or any other

be a sufficient remedy for any breach of this provision of the Agreement and

equitable relief as a remedy for any such remedy for breach.  Such remedy shall
not be deemed to be exclusive remedy for breach of this Agreement but shall be
in addition to all other remedies available at law or equity to Owner.

                      CONTRACTOR'S CONSENT AND AGREEMENT
                      ----------------------------------

          The undersigned ("Contractor") acknowledges the assignment by ________
__________________________________________ ("Owner"), to _______________________
("Lender"), as additional security for the obligations of Owner under a
Construction Loan Agreement ("Loan Agreement") between Owner (as Borrower) and
Lender (as Lender), dated __________________ of Owner's rights (but not Owner's
obligations) under the Construction Contract and any future modifications of the
Construction Contractor change orders ("Contract") between Owner and the
Contractor pertaining to the project contemplated by the Loan Agreement, such
project to be located upon certain real property described on Exhibit "A"
                                                              -----------
attached hereto and made a part hereto (the "Property"). Contractor hereby
consents to such assignment and represents and warrants to and agrees with
Lender as follows:

          1.   The copy of the Contract attached hereto as Exhibit "B" is a
                                                           -----------
true, correct and complete copy of the Contract, the Contract has not been
changed or modified, and the Contract is in full force and effect.

          2.   If Owner defaults under the Loan Agreement, Lender may elect by a
specific request in writing to (i) have Contractor continue performance under
the Contract, in which case Contractor shall thereafter perform under the
Contract pursuant to the remainder of this Paragraph 2, or (ii) have Contractor
stop work on the project and vacate the Property, in which case Contractor shall
promptly do so. If Lender elects by specific request in writing to have
Contractor continue or recommence to perform work under the Contract, Contractor
shall continue or recommence performance on Lender's behalf under the Contract
in accordance with the terms thereof, provided that Contractor shall be
reimbursed in accordance with the Contract requested by Lender following such
notice. Contractor will look solely to the Owner for all sums owing under the
Contract attributable to periods of time prior to the date Contractor begins to
act on Lender's behalf and at Lender's specific request. Contractor's agreement
to act under the Contract for Lender will not depend upon Contractor being paid
any sums owing by the Owner under the Contract prior thereto nor on whether the
Owner has otherwise defaulted under the Contract. Nor will Lender be liable for
any amounts owing Contractor if Lender requests Contractor to stop work and
vacate the Property pursuant to clause (ii) above. lender shall not be liable
for any damages Contractor may be entitled to recover from Owner or for change
orders made by Contractor and not approved by Lender pursuant to the Loan
Agreement. "Lender" as used in this Paragraph includes Lender's successors or
assigns, any receiver in possession of the Property, any purchaser upon
foreclosure of Lender's security, or any corporation or other nominee formed by
or on Lender's behalf (collectively "Lender's Successors"). This Paragraph 2
shall not affect the rights of Lender or Lender's Successors upon or following a
foreclosure or transfer of title to the Property.

          3.   If Owner defaults in making any payment or in performing any
other obligation under the Contract, Contractor shall promptly give Lender
written notice thereof, specifying the default and the steps necessary to cure
same; and if Contractor learns of any default in payment due any subcontractor
or other person supplying labor or materials for the project, Contractor shall
similarly advise the Lender thereof. Contractor will not exercise any remedy
available under the Contract, at law, or in equity arising from such default by
Owner until Lender shall have had the same opportunity to cure such default to
which Owner is entitled, if Lender so elects to cure such default, and such
longer period of time as may be necessary to obtain possession of, or title to,
the Property, provided that Lender shall have no obligation to cure any Owner
default. In the event the Contract provides for a cure period of less than
thirty (30) days in favor of Owner, Lender shall be entitled to cure such
default for a period of at least thirty (30) days notwithstanding such
provision. Any curative act done by Lender shall be as effective as if done by
Owner.

          4.   Contractor shall not perform work under any change order without
first securing Lender's written consent to such change order unless: (a) the
Owner has certified to
<PAGE>

Contractor that Lender's consent is not required for such change order; and (b)
the cost of or reduction resulting from any single change or modification does
not exceed $_____________ and the aggregate amount of all such changes and
modifications does not exceed $_____________. In any such case, Contractor shall
promptly provide Lender or its construction consultant with a copy of such
change order or other modification. lender's consent shall not constitute any
assumption by Lender of any obligation under the Contract. In addition,
Contractor will not amend, modify, or terminate (except as specified below) the
Contract without the prior written consent of Lender, provided that contractor
may terminate the Contract because of a default by Owner thereunder to the
extent Contractor has such right in the Contract, provided Contractor has first
complied with Section 3 above.

          5.   Contractor hereby expressly subordinates all contractual,
constitutional and statutory mechanics' and materialmen's liens to which
Contractor may be or become entitled, to all liens and security interest
securing the loan contemplated by the Loan Agreement and expressly waives any
right to remove any removable improvements from the Property. Contractor shall
require all subcontracts and purchase orders to contain a provision
subordinating the subcontractors' and materialmen's liens to the liens and
security interests securing the loan contemplated by the Loan Agreement and
expressly waiving the right to remove removable improvements from the Property.

          6.   As of the date hereof, Contractor has no counterclaim, right of
set-off, defense or like right against Owner or Lender, and to the best of
Contractor's knowledge and belief, the Owner is not in default under the terms
of the Contract. Contractor is not in default under the terms of the Contract.

          7.   Nothing herein shall be construed to confer any present benefits
on Contractor or to create any contractual arrangement between Contractor and
Lender or to impose upon Lender any duty to see to the application of the
proceeds of the loan contemplated by the Loan Agreement or to give any notice of
any type to Contractor. Contractor acknowledges that Lender is obligated under
the Loan Agreement only to the Owner and to no other person or entity.
Contractor is executing this Consent and Agreement to induce Lender to advance
funds under the Loan Agreement, and Contractor understands that Lender would not
do so but for contractor's execution and delivery of this Consent and Agreement.

          8.   Contractor shall provide Lender promptly in each case with (a)
any information Contractor may have regarding defects in workmanship or
materials incorporated into or provided for the project which come to
Contractor's attention, (b) Contractor's estimate(s) of the stage(s) of
completion of the project, (c) any deviations or variations in construction of
the project from the plans and specifications used by Contractor, (d) any
information Contractor may have regarding any defaults by Owner, or any other
contractor or subcontractor under any construction contracts, and (e) any claims
of non-payment by any person furnishing labor or material in connection with
construction of the project.

          9.   This Agreement shall bind and benefit Contractor, Lender and
their respective successors and assigns, including Lender's Successors, their
successors and assigns.

          10.  Any notice for purposes of this Agreement shall be given in
writing or by telex or by facsimile (fax) transmission and shall be addressed or
delivered to the respective addresses set forth below, or to such other address
as may have been previously designated by the intended recipient by notice given
in accordance with this Section. If sent by prepaid, registered or certified
mail (return receipt requested), the notice shall be deemed effective when the
receipt is signed or when the attempted initial delivery is refused or cannot be
made because of a change of address of which the sending party has not been
notified; if transmitted by telex, the notice shall be effective when
transmitted (answerback) confirmed; and if transmitted by facsimile or personal
delivery, the notice shall be effective when received. Until changed by notice
given in accordance with this Section, the initial respective addresses for

          To Contractor:

          11.  The provisions of this Agreement cannot be waived, modified or
amended unless such waiver, modification or amendment is in writing and is
executed on behalf of each of Lender and Contractor.

          12.  No work of any kind, including the destruction or removal of any
existing improvements, site work, clearing, grubbing, draining or fencing of the
Property, has been commenced or performed on the Property and no equipment or
materials have been delivered to the Property for any purpose whatsoever.

          13.  Neither the Contract, nor any memorandum or affidavit thereof,
has been recorded by or on behalf of Contractor in the county where the Property
is located or in any other county. No affidavit of commencement of construction
of any improvements, performance of labor, furnishing of materials, or providing
of specially fabricated materials in connection with the construction
contemplated by the Contract has been executed or filed by Contractor in the
county where the Property is located or in any other county. Contractor will,
however, join in the execution of such an affidavit once such work has commenced
in form and substance satisfactory to Lender.

          14.  Contractor will address to Lender, naming Lender as an additional
named party or beneficiary, all certificates, statements, or representatives
regarding the completion of the project or any portion thereof.
