<Page>

2.02    COMMENCEMENT OF CONTRACT TIMES; NOTICE TO PROCEED

    A. The Contract Times will commence to run on the day indicated in the
Notice to Proceed. A Notice to Proceed may be given at any time within
one-hundred eighty days after the Effective Date of the Agreement, provided
OWNER has secured financial commitments sufficient to fund the project, to the
satisfaction of the DESIGN/BUILDER.

2.03    STARTING THE WORK

    A. DESIGN/BUILDER shall start to perform the Work on the date when the
Contract Times commence to run.

2.04    BEFORE STARTING CONSTRUCTION

    A. DESIGN/BUILDER shall submit the following for review within ten days
after commencement of the Contract Times:

    1. A preliminary progress schedule indicating the times (numbers of days or
    dates) for starting and completing the various stages of the Work;

    2. A preliminary schedule of required Submittals and the times for
    submitting, reviewing and processing each Submittal;

    3. A preliminary Schedule of Values for all of the Work which will include
    quantities and prices of items aggregating the Contract Price and will
    subdivide the Work into component parts in sufficient detail to serve as the
    basis for progress payments during performance of the Work. Such prices will
    include a pro rata amount of overhead and profit applicable to each item of
    Work; and

    4. A preliminary Cash Flow Projection.

    B. Before any Work is started, DESIGN/BUILDER and OWNER shall each deliver
to the other, with copies to each additional insured, certificates of insurance
(and other evidence of insurance which either of them or any additional insured
may reasonably request) which DESIGN/BUILDER and OWNER respectively are required
to purchase and maintain in accordance with paragraphs 5.02.A, 5.04.A and
5.04.B.

2.05    INITIAL CONFERENCE

    A. Within twenty days after the Contract Times start to run a conference
attended by OWNER and DESIGN/BUILDER and others as appropriate will be held to
establish a working understanding among the parties as to the Work and to
discuss the design concepts, schedules referred to in paragraph 2.04.A,

progress payment shall be made to DESIGN/BUILDER until the schedules are
submitted to and acceptable to OWNER as provided below. The progress schedule
will be acceptable to OWNER as providing an orderly progression of the Work to
completion within the Contract Times, but such acceptance will neither impose on
OWNER responsibility for the sequencing, scheduling or progress of the Work nor
interfere with or relieve DESIGN/BUILDER from DESIGN/BUILDER's full
responsibility therefor. The format and structure of the progress schedule will
be as set forth in the Contract Documents. OWNER's acceptance shall not be
deemed to confirm that the schedule is a reasonable plan for performing the
Work. DESIGN/BUILDER's schedule of Submittals will be

<Page>

acceptable to OWNER as providing a workable arrangement for reviewing and
processing the required Submittals. DESIGN/BUILDER's Schedule of Values and Cash
Flow Projection will be acceptable to OWNER as to form and substance.


ARTICLE 3--CONTRACT DOCUMENTS:  INTENT, AMENDING, REUSE
-------------------------------------------------------------------------------

3.01    INTENT

    A. The Contract Documents comprise the entire agreement between OWNER and
DESIGN/BUILDER concerning the Work. The Contract Documents are complementary;
what is called for by one is as binding as if called for by all. The Contract
Documents will be construed in accordance with the law of the place of the
Project.

    B. It is the intent of the Contract Documents to describe a functionally
complete Project (or part thereof) to be designed and constructed in accordance
with the Contract Documents. Any Work, materials or equipment that may
reasonably be inferred from the Contract Documents or from prevailing custom or
trade usage as being required to produce the intended result will be furnished
and performed whether or not specifically called for. When words or phrases
which have a well-known technical or construction industry or trade meaning are
used to describe work, materials or equipment, such words or phrases shall be
interpreted in accordance with that meaning.

3.02    REFERENCES

    A. Reference to standards, specifications, manuals or codes of any technical
society, organization or association, or to the Laws or Regulations of any
governmental authority, whether such reference be specific or by implication,
shall mean the latest standard, specification, manual, code or Laws or
Regulations in effect on the effective date of the agreement except as may be
otherwise specifically stated in the Contract Documents.

    B. Except as otherwise specifically stated in the Contract Documents or as
may be provided by amendment or supplement thereto issued by one of the methods
indicated in paragraph 3.03.A, the provisions of the Contract Documents shall
take precedence in resolving any conflict, error, ambiguity or discrepancy
between the provisions of the Contract Documents and:

    1. the provisions of any such standard, specification, manual, code or
    instruction (whether or not specifically incorporated by reference in the
    Contract Documents); or

    2. the provisions of any such Laws or Regulations applicable to the
    performance of the Work (unless such an interpretation of the provisions of
    the Contract Documents would result in violation of such Law or Regulation).

    C. No provision of any such standard, specification, manual, code or
instruction shall be effective to change the duties and responsibilities of
OWNER, DESIGN/BUILDER or any of their subcontractors, consultants, agents, or
employees from those set forth in the Contract Documents, nor shall it be
effective to assign to OWNER any duty or authority to supervise or direct the
furnishing or performance of the Work or any duty or authority to undertake
responsibility inconsistent with the provisions of paragraph 8.02 or any other
provision of the Contract Documents.

<Page>

3.03    AMENDING AND SUPPLEMENTING CONTRACT DOCUMENTS

    A. The Contract Documents may be amended to provide for additions, deletions
and revisions in the Work or to modify the terms and conditions thereof in one
or more of the following ways:

    1. OWNER's approval of required Submittals (pursuant to paragraph 6.16.B);

    2. A Work Change Directive;

    3. A Change Order;

    4. A formal Written Amendment; or

    5. A Field Order.

3.04    REUSE OF DOCUMENTS

    A. All documents including Drawings and Specifications prepared or furnished
by DESIGN/BUILDER pursuant to the Contract Documents are instruments of service
in respect of the Project and DESIGN/BUILDER shall retain an ownership and
property interest therein whether or not the Project is completed. OWNER may
make and retain copies for information and reference in connection with the use
and occupancy of the Project by OWNER and others; however, such documents are
not intended or represented to be suitable for reuse by OWNER or others on
extensions of the Project or on any other project. Any reuse without written
verification or adaptation by DESIGN/BUILDER for the specific purpose intended
will be at OWNER's sole risk and without liability or legal exposure to
DESIGN/BUILDER and OWNER shall indemnify and hold harmless DESIGN/BUILDER,
Subcontractors, and Engineer from all claims, damages, losses and expenses
including attorneys' fees arising out of or resulting therefrom. Any such
verification or adaptation will entitle DESIGN/BUILDER to further compensation
at rates to be agreed upon by OWNER and DESIGN/BUILDER.

    B. In addition to paragraph 3.04.A, all documents including Drawings and
Specifications prepared or furnished by DESIGN/BUILDER pursuant to the Contract
Documents are subject to the use and disclosure restrictions set forth in
Exhibit F attached to the Agreement.

ARTICLE 4--AVAILABILITY OF LANDS; DIFFERING SITE CONDITIONS; REFERENCE POINTS;
HAZARDOUS CONDITIONS
-------------------------------------------------------------------------------

4.01    AVAILABILITY OF LANDS

    A. OWNER shall furnish, as indicated in the Contract Documents, the lands
upon which the Construction is to be performed, rights-of-way and easements for
access thereto, and such other lands which are designated for the use of
DESIGN/BUILDER.

    B. Upon reasonable written request, OWNER shall furnish DESIGN/BUILDER with
a correct statement of record legal title and legal description of the lands
upon which the Construction is to be performed and OWNER's interest therein as
necessary for giving notice of or filing a mechanic's lien against such lands in
accordance with applicable Laws and Regulations. OWNER shall identify any
encumbrances or restrictions not of general application but specifically related
to use of lands so furnished with which DESIGN/BUILDER will have to comply in
performing the Work. Easements for permanent structures or permanent changes in
existing facilities will be obtained and paid for by OWNER, unless otherwise
provided in the Contract Documents. If DESIGN/BUILDER and OWNER are unable to
agree on entitlement to or the amount or extent of any adjustments in the
Contract Price or the Contract Times as a result of any delay in OWNER's
furnishing these lands, rights-of-way or easements, DESIGN/BUILDER may make a
claim therefor as provided in Article 9.

<Page>

    C. OWNER shall provide for all additional lands and access thereto that may
be required for temporary construction facilities or storage of materials and
equipment.

4.02    DIFFERING SITE CONDITIONS

    A. DESIGN/BUILDER shall promptly, and before the conditions are disturbed,
give a written notice to OWNER of (i) subsurface or latent physical conditions
at the Site which differ materially from those indicated in the Contract
Documents, or (ii) unknown physical conditions at the Site, of an unusual
nature, which differ materially from those ordinarily encountered and generally
recognized as inhering in work of the character called for by the Contract
Documents.

    B. OWNER will investigate the site conditions promptly after receiving the
notice. If the conditions do materially so differ and cause an increase or
decrease in the DESIGN/BUILDER's cost of, or the time required for, performing
any part of the Work, whether or not changed as a result of the conditions, an
equitable adjustment shall be made under this clause and the Contract Price
and/or Contract Times modified in writing by Change Order in accordance with
Article 9.

    C. No request by DESIGN/BUILDER for an equitable adjustment under paragraph
4.02 shall be allowed unless DESIGN/BUILDER has given the written notice
required; provided that the time prescribed in 9.02.A for giving written notice
may be extended by OWNER.

4.03    REFERENCE POINTS

    A. DESIGN/BUILDER shall be responsible for laying out the construction and
shall protect and preserve the reference points established by OWNER pursuant to
paragraph 8.01.A.6.e and shall make no changes or relocations without the prior
written approval of OWNER. DESIGN/BUILDER shall report to OWNER whenever any
reference point or property monument is lost or destroyed or requires relocation
because of necessary changes in grades or locations, and shall be responsible
for the accurate replacement or relocation of such reference points or property
monuments by professionally qualified personnel.

4.04    Hazardous Conditions

    A. OWNER will be responsible for any Hazardous Condition encountered at the
Site which was not identified in the Contract Documents to be within the scope
of the Work. OWNER shall not be responsible for materials creating a Hazardous
Condition brought to the Site by DESIGN/BUILDER, Subcontractors, Suppliers or
anyone else for whom DESIGN/BUILDER is responsible.

    B. DESIGN/BUILDER and any affected Subcontractor shall immediately (i) stop
all Construction in connection with such Hazardous Condition and in any area
affected thereby (except in an emergency as required by paragraph 6.15), and
(ii) notify OWNER (and thereafter confirm such notice in writing). OWNER shall
promptly determine the necessity of retaining a qualified expert to evaluate
such Hazardous Condition or take corrective action, if any. DESIGN/BUILDER shall
not be required to resume Construction in connection with such Hazardous
Condition or in any such affected area until after OWNER has obtained any
required permits related thereto and delivered to DESIGN/BUILDER special written
notice (i) specifying that such Hazardous Condition and any affected area is or
has been rendered safe for the resumption of Construction, or (ii) specifying
any

<Page>

special conditions under which such Construction may be resumed safely. If OWNER
and DESIGN/BUILDER cannot agree as to entitlement to or the amount or extent of
an adjustment, if any, in Contract Price and/or Contract Times as a result of
such Construction stoppage or such special conditions under which Construction
is agreed by DESIGN/BUILDER to be resumed, either party may make a claim
therefor as provided in Article 9.

    C. If after receipt of such special written notice DESIGN/BUILDER does not
agree to resume Construction based on a reasonable belief it is unsafe, or does
not agree to resume such Construction under such special conditions, then OWNER
may order such portion of the Work that is related to such Hazardous Condition
or in such affected area to be deleted from the Work. If OWNER and
DESIGN/BUILDER cannot agree as to entitlement to or the amount or extent of an
adjustment, if any, in Contract Price and/or Contract Times as a result of
deleting such portion of the Work, then either party may make a claim therefor
as provided in Article 9. OWNER may have such deleted portion of the Work
performed by OWNER's own forces or others in accordance with Article 7.

    D. To the fullest extent permitted by Laws and Regulations, OWNER shall
indemnify and hold harmless DESIGN/BUILDER, Subcontractors, Suppliers, Engineers
and the officers, directors, employees, agents, other consultants and
subcontractors of each and any of them from and against all claims, costs,
losses and damages (including but not limited to all reasonable fees and charges
of engineers, architects, attorneys and other professionals and all court or
arbitration or other dispute resolution costs) arising out of or resulting from
such Hazardous Condition, provided that (i) any such claim, cost, loss or damage
is attributable to bodily injury, sickness, disease or death, or to injury to or
destruction of tangible property (other than completed Construction), including
the loss of use resulting therefrom, and (ii) nothing in this paragraph 4.04.D
shall obligate OWNER to indemnify any individual or entity from and against the
consequences of that individual's or entity's own negligence or willful
misconduct.

5.05    WAIVER OF RIGHTS

    A. OWNER and DESIGN/BUILDER intend that all policies purchased in accordance
with paragraph 5.04 will protect OWNER, DESIGN/BUILDER, Engineers,
Subcontractors, and all other individuals or entities listed as insureds or
additional insureds in such policies and will provide primary coverage for all
losses and damages caused by the perils or causes of loss covered thereby. All
such policies shall contain provisions to the effect that in the event of
payment of any loss or damage the insurers will have no rights of recovery
against any of the insureds or additional insureds thereunder. OWNER and
DESIGN/BUILDER waive all rights against each other and their respective
officers, directors, employees and agents for all losses and damages caused by,
arising out of or resulting from any of the perils or causes of loss covered by
such policies and any other property insurance applicable to the Work; and, in
addition, waive all such rights against Subcontractors, Suppliers, Engineers and
all other individuals or entities listed as insureds or additional insureds
under such policies for losses and damages so caused. None of the above waivers
shall extend to the rights that any party making such waiver may have to the
proceeds of insurance held by OWNER as trustee or otherwise payable under any
policy so issued. In addition, OWNER waives all rights against DESIGN/BUILDER,
Subcontractors, Engineers and Suppliers and the officers, directors, employees
and agents of any of them for business interruption, loss of use of OWNER's
property and any other consequential damages caused by, arising out of or
resulting from any of such insured perils or causes of loss or any other peril
or cause of loss whether or not insured.

5.06    RECEIPT AND APPLICATION OF PROCEEDS

    A. Any insured loss under the policies of insurance required by paragraph
5.04 will be adjusted with OWNER and made payable to OWNER as fiduciary for the
insureds, as their interests may appear, subject to the requirements of any
applicable mortgage clause and of paragraph 5.06.B. OWNER shall deposit in a
separate account any money so received, and shall distribute it in accordance
with such agreement as the parties in interest may reach. If no other special
agreement is reached the damaged Work shall be repaired or replaced, the moneys
so received applied on account thereof and the Work and the cost thereof covered
by an appropriate Change Order or Written Amendment.

    B. OWNER as fiduciary shall have power to adjust and settle any loss with
the insurers unless one of the parties in interest shall object in writing
within fifteen days after the occurrence of loss to OWNER's exercise of this
power. If such objection be made, OWNER as fiduciary shall make settlement with
the insurers in accordance with such agreement as the parties in interest may

ARTICLE 10--CHANGE OF CONTRACT PRICE
--------------------------------------------------------------------------------

10.01   GENERAL

    A. The Contract Price constitutes the total compensation (subject to
authorized adjustments) payable to DESIGN/BUILDER for performing the Work.

    B. The Contract Price may only be changed by a Change Order or by a Written
Amendment. Any claim for an adjustment in the Contract Price shall be based on
written notice delivered by the party making the claim to the other party
promptly in accordance with paragraph 9.02.A.

    C. The value of any Work covered by a Change Order or of any claim for an
adjustment in the Contract Price will be determined as follows:

    1. Where the Work involved is covered by unit prices contained in the
    Contract Documents, by application of such unit prices to the quantities of
    the items involved;

    2. Where the Work involved is not covered by unit prices contained in the
    Contract Documents, by a mutually agreed lump sum (which may include an
    allowance for overhead and profit not necessarily in accordance with
    paragraph 10.02) or by mutually agreed unit prices;

    3. Where the Work involved is not covered by unit prices contained in the
    Contract Documents and agreement to a lump sum is not reached under
    paragraph 10.01.C.2, on the basis of the Cost of the Work (determined as
    provided in paragraph 10.02) plus a DESIGN/BUILDER's Fee for overhead and
    profit (determined as provided in paragraph 10.02.C).

10.02   COST OF THE WORK

    A. COSTS INCLUDED: The term Cost of the Work means the sum of all costs
necessarily incurred and paid by DESIGN/BUILDER in the proper performance of the
Work. Except as otherwise may be agreed to in writing by OWNER, such costs shall
be in amounts no higher than those prevailing in the locality of the Project,
shall include only the following items and shall not include any of the costs
itemized in paragraph 10.02.B:

    1. Payroll costs for employees in the direct employ of DESIGN/BUILDER in the
    performance of the Work under schedules of job classifications agreed upon
    by OWNER and DESIGN/BUILDER.

<Page>

            a. Such employees shall include without limitation superintendents,
        foremen and other personnel employed full-time at the Site. Payroll
        costs for employees not employed full time on the Site shall be
        apportioned on the basis of their time spent on the Site. Payroll costs
        shall include, but not be limited to, salaries and wages plus the cost
        of fringe benefits which shall include social security contributions,
        unemployment, excise and payroll taxes, workers' compensation, health
        and retirement benefits, bonuses, sick leave, vacation and holiday pay
        applicable thereto. The expenses of performing Work after regular
        working hours, on Saturday, Sunday or legal holidays, shall be included
        in the above to the extent authorized by OWNER.

            b. Such employees shall also include engineers and engineering
        technicians providing Design Professional Services. For purposes of this
        paragraph 10.02.A.1, DESIGN/BUILDER shall be entitled to payment for
        such employees an amount equal to salary costs times a factor, both as
        designated in the Agreement, for all services performed or furnished by
        such employees engaged on the Project.

    2. Cost of all materials and equipment furnished and incorporated in the
    Work, including costs of transportation and storage thereof, and Suppliers'
    field services required in connection therewith. All cash discounts shall
    accrue to DESIGN/BUILDER unless OWNER deposits funds with DESIGN/BUILDER
    with which to make payments, in which case the cash discounts shall accrue
    to OWNER. All trade discounts, rebates and refunds and returns from sale of
    surplus materials and equipment shall accrue to OWNER, and DESIGN/BUILDER
    shall make provisions so that they may be obtained.

    3. Payments made by DESIGN/BUILDER to Subcontractors for Work performed or
    furnished by Subcontractors.

    4. Payments made by DESIGN/BUILDER to Engineers for Design Professional
    Services provided or furnished by Engineers under a Design Subagreement.

    5. Costs of special consultants (including but not limited to testing
    laboratories, surveyors, attorneys and accountants) employed for services
    specifically related to the Work.

    6. Supplemental costs including the following items:

            a. The proportion of necessary transportation, travel and
        subsistence expenses of DESIGN/BUILDER's employees incurred in discharge
        of duties connected with the Work.

            b. Cost, including transportation and maintenance, of all materials,
        supplies, equipment, machinery, appliances, office and temporary
        facilities at the Site and hand tools not owned by the workers, which

        of such items used but not consumed which remain the property of
        DESIGN/BUILDER.

            c. Rentals of all Work equipment and machinery and the parts thereof
        whether rented from DESIGN/BUILDER or others in accordance with rental
        agreements approved by OWNER, and the costs of transportation, loading,
        unloading, installation, dismantling and removal thereof--all in
        accordance with the terms of said rental agreements. The rental of any
        such equipment, machinery or parts shall cease when the use thereof is
        no longer necessary for the Work.

            d. Sales, consumer, use or similar taxes related to the Work, and
        for which

<Page>

        DESIGN/BUILDER is liable, imposed by Laws and Regulations.

            e. Deposits lost for causes other than negligence of DESIGN/BUILDER,
        any Subcontractor or anyone directly or indirectly employed by any of
        them or for whose acts any of them may be liable, and royalty payments
        and fees for permits and licenses.

            f. Losses, damages and related expenses caused by damage to the Work
        not compensated by insurance or otherwise, sustained by DESIGN/BUILDER
        in connection with the furnishing and performance of the Work provided
        they have resulted from causes other than the negligence of
        DESIGN/BUILDER, any Subcontractor, or anyone directly or indirectly
        employed by any of them or for whose acts any of them may be liable.
        Such losses shall include settlements made with the written consent and
        approval of OWNER. No such losses, damages and expenses shall be
        included in the Cost of the Work for the purpose of determining
        DESIGN/BUILDER's fee. If, however, any such loss or damage requires
        rework and DESIGN/BUILDER is placed in charge thereof, DESIGN/BUILDER
        shall be paid for services a fee proportionate to that stated in
        paragraph 10.02.C.

            g. The cost of utilities, fuel and sanitary facilities at the Site.

            h. Minor expenses such as telegrams, long distance telephone calls,
        telephone service at the Site, expressage and similar petty cash items
        in connection with the Work.

            i. Cost of premiums for all Bonds and insurance DESIGN/BUILDER is
        required by the Contract Documents to purchase and maintain.

    B. COSTS EXCLUDED: The term Cost of the Work shall not include any of the
following:

    1. Payroll costs and other compensation of DESIGN/BUILDER's officers,
    executives, principals (of partnerships and sole proprietorships), general
    managers, engineers, architects, estimators, attorneys, auditors,
    accountants, purchasing and contracting agents, expediters, timekeepers,
    clerks and other personnel employed by DESIGN/BUILDER whether at the Site or
    in DESIGN/BUILDER's principal or a branch office for general administration
    of the Work and not specifically included in the agreed upon schedule of job
    classifications referred to in paragraph 10.02.A.1 -- all of which are to be
    considered administrative costs covered by the DESIGN/BUILDER's fee.

    2. Expenses of DESIGN/BUILDER's principal and branch offices other than
    DESIGN/BUILDER's office at the Site.

    3. Any part of DESIGN/BUILDER's capital expenses, including interest on
    DESIGN/BUILDER's capital employed for the Work and charges against
    DESIGN/BUILDER for delinquent payments.

    4. Costs due to the negligence of DESIGN/BUILDER, any Subcontractor, or
    anyone directly or indirectly employed by any of them or for whose acts any
    of them may be liable, including but not limited to, the correction of
    DEFECTIVE Work, disposal of materials or equipment wrongly supplied and
    making good any damage to property.

    5. Other overhead or general expense costs of any kind and the costs of any
    item not specifically and expressly included in paragraph 10.02.

<Page>

    C. FEE: The DESIGN/BUILDER's fee allowed to DESIGN/BUILDER for overhead and
profit on Change Orders priced by paragraph 10.01.C.3 shall be determined as
follows:

    1. A mutually acceptable fixed fee; or

    2. If a fixed fee is not agreed upon, then a fee based on the following
    percentages of the various portions of the Cost of the Work:

            a. Materials and equipment, the DESIGN/BUILDER'S fee shall be 15
        percent;

            b. For subcontracts , the DESIGN/ BUILDER's fee shall be five
        percent;

            c. Where one or more tiers of subcontracts are on the basis of Cost
        of the Work plus a fee and no fixed fee is agreed upon, the intent of
        paragraphs 10.02.A.1, 10.02.A.2 and 10.02.A.3 is that the Subcontractor
        who actually performs or furnishes Work, at whatever tier, will be paid
        a fee of 15 percent of the costs incurred by such Subcontractor under
        paragraphs 10.02.A.1 and 10.02.A.2 and that any higher tier
        Subcontractor and DESIGN/BUILDER will each be paid a fee of five percent
        of the amount paid to the next lower tier Subcontractor;

            d. The amount of credit to be allowed by DESIGN/BUILDER to OWNER for
        any change which results in a net decrease in cost will be the amount of
        the actual net decrease in cost plus a deduction in DESIGN/BUILDER's fee
        by an amount equal to five percent of such net decrease; and

            e. When both additions and credits are involved in any one change,
        the adjustment in DESIGN/BUILDER's fee shall be computed on the basis of
        the net change in accordance with paragraphs 10.02.C.2.a through
        10.02.C.2.d, inclusive.

    D. DOCUMENTATION: Whenever the cost of any Work is to be determined pursuant
to paragraph 10.02.A and 10.02.B, DESIGN/BUILDER will establish and maintain
records thereof in accordance with generally accepted accounting practices and
submit in a form acceptable to OWNER an itemized cost breakdown together with
supporting data.

10.03   CASH ALLOWANCES

    A. The Contract Price includes all allowances so named in the Contract
Documents.

        1. The allowances include the cost to DESIGN/BUILDER (less any
    applicable trade discounts) of materials and equipment required by the
    allowances to be delivered at the Site, and all applicable taxes; and

        2. Except as set forth in the Contract Documents, DESIGN/BUILDER's costs
    for unloading and handling on the Site, labor, installation costs, overhead,
    profit and other expenses contemplated for the allowances have been included
    in the Contract Price and not in the allowances and no demand for additional
    payment on account of any of the foregoing will be valid.

    B. Prior to final payment, an appropriate Change Order will be issued to
reflect actual amounts due DESIGN/BUILDER on account of Work covered by
allowances, and the Contract Price shall be correspondingly adjusted.

<Page>

ARTICLE 11--CHANGE OF CONTRACT TIMES
--------------------------------------------------------------------------------

11.01   GENERAL

    A. The Contract Times may only be changed by a Change Order or a Written
Amendment. Any claim for an adjustment of the Contract Times shall be based on
written notice pursuant to paragraph 9.02.

    B. All Contract Times are of the essence of the Agreement.

11.02   TIME EXTENSIONS

    A. Where DESIGN/BUILDER is prevented from completing any part of the Work
within the Contract Times due to delay beyond the control of DESIGN/BUILDER, the
Contract Times will be extended in an amount equal to the time lost due to such
delay if a claim is made therefor as provided in Article 9. Delays beyond the
control of DESIGN/BUILDER shall include, but not be limited to, acts or neglect
by OWNER, governmental agencies, acts or neglect of utility owners or other
contractors performing other construction work as contemplated by Article 7,
fires, floods, epidemics, abnormal weather conditions or acts of God. Delays
attributable to and within the control of a Subcontractor or Supplier shall be
deemed to be delays within the control of DESIGN/BUILDER.

    B. Nothing in this paragraph 11.02 bars a change in Contract Price pursuant
to Article 10 to compensate for the direct costs incurred by DESIGN/BUILDER due
to delay, interference, or disruption directly attributable to actions or
inactions of OWNER. However, OWNER shall not be liable to DESIGN/BUILDER for
costs or damages arising out of or resulting from (i) delays caused by or within
the control of DESIGN/BUILDER, or (ii) delays beyond the control of both parties
including but not limited to fires, floods, epidemics, abnormal weather
conditions, acts of God or acts or neglect by governmental agencies, utility
owners, or other contractors performing other work as contemplated by Article 7.

ARTICLE 12--TESTS AND INSPECTIONS; CORRECTION, REMOVAL OR ACCEPTANCE OF
DEFECTIVE CONSTRUCTION
--------------------------------------------------------------------------------

12.01   NOTICE OF DEFECTS

    A. Prompt written notice of all DEFECTIVE Construction of which OWNER has
actual knowledge will be given to DESIGN/BUILDER by OWNER. All DEFECTIVE
Construction may be rejected, corrected or accepted as provided in this Article
12.

12.02   ACCESS TO CONSTRUCTION

    A. OWNER, other representatives and personnel of OWNER, independent testing
laboratories and governmental agencies with jurisdictional interests will have
access to the Construction at the Site at reasonable times for their
observation, inspecting and testing. DESIGN/BUILDER shall provide them proper
and safe conditions for such access and advise them of DESIGN/BUILDER's Site
safety procedures and programs so that they may comply therewith as applicable.

12.03   TESTS AND INSPECTIONS

    A. If the Contract Documents or Laws or Regulations of any public body
having jurisdiction require any part of the Construction specifically to be
inspected, tested or approved, DESIGN/BUILDER shall assume full responsibility
for arranging and obtaining such inspections, tests or approvals, pay all costs
in connection therewith, and furnish OWNER the required certificates of
inspection or approval. DESIGN/BUILDER shall also be responsible for arranging
and obtaining and shall pay all costs in

<Page>

connection with any inspections, tests or approvals required for OWNER's
acceptance of materials or equipment to be incorporated in the Construction or
of materials, mix designs, or equipment submitted for approval prior to
DESIGN/BUILDER's purchase thereof for incorporation in the Construction.

    B. DESIGN/BUILDER shall give OWNER reasonable notice of the planned schedule
for all required inspections, tests or approvals.

    C. If any Construction (or the construction work of others) that is required
to be inspected, tested or approved is covered by DESIGN/BUILDER without written
concurrence of OWNER, it must, if requested by OWNER, be uncovered for
observation at DESIGN/BUILDER's expense unless DESIGN/BUILDER has given OWNER
timely notice of DESIGN/BUILDER's intention to cover the same and OWNER has not
acted with reasonable promptness in response to such notice.

12.04   UNCOVERING CONSTRUCTION

    A. If any Construction is covered contrary to the written request of OWNER,
it must, if requested by OWNER, be uncovered for OWNER's observation and
recovered at DESIGN/BUILDER's expense.

    B. If OWNER considers it necessary or advisable that covered Construction be
observed by OWNER or inspected or tested by others, DESIGN/BUILDER, at OWNER's
request, shall uncover, expose or otherwise make available for observation,
inspection or testing as OWNER may require, that portion of the Construction in
question, furnishing all necessary labor, material and equipment. If it is found
that such Construction is DEFECTIVE, DESIGN/BUILDER shall pay all costs and
damages caused by or resulting from such uncovering, exposure, observation,
inspection and testing and of satisfactory replacement or rework, (including but
not limited to all reasonable fees and charges of engineers, architects,
attorneys and other professionals, all court or arbitration or other dispute
resolution costs, and all costs of repair or replacement of work of others); and
OWNER shall be entitled to an appropriate decrease in the Contract Price, and,
if the parties are unable to agree as to the amount thereof, may make a claim
therefor as provided in Article 9. If, however, such Construction is not found
to be DEFECTIVE, DESIGN/BUILDER shall be allowed an increase in the Contract
Price or an extension of the Contract Times, or both, directly attributable to
such uncovering, exposure, observation, inspection, testing, replacement and
rework; and, if the parties are unable to agree as to the amount or extent
thereof, DESIGN/BUILDER may make a claim therefor as provided in Article 9.

12.05   OWNER MAY STOP THE CONSTRUCTION

    A. If the Construction is DEFECTIVE, or DESIGN/BUILDER fails to supply
sufficient skilled workers or suitable materials or equipment, or fails to
furnish or perform the Construction in such a way that the completed
Construction will conform to the Contract Documents, OWNER may order
DESIGN/BUILDER to stop Construction or any portion thereof, until the cause for
such order has been eliminated; however, this right of OWNER to stop
Construction will not give rise to any duty on the part of OWNER to exercise
this right for the benefit of DESIGN/BUILDER or any other party.

12.06   CORRECTION OR REMOVAL OF DEFECTIVE CONSTRUCTION

    A. OWNER will have authority to disapprove or reject DEFECTIVE Construction
and will have authority to require special inspection or testing of the

<Page>

Construction whether or not the Construction is fabricated, installed or
completed. If required by OWNER, DESIGN/BUILDER shall promptly, as directed,
either correct all DEFECTIVE Construction, whether or not fabricated, installed
or completed, or, if the Construction has been rejected by OWNER, remove it from
the Site and replace it with nondefective Construction. DESIGN/BUILDER shall
bear all direct, indirect and consequential costs of such correction or removal
(including but not limited to reasonable fees and charges of engineers,
architects, attorneys and other professionals) made necessary thereby.

12.07   CORRECTION PERIOD

    A. If within one year after the date of Substantial Completion or such
longer period of time as may be prescribed by Laws or Regulations or by the
terms of any applicable special guarantee required by the Contract Documents or
by any specific provision of the Contract Documents, any Construction is found
to be DEFECTIVE, DESIGN/BUILDER shall promptly, without cost to OWNER and in
accordance with OWNER's written instructions, (i) correct such DEFECTIVE
Construction, or, if it has been rejected by OWNER, remove it from the Site and
replace it with Construction that is not DEFECTIVE, and (ii) satisfactorily
correct or remove and replace any damage to other Construction or the work of
others resulting therefrom. If DESIGN/BUILDER does not promptly comply with the
terms of such instructions, or in an emergency where delay would cause serious
risk of loss or damage, OWNER may have the DEFECTIVE Construction corrected or
the rejected Construction removed and replaced, and all costs and damages caused
by or resulting from such removal and replacement (including but not limited to
all reasonable fees and charges of engineers, architects, attorneys and other
professionals, all court or arbitration or other dispute resolution costs, and
all costs of repair or replacement of work of others) will be paid by
DESIGN/BUILDER.

    B. In special circumstances where a particular item of equipment is placed
in continuous service before Substantial Completion of all the Construction, the
correction period for that item may start to run from an earlier date if so
provided in the Specifications or by Written Amendment.

    C. Where DEFECTIVE Construction (and damage to other Construction resulting
therefrom) has been corrected, removed or replaced under this paragraph 12.07,
the correction period hereunder with respect to such Construction will be
extended for an additional period of one year after such correction or removal
and replacement has been satisfactorily completed.

12.08   ACCEPTANCE OF DEFECTIVE CONSTRUCTION

    A. If, instead of requiring correction or removal and replacement of
DEFECTIVE Construction, OWNER prefers to accept it, OWNER may do so.
DESIGN/BUILDER shall pay all costs attributable to OWNER's evaluation of and
determination to accept such DEFECTIVE Construction (such costs to include but
not be limited to all reasonable fees and charges of engineers, architects,
attorneys and other professionals and all court or arbitration or other dispute
resolution costs). If any such acceptance occurs prior to final payment, a
Change Order will be issued incorporating the necessary revisions in the
Contract Documents with respect to the Construction; and OWNER shall be entitled
to an appropriate decrease in the Contract Price, and, if the parties are unable
to agree as to the amount thereof, OWNER may make a claim therefor as provided
in Article 9. If the acceptance occurs after final payment, an appropriate
amount will be paid by DESIGN/BUILDER to OWNER.

<Page>

12.09   OWNER MAY CORRECT DEFECTIVE CONSTRUCTION

    A. If DESIGN/BUILDER fails within a reasonable time after written notice
from OWNER to correct DEFECTIVE Construction or to remove and replace rejected
Construction as required by OWNER in accordance with paragraphs 12.06.A or
12.07.A, or if DESIGN/BUILDER fails to perform the Construction in accordance
with the Contract Documents, or if DESIGN/BUILDER fails to comply with any other
material provision of the Contract Documents, OWNER may, after seven days'
written notice to DESIGN/BUILDER, correct and remedy any such deficiency. In
exercising the rights and remedies under this paragraph OWNER shall proceed
expeditiously. In connection with such corrective and remedial action, OWNER may
exclude DESIGN/BUILDER from all or part of the Site, take possession of all or
part of the Construction, and suspend DESIGN/BUILDER's services related thereto,
and incorporate in the Construction all materials and equipment stored at the
Site or elsewhere for which OWNER has paid DESIGN/BUILDER. DESIGN/BUILDER shall
allow OWNER, OWNER's representatives, agents and employees, OWNER's other
contractors and consultants access to the Site to enable OWNER to exercise the
rights and remedies under this paragraph. All costs and damages incurred or
sustained by OWNER in exercising such rights and remedies will be charged
against DESIGN/BUILDER and a Change Order will be issued incorporating the
necessary revisions in the Contract Documents and OWNER shall be entitled to an
appropriate decrease in the Contract Price, and, if the parties are unable to
agree as to the amount thereof, OWNER may make a claim therefor as provided in
Article 9. Such costs and damages will include but not be limited to all
reasonable fees and charges of engineers, architects, attorneys and other
professionals, all court or arbitration or other dispute resolution costs and
all costs of repair or replacement of work of others destroyed or damaged by
correction, removal or replacement of DESIGN/BUILDER's DEFECTIVE Construction.
DESIGN/BUILDER shall not be allowed an extension of the Contract Times because
of any delay in the performance of the Construction attributable to the exercise
by OWNER of OWNER's rights and remedies hereunder.


ARTICLE 13--PAYMENTS TO DESIGN/BUILDER AND COMPLETION
--------------------------------------------------------------------------------

13.01   SCHEDULE OF VALUES

    A. The Schedule of Values established as provided in paragraph 2.06.A will
serve as the basis for progress payments and will be incorporated into a form of
Application for Payment acceptable to OWNER.

<Page>

13.02   APPLICATION FOR PROGRESS PAYMENT

    A. At least twenty days before the date established for each progress
payment (but not more often than once a month), DESIGN/BUILDER shall submit to
OWNER for review an Application for Payment filled out and signed by
DESIGN/BUILDER covering the Work completed as of the date of the Application and
accompanied by such supporting documentation as is required by the Contract
Documents. If payment is requested on the basis of materials and equipment not
incorporated in the Work but delivered and suitably stored at the Site or at
another location agreed to in writing, the Application for Payment shall also be
accompanied by a bill of sale, invoice or other documentation warranting that
OWNER has received the materials and equipment free and clear of all Liens and
evidence that the materials and equipment are covered by appropriate property
insurance and other arrangements to protect OWNER's interest therein, all of
which will be satisfactory to OWNER. The amount of retainage with respect to
progress payments will be as stipulated in the Agreement.

13.03   DESIGN/BUILDER'S WARRANTY OF TITLE

    A. DESIGN/BUILDER warrants and guarantees that title to all construction
materials and equipment covered by any Application for Payment, whether
incorporated in the Project or not, will pass to OWNER no later than the time of
payment free and clear of all Liens. This paragraph 13.03.A does not apply to
any documents covered by paragraph 3.04.A.

13.04   PROGRESS PAYMENTS

    A. Progress payments shall be made by the OWNER to the DESIGN/BUILDER
according to the following procedure:

        1. OWNER will, within ten days of receipt of each Application for
    Payment, either indicate in writing its acceptance of the Application and
    state that the Application is being processed for payment, or return the
    Application to DESIGN/BUILDER indicating in writing its reasons for refusing
    to accept the Application. Not more than ten days after accepting such
    Application the amount will become due and when due will be paid by OWNER to
    DESIGN/BUILDER.

        2. If the OWNER should fail to pay the DESIGN/BUILDER at the time the
    payment of any amount becomes due, then DESIGN/BUILDER may, at any time
    thereafter, upon serving written notice that DESIGN/BUILDER will stop the
    Work within seven days after receipt of the notice by the OWNER, and after
    such seven day period, stop the Work until payment of the amount owing has
    been received. Written notice shall be deemed to have been duly served if
    sent by certified mail to the last known business address of the OWNER.

        3. Payments due but unpaid shall bear interest at the rate specified in
    the Agreement.

        4. No Progress Payment nor any partial or entire use or occupancy of the
    Project by the OWNER shall constitute an acceptance of any Work not in
    accordance with the Contract Documents.

    B. OWNER may refuse to make the whole or any part of any such payment, or
because of subsequently discovered evidence or the results of subsequent
inspections or tests, nullify any previous payment, to the extent that is
reasonably necessary to protect OWNER from loss because:

    1. The Work is DEFECTIVE, or completed Work has been damaged requiring
    correction or replacement; or

    2. The Contract Price has been reduced by Written Amendment or Change Order;
    or

<Page>

    3. OWNER has been required to correct DEFECTIVE Work or complete Work in
    accordance with paragraph 12.09.A, or

    4. OWNER has actual knowledge of the occurrence of any of the events
    enumerated in paragraphs 14.02.A.1 through A.3 inclusive; or

    5. Claims have been made against OWNER on account of DESIGN/BUILDER's
    performance or furnishing of the Work; or

    6. Liens have been filed in connection with the Work, except where
    DESIGN/BUILDER has delivered a specific Bond satisfactory to OWNER to secure
    the satisfaction and discharge of such Liens.


13.05   SUBSTANTIAL COMPLETION

    A. When DESIGN/BUILDER considers the Construction ready for its intended use
DESIGN/BUILDER shall notify OWNER in writing that the Construction is
substantially complete (except for items specifically listed by DESIGN/BUILDER
as incomplete) and request that OWNER issue a certificate of Substantial
Completion. Within a reasonable time thereafter, OWNER and DESIGN/BUILDER shall
make an inspection of the Construction to determine the status of completion. If
OWNER does not consider the Construction substantially complete, OWNER will
notify DESIGN/BUILDER in writing giving the reasons therefor. If OWNER considers
the Construction substantially complete, OWNER will prepare and deliver to
DESIGN/BUILDER a certificate of Substantial Completion which shall fix the date
of Substantial Completion. There shall be attached to the certificate a list of
items to be completed or corrected before final payment. At the time of delivery
of the certificate of Substantial Completion OWNER will deliver to
DESIGN/BUILDER a written determination as to division of responsibilities
pending final payment between OWNER and DESIGN/BUILDER with respect to security,
operation, safety, maintenance, heat, utilities, insurance and warranties and
guarantees.

    B. OWNER will have the right to exclude DESIGN/BUILDER from the Site after
the date of Substantial Completion, but OWNER will allow DESIGN/BUILDER
reasonable access to complete or correct items on the list of items to be
completed.

13.06   FINAL INSPECTION

    A. Upon written notice from DESIGN/BUILDER that the entire Construction or
an agreed portion thereof is complete, OWNER will make a final inspection with
DESIGN/BUILDER and will notify DESIGN/BUILDER in writing of all particulars in
which this inspection reveals that the

<Page>

Construction is incomplete or DEFECTIVE. DESIGN/BUILDER shall immediately take
such measures as are necessary to complete such Construction or remedy such
deficiencies.

13.07   FINAL APPLICATION FOR PAYMENT

    A. After DESIGN/BUILDER has completed all such corrections to the
satisfaction of OWNER and delivered in accordance with the Contract Documents
all maintenance and operating instructions, schedules, guarantees, Bonds,
certificates or other evidence of insurance required by paragraph 5.08.B,
certificates of inspection, marked-up record documents (as provided in paragraph
6.11) and other documents, DESIGN/BUILDER may make application for final payment
following the procedure for progress payments. The final Application for Payment
shall be accompanied (unless previously delivered) by: (i) all documentation
called for in the Contract Documents, including but not limited to the evidence
of insurance required by subparagraph 5.02.B.7, (ii) consent of the surety, if
any, to final payment, and (iii) complete and legally effective releases or
waivers (satisfactory to OWNER) of all Liens arising out of or filed in
connection with the Work. In lieu of such releases or waivers of Liens and as
approved by OWNER, DESIGN/BUILDER may furnish receipts or releases in full and
an affidavit of DESIGN/BUILDER that: (i) the releases and receipts include all
labor, services, material and equipment for which a Lien could be filed, and
(ii) all payrolls, material and equipment bills and other indebtedness connected
with the Work for which OWNER or OWNER's property might in any way be
responsible have been paid or otherwise satisfied. If any Subcontractor or
Supplier fails to furnish such a release or receipt in full, DESIGN/BUILDER may
furnish a Bond or other collateral satisfactory to OWNER to indemnify OWNER
against any Lien.

13.08   FINAL PAYMENT AND ACCEPTANCE

    A. If OWNER is satisfied that the Work has been completed and
DESIGN/BUILDER's other obligations under the Contract Documents have been
fulfilled, OWNER will, within ten days after receipt of the final Application
for Payment, give written notice to DESIGN/BUILDER that the Work is acceptable.
Otherwise, OWNER will return the Application to DESIGN/BUILDER, indicating in
writing the reasons for refusing to process final payment, in which case
DESIGN/BUILDER shall make the necessary corrections and resubmit the
Application. Thirty days after the presentation to OWNER of the acceptable
Application and accompanying documentation, in appropriate form and substance
and with OWNER's notice of acceptability, the amount will become due and will be
paid by OWNER to DESIGN/BUILDER.

    B. If, through no fault of DESIGN/BUILDER, final completion of the Work is
significantly delayed, OWNER shall, upon receipt of DESIGN/BUILDER's final
Application for Payment, and without terminating the Agreement, make payment of
the balance due for that portion of the Work fully completed and accepted. If
the remaining balance to be held by OWNER for Work not fully completed or
corrected is less than the retainage stipulated in the Agreement, and if Bonds
have been furnished as required in paragraph 5.01.A, the written consent of the
surety to the payment of the balance due for that portion of the Work fully
completed and accepted shall be submitted by DESIGN/BUILDER to OWNER with the
Application for such payment. Such payment shall be made under the terms and
conditions governing final payment, except that it shall not constitute a waiver
of claims.

<Page>

13.09   WAIVER OF CLAIMS

    A.  The making and acceptance of final payment will constitute:

    1. A waiver of all claims by OWNER against DESIGN/BUILDER, except claims
    arising from unsettled Liens, from DEFECTIVE Construction appearing after
    final inspection pursuant to paragraph 13.06, from failure to comply with
    the Contract Documents or the terms of any special guarantees specified
    therein, or from DESIGN/BUILDER's continuing obligations under the Contract
    Documents; and

    2. A waiver of all claims by DESIGN/BUILDER against OWNER other than those
    previously made in writing and still unsettled.

ARTICLE 14--SUSPENSION OF WORK AND TERMINATION
--------------------------------------------------------------------------------

14.01   OWNER MAY SUSPEND WORK

    A. At any time and without cause, OWNER may suspend the Work or any portion
thereof for a period of not more than 90 days by notice in writing to
DESIGN/BUILDER which will fix the date on which Work will be resumed.
DESIGN/BUILDER shall resume the Work on the date so fixed. DESIGN/BUILDER shall
be allowed an adjustment in the Contract Price or an extension of the Contract
Times, or both, directly attributable to any such suspension if DESIGN/BUILDER
makes a claim therefor as provided in Article 9.

14.02   OWNER MAY TERMINATE FOR CAUSE

    A. The occurrence of any one or more of the following events justifies
termination for cause:

        1. DESIGN/BUILDER persistently fails to perform the Work in accordance
    with the Contract Documents (including, but not limited to, failure to
    supply sufficient skilled workers or suitable materials or equipment or
    failure to adhere to the progress schedule established under paragraph
    2.06.A as revised from time to time.

        2. DESIGN/BUILDER disregards Laws or Regulations of any public body
    having jurisdiction.

        3. DESIGN/BUILDER otherwise violates in any substantial way any material
    provisions of the Contract Documents.

    B. OWNER may, after giving DESIGN/BUILDER (and the surety, if any) written
notice of the occurrence of an event in paragraph 14.02.A and twenty days
therefrom to remedy such event, and to the extent permitted by Laws and
Regulations, terminate the services of DESIGN/BUILDER, exclude DESIGN/BUILDER
from the Site and take possession of the Work incorporate in the Work all
materials and equipment stored at the Site or elsewhere for which OWNER has paid
DESIGN/BUILDER and finish the Work as OWNER may deem expedient. In such case
DESIGN/BUILDER shall not be entitled to receive any further payment until the
Work is finished. If the unpaid balance of the Contract Price exceeds all costs,
losses and damages sustained by OWNER arising out of or resulting from
completing the Work (including but not limited to all reasonable fees and
charges of engineers, architects, attorneys and other professionals and all
court or arbitration or other dispute resolution costs) such excess will be paid
to DESIGN/BUILDER. If such costs, losses and damages exceed such unpaid balance,
DESIGN/BUILDER shall pay the difference to OWNER. Such costs, losses and damages
incurred by OWNER will be incorporated in a Change Order, provided that when
exercising any rights or remedies under this paragraph OWNER shall be required
to obtain a reasonable price for the Work performed.

<Page>

    C. Where DESIGN/BUILDER's services have been so terminated by OWNER, the
termination will not affect any rights or remedies of OWNER against
DESIGN/BUILDER then existing or which may thereafter accrue. Any retention or
payment of moneys due DESIGN/BUILDER by OWNER will not release DESIGN/BUILDER
from liability.

14.03   OWNER MAY TERMINATE FOR CONVENIENCE

    A. Upon twenty days' written notice to DESIGN/BUILDER, OWNER may, without
cause and without prejudice to any other right or remedy of OWNER, elect to
terminate the Agreement. In such case, DESIGN/BUILDER shall be paid (without
duplication of any items) for:

    1. Completed and acceptable Work executed in accordance with the Contract
    Documents prior to the effective date of termination, including fair and
    reasonable sums for overhead and profit on such Work;

    2. Expenses sustained prior to the effective date of termination in
    performing services and furnishing labor, materials or equipment as required
    by the Contract Documents in connection with uncompleted Work, plus fair and
    reasonable sums for overhead and profit on such expenses;

    3. Amounts paid in settlement of terminated contracts with Subcontractors,
    Engineers, Suppliers and others (including but not limited to all fees and
    charges of engineers, architects, attorneys and other professionals and all
    court or arbitration or other dispute resolution costs incurred in
    connection with termination of contracts with Subcontractors, Engineers and
    Suppliers); and

    4. Reasonable expenses directly attributable to termination.

    B. DESIGN/BUILDER shall not be paid on account of loss of anticipated
profits or revenue or other economic loss arising out of or resulting from such
termination.

    C. In the event OWNER decides not to complete the Project after terminating
the Agreement under paragraph 14.03.A., then OWNER shall promptly return to
DESIGN/BUILDER any and all written documents that include Proprietary Property
(as defined in Exhibit F of the Agreement). In the event the OWNER decides to
complete the Project, OWNER shall pay to DESIGN/BUILDER, in addition to the
amounts set forth in paragraph 14.03.A., the unpaid portion, if any, of the
license fee for the Proprietary Property that is included in the Contract Price.
Unless otherwise agreed in writing by the parties, the license fee included in
the Contract Price is $2,000,000.00.

14.04   DESIGN/BUILDER MAY STOP WORK OR TERMINATE

    A. If, through no act or fault of DESIGN/BUILDER, the Work is suspended for
a period of more than ninety days by OWNER or under an order of court or other
public authority, or OWNER fails to act on any Application for Payment within
thirty days after it is submitted or OWNER fails for thirty days to pay
DESIGN/BUILDER any sum finally determined to be due, then DESIGN/BUILDER may,
upon seven days' written notice to OWNER, and provided OWNER does not remedy
such suspension or failure within that time, terminate the Agreement and recover
from OWNER payment on the same terms as provided in paragraph 14.03.A. In lieu
of terminating the Agreement and without prejudice to any other right or remedy,
or OWNER has failed for thirty days to pay DESIGN/BUILDER any sum finally
determined to be due, DESIGN/BUILDER may upon seven day's

<Page>

written notice to OWNER stop the Work until payment is made of all such amounts
due DESIGN/BUILDER, including interest thereon. The provisions of this paragraph
14.04.A are not intended to preclude DESIGN/BUILDER from making claim under
Article 9 for an increase in Contract Price or Contract Times or otherwise for
expenses or damage directly attributable to DESIGN/BUILDER's stopping Work as
permitted by this paragraph.

ARTICLE 15--DISPUTE RESOLUTION
--------------------------------------------------------------------------------

15.01   DISPUTE RESOLUTION AGREEMENT

      A. OWNER and DESIGN/BUILDER agree that they will first submit any and all
unsettled claims, counterclaims, disputes and other matters in question between
them arising out of or relating to the Contract Documents or the breach thereof
("disputes"), to mediation by a mutually agreeable, impartial mediator, or if
the parties cannot so agree, a mediator designated by the American Arbitration
Association ("AAA") pursuant to its Construction Industry Mediation Rules, prior
to either of them initiating against the other a demand for arbitration pursuant
to paragraph 15.01.B through 15.01.E, unless delay in initiating arbitration
would irrevocably prejudice one of the parties. Any time limits within which to
file a demand for arbitration shall be suspended with respect to a dispute
submitted to mediation within those same applicable time limits and shall remain
suspended until 10 days after the termination of the mediation. The mediator of
any dispute submitted to mediation under this Agreement shall not serve as
arbitrator of such dispute unless otherwise agreed.

    B. All claims, disputes and other matters in question between OWNER and
DESIGN/BUILDER arising out of or relating to the Contract Documents or the
breach thereof (except for claims which have been waived by the making or
acceptance of final payment as provided by paragraph 13.10) will be decided by
binding arbitration in accordance with the Construction Industry Arbitration
Rules of the AAA then in effect, subject to the limitations of this paragraph
15.01. This agreement so to arbitrate and any other agreement or consent to
arbitrate entered into in accordance herewith as provided in this paragraph
15.01 will be specifically enforceable under the prevailing law of any court
having jurisdiction.

    C. Notice of the demand for arbitration will be filed in writing with the
other party to the Agreement and with the designated arbitration entity. The
demand for arbitration will be made within a reasonable time after the claim,
dispute or other matter in question has arisen, and in no event shall any such
demand be made after the date when institution of legal or equitable proceedings
based on such claim, dispute or other matter in question would be barred by the
applicable statute of limitations.

    D. Except as provided in paragraph 15.01.E below, no arbitration arising out
of or relating to the Contract Documents shall include by consolidation, joinder
or in any other manner any other individual or` entity who is not a party to
this contract unless:

    1. the inclusion of such other individual or entity is necessary if complete
    relief is to be afforded among those who are already parties to the
    arbitration, and

    2. such other individual or entity is substantially involved in a question
    of law or fact which is common to those who are already parties to the
    arbitration and which will arise in such proceedings, and

    3. the written consent of the other individual or entity sought to be
    included and of OWNER and DESIGN/BUILDER has been obtained for such
    inclusion, which consent shall make specific reference to this paragraph;
    but no such consent shall constitute consent to arbitration of any dispute
    not specifically described in such consent

<Page>

     or to arbitration with any party not specifically identified in such

                           WESTERN PLAINS ENERGY, LLC


EXHIBIT B

GENERAL PROJECT SCOPE

Construct a 30 million gallon per year (MGY) dry mill fuel ethanol plant near
Campus, KS. The plant will grind approximately 10.7 million bushels per year to
produce approximately 30 MGY year of fuel grade ethanol denatured with five
percent gasoline. The plant will also produce approximately 96,000 tons per year
of 10% moisture dried distillers grains with solubles (DDGS) and approximately
89,000 tons per year of raw carbon dioxide (CO2) gas.

Arriving grain will be dumped into a double hopper operated dump pit in a
receiving building. Maximum truck dump time is five minutes. Truck drivers will
start the grain system, dump the grain and obtain a weigh ticket from the scale
operator. A 15,000-bushel per hour leg will lift the corn to a scalper to remove
rocks and debris before conveying the product to one of two 100,000-bushel
storage bins. A dust collection system with bag house will be installed on the
grain receiving system to limit particulate emissions as described in the Air
Quality Permit application.

Ground corn will be mixed in a 17,000-gallon slurry tank, routed through a
4,000-gallon pressure vessel and steam flashed of in a flash vessel. Cooked mash
will continue through two 35,000-gallon liquefaction tanks and into one of three
500,000-gallon fermenters. Simultaneously, propagated yeast will be added to the
mash as the fermenter is filling. After batch fermentation is complete, the beer
will be pumped to the 500,000 gallon beer well and then to the beer column to
vaporize the alcohol from the mash.

Alcohol streams are dehydrated in the distillation column, the side stripper and
the molecular sieve system. Two hundred proof alcohol is pumped to the tank farm
shift tanks and blended with five percent alcohol as the product is being pumped
into a 500,000 gallon final storage tank. Loading facilities for truck and rail
cars will be provided. Tank farm tanks include: one 40,000 gallon for 190 proof
storage, two 40,000 gallon for 200 proof storage, one 40,000 gallon for
denaturant storage. All tanks are covered carbon steel tanks with one floating
roof as required by the air quality permit.

Corn mash from the beer stripper is dewatered in one of three decanter type
centrifuges. Wet cake from the centrifuge is conveyed to the DDGS dryer system.
Water in the thin stillage is evaporated and recycled by the Bio-Methanation
system. Syrup is added to the wet cake entering the dryer. DDGS is pneumatically
conveyed to flat storage in the DDGS storage building. Shipping is accomplished
by scooping and pushing the product with a front-end loader into an in-floor
conveyor system.

Fresh water for the boilers, cooking and other processes will be obtained from
area process wells that will supply the needs of the plant. Boiler water
conditioned in regenerative softeners will be pumped through a deaerator
scrubber and into a deaerator tank. Appropriate boiler chemicals will be added
as preheated water is sent to the boiler.

DESIGN/BUILDER has also developed and patented a process to thermal oxidize the
exhaust gases from both Dryer A and Dryer B. This process will remove over 75%
of the VOCs and particulate that is in the dryer exhaust. The energy required to
complete thermo oxidation will then be ducted to a waste heat boiler that will
produce 100% of the steam requirements of the ethanol plant. The exhaust gases
from the waste heat boiler will be ducted through two stack gas economizers to
recover the maximum amount of energy possible from the exhaust gas stream. After
the economizers, the gas stream will be vented to the atmosphere. The Thermo
Oxidizer waste heat boiler combination is designed to operate in conjunction
with the drying system or independent of the drying system. This will allow for
plant startups and shutdowns without affecting either dryer operation or steam
production capabilities. Both dryers can bypass the Thermo Oxidizer unit and
vent directly to atmosphere on an emergency basis.

The design includes a compressed air system consisting of two 75 Hp compressors,
a receiver tank, pre-filter, coalescing filter and air dryer.

The design also incorporates the use of a clean-in-place (CIP) system for
cleaning cook, fermentation, distillation, evaporation, centrifuges and other
systems. Fifty percent caustic soda is received by truck and stored in one
12,000-gallon tank. The CIP system uses four 12,000 gallon tanks for receiving,
make-up, CIP return and waste CIP which is fed to the methanator. A screener is
used to remove the solids.

Under normal operating circumstances, the plant will not have any wastewater
discharges of water that has been in contact with corn, corn mash, cleaning
system or contact process water. An DESIGN/BUILDER/Phoenix Bio-Methanator will
reduce the organic acids in process water allowing complete reuse within the
plant. The plant will have blowdown discharges from the cooling tower and
boiler.

Most plant processes are computer controlled by a Siemens/Moore APACS
distributed control system with graphical user interface and three workstations.
It is estimated that the system will consist of 200 discrete inputs, 200
discreet outputs, 175 analog inputs and 120 analog outputs. Additional
programmable logic controllers (PLCs) will control certain process equipment.

The plant design may require additional programs to ensure safety and to satisfy
regulatory authorities.

                  PROPRIETARY PROPERTY except for the limited license granted to
                  OWNER.

                           OWNER shall not pay any separate license fee or
                  royalty to DESIGN/BUILDER for OWNER's continual use of the
                  PROPRIETARY PROPERTY pursuant to the limited license granted
                  to OWNER, the consideration for this license is included in
                  the price payable to DESIGN/BUILDER under the Agreement.

                           OWNER's failure to materially comply with the
                  OPERATING PROCEDURES shall void all performance guarantees and
                  warranties set forth in the AGREEMENT relating to the
                  PROPRIETARY PROPERTY, if any. OWNER agrees to defend,
                  indemnify and hold harmless DESIGN/BUILDER against all losses,
                  damages and expenses, including reasonable attorney's fees,
                  incurred as a result of or related to claims of third persons
                  arising out of or related in any way to OWNER's use of the
                  PROPRIETARY PROPERTY.

                           The limited license granted to OWNER shall not be
                  assigned or sublicensed, in whole or in part, without the
                  prior written consent of DESIGN/BUILDER, which consent will
                  not be unreasonably withheld. Failure to obtain such consent
                  prior to OWNER's assignment or sublicense shall be grounds for
                  termination of the limited license granted to OWNER.

                           The PROPRIETARY PROPERTY is confidential and
                  proprietary. OWNER shall keep the PROPRIETARY PROPERTY
                  confidential, and shall use all reasonable efforts to maintain
                  the PROPRIETARY PROPERTY as secret and confidential. OWNER
                  shall not at any time without DESIGN/BUILDER's prior written
                  consent, copy, duplicate, record or otherwise reproduce the
                  PROPRIETARY PROPERTY, in whole or in part, or otherwise make
                  the same available to any unauthorized person. OWNER agrees
                  that DESIGN/BUILDER would be irreparably damaged by reason of
                  any violation of the confidentiality provisions contained
                  herein and that any remedy at law for a breach of such
                  provisions would be inadequate. Therefore, DESIGN/BUILDER
                  shall be entitled to seek injunctive or other equitable relief
                  in a court of competent jurisdiction against OWNER, its
                  agents, employees, affiliates, partners, members,
                  stockholders, officers or other associates, for any breach or
                  threatened breach of the confidentiality covenants contained
                  herein without the necessity of proving actual monetary loss.
                  It is expressly understood that the remedy described herein
                  shall not be the exclusive remedy of DESIGN/BUILDER for any
                  breach of such covenants, and DESIGN/BUILDER shall be entitled
                  to seek such other relief or remedy, at law or in equity, to
                  which it may be entitled as a consequence of any breach of
                  such covenants.

The foregoing provisions are part of, and incorporated into, the Agreement and
should be interpreted consistently therewith. In the event any of the foregoing
provisions is contrary to any provision in the Agreement (or any other document
referenced therein), the foregoing provision shall supercede and have precedence
over such contrary provision.
