Section 6.4

	 	Intentionally Omitted.

Additional Capital Contributions — Calls by Members.
	
 
	 	 

If the Manager should at any time determine that to meet the Company’s cash requirements (x),
the Company is in need of any funds in excess of amounts: available to the Company from (i) cash
flow, (ii) reserves set forth in any Operating Budget or otherwise approved by the Executive
Committee, (iii) any loans approved by the Executive Committee made to the Company to fulfill such

the Additional Capital Contribution required hereunder within the time period required under
Section 6.5 hereof, such Member shall be a Non-Contributing Member hereunder, and the other Member

to it immediately upon its demand and, upon such reimbursement, the Non-Contributing Member’s
failure to contribute shall be deemed cured and such Member shall no longer be considered a
Non-Contributing Member).

Non-Contributing Member, an amount equal to the amount which the Non-Contributing Member has failed
to contribute to the capital of the Company, and the amount so paid by the Contributing Member on
its own behalf and on behalf of the Non-Contributing Member shall (x) constitute a loan to the
Company (a “Member Loan”). Any such loan to the Company shall be transferable to an
Affiliate of the Contributing Member at any time and shall bear interest on the unpaid principal
balance thereof at an annual rate (compounding monthly) equal to the lesser of (A) the then maximum
rate permitted on such debts under the laws of the State of Delaware, or (B) six percent (6%) over
the Prime Rate in effect on the date on which the Contributing Member makes such loan; provided,
however, that the Prime Rate shall be adjusted and determined on the last day of each calendar
month while any part of such loan or any interest accrued thereon remains outstanding, and such
loan shall bear interest on the unpaid principal balance thereof from the first day of the next
succeeding calendar month through the last day of such next succeeding calendar month at an annual
rate (compounding monthly) equal to the lesser of (I) the then maximum rate permitted on such debts
under the laws of the State of Missouri or (II) six percent (6%) over the Prime Rate as so
determined. Notwithstanding the provisions of Articles 8 and 10 hereof, and any other provision
hereof to the contrary, until any such loan and all interest accrued thereon has been paid to the
Contributing Member making such loan, no distributions of cash, in liquidation or otherwise, shall
be made by the Company to the Members, and all such distributions to which the Members would
otherwise be entitled under this Agreement shall be distributed by the Company to the Contributing
Member making such loan and shall be applied first to the payment of all accrued and unpaid
interest on such loan and then to the payment of the principal amount of any such loan.

Section 6.7 Return of Contributions.

Except as expressly provided herein, no Member shall be entitled to the return of (a) any part
of its Capital Contributions, (a) any interest in respect of any Capital Contribution, or (b) the

If the Company shall have insufficient cash to pay its obligations, any Member, with the
approval of the Executive Committee, may advance such funds for the Company on such terms and
conditions as the lending Member and the Executive Committee shall determine. Each such advance
shall constitute a loan from such Member to the Company and shall not constitute a Capital
Contribution.

Section 6.9 Balances.

The Company’s books and records shall contain entries indicating the type and amount of
Capital Contributions made to the Company.

Section 6.10 No Third-Party Rights.

Nothing contained in this Article 6, nor any other provision of this Agreement shall be
construed to create any rights or benefits in any Person, other than the Members, and their
respective legal representatives and permitted transferees, successors and assigns, subject to the
limitations on transfer contained herein.

Section 6.11 Member Loans for Guaranty Payments. Notwithstanding anything contained herein to
the contrary, in the event that Holdings (or Grubb & Ellis Healthcare REIT, Inc., a Maryland

losses, costs or expenses, including, without limitation, actual and reasonable attorneys fees or
expenses, under or related to the Holdings Guaranty or Duke shall make a payment to the lender of
the Project Loan or otherwise incur any damages, losses, costs or expenses, including, without
limitation, actual and reasonable attorneys fees or expenses, under or related to the Duke Guaranty
(a “Guaranty Payment”), then (a) the amount of such Guaranty Payment by Holdings or Grubb &
Ellis Healthcare REIT, Inc. shall constitute a Member Loan to the Company by Holdings and (b) the
amount of such Guaranty Payment by Duke shall constitute a Member Loan to the Company by Duke
(either a “Guaranty Payment Member Loan”). Any Guaranty Payment Member Loan shall be
treated in the same manner as other Member Loans except as follows: (i) Guaranty Payment Member
Loans shall be paid prior to the payment of any other Member Loans and (ii) Guaranty Payment Member
Loans made by Duke shall be payable prior to payments of Guaranty Payment Member Loans made by

	 	[Intentionally Omitted]

Capital Accounts.
	
 
	 	 

(a) Establishment and Maintenance. A separate capital account (“Capital
Account”) will be maintained for each Member. The Capital Account of each Member will be
determined and adjusted as follows:

(1) Each Member’s Capital Account will be credited with the amount of cash and Gross
Asset Value, as agreed by the Members, of any property (net of liabilities assumed by the
Company resulting from such contribution and liabilities to which the property is subject)
contributed by a Member to the Company, the Member’s distributive share of Profits, any items
in the nature of income or gain that are specially allocated to the Member under Section

(2) Each Member’s Capital Account will be debited with the amount of cash and the Gross
Asset Value of any Company property distributed to the Member under any provision of this
Agreement, the Member’s distributive share of Losses, any items in the nature of deduction or

any property contributed by the Member to the Company.

(3) If any Membership Interest is Transferred in accordance with the terms of this
Agreement, the transferee will succeed to the Capital Account of the transferor to the extent
it relates to the transferred Membership Interest.

(b) Modifications by Manager. The provisions of this Section 9.2 and the other
provisions of this Agreement relating to the maintenance of Capital Accounts have been included in
this Agreement to comply with Section 704(b) of the Code and the Regulations promulgated
thereunder and will be interpreted and applied in a manner consistent with those provisions. The
Manager may modify the manner in which the Capital Accounts are maintained under this Section 9.2
to comply with those provisions, as well as upon the occurrence of events that might otherwise
cause this Agreement not to comply with those provisions; however, without the unanimous consent
of all Members, the Manager may not make any modification to the way Capital Accounts are
maintained if such modification would have the effect of changing the amount of distributions to
which any Member would be entitled during the operation, or upon the liquidation, of the Company.

Section 9.3 Adjustment of Gross Asset Value.

“Gross Asset Value.” with respect to any asset, is the adjusted basis of that asset
for federal income tax purposes, except as follows:

(a) The initial Gross Asset Value of any asset contributed (or deemed contributed under Code
Sections 704(b) and 752 and the Regulations promulgated thereunder) by a Member to the Company
will be, subject to Section 6.3, the fair market value of the asset on the date of the
contribution, as detailed on Exhibit A or as otherwise determined by the Executive
Committee.

(b) The Gross Asset Values of all Company assets will be adjusted to equal the respective
fair market values of the assets, as determined by the Executive Committee, as of (1) the
acquisition of an additional interest in the Company by any new or existing Member in exchange for
more than a de minimis capital contribution, (2) the distribution by the Company to a Member of
more than a de minimis amount of Company property as consideration for an interest in the Company
if an adjustment is necessary or appropriate to reflect the relative economic interests of the
Members in the Company, and (3) the liquidation of the Company within the meaning of Regulations
Section 1.704-1(b)(2)(ii)(g).

(c) The Gross Asset Value of any Company asset distributed to any Member will be the gross
fair market value of the asset on the date of distribution.

(d) The Gross Asset Values of Company assets will be increased or decreased to reflect any
adjustment to the adjusted basis of the assets under Code Section 734(b), 732(d) or 743(b), but
only to the extent that the adjustment is taken into account in determining Capital Accounts under
Regulations Section 1.704-1(b)(2)(iv)(m), provided that Gross Asset Values will not be adjusted
under this Section 9.3(d) to the extent that the Manager determines that an adjustment under
Section 9.3(b) is necessary or appropriate in connection with a transaction that would otherwise
result in an adjustment under this Section 9.3(d).

(e) After the Gross Asset Value of any asset has been determined or adjusted under Section
9.3(a), Section 9.3(b) or Section 9.3(d), Gross Asset Value will be adjusted by the Depreciation
taken into account with respect to the asset for purposes of computing Profits or Losses.

Section 9.4 Profits, Losses and Distributive Shares of Tax Items.

(a) Profits. After giving effect to the special allocations in Sections 9.4(c)
and 9.4(d), Profits for any fiscal year shall be allocated to the Members so as to reduce,
proportionately, the differences between their respective Target Capital Accounts and
Partially Adjusted Capital Accounts for such fiscal year. No portion of Profits for any
fiscal year shall be allocated to a member whose Partially Adjusted Capital Account is
greater than or equal to its Target Capital Account for such fiscal year.

(b) Losses. After giving effect to the special allocations in Sections 9.4(c)
and 9.4(d), Losses for any taxable year shall be allocated to the Members so as to reduce,
proportionately the differences between their respective Partially Adjusted Capital Accounts
and Target Capital Accounts for such fiscal year. No portion of the Losses for any fiscal
year shall be allocated to a Member whose Target Capital Account is greater than or equal to
its Partially Adjusted Capital Account for such fiscal year.

(c) Special Allocations. The following special allocations will be made in the
following order and priority before determinations and allocations of Profits and Losses:

(1) Company Minimum Gain Chargeback. If there is a net decrease in Company
Minimum Gain during any taxable year or other period for which allocations are made, before
any other allocation under this Agreement, each Member will be specially allocated items of
Company income and gain for that period (and, if necessary, subsequent periods) in
proportion to, and to the extent of, an amount equal to such Member’s share of the net
decrease in Company Minimum Gain during such year determined in accordance with Regulations
Section 1.704-2(g)(2). The items to be allocated will be determined in accordance with
Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 9.4(c)(1) is intended to
comply with the minimum gain chargeback requirements of the Regulations, and will be
interpreted consistently with the Regulations.

(2) Member Nonrecourse Debt Minimum Gain Chargeback. If there is a net
decrease in Member Nonrecourse Debt Minimum Gain with respect to a Member Nonrecourse Debt
during any taxable year or other period for which allocations are made, any Member with a
share of such Member Nonrecourse Debt Minimum Gain (determined under Regulations Section
1.704-2(i)(5)) will be specially allocated items of Company income and gain for that period
(and, if necessary, subsequent periods) in an amount equal to such Member’s share of the net
decrease in the Member Nonrecourse Debt Minimum Gain during such year determined in
accordance with Regulations Section 1.704-2(i)(4). The items to be so allocated will be
determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This
Section 9.4(c)(2) is intended to comply with the minimum gain chargeback requirements of the
Regulations Section 1.704-2(f) and will be interpreted consistently with the Regulations.

(3) Qualified Income Offset. A Member who unexpectedly receives any
adjustment, allocation or distribution described in Regulations Sections
1.704-1(b)(2)(ii)(d)(4), (5) or (6) will be specially allocated items of Company income and
gain in an amount and manner sufficient to eliminate, to the extent required by the
Regulations, the Adjusted Capital Account Deficit of the Member as quickly as possible.

(4) Nonrecourse Deductions. Nonrecourse Deductions for any taxable year or
other period for which allocations are made will be allocated among the Members in
proportion to their respective Sharing Ratios in the Company.

(5) Member Nonrecourse Deductions. Notwithstanding anything to the contrary in
this Agreement, any Member Nonrecourse Deductions for any taxable year or other period for
which allocations are made will be allocated to the Member who bears the economic risk of
loss with respect to the Member Nonrecourse Debt to which the Member Nonrecourse Deductions
are attributable in accordance with Regulations Section 1.704-2(i).

(6) Code Section 754 Adjustments. To the extent an adjustment to the adjusted
tax basis of any Company asset under Code Sections 734(b) or 743(b) is required to be taken
into account in determining Capital Accounts under Regulations Section 1.704-1(b)(2)(iv)(m),
the amount of the adjustment to the Capital Accounts will be treated as an item of gain (if
the adjustment increases the basis of the asset) or loss (if the adjustment decreases the
basis), and the gain or loss will be specially allocated to the Members in a manner
consistent with the manner in which their Capital Accounts are required to be adjusted under
Regulations Section 1.704-1(b)(2(iv)(m).

(7) The allocations of Profit and Loss and items thereof in this Article 9 are intended
to produce Capital Accounts for the Members that would equal the amounts each Member would
receive if the Company were liquidated, all of the assets of the Company were sold for their
Gross Asset Values and the proceeds were distributed in accordance with Section 10.2(c)(2).
If at any time that is not the case, the Manager is authorized to make special allocations of
items of income, gain, loss and expense until the Members’ Capital Accounts equal the amounts
each Member would receive if the Company were liquidated, all of the assets of the Company
were sold for their Gross Asset Values and the proceeds were distributed in accordance with
Section 10.2(c)(2).

(d) Curative Allocations. The allocations set forth in Section 9.4(c) (the
“Regulatory Allocations”) are intended to comply with certain requirements of Regulations
Sections 1.704-1(b) and 1.704-2. The Regulatory Allocations may effect results which would be
inconsistent with the manner in which the Members intend to divide Company distributions.
Accordingly, the Manager is authorized to divide other allocations of Profits, Losses, and other
items among the Members, to the extent that they exist, so that the net amount of the Regulatory
Allocations and the special allocations to each Member is zero. The Manager will have discretion
to accomplish this result in any reasonable manner that is consistent with Code Section 704 and
the related Regulations.

(e) Tax Allocations-Code Section 704(c). For federal, state and local income tax
purposes, Company income, gain, loss, deduction or expense (or any item thereof) for each fiscal
year shall be allocated to and among the Members to reflect the allocations made pursuant to the
provisions of this Section 9.4 for such fiscal year. In accordance with Code Section 704(c) and
the related Regulations, income, gain, loss and deduction with respect to any property contributed
to the capital of the Company, solely for tax purposes, will be allocated among the Members so as
to take account of any variation between the adjusted basis to the Company of the property for
federal income tax purposes and the initial Gross Asset Value of the property (computed in
accordance with Section 9.3). If the Gross Asset Value of any Company asset is adjusted under
Section 9.3(b), subsequent allocations of income, gain, loss and deduction with respect to that
asset will take account of any variation between the adjusted basis of the asset for federal
income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and
the related Regulations, using the so-called “traditional method.”. Allocations under this
Section 9.4(e) are solely for purposes of federal, state and local taxes and will not affect, or
in any way be taken into account in computing, any Member’s Capital Account or share of Profits,
Losses or other items or distributions under any provision of this Agreement.

(f) Solely for purposes of determining a Member’s proportionate share of the “excess
nonrecourse liabilities” of the Company within the meaning of Regulations Section 1.752-3(a)(3),
the Members’ interests in Company profits are in proportion to their Sharing Ratios

(g) Members shall be bound by the provisions of this Section 9.4 in reporting their shares of
Company income and loss for income tax purposes.

Section 9.5 Tax Returns.

The Manager or its designee shall prepare and file all necessary federal and state income tax
returns for the Company to be prepared prior to their due dates, including making the elections

transferee during such calendar year; however, such allocation shall be made in accordance with a
method permissible under section 706 of the Code and the Regulations thereunder.

Section 9.9 Restrictions on Company Activities.

It is mutually agreed and understood that certain actions, if taken by the Company, could have
seriously adverse tax or other economic consequences to the Members. In order to avoid such
consequences, notwithstanding any other provision of this Agreement, the Members hereby agree as
follows:

(a) The Members acknowledge that Duke Realty Corporation is an Affiliate of Duke and is a
real estate investment trust (a “REIT”) and that Duke Realty Corporation’s ability to
maintain its status as a REIT may be affected by the nature of the income and assets of the
Company. So long as Duke or any Affiliate of Duke is a REIT, unless authorized by the express
terms of this Agreement: (i) except with the express written consent of Duke, the Company shall
not take any action which (a) could, in the reasonable judgment of Duke, adversely affect the
ability of Duke Realty Corporation to continue to qualify as a REIT, or (b) could, in the
reasonable judgment of Duke, subject Duke Realty Corporation to any additional taxes under Section
857 or Section 4981 of the Code; (ii) except with the express written permission of Duke, no
services shall be provided directly by the Company to, or for the benefit of, tenants of the
Property unless such services are provided by a “taxable REIT subsidiary” as defined in Section
856(l) of the Code or an “independent contractor” as defined in Section 856(d)(3) of the Code with
respect to Duke Realty Corporation. The Members agree to discuss the types of services that might
be provided directly by the Company to, or for the benefit of, tenants of the Property and to
jointly determine (1) which services, if any, shall be so provided to, or for the benefit of,
tenants of the Company, and (2) whether the Members or their Affiliates should form a jointly
owned taxable REIT subsidiary to provide any such services and appropriate charges for any
services provided by a taxable REIT subsidiary.

(b) So long as Duke or any Affiliate of Duke is a REIT: (i) without the prior approval of
Duke, the Company shall neither acquire, nor own, directly or indirectly, any “securities” other
than securities that constitute real estate assets within the meaning of Code Section
856(c)(5)(B), Government securities, or securities that are not considered securities pursuant to
Section 856(m), (ii) any securities held by the Company in violation of the preceding clause (i)
shall be deemed for all purposes to be held in trust by the Company for the benefit of Holdings,
and shall not be an asset of the Company; and (iii) the Company shall immediately distribute such
excess securities to Holdings, and Holdings hereby acknowledges and agrees that it will pay an
amount of cash to Duke equal to Duke’s then-Sharing Ratio in the Company multiplied by the fair
market value of such excess securities, as determined by an appraisal process as set forth in
Subsection 9.9(f) hereof, and that the Company will pay all of the expenses associated with the
appraisal process.

(c) Without the prior approval of both Members, the Company shall not elect to be treated as
other than a partnership for federal, state and local tax purposes.

(d) Without the prior approval of both Members, the Company shall not actively market and
hold for sale subdivided lots or condominium units.

(e) If an appraisal is required pursuant to Subsection 9.9(b) hereof, such appraisal shall be
conducted by a committee of three (3) appraisers, each of whom shall be an MAI appraiser, chosen
as follows: one (1) such appraiser shall be chosen by Duke, the second appraiser shall be chosen
by Holdings and the third appraiser shall be chosen by the two (2) appraisers chosen as aforesaid.
If either party does not select an appraiser within ten (10) days of the date of the election and
direction from the other party to so select an appraiser, then the appraiser chosen by the other
party shall be solely responsible for determining such fair market value. Each appraiser shall
make an independent appraisal, and, if there is more than one (1) appraiser, the fair market value
shall be the average of the two (2) appraisals closer in value. Each appraiser shall file its
appraisal with the Company within twenty (20) days of its being retained hereunder

warranties concerning the assets of the Company. In addition, traditional real estate closing
prorations shall be made, and the Put Purchase Price payable to Duke shall be increased or

otherwise complied with the provisions of this Article 13 but Holdings shall fail to pay (or cause
to be paid by the Company) the full amount of the Put Purchase Price to Duke by the Put Closing
Date, then Duke shall have the option to pursue and action to specifically enforce the obligations

by the unamimous consent of the Executive Committee, or, in the event unanimous consent is not
reached, by a committee of appraisers, each of whom shall be an MAI appraiser, chosen as follows:
Within ten (10) days after the date of Holdings’ receipt of the Put Notice one (1) such appraiser
shall be chosen by Duke and a second appraiser shall be chosen by Holdings. If either party does
not select an appraiser within said ten (10) day period, then the appraiser chosen by the other
party shall be solely responsible for determining such Fair Market Value. Each appraiser shall
make an independent appraisal, and, if there is more than one (1) appraiser, the fair market value
shall be the average of the two (2) appraisals if the higher appraisal is in an amount which is
less than 105% of the amount of the lower appraisal. If the amounts of the higher appraisal is in
an amount which is greater than 105% of the amount of the lower appraisal, then a third appraiser
shall be chosen by the two (2) appraisers initially chosen (such selection to be made within ten
(10) days of the date it is determined that the first two appraisals are not close enough to
average) and the appraisal of such third appraiser shall determine the Fair Market Value of the
Property. Each appraiser shall file its appraisal with the Company within twenty (20) days of its
being retained hereunder.

2.1 Loan. Concurrently with Closing and in accordance with the terms of the
Operating Agreement, the Company shall obtain debt financing of approximately 60% of the Agreed
Value (the “Loan”).

Section 3. Earnest Money.

3.1 Earnest Money. Holdings has deposited with Escrow Agent, the Earnest
Money, which is being held pursuant to the terms of the Original Escrow Agreement. On the Contract
Date, Duke, Holdings and Escrow Agent shall execute the New Escrow Agreement. Upon delivery of the
New Escrow Agreement, the Original Escrow Agreement shall be of no further force and effect and
shall replaced in its entirety by the New Escrow Agreement. All Earnest Money, together with any
interest or other income earned thereon, shall be held, invested and disbursed pursuant to the New
Escrow Agreement.

3.2 Disbursement. In the event the Property is contributed to the Company
by Duke, the Earnest Money shall be applied at Closing as part of the Holdings Capital Contribution

unless otherwise disbursed pursuant to this Agreement. Whenever the Earnest Money is by the terms
hereof to be disbursed by Escrow Agent, Duke and Holdings agree promptly to execute and deliver
such notice or notices as shall be reasonably necessary to authorize Escrow Agent to make such
disbursement.

Section 4. Prorations and Adjustments. At the Closing, Holdings and Duke
shall prorate all items of income and expense relating to the Property based upon Holdings’ and
Duke’s respective interests in the Company and periods of ownership for the calendar year in which
the Closing occurs on a cash basis (i.e. based solely upon amounts payable in the year in which
Closing occurs regardless of when they accrue), with the Company treated as the owner of the
Property on the Closing Date, including, without limitation:

4.1 Rent.

4.1.1 Closing. Except as provided in subparagraph (ii) below, Duke shall
pay or credit to the Company (with respect to periods from and after the Closing Date), if, as and
when the same shall be received: (A) all Rent paid by Tenant under the Lease for the calendar
month in which the Closing occurs, prorated for the number of days during such calendar month from,
including and after the Closing, and (B) all prepaid and overpaid Rent of Tenant under the Lease.

4.1.2 Post-Closing. After Closing, Holdings, as Managing Member of the
Company shall make diligent good faith efforts to collect all unpaid Rent for any period prior to
the Closing, provided that Holdings shall have no obligation to institute litigation or terminate
the Lease in connection with any such collections. Any Rent due and owing Duke before the Closing
Date by Tenant under the Lease that is unpaid at the Closing, is herein called “Delinquent Rent”.
There shall be no cash credit to Duke at Closing on account of any Delinquent Rent, but following
Closing, rental and other payments received by the Company, Holdings or Duke from Tenant shall be
first applied toward payment of the Rent for the month in which the Closing occurs, then to any
Rent due to the Company after the Closing and finally toward the payment of Delinquent Rent.
Company shall reasonably cooperate with Duke in any collection of Delinquent Rent.

4.1.3 Tenant Improvements and Leasing Commissions. At or prior to Closing,
Duke shall pay any leasing commissions and tenant improvement costs due and payable on or before
the Closing Date, if any.

4.2 Real Estate Taxes. At or prior to Closing, Duke shall pay all 2007
real estate taxes that are due and payable. The amount of $169,822.00 paid by Duke for 2007 real
estate taxes is not capitalized as Rent and shall be reimbursed directly to Duke by Tenant and
treated as Delinquent Rent.

4.3 Leasing Commissions. At or prior to Closing, Duke shall pay any leasing
commissions due and payable on or before the Closing Date. The Company shall pay any leasing
commissions due and payable in connection with any expansion or renewal after the Closing Date.

4.4 Miscellaneous Prepaid Items. Any prepaid items, including, without
limitation, fees for licenses which are transferred to the Company at the Closing and annual permit
and inspection fees will be prorated as of the Closing Date.

4.5 Closing Statement. Duke shall prepare and deliver to Holdings no later
than three (3) Business Days prior to the Closing Date an estimated closing statement which shall
set forth all costs payable, and the prorations and credits provided for in this Agreement and to
the extent Duke does not timely deliver the estimated closing statement to Holdings, Holdings shall
have the right, but not the obligation, to extend the Closing Date by the number of days Duke is
delinquent in delivering such estimated closing statement to Holdings. Any item which cannot be
finally prorated because of the unavailability of information shall be tentatively prorated on the
basis of the best data then available and adjusted when the information is available in accordance
with this subsection. Holdings shall notify Duke within two (2) days after its receipt of such
estimated closing statement of any items which Holdings disputes, and the parties shall attempt in
good faith to reconcile any differences not later than one (1) day before the Closing Date. The
estimated closing statement as adjusted as aforesaid and approved in writing by the parties (which
shall not be withheld if prepared in accordance with this Agreement) shall be referred to herein as
the “Closing Statement”. If the prorations and credits made under the Closing Statement shall
prove to be incorrect or incomplete for any reason, then either party shall be entitled to an
adjustment to correct the same; provided, however, that any adjustment shall be made, if at all,
within sixty (60) days after the Closing Date (except with respect to taxes, in which case such
adjustment shall be made within thirty (30) days after the information necessary to perform such
adjustment is available), and if a party fails to request an adjustment to the Closing Statement by
a written notice delivered to the other party within the applicable period set forth above (such
notice to specify in reasonable detail the items within the Closing Statement that such party
desires to adjust and the reasons for such adjustment), then the prorations and credits set forth
in the Closing Statement shall be binding and conclusive against such party.

4.6 Items Not Prorated. Duke and Holdings agree that (a) on the Closing
Date, the Property will not be subject to any financing, except the Loan; and (b) none of the
insurance policies relating to the Property will be assigned to the Company and the Company shall
be responsible for arranging for its own insurance as of the Closing Date.

4.7 Closing Costs. Holdings and Duke shall share the following costs and
expenses in accordance with their Percentage Interests: the cost of any updates to the Existing
Survey, the cost of owner’s and lender’s title insurance policies and all title policy endorsements
(whether for owner’s or lender’s policies), all escrow or closing agent charges, all costs
associated with the recording of the Deed and any documents related to the Loan, costs and expenses
incurred in connection with the Loan, and all transfer taxes, if any. Holdings shall pay all costs
of Holdings’ due diligence. Each party shall pay its own attorneys (except for those fees
associated with the Loan negotiation which will be a Company expense). The obligations of the
parties to pay the foregoing costs and expenses shall survive the termination of this Agreement.

	 	 	 
	4.8Survival. The provisions of this Section 4 shall survive the Closing.

	 

	Section 5.

	 	Title and Survey
	
 
	 	 

5.1 Duke will cause Title Insurer to issue an Extended Coverage ALTA Owner’s Policy
of Title Insurance (the “Title Policy”) for and on behalf of Company in the total amount of
the Agreed Value and obtainable at standard rates insuring title in and to the Real Property.
Holdings hereby acknowledges that Duke has heretofore delivered the Existing Survey and the Title
Commitment to Holdings. Holdings shall have until the Inspection Date (the “Title Review Period”)
to (a) examine title to the Property and the updated Survey, (ii) determine whether Holdings will
be able to obtain any endorsements it desires on behalf of the Company and (iii) to give written
notice to Duke of any objections that Holdings may have to title or the Survey (the “Title
Objection Notice”), provided Holdings shall have no right to object to any matters of title which
constitute Permitted Title Exceptions. If Holdings shall fail to timely deliver the Title
Objection Notice, Holdings shall be deemed to have waived such right to object to any title
exceptions or other conditions or matters which are shown on the Survey. If Holdings does timely
deliver the Title Objection Notice to Duke, Duke shall elect, by written notice delivered to
Holdings within three (3) Business Days following Duke’s receipt of the Title Objection Notice (the
"Cure Response Period”) to either endeavor to cure or satisfy any particular objection(s) at or
prior to Closing or not to so cure or satisfy any particular title objection(s) (the “Title
Response Notice”). To the extent Duke shall fail to deliver the Title Response Notice to Holdings
prior to the expiration of the Cure Response Period or shall elect not cure any particular title
objection(s) by Closing, then Holdings may elect, by written notice to Duke within the earlier of
(x) five (5) Business Days after delivery of the Title Response Notice or (y) the expiration of the
Cure Response Period, either to (a) terminate this Agreement, in which case the Earnest Money shall
be returned to Holdings by Escrow Agent and the parties shall have no further rights or obligations
hereunder, except for those which expressly survive any such termination, or (b) waive its
objections hereunder and proceed with the transaction pursuant to the remaining terms and
conditions of this Agreement, without any reduction in the amount of the Holdings Capital
Contribution. Duke shall not be required to cure any matter objected to by Holdings. If Holdings
fails to so give Duke notice of its election within the timeframe required therefor, Holdings shall
be deemed to have elected the option contained in subpart (b) above. Holdings shall have the right
at any time to waive any objections that it may have made and, thereby, to preserve this Agreement
in full force and effect.

Notwithstanding anything to the contrary contained herein, Duke agrees to discharge by payment
prior to Closing, at Duke’s expense, any mortgages or loan documents that were voluntarily created
or assumed by Duke (excluding those related to the Loan), or undisputed liens for construction work
contracted for directly by Duke, which are recorded against the Property (“Duke’s Liens”). Duke,
at Duke’s expense, shall be obligated at Closing to discharge by payment or alternative manner
reasonably satisfactory to the Title Insurer and Holdings (including, without limitation, statutory
bonding and affirmative title coverage) liens recorded against the Property for construction work
not contracted for directly by Duke or disputed in good faith by Duke (“Non-Duke Liens”). In the
event Duke fails to release or cure Duke’s Liens or Non-Duke Liens, Holdings shall have the right
to terminate this Agreement and receive a return of the Earnest Money.

The foregoing procedures for making and responding to objections to title exceptions and
survey matters shall also apply with respect to any objections to title exceptions (other than
Permitted Title Exceptions) which first appear on updates of the Title Commitment received by
Holdings after the date of the Title Objection Notice (and Holdings shall provide Duke with copies
of any updated Title Commitments and Schedule B items first shown in such updated commitments) or
any survey matters that did not exist as of the date of the Title Objection Notice (other than
Permitted Title Exceptions), except that all such objections must be made on or before the
earlier of five (5) Business Days after Holdings becomes aware of such title exceptions or survey
matters or the Closing Date, and all agreements to cure and termination rights relating thereto
must be made or exercised, as applicable, on or before the earlier of the time periods provided in
the previous paragraph or the Closing Date.

5.2 Payment of Contractors. Subject to the terms of Section 5.1 hereof, all
contractors, subcontractors, suppliers, consultants, architects, engineers and others with whom
Duke has directly contracted (as opposed to such parties contracted by Tenant or a third-party) and
who have performed services or labor or have supplied materials in connection with Duke’s
acquisition, development, or construction of the Real Property, shall have been paid in full and
all liens arising therefrom shall have been bonded over or satisfied and released at or before
Closing, and to the extent such costs and expenses are not due and payable at Closing, Duke shall
promptly pay all such costs and expenses after Closing when due. This Section 5.2 shall survive
Closing.

Section 6. Holdings’ Inspection.

6.1 Document Inspection. Holdings and Duke acknowledge that Holdings shall
review and inspect the Duke Deliveries and any other documents provided or made available by Duke
or obtained by Holdings. Except as otherwise expressly provided herein, Duke makes no
representation or warranty as to the truth, accuracy or completeness of the Duke Deliveries or any
other studies, documents, reports or other information provided to Holdings by Duke.

6.2 Physical Inspection. Subject to the Lease, any restrictions of record
and applicable laws, Holdings and its agents shall have the right, from time to time prior to the
Inspection Date during normal business hours, to enter upon the Property to examine the same and
the condition thereof, and to conduct such surveys and to make such engineering and other
inspections, tests and studies as Holdings shall determine to be reasonably necessary, all at
Holdings’ sole cost and expense, including, without limitation, a Phase I environmental report and
a roof survey and report. Notwithstanding the foregoing, Holdings shall not conduct or allow any
physically intrusive testing of, on or under the Property. Holdings agrees to give Duke reasonable
advance verbal notice of such examinations or surveys and to conduct all examinations and surveys
of the Property in accordance with all applicable laws and in a manner that will not interfere with
the operations the Tenant thereon and will not harm or damage the Property or cause any claim
adverse to Duke or Tenant, and agrees to repair or restore the Property to its condition prior to
any such examinations or surveys immediately after conducting the same. Holdings shall not contact
Tenant concerning the Property without Duke’s prior consent, and Duke shall have the right to be
present during any such contacts. Holdings hereby indemnifies and holds Duke and any agent,
advisor, representative, affiliate, employee, director, partner, member, beneficiary, investor,
servant, shareholder, subsidiary, trustee or other person or entity acting on Duke’s behalf or
otherwise related to or affiliated with Duke (collectively, “Duke Related Parties”) harmless from
and against any claims, suits, losses, costs, expenses (including without limitation court costs
and attorneys’ fees), liabilities, judgments and damages (collectively, “Claims”), incurred by Duke
as a result of any inspection performed by Holdings, except for Claims against Duke based upon any
obligations and liabilities of Duke, which indemnity shall survive the Closing and any termination
of this Agreement. Prior to, and as a condition to any entry on the Property by Holdings or its
agents for the purposes set forth in this Section 6.2, Holdings shall deliver to Duke a
certificate of insurance evidencing comprehensive general liability coverage (including coverage
for contractual indemnities) with a combined single limit of at least $2,000,000.00 and excess
umbrella coverage for bodily injury and property damage in the amount of $5,000,000.00, in a form
reasonably acceptable to Duke, covering any activity, accident or damage arising in connection with
Holdings or agents of Holdings on the Property, and naming Duke, as an additional insured.
Holdings shall provide a copy of any written inspection, test, report or summary to Duke promptly
upon Holdings’ receipt thereof.

6.3 Formal Inspection Period. Holdings’ obligation to close under this
Agreement is subject to and conditioned upon Holdings’ investigation and study of and satisfaction
with the Property as set forth in this Section 6. Holdings shall have until 5:00 p.m.
E.S.T. on the Inspection Date in which to make such investigations and studies with respect to the
Property as Holdings deems appropriate and to terminate this Agreement, by written notice delivered
to Duke, if Holdings is not, for any reason, satisfied with the Property, in which case the Earnest
Money shall be returned to Holdings and neither party shall have any further obligations hereunder
except for those obligations of Holdings set forth in Sections 6.2 and 6.4. If
Holdings fails to deliver written notice to Duke of its election to terminate this Agreement on or
before 5:00 p.m. E.S.T. on the Inspection Date, then this Agreement shall be deemed to have been
terminated by Holdings, the Earnest Money shall be returned to Holdings and neither party shall
have any further obligations hereunder, except as expressly survive termination of this Agreement.

6.4 Confidentiality. Holdings and its representatives shall hold in
confidence all data and information relating to the Property, Duke or its business, whether
obtained before or after the execution and delivery of this Agreement pursuant to the
Confidentiality Agreement, which is incorporated herein and which Holdings hereby reaffirms. In
the event of a breach by Holdings or its representatives of this Section 6.4, Duke shall
be entitled to all remedies set forth in the Confidentiality Agreement. Nothing in this Agreement
shall be construed as prohibiting Duke from pursuing any other available remedy at law or in equity
for such breach of the Confidentiality Agreement. The provisions of this Section 6.4 shall
survive the Closing and any termination of this Agreement.

to authority validly and duly conferred upon Holdings and the signatories hereto. To Holdings’
knowledge, the consummation of the transaction herein contemplated and the compliance by Holdings
with the terms of this Agreement do not and will not conflict with or result in a breach of any of
the terms or provisions of, or constitute a default under, any agreement, arrangement,
understanding, accord, document or instrument by which Holdings is bound.

7.3 Miscellaneous.

7.3.1 As used herein, the phrase “Duke’s knowledge” or any derivation thereof shall
mean the actual knowledge of Jason Sturman, Vice President, Fund Management, provided, however, he
shall have no duty to investigate the matter to which such actual knowledge, or the absence
thereof, pertains. It shall be a condition of Closing that the representations and warranties
contained in this Section 7 are true and correct in all material respects on the Contract
Date and at Closing. In the event that Duke or Holdings learns that any of said representations or
warranties becomes inaccurate between the Contract Date and the Closing, Duke or Holdings, as
applicable, shall immediately notify the other party in writing of such change (a “Notice of
Inaccuracy”). If Duke does not cure such change by the Closing Date, Holdings may either (a)
terminate this Agreement by written notice to Duke, in which case the Earnest Money, together with
interest earned thereon, shall be returned to Holdings and the parties shall have no further rights
or obligations hereunder, except for those which expressly survive such termination, or (b) waive
such right to terminate by proceeding with the transaction pursuant to the remaining terms and
conditions of this Agreement without any reduction in the Agreed Value. In the event Holdings
elects option (b) in the preceding sentence, the representations and warranties shall be deemed to
be automatically amended to reflect said change.

7.3.2 Notwithstanding and without limiting the foregoing, (i) if any of the
representations or warranties of Duke that survive Closing contained in this Agreement or in any
document or instrument delivered in connection herewith are materially false or inaccurate, or Duke
is in material breach or default of any of its obligations under this Agreement that survive
Closing, and Holdings nonetheless closes the transactions hereunder and contributes the Holdings
Capital Contribution to the Company, then Duke shall have no liability or obligation respecting
such false or inaccurate representations or warranties or other breach or default (and any cause of
action resulting therefrom shall terminate upon the Closing) in the event that on or prior to
Closing, Holdings shall have had knowledge of the false or inaccurate representations or warranties
or other breach or default.

7.4 Reaffirmation. Subject to the provisions of Section 7.3.1, at
Closing, Duke shall be deemed to have reaffirmed that representations and warranties of Duke in
this Section 7 are true and correct in all material respects. At Closing, Holdings shall
be deemed to have reaffirmed that the representations and warranties of Holdings in this
Section 7 are true and correct.

7.5 Construction Defect Warranty. Notwithstanding anything to the contrary
contained herein, Duke shall make any repairs and replacements necessary to correct any defect in
workmanship or material in the Building for the period from Closing until June 30, 2008, provided
Holdings notifies Duke in writing of such defect on or before June 30, 2008. Duke shall have the
benefit of any subcontractor warranties in connection with the performance of Duke’s obligations
under the preceding sentence. In the event Duke fails to make such repairs and replacements
promptly, and such failure continues for thirty (30) days after written notice thereof from
Holdings to Duke (or if such repair or replacement cannot reasonably be completed in thirty days
then if Duke fails to commence such repair and/or replacement and diligently pursue completion
thereof), then the Company may complete such repair or replacement and Duke shall reimburse the
Company for all reasonable out-of-pocket costs incurred by the Company upon written demand
therefor. Duke’s obligation under this Section are herein collectively called the “Construction
Warranty”. This Section shall survive Closing.

Section 8. Operations Pending Closing. Duke hereby covenants from and after
the Contract Date as follows:

8.1 Duke, at its expense, shall use commercially reasonable efforts to (i) operate
the Property from and after the Contract Date in substantially the same manner as prior thereto and
(ii) cause the Tenant to, maintain the Property until the Closing or sooner termination of this
Agreement, substantially in its present condition and pursuant to Tenant’s normal course of
business and as required by the Lease, subject to ordinary wear and tear, damage by fire or other
casualty and condemnation. Duke shall also perform all normal maintenance from and after the
Contract Date in the same fashion as prior to the Contract Date.

8.2 To provide Holdings with copies of (a) any default letters sent to or received
from Tenant and, (b) any copies of correspondence received from Tenant that it is discontinuing
operations at the Real Property or seeking to re-negotiate the Lease and (c) notices of bankruptcy
filings received with respect to Tenant.

8.3 After the Contract Date, without Holdings’ consent, not to be unreasonably
withheld, conditioned or delayed, Duke shall not enter into any contract for service to the
Property unless it is terminable without penalty on no more than thirty (30) days written notice
(except that Duke may enter into any such contract in response to any condition or event which
would endanger the safety or integrity of the Improvements, provided that the Company shall have no
obligation to assume any such contract unless Holdings approves of such contract in writing). Duke
shall promptly deliver a copy of any item in the preceding sentence entered into by Duke
following the Inspection Date.

8.4 To cause to be in force fire and extended coverage insurance upon the Real
Property, and public liability insurance with respect to damage or injury to persons or property
occurring on the Real Property in at least such amounts, and with the same deductibles, as are
maintained by Duke on the date hereof.

8.5 To not enter into any new lease with respect to the Real Property, without
Holdings’ prior written consent; provided, however Tenant’s right under the Lease to enter into
subleases and licenses without landlord’s consent shall not be subject to this Section 8.5.
Exercise of a mandatory renewal option shall not be considered a new lease. To the extent
specifically disclosed to and approved by Holdings in connection with any request for approval, any
brokerage commission and the cost of tenant improvements or other allowances payable with respect
to a new lease shall be prorated between Company and Duke in accordance with their respective
periods of ownership as it bears to the primary term of the new lease. Further, except for the
Commencement Agreement, which shall not require Holdings’ approval, Duke will not modify or cancel
the Lease without first obtaining the written consent of Holdings. Holdings shall have five (5)
Business Days following receipt of a request for any consent pursuant to this Section in which to
approve or disapprove of any new lease or any modification or cancellation of the Lease (other than
the Commencement Agreement). Failure to respond in writing within said time period shall be deemed
to be approval. Duke’s execution of a new lease or modification or cancellation of the Lease
following Holdings’ reasonable refusal to consent thereto shall constitute a default hereunder.
Holdings shall have sole discretion in all such matters contained in this Section 8.5.

8.6 To not sell, assign, or convey any right, title, or interest whatsoever in or to
the Real Property, or create any security interest, easement, encumbrance, charge, or condition
affecting the Real Property (other than the Permitted Exceptions).

8.7 To use commercially reasonable efforts to obtain the SNDA and Estoppel
Certificate from the Tenant.

Section 9. Conditions to Closing.

obligations under the Lease that such assertion is made “to Tenant’s knowledge” or
similar qualification made by Tenant shall be acceptable and (ii) the SNDA shall be
acceptable if the lender requiring the SNDA has approved it. If Holdings disapproves
of the Tenant Estoppel Certificate or SNDA, and Duke is unable to deliver, in Holdings’
good faith business judgment, a reasonably acceptable estoppel certificate or SNDA (as
the case may be) prior to the Closing Date, Holdings shall have the right to terminate
this Agreement and to obtain a refund of the Earnest Money without any further action
required by any party, and neither party shall have any further obligation to the
other, except for those matters that expressly survive termination of this Agreement.

	 	(d)	 	The terms and conditions of the Loan and the documents to be executed in
connection with the Loan (the “Loan Documents”) have been approved by Holdings. Fully
executed Loan Documents and the Loan proceeds shall have been received by the Company.

	 	(e)	 	On the Closing Date, the Title Insurer shall be unconditionally obligated and
prepared, subject to the payment of the applicable title insurance premium and other
related charges, to issue to Company the Title Policy.

any Bankruptcy Law) a voluntary case, nor shall there have been commenced against Duke
an involuntary case, nor shall Duke have consented to the appointment of a Custodian of
it or for all or any substantial part of its property, nor shall a court of competent
jurisdiction have entered an order or decree under any Bankruptcy Law that is for
relief against Duke in an involuntary case or appoints a Custodian of Duke for all or
any substantial part of its property. The term “Bankruptcy Law” means Title 11, U.S.
Code, or any similar state law for the relief of debtors. The term “Custodian” means
any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

In the event any of the foregoing conditions are not satisfied prior to or at the
Closing, Holdings may terminate this Agreement by written notice to Duke and thereafter
shall have no obligation to proceed with Closing. If Holdings so terminates this Agreement,
neither party shall have any further obligation hereunder except those which expressly
survive the termination of this Agreement. Notwithstanding the foregoing but subject to
Sections 11.2 and 11.3 hereinbelow, nothing contained in this Section
9.1 shall waive or diminish any right or remedy Holdings may have for Duke’s default or
breach of this Agreement.

9.2 Duke’s Conditions Precedent. Duke’s obligation to proceed to Closing
under this Agreement is subject to the following conditions precedent:

	 	(a)	 	Duke receiving all corporate and partnership approvals to complete this
transaction on or before the Inspection Date. In the event this condition is not
satisfied on or prior to the Inspection Date, Duke may deliver written notice thereof
to Holdings on or before the Inspection Date whereupon this Agreement shall cease and
terminate, the Earnest Money shall be returned and paid to Holdings, and neither party
shall have any further obligation hereunder except those which expressly survive the
termination of this Agreement. If Duke fails to so notify Holdings on or before the
Inspection Date, this condition shall be deemed waived.

	 	(b)	 	Holdings shall have materially performed and satisfied each and all of
Holdings’ material obligations under this Agreement and Holdings’ representations and
warranties hereunder shall be true and correct in all material respects. In the event
this condition is not satisfied on or prior to the Closing Date, Duke shall have no
obligation to proceed to Closing and, if Duke delivers written notice to Holdings that
the foregoing condition has not been satisfied, this Agreement shall cease and
terminate, the Earnest Money shall be returned and paid to Holdings, and neither party
shall have any further obligation hereunder except those which expressly survive the
termination of this Agreement.

	 	(c)	 	The terms and conditions of the Loan and the Loan Documents have been approved
by Duke. Fully executed Loan Documents and the Loan proceeds shall have been received
by the Company.

Notwithstanding the foregoing, nothing contained in this Section 9.2 shall
waive or diminish any right or remedy Duke may have for Holdings’ default or breach of this
Agreement.

Agreement are theretofore fully satisfied, waived or performed, the Closing shall be held in escrow

consummate the Closing.

Section 11. Default and Remedies.

11.1 Holdings’ Default. In the event of a default by Holdings under the
terms of this Agreement, which is not cured by Holdings as provided hereunder within seven (7) days
after written notice by Duke, and due to such event of default by Holdings, the Closing does not
occur, Duke’s sole and exclusive remedy hereunder shall be to terminate this Agreement. If Duke
terminates this Agreement as provided in the previous sentence and after a cure period of seven (7)
days, the Escrow Agent shall disburse the Earnest Money to Duke, and Duke shall be entitled to
retain the Earnest Money for such default of Holdings, whereupon this Agreement shall terminate and
the parties shall have no further rights or obligations hereunder, except for those which expressly
survive any such termination. Notwithstanding the foregoing, nothing contained herein shall waive
or diminish any right or remedy Duke may have at law or in equity for Holdings’ default or breach
of Section 6.2 or Section 6.4 of this Agreement. It is hereby agreed that Duke’s
damages in the event of a default by Holdings hereunder are uncertain and difficult to ascertain,
and that the Earnest Money constitutes a reasonable liquidation of such damages and is intended not
as a penalty, but as liquidated damages. This provision shall expressly survive the termination of
this Agreement.

11.2 Duke’s Default. Subject to Section 7.3, in the event of a
default by Duke under the terms of this Agreement which is not cured by Duke as provided hereunder
within seven (7) days after written notice by Holdings and due to such event of default by Duke the
Closing does not occur, Holdings’ sole and exclusive remedies hereunder shall be to either (a)
terminate this Agreement, whereupon Holdings will receive a refund of the Earnest Money from Escrow
Agent and neither party hereto shall have any further obligation or liability to the other (except
with respect to those provisions of this Agreement which expressly survive the termination hereof),
Holdings hereby waiving any right or claim to damages for Duke’s breach, or (b) provided the
Holdings Capital Contribution has been deposited with Escrow Agent on or before the scheduled
Closing Date, seek specific performance of Duke’s obligations under this Agreement (but no other
action, for damages or otherwise, shall be permitted); provided that any action by Holdings for
specific performance must be filed, if at all, within thirty (30) days of Duke’s default, and the
failure to file within such period shall constitute a waiver by Holdings of such right and remedy.
If Holdings shall not have filed an action for specific performance within the aforementioned time
period or so notified Duke of its election to terminate this Agreement, Holdings’ sole remedy shall
be to terminate this Agreement in accordance with clause (a) above. Notwithstanding the foregoing,
if Duke’s default constitutes an Intentional Duke Default (as hereinafter defined) and Holdings
makes the election described in clause (a) above, then Holdings shall also have the right to
receive reimbursement for its out-of-pocket costs in an amount equal to the lesser of (i) One
Hundred Fifty Thousand Dollars ($150,000.00) in the aggregate, or (ii) the amount of all
third-party out-of-pocket costs and expenses actually incurred by Holdings in connection with this
Agreement and the Property (“Third-Party Costs”), including due diligence costs, engineering and
environmental review costs, and legal fees and expenses. In no event shall Duke be liable for
consequential, speculative, remote or punitive damages, or any damages other than Third-Party
Costs, and Holdings hereby waives any right to seek or collect any such consequential, speculative,
remote or punitive damages, or any damages other than Third-Party Costs (such Third Party Costs to
be limited in all cases as provided above). “Intentional Duke Default” means any one or more of
the following: (x) fraudulent misrepresentation, (y) criminal conduct (i.e. conduct that
constitutes a felony under applicable law), or (z) an intentional and deliberate act of Duke taken
on or after the Contract Date that is intended to result in, and does result in, Duke’s failure to
perform in accordance with this Agreement.

11.3 Limitation on Liability.

11.3.1 Notwithstanding anything to the contrary contained in this Agreement or any
document executed in connection herewith, the aggregate liability of Duke arising pursuant to or in
connection with the representations, warranties, indemnifications, covenants or other obligations
(whether express or implied) of Duke under this Agreement (or any document or certificate executed
or delivered in connection herewith), shall not exceed $900,000.00, however, Holdings shall not
make any claims in connection with the representations, warranties, indemnifications, covenants or
other obligations (whether express or implied) of Duke under this Agreement unless such claims in
the aggregate exceed $50,000.00. This limits in this Section 11.3 shall not apply to the
Construction Warranty.

11.3.2 No shareholder or agent of Duke, nor any Duke Related Parties, shall have any
personal liability, directly or indirectly, under or in connection with this Agreement or any
agreement made or entered into under or pursuant to the provisions of this Agreement, or any
amendment or amendments to any of the foregoing made at any time or times, heretofore or hereafter,
and Holdings and its successors and assigns and, without limitation, all other persons and
entities, shall look solely to Duke’s assets for the payment of any claim or for any performance,
and Holdings, on behalf of itself and its successors and assigns, hereby waives any and all such
personal liability.

11.3.3 The provisions of this Section 11.3 shall survive the Closing or
sooner termination of this Agreement.

Section 12. Condemnation or Destruction.

12.1 Condemnation. If, prior to the Closing, the Property is subject to a
bona fide written threat of Material Condemnation (as hereinafter defined) by a body having the
power of eminent domain, or is taken by eminent domain or condemnation, or sale in lieu thereof,
then Duke, within three (3) business days after Duke receives notice of such occurrence, shall give
Holdings written notice of such occurrence and the nature and extent of such Material Condemnation.
Within thirty (30) days after written notification to Holdings of the estimated amount of the
condemnation award resulting from a Material Condemnation, as determined by a third party
independent contractor, engineer or appraiser selected by Duke, subject to Holdings’ reasonable
approval (the “Appraiser”), Holdings shall have the right, by giving written notice to Duke, to
terminate this Agreement, in which event this Agreement shall automatically terminate, the Earnest
Money shall be returned to Holdings without any further action required from either party, Holdings
and Duke shall each be liable for one-half of any escrow fees or charges and neither party shall
have any continuing obligations hereunder. If, before the Closing, proceedings are commenced for
the taking by exercise of the power of eminent domain of less than a Material Condemnation, or if
Holdings has the right to terminate this Agreement pursuant to the preceding sentence but Holdings
does not exercise such right, then this Agreement shall remain in full force and effect and, on the
Closing Date, the condemnation award (or, if not theretofore received, the right to receive such
portion of the award) payable on account of the taking shall be assigned, or paid to, Company. The
foregoing notwithstanding, in the event the taking results in the cancellation of, or rent
abatement under, the Lease, Holdings shall have the option to terminate this Agreement. For
purposes hereof, a “Material Condemnation” shall be one which results or would result in damage or
loss affecting the Property in an amount greater than five percent (5%) of the Agreed Value, as
determined by the Appraiser

12.2 Damage or Destruction. If, prior to the Closing, a Material Casualty
(as hereafter defined) shall affect the Property, Duke agrees to give Holdings written notice of
such occurrence and the nature and extent of such damage and destruction. Within thirty (30)
days after written notification to Holdings of the estimated amount of the damages to the Property
resulting from a Material Casualty, as determined by the Appraiser, then Triple may in its
discretion either (i) elect to terminate this Agreement, in which case the Earnest Money shall be
returned to Holdings without any further action required from either party, Holdings and Duke shall
each be liable for one-half of any escrow fees or charges and neither party shall have any further
obligation to the other or (ii) proceed to Closing in which event any insurance proceeds, plus the
cash amount of any associated deductible, shall be paid over to Company. In the event that the
casualty is uninsured, Holdings may terminate this Agreement unless Holdings receives a credit
against the Holdings Capital Contribution equal to the cost of repairs. The foregoing
notwithstanding, in the event any casualty results in the cancellation of, or rental abatement
under the Lease, Holdings shall have the option to terminate this Agreement without regard to the
cost of repairs. For purposes hereof, a “Material Casualty” shall be a casualty, which results or
would result in damage or loss affecting the Property in an amount greater than five percent (5%)
of the Agreed Value, as determined by the Appraiser.

Section 13. Assignment. Duke shall not assign any of its right, title or
interest in and to this Agreement. Holdings may not assign its rights under this Agreement without
Duke’s written consent, which consent may be granted or withheld in Duke’s sole and absolute
discretion; provided, however, that Holdings may, upon five (5) days prior written notice to Duke,
assign this Agreement to Grubb & Ellis Healthcare REIT, Inc. or its affiliate; provided, however,
(x) Holdings’ assignee shall assume in writing all of Holdings’ obligations hereunder pursuant to
an assignment and assumption agreement in form and content acceptable to Duke in the exercise of
Duke’s reasonable judgment and (z) no assignment of this Agreement shall relieve Holdings of its
obligations hereunder.

Section 14. Intentionally Omitted.

Section 15. Brokers and Brokers’ Commissions. Holdings and Duke each
warrant and represent to the other that neither party has employed a real estate broker or agent in
connection with the transaction contemplated hereby, except SavillsGranite, which shall be paid by
Duke pursuant to the terms of a separate agreement. Each party agrees to indemnify and hold the
other harmless from any loss or cost suffered or incurred by it as a result of the other’s
representation herein being untrue. This Section 15 shall expressly survive the Closing
hereunder.

Section 16. Notices.

Wherever any notice or other communication is required or permitted hereunder, such notice or
other communication shall be in writing and shall be delivered by hand, by nationally-recognized
overnight express delivery service, by U.S. registered or certified mail, return receipt requested,

Section 17. Disclaimer of Condition.

17.1 Disclaimer; Release. Subject to the express representations of Duke in
Section 7.1 and the covenants of Duke in this Agreement to the extent such covenants
survive Closing, the Construction Warranty and the documents delivered at Closing (collectively,
"Duke’s Warranties”), it is understood and agreed that Duke is not making and has not at any time
made any warranties or representations of any kind or character, expressed or implied, with respect
to the Property, including, but not limited to, any warranties or representations as to
habitability, merchantability, fitness for a particular purpose, title (other than Duke’s limited
warranty of title to be set forth in the Deed), zoning, tax consequences, latent or patent physical
or environmental condition, utilities, operating history or projections, valuation, governmental
approvals, the compliance of the Property with governmental laws, the truth, accuracy or
completeness of the Property documents or any other information provided by or on behalf of Duke to
Holdings or the Company, or any other matter or thing regarding the Property. Subject to the
express representations of Duke in the Duke’s Warranties, Holdings acknowledges and agrees that
upon Closing, Duke shall sell and convey to the Company and Company shall accept the Property “AS
IS, WHERE IS, WITH ALL FAULTS,” except to the extent otherwise expressly provided in this
Agreement. Subject to the express representations of Duke in the Duke’s Warranties, Holdings has
not relied and will not rely on, and Duke is not liable for or bound by, any expressed or implied
warranties, guaranties, statements, representations or information pertaining to the Property or
relating thereto (including specifically, without limitation, Property information packages
distributed with respect to the Property) made or furnished by Duke, the manager of the Property,
or any real estate broker or agent representing or purporting to represent Duke, to whomever made
or given, directly or indirectly, orally or in writing. Holdings represents to Duke that Holdings
has conducted, or will conduct prior to Closing, such investigations of the Property, including but
not limited to, the physical and environmental conditions thereof, as Holdings deems necessary to
satisfy itself as to the condition of the Property and the existence or nonexistence or curative
action to be taken with respect to any hazardous or toxic substances on or discharged from the
Property, and will rely solely upon same and not upon any information provided by or on behalf of
Duke or its agents or employees with respect thereto, other than such representations, warranties
and covenants of Duke as are expressly set forth in this Agreement. Subject to the express
representations and covenants of Duke in the Duke’s Warranties, upon Closing, the Company shall
assume the risk that adverse matters, including but not limited to, construction defects and
adverse physical and environmental conditions, may not have been revealed by Holdings’
investigations, and Holdings and the Company, upon Closing, shall be deemed to have waived,
relinquished and released Duke and Duke Related Parties from and against any and all claims,
demands, causes of action (including, without limitation, causes of action in tort), losses,
damages, liabilities, costs and expenses (including, without limitation, attorneys’ fees and court
costs) of any and every kind or character, known or unknown, which the Company, Holdings or any
agent, representative, affiliate, employee, director, officer, partner, member, servant,
shareholder or other person or entity acting on the Company’s or Holdings’ behalf or otherwise
related to or affiliated with Holdings might have asserted or alleged against Duke and/or Duke
Related Parties at any time by reason of or arising out of any latent or patent construction
defects, physical conditions (including, without limitation, environmental conditions), the Lease
and the Tenant, violations of any applicable laws (including, without limitation, any environmental
laws) or any and all other acts, omissions, events, circumstances or matters regarding the
Property. Neither Holdings nor the Company shall look to Duke or any Duke Related Parties in
connection with the foregoing for any redress or relief. The foregoing release shall be given full
force and effect according to each of its expressed terms and provisions, including those relating
to unknown and unsuspected claims, damages and causes of action.

17.2 Effect and Survival of Disclaimer and Release. Duke and Holdings
acknowledge that the Agreed Value reflects that the Property is being contributed subject to the
provisions of this Section 17, and Duke and Holdings agree that the provisions of this
Section 17 shall survive Closing indefinitely.

Section 18. Miscellaneous.

18.1 Governing Law; Headings; Rules of Construction. This Agreement shall
be governed by and construed in accordance with the internal laws of the State in which the Land is
located, without reference to the conflicts of laws or choice of law provisions thereof. The
titles of sections and subsections herein have been inserted as a matter of convenience of
reference only and shall not control or affect the meaning or construction of any of the terms or
provisions herein. All references herein to the singular shall include the plural, and vice versa.
The parties agree that this Agreement is the result of negotiation by the parties, each of whom
was represented by counsel, and thus, this Agreement shall not be construed against the maker
thereof.

18.2 No Waiver. Neither the failure of either party to exercise any power
given such party hereunder or to insist upon strict compliance by the other party with its
obligations hereunder, nor any custom or practice of the parties at variance with the terms hereof
shall constitute a waiver of either party’s right to demand exact compliance with the terms hereof.

18.3 Entire Agreement. Except for the Confidentiality Agreement and the
Operating Agreement, this Agreement contains the entire agreement of the parties hereto with
respect to the Property and any other prior understandings or agreements are merged herein and no
representations, inducements, promises or agreements, oral or otherwise, between the parties not
embodied herein or incorporated herein by reference shall be of any force or effect.

18.4 Binding Effect. This Agreement shall be binding upon and shall inure
to the benefit of the parties hereto and their respective heirs, executors, administrators, legal
representatives, successors and assigns (subject to Section 13 above).

18.5 Amendments. No amendment to this Agreement shall be binding on any of
the parties hereto unless such amendment is in writing and is executed by the party against whom
enforcement of such amendment is sought.

18.6 Date For Performance. If the time period by which any right, option or
election provided under this Agreement must be exercised, or by which any act required hereunder
must be performed, or by which the Closing must be held, expires on a Saturday, Sunday or legal or
bank holiday, then such time period shall be automatically extended through the close of business
on the next regularly scheduled Business Day.

18.7 Recording. Duke and Holdings agree that they will not record this
Agreement and that they will not record a short form of this Agreement.

18.8 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which, when taken
together, shall constitute but one and the same instrument.

18.9 Time of the Essence. Time shall be of the essence of this Agreement
and each and every term and condition hereof.

18.10 Severability. This Agreement is intended to be performed in
accordance with, and only to the extent permitted by, all applicable laws, ordinances, rules and
regulations. If any term or provision of this Agreement or the application thereof to any person
or circumstance shall for any reason and to any extent be held to be invalid or unenforceable, then
such term or provision shall be ignored, and to the maximum extent possible, this Agreement shall
continue in full force and effect, but without giving effect to such term or provision.

18.11 Attorneys’ Fees. In the event that either party shall bring an action
or legal proceeding for an alleged breach of any provision of this Agreement or any representation,
warranty, covenant or agreement herein set forth, or to enforce, protect, determine or establish
any term, covenant or provision of this Agreement or the rights hereunder of either party, the
prevailing party shall be entitled to recover from the non-prevailing party, as a part of such
action or proceedings, or in a separate action brought for that purpose, reasonable attorneys’ fees
and costs, expert witness fees and court costs as may be fixed by the court or jury.

18.12 Publicity. Between the Contract Date and the Closing, Duke and
Holdings shall discuss and coordinate with respect to any public filing or announcement concerning
the contributions as contemplated hereunder. Nothing in the forgoing sentence shall limit
Holdings’ obligations pursuant to Section 6.4 hereof.

18.13 Discharge of Duke’s Obligations. Except as otherwise expressly
provided in this Agreement, Holdings’ acceptance of the Deed shall be deemed a discharge of all of
the obligations of Duke hereunder and all of Duke’s representations, warranties, covenants and
agreements in this Agreement shall merge in the documents and agreements executed at the Closing
and shall not survive the Closing, except and to the extent that, pursuant to the express
provisions of this Agreement, any of such representations, warranties, covenants or agreements are
to survive the Closing.

18.14 Disclosure. Notwithstanding any terms or conditions in this Agreement
to the contrary, but subject to restrictions reasonably necessary to comply with federal or state
securities laws, any person may disclose to any and all persons, without limitation of any kind,
the tax treatment and tax structure of the transaction and all materials of any kind (including
opinions or other tax analyses) that are provided relating to such tax treatment and tax structure.
For the avoidance of doubt, this authorization is not intended to permit disclosure of the names
of, or other identifying information regarding, the participants in the transaction, or of any
information or the portion of any materials not relevant to the tax treatment or tax structure of
the transaction. The provisions of this Section 18.14 shall survive the Closing.

18.15 Waiver of Trial by Jury. Duke and Holdings hereby irrevocably and
unconditionally waive any and all right to trial by jury in any action, suit or counterclaim
arising in connection with, out of or otherwise relating to, this Agreement. The provisions of
this Section 18.15 shall survive the Closing or termination hereof.

18.16 Information and Audit Cooperation. At Holdings’ request, at any time
after Closing and continuing for a period of one (1) year after Closing, Duke shall provide to
Holdings’ designated independent auditor access to the books and records of the Property, and all
related information regarding the Property for the period for which Holdings is required to have
the Property audited, and Duke shall provide to such auditor a representation letter regarding the
books and records of the Property, in substantially the form of Exhibit I attached hereto,
in connection with the normal course of auditing the Property in accordance with generally accepted
auditing standards.
