(b) Assuming Borrower shall not hereafter, without Lender’s prior consent in accordance with

this Agreement applicable to the “Borrower” or “Assignor” in accordance with their respective terms
and conditions including, but not limited to, the representations, warranties, covenants,
assurances and indemnifications therein, all as though each of the Loan Documents had been made,
executed and delivered by Assuming Borrower. Assuming Borrower agrees to pay when and as due all
sums due under the Note and agrees to pay, perform and discharge each and every other obligation of
payment and performance of the “Borrower” or “Assignor” pursuant to and as set forth in the Loan
Documents at the time, in the manner and otherwise in all respects as therein provided. Assuming
Borrower hereby acknowledges, agrees and warrants that to its knowledge: (i) there are no rights of
set-off or counterclaim, nor any defenses of any kind, whether legal, equitable or otherwise, which
would enable Assuming Borrower to avoid or delay timely performance of its obligations under the
Loan Documents, as applicable; and (ii) there are no monetary encumbrances or liens of any kind or
nature against the Property except those created by the Loan Documents, and all rights, priorities,
titles, liens and equities securing the payment of the Note are expressly recognized as valid and

4. Assumption of the Obligations of the Indemnitor under the Indemnity Agreement and
Environmental Indemnity Agreement; Substitution of Indemnitor. From and after the date of this
Agreement, Assuming Indemnitor shall be obligated and responsible for the performance of each and
all of the obligations and agreements of the “Indemnitor,” “Guarantor” or “Principal” (collectively
referred to herein as “Indemnitor”) under the Indemnity Agreement, the Environmental Indemnity
Agreement and the other Loan Documents to which Original Indemnitor is a party. Assuming Indemnitor
shall be liable and responsible for each and all of the liabilities of the Indemnitor thereunder,
and shall be substituted in lieu of and in place of Original Indemnitor as fully and completely as
if Assuming Indemnitor had originally executed and delivered such Loan Documents as the Indemnitor
thereunder including, without limitation, all of those obligations, agreements and liabilities
which would have, but for the provisions of this Agreement, been the obligations, agreements and
liabilities of Original Indemnitor, without regard to when such obligations, agreements and
liabilities arise, accrue or have arisen or accrued, and without regard to the Indemnitor then
responsible or liable therefor at the time of such accrual. From and after the date hereof,
Assuming Indemnitor further agrees to abide by and be bound by all of the terms of the Loan
Documents having reference to the Indemnitor, all as though each of the Loan Documents to which
Original Indemnitor is a party had been made, executed and delivered by Assuming Indemnitor as the
Indemnitor. From and after the date hereof, Assuming Indemnitor hereby agrees to pay, perform and
discharge each and every obligation of payment and performance of the Indemnitor under, pursuant to
and as set forth in the Loan Documents at the time, in the manner and otherwise in all respects as
therein provided. With respect to the Environmental Indemnity Agreement, the liability of Assuming
Indemnitor shall be joint and several with that of Assuming Borrower.

5. Notices to Indemnitor. Without amending, modifying or otherwise affecting the
provisions of the Loan Documents except as expressly set forth herein, Lender shall, from and after
the date of this Agreement, deliver any notices to the Indemnitor which are required to be
delivered pursuant to the Loan Documents or are otherwise delivered by Lender thereunder at
Lender’s sole discretion, to Assuming Indemnitor’s address set forth above.

6. Consent to Conveyance; Assumption and Substitution of Indemnitor; Release of Original
Obligors; Lender Estoppel. Subject to the terms and conditions set forth in this Agreement,
Lender consents to: (a) the sale, conveyance, assignment and transfer of the Property by Original
Borrower to Assuming Borrower, subject to the Mortgage and the other Loan Documents; (b) the
assumption by Assuming Borrower of the Loan and the obligations of Original Borrower under the Loan
Documents as modified by this Agreement; and (c) the assumption by Assuming Indemnitor of the
obligations of Original Indemnitor under the Loan Documents as modified by this Agreement. Original
Obligors are hereby released from any liability to Lender under any and all of the Loan Documents
first arising or accruing subsequent to the Assumption. Lender’s consent to such transfer and
Assumption shall, however, not constitute its consent to any subsequent transfers of the Property.
Original Obligors hereby acknowledge and agree that the foregoing release shall not be construed to
release Original Obligors from any personal liability under the Note or any of the other Loan
Documents for any act or event occurring or obligation arising prior to or simultaneously with the
closing of the transaction described herein.

Lender hereby represents and warrants to Assuming Obligors and Original Obligors that, to the
“actual knowledge of Lender”: (i) as of the date hereof, no default or Event of Default under the
Loan Documents has occurred and is continuing, and (ii) no facts or circumstances exist which
through the passage of time, would constitute an Event of Default. For purposes of this paragraph,
the “actual knowledge of Lender” shall mean the actual knowledge of employees of Wachovia Bank
National Association (“Wachovia”) actively involved with the transactions described herein or with
the servicing of the Loan without any independent inquiry or investigation. The “actual knowledge
of Lender” shall not include knowledge imputed from other Lender Parties or other groups or
employees of Wachovia not actively involved in the servicing of the Loan. Lender reserves the
right to declare any existing default or Event of Default which is not currently known but which
subsequently comes to the attention of Lender.

7. Release and Covenant Not to Sue. Original Borrower and Assuming Obligors, on behalf
of themselves and their heirs, successors and assigns, hereby release and forever discharge Lender,
any trustee of the Loan, any servicer of the Loan, each of their respective predecessors in
interest and successors and assigns, together with the officers, directors, partners, employees,
investors, certificate holders and agents of each of the foregoing (collectively, “Lender
Parties”), from all debts, accountings, bonds, warranties, representations, covenants, promises,
contracts, controversies, agreements, claims, damages, judgments, executions, actions, inactions,
liabilities, demands or causes of action of any nature, at law or in equity, known or unknown
(collectively, “Actions”), which Original Obligors and Assuming Obligors now have by reason of any
cause, matter or thing through and including the date hereof including, without limitation, matters
arising out of or relating to: (a) the Loan including, without limitation, its funding,
administration and servicing; (b) the Loan Documents; (c) the Property; (d) any reserve and escrow
balances held by Lender or any servicers of the Loan; or (e) the sale, conveyance, assignment and
transfer of the Property. Original Obligors and Assuming Obligors, on behalf of themselves and
their heirs, successors and assigns, covenant and agree never to institute or cause to be
instituted or continue prosecution of any suit or other form of action or proceeding of any kind or
nature whatsoever against any of Lender Parties by reason of or in connection with any of the
foregoing matters, claims or causes of action. Notwithstanding anything to the contrary herein,
this Section 7 shall only apply to the Assuming Obligors with respect to (and accordingly, the
release and discharge of Lender Parties by Assuming Obligors shall only be effective with respect
to) Actions which arose prior to the date hereof, and Assuming Obligors shall retain all rights and
remedies against the Lender Parties with respect to any Actions arising from and after the date
hereof.

8. Acknowledgment of Indebtedness. This Agreement recognizes the reduction of the
principal amount of the Note and the payment of interest thereon to the extent of payments made by
Original Borrower prior to the date of execution of this Agreement. The parties acknowledge and
agree that: (i) as of the date of this Agreement, the principal balance of the Note is
$5,733,945.09 and interest on the Note is paid to August 1, 2007 and (ii) Lender is holding the
following escrow and reserve balances:

	Northside Rollover Fund Reserve:
	 	$	56,540.71	 

Assuming Borrower acknowledges and agrees that the Loan, as evidenced and secured by the Loan
Documents, is a valid and existing indebtedness payable by Assuming Borrower to Lender. The
parties acknowledge and agree that Lender shall continue to hold the escrow and reserve balances
for the benefit of Assuming Borrower in accordance with the terms of the Loan Documents. Original
Borrower covenant and agree that Lender Parties have no further duty or obligation of any nature to
Original Borrower relating to such escrow and reserve balances. Original Borrower hereby release
and forever discharge Lender Parties from any obligations to Original Borrower relating to such
escrow and reserve balances. Assuming Obligors acknowledge and agree that the funds listed above
constitute all of the reserve and escrow funds currently held by Lender with respect to the Loan
and authorize such funds to be transferred to an account controlled by Lender for the benefit of
Lender and Assuming Borrower.

(b) Failure to Comply. Any failure of Assuming Obligors or Original Borrower to

or approval of any subsequent sale, conveyance, assignment or transfer of the Property, and that
Section 8 of the Mortgage shall continue in full force and effect.

14. Additional Representations, Warranties and Covenants of Assuming Obligors. As a
condition of this Agreement, Assuming Obligors represent and warrant to Lender as follows:

(a) Assuming Borrower is a limited liability company duly organized, validly existing and in
good standing under the laws of the State of Delaware and is qualified to transact business and in
good standing in the State of Georgia. Assuming Borrower has full power and authority to enter into
and carry out the terms of this Agreement and to assume and carry out the terms of the Loan

(c) This Agreement and the Loan Documents constitute legal, valid and binding obligations of
Assuming Obligors enforceable in accordance with their respective terms. Neither the entry into nor
the assumption and performance of and compliance with this Agreement or any of the Loan Documents
has resulted or will result in any violation of, or a conflict with or a default under, any
judgment, decree, order, mortgage, indenture, contract, agreement or lease by which Assuming
Obligors or any property of Assuming Obligors are bound or any statute, rule or regulation
applicable to Assuming Obligors.

(d) There is no action, proceeding or investigation pending or, to Assuming obligors’
knowledge, threatened which questions, directly or indirectly, the validity or enforceability of
this Agreement or any of the other Loan Documents, or any action taken or to be taken pursuant
hereto or thereto, or which might result in any material adverse change in the condition (financial
or otherwise) or business of Assuming Obligors.

(e) To Assuming obligors’ knowledge, there has been no legislative action, regulatory change,
revocation of license or right to transact business, fire, explosion, flood, drought, windstorm,
earthquake, accident, other casualty or act of God, labor trouble, riot, civil commotion,
condemnation or other action or event which has had any material adverse effect on the business or
condition (financial or otherwise) of Assuming Obligors or any of their properties or assets,
whether insured against or not, since Assuming Obligors submitted to Lender their request to assume
the Loan.

(f) The financial statements and other data and information supplied by Assuming Obligors in
connection with Assuming Obligors’ request to assume the Loan or otherwise supplied in
contemplation of the assumption of the Loan by Assuming Obligors were in all material respects true
and correct on the dates they were supplied, and since their dates no material adverse change in
the financial condition of Assuming Obligors has occurred, and there is not any pending or, , to
Assuming obligors’ knowledge, threatened litigation or proceedings which might impair to a material
extent the business or financial condition of Assuming Obligors.

(g) Without limiting the generality of the assumption of the Loan Documents by Assuming
Obligors, Assuming Obligors hereby specifically remake and reaffirm the representations, warranties
and covenants set forth in the Loan Documents as modified by this Agreement, to which they are a
party.

(h) No representation or warranty of Assuming Obligors made in this Agreement contains any
untrue statement of material fact or omits to state a material fact necessary in order to make such
representations and warranties not misleading in light of the circumstances under which they are
made.

(i) Assuming Borrower hereby represents and warrants to Lender that Assuming Borrower will not
permit the transfer of any interest in Assuming Borrower to any person or entity (or any beneficial
owner of such entity) who is listed on the specifically Designated Nationals and Blocked Persons
List maintained by the Office of Foreign Asset Control, Department of the Treasury pursuant to
Executive Order No. 13224, 66 Fed. Reg. 49079 (Sept. 25, 2001) or any other list of terrorists or
terrorist organizations maintained pursuant to any of the rules and regulations of Office of
Foreign Asset Control, Department of the Treasury or pursuant to any other applicable Executive
Orders (such lists are collectively referred to as the “OFAC Lists”). Assuming Borrower will not
knowingly enter into a lease with any party who is listed on the OFAC Lists. Assuming Borrower
shall immediately notify Lender if Assuming Borrower has knowledge that any member or beneficial
owner of Assuming Borrower is listed on the OFAC Lists or is (A) indicted on or (B) arraigned and
held over on charges involving money laundering or predicate crimes to money laundering. Assuming
Borrower shall immediately notify Lender if Assuming Borrower knows that any tenant is listed on
the OFAC Lists or (A) is convicted on, (B) pleads nolo contendere to, (C) is indicted on or (D) is
arraigned and held over on charges involving money laundering or predicate crimes to money
laundering. Assuming Borrower further represents and warrants to Lender that Assuming Borrower is
currently not on the OFAC Lists. None of Assuming Borrower, any subsidiary of Assuming Borrower or
any affiliate of Assuming Borrower or Assuming Indemnitor is (i) named on the list of Specially
Designated Nationals or Blocked Persons maintained by the U.S. Department of the Treasury’s Office
of Foreign Assets Control available at
http://www.treas.gov/offices/eotffc/ofac/sdn/index.html, or (ii) (A) an agency of the
government of a country, (B) an organization controlled by a country, or (C) a person residing in a
country that is subject to a sanctions program identified on the list maintained by the U.S.
Department of the Treasury’s Office of Foreign Assets Control and available at
http://www.treas.gov/offices/eotffc/ofac/sanctions/index.html, or as otherwise published
from time to time, as such program may be applicable to such agency, organization or person.

15. Additional Representations, Warranties and Covenants of Original Borrower. As a
condition of this Agreement, Original Borrower represent and warrant to Lender as follows:

(a) Original Borrower is a limited partnership duly organized, validly existing and in good
standing under the laws of the State of Georgia. Original Borrower has full power and authority to
enter into and carry out the terms of this Agreement and to convey the Property and assign the Loan
Documents.

(b) Gwinnett Medical Associates, LLP is a limited liability partnership duly organized,
validly existing and in good standing under the laws of the State of Georgia and is authorized to
transact business as a foreign limited liability partnership in each jurisdiction in which such
authorization is necessary for the operation of the business or properties of Original Borrower.
Gwinnett Medical Associates, LLP is the General Partner of Original Borrower and has full power and
authority to enter into this Agreement as General Partner on behalf of Original Borrower, and to
execute this Agreement.

(c) This Agreement, the Sales Agreement and all other documents executed by Original Borrower
in connection therewith constitute legal, valid and binding obligations of Original Obligors
enforceable in accordance with their respective terms. Neither the entry into nor the performance
of and compliance with this Agreement, the Sales Agreement and all other documents executed by
Original Borrower in connection therewith has resulted or will result in any violation of, or a
conflict with or a default under, any judgment, decree, order, mortgage, indenture, contract,
agreement or lease by which Original Borrower or any property of Original Borrower are bound or any
statute, rule or regulation applicable to Original Borrower.

(d) Original Borrower have not received any written notices from any governmental entity
claiming that either the Property or Original Borrower’s’ use of the Property is not presently in
compliance with any laws, ordinances, rules and regulations bearing upon the use and operation of
the Property including, without limitation, any notice relating to zoning laws or building code
regulations.

(e) The certified rent roll provided to Lender of even date herewith is a true, complete and
accurate summary of all tenant leases (“Tenant Leases” or individually, a “Tenant Lease”) affecting
the Property as of the date of this Agreement. No rent has been prepaid under any Tenant Lease
except rent for the current month. Each Tenant Lease has been duly executed and delivered by and,
to the knowledge of Original Borrower, is a binding obligation of, the respective tenant, and each
Tenant Lease is in full force and effect. Each Tenant Lease represents the entire agreement between
Original Borrower and the respective tenant and no Tenant Lease has been terminated, renewed,
amended, modified or otherwise changed without the prior written consent of Lender to the extent
required by the Loan Documents. The tenant under each Tenant Lease has taken possession of and is
in occupancy of the premises therein described and is open for business. Rent payments have
commenced under each Tenant Lease, and all tenant improvements in such premises and other
conditions to occupancy or rent commencement have been completed by Original Borrower or its
predecessor in interest. All obligations of the landlord under the Tenant Leases have been
performed, and no event has occurred and no condition exists that, with the giving of notice or
lapse of time or both, would constitute a default by Original Borrower under any Tenant Lease.
There are no offsets or defenses that any tenant has against the full enforcement of any Tenant
Lease by Original Borrower. Each Tenant Lease is fully and freely assignable by Original Borrower
without notice to or the consent of the tenant thereunder.

(f) Original Borrower is the current owner of the Property. To its knowledge, There are no
pending or threatened suits, judgments, arbitration proceedings, administrative claims, executions
or other legal or equitable actions or proceedings against or the Property, any pending or
threatened condemnation or annexation proceedings affecting the Property, or any agreements to
convey any portion of the Property or any rights thereto, that are not disclosed in this Agreement
including, without limitation, any pending or threatened administrative claim by any governmental
agency.

(g) Original Borrower has examined the ALTA, As-Built Survey (the “Survey”) performed on the
Property in connection with the closing of the Loan. As an inducement for Lender to consent to the
Assumption without requiring an update to the Survey, Original Borrower represents to Lender that
(i) there has been no improvement added at the Property, (ii) there has been no encroachment made
upon the Property, and (iii) no structural alteration has been made to the Property from the date
of the Survey to the date hereof without Lender’s prior written consent.]

(h) No representation or warranty of Original Borrower made in this Agreement contains any
untrue statement of material fact or omits to state a material fact necessary in order to make such
representations and warranties not misleading in light of the circumstances under which they are
made.

16. Incorporation of Recitals. Each of the Recitals set forth above in this Agreement
are incorporated herein and made a part hereof.

17. Property Remains as Security for Lender. All of the Property shall remain in all
respects subject to the lien, charge or encumbrance of the Mortgage. Except as expressly set forth
in this Agreement, nothing contained herein shall affect or be construed to release or affect the
liability of any party or parties who may now or hereafter be liable under or on account of the
Note or the Mortgage, nor shall anything contained herein affect or be construed to affect any
other security for the Note held by Lender.

18. No Waiver by Lender. Nothing contained herein shall be deemed a waiver of any of
Lender’s rights or remedies under any of the Loan Documents or under applicable law.

19. References. From and after the date hereof: (a) references in any of the Loan
Documents to any of the other Loan Documents will be deemed to be references to such other Loan
Documents as modified by this Agreement; (b) references in the Loan Documents to “Borrower,”
“Grantor” or “Mortgagor” shall hereafter be deemed to refer to Assuming Borrower; (c) references in
the Loan Documents to the “Guarantor,” “Indemnitor” or “Principal” shall hereafter be deemed to
refer to Assuming Indemnitor; and (d) all references to the term “Loan Documents” or “Security
Documents” in the Mortgage and Assignment shall hereinafter refer to the Loan Documents as defined
herein, this Agreement and all documents executed in connection with this Agreement.

20. Relationship with Loan Documents. To the extent that this Agreement is
inconsistent with the Loan Documents, this Agreement will control and the Loan Documents will be
deemed amended by this Agreement. Except as explicitly amended hereby, the Loan Documents shall
remain unchanged and in full force and effect.

21. Titles and Captions. Titles and captions of sections and subsections of this
Agreement have been inserted for convenience only and neither limit nor amplify the provisions of
this Agreement.

22. Partial Invalidity. Any provision of this Agreement or the Loan Documents held to
be illegal, invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective only to the extent of such illegality, invalidity or unenforceability, without
invalidating the remainder of such provision or the remaining provisions hereof or thereof or
affecting the legality, validity or enforceability of such provision in any other jurisdiction.

23. Entire Agreement. This Agreement and the documents contemplated to be executed
herewith constitute the entire agreement among the parties hereto with respect to the assumption of
the Loan. The Agreement supersedes all prior negotiations regarding the transfer of the Property
and the Assumption. This Agreement and the Loan Documents may only be amended, revised, waived,
discharged, released or terminated by a written instrument executed by the party against which
enforcement of the amendment, revision, waiver, discharge, release or termination is asserted. Any
alleged amendment, revision, waiver, discharge, release or termination of this Agreement which is
not in writing and signed by the parties shall not be effective as to any party.

24. Binding Effect. This Agreement and the documents contemplated to be executed in
connection herewith shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided, however, that the foregoing provision shall not be a
consent by Lender to any further sale, conveyance, assignment or transfer of the Property by
Assuming Borrower.

25. Multiple Counterparts. This Agreement may be executed in multiple counterparts,
each of which when so executed shall be deemed an original and shall be binding upon all parties
and all of which, taken together, shall constitute one and the same Agreement.

26. Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of the State where the Property is located.

27. Effective Date. This Agreement shall be effective as of the date of its execution
by the parties hereto and upon such date this Agreement shall be incorporated into the terms of the
Loan Documents.

28. Time of Essence. Time is of the essence with respect to all provisions of this
Agreement.

29. Cumulative Remedies. All remedies contained in this Agreement are cumulative and
Lender shall also have all other remedies provided at law and in equity contained in the Mortgage
and other Loan Documents. Such remedies may be pursued separately, successively or concurrently at
the sole discretion of Lender and may be exercised in any order and as often as occasion therefor
shall arise.

30. Construction. Each party hereto acknowledges that it has participated in the
negotiation of this Agreement and that no provision shall be construed against or interpreted to
the disadvantage of any party. Assuming Obligors and Original Borrower have had sufficient time to
review this Agreement, have been represented by legal counsel at all times, and have entered into
this Agreement voluntarily and without fraud, duress, undue influence or coercion of any kind.
Lender has not made a representation or warranty to any party except as set forth in this
Agreement.

31. WAIVER OF JURY TRIAL. ORIGINAL BORROWER, ASSUMING OBLIGORS AND LENDER, TO THE FULL
EXTENT PERMITTED BY LAW, HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY, WITH AND UPON THE ADVICE
OF COMPETENT COUNSEL, WAIVE, RELINQUISH AND FOREVER FOREGO THE RIGHT TO A TRIAL BY JURY IN ANY
ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO THE LOAN DOCUMENTS OR
THIS AGREEMENT.
