respect to any Hazardous Substances or other environmental condition at, on or under the Property
or other affected property, including all investigative, monitoring, removal, containment and

grant to the Indemnified Parties and their agents and employees access during normal business hours
to the Property as provided in Section 1.6 below, and a license to remove any items deemed by the
Indemnified Parties to be Hazardous Substances and to do all things the Indemnified Parties shall

1.5 Indemnification. The Indemnitors covenant and agree, at the Indemnitors’ sole
cost and expense, to indemnify, defend (at trial and appellate levels, and with attorneys,
consultants and experts acceptable to the Indemnified Parties), and hold the Indemnified Parties
harmless from and against any and all liens, damages (including, without limitation, consequential
damages), losses, liabilities, obligations, settlement payments, penalties, claims, judgments,
suits, proceedings, costs, disbursements or expenses of any kind or of any nature whatsoever
(including reasonable attorneys’, consultants’ and experts’ fees and disbursements actually
incurred in investigating, defending, settling or prosecuting any claim, litigation or proceeding)
which may at any time be imposed upon, incurred by or asserted against the Indemnified Parties or
the Property, and arising directly or indirectly from or out of, and except to the extent directly
caused by the gross negligence or willful misconduct of Indemnitors:

(a) the past, present or future presence, Release or threat of Release of any Hazardous
Substances on, in, under or affecting all or any portion of the Property or any surrounding
areas, regardless of whether or not caused by or within the control of any Indemnitor;

(b) the past, present or future violation of any Environmental Laws, relating to or
affecting the Property or the Borrower’s operations, whether or not caused by or within the
control of any Indemnitor;

(c) the failure by the Indemnitors to comply fully with the terms and conditions of
this Section 1;

(d) any misrepresentation or inaccuracy in or the breach of any representation or
warranty contained in this Section 1; or

(e) the enforcement of this Section 1, including any liabilities that arise as a result
of the actions taken or caused to be taken by the Indemnified Parties under this Section 1,
the cost of assessment, containment and/or removal of any and all Hazardous Substances from
all or any portion of the Property or any surrounding areas, the cost of any actions taken
in response to the presence, Release or threat of Release of any Hazardous Substances on,
in, under or affecting any portion of the Property or any surrounding areas to prevent or
minimize such Release or threat of Release so that it does not migrate or otherwise cause or
threaten danger to present or future public health, safety, welfare or the environment, and
costs incurred to comply with the Environmental Laws in connection with all or any portion
of the Property or any surrounding areas. The Indemnified Parties’ rights under this
Section 1 shall survive payment in full of the Borrower’s obligations under the Loan
Documents and shall be in addition to all other rights of the Indemnified Parties under the
Security Instrument, the Note and the other Loan Documents. The foregoing notwithstanding,
the Indemnitors’ obligations under this Section 1 with regard to any Post Transfer
Indemnification Responsibilities (as hereinafter defined) shall be limited to such
obligations directly or indirectly arising out of or resulting from any Hazardous Substances
that were present or released in, on, or around any part of the Property, or in the soil,
groundwater or soil vapor on or under the Property at any time before or while the Borrower
held title to or was in possession or control of the Property (the “Indemnitors’
Continuing Responsibility”); provided, however, that any Post Transfer Indemnification
Responsibilities incurred or suffered by the Indemnified Parties shall be presumed, unless
shown by a preponderance of the evidence to the contrary, to be the Indemnitors’ Continuing
Responsibility. “Post Transfer Indemnification Responsibilities” shall mean any
obligations hereunder to indemnify, defend, and hold the Indemnified Parties harmless
arising after the Indemnified Parties cease to hold a security interest in the Property or
acquire title to the Property as a result of foreclosure, deed in lieu of foreclosure, or
other transfer of the Property.

1.6 Site Visits, Observation and Testing. If Indemnified Parties have a reasonable
basis to suspect that Hazardous Materials in violation of the provisions of this Agreement are
present on the Property, the Indemnified Parties and their agents and representatives shall have
the right at any reasonable time upon prior notice and during normal business hours to enter and
visit the Property for the purposes of observing the Property, taking and removing soil or
groundwater samples, and conducting tests on any part of the Property; provided, however, that
there shall be no more than one such assessment per Property per 12-month period, unless Agent
reasonably believes a Material Adverse Changes has occurred which warrants a new assessment.
Indemnified Parties’ access and other rights shall be subject to the rights of tenants under leases
of the Property. The Indemnified Parties have no duty, however, to visit or observe the Property
or to conduct tests, and no site visit, observation or testing by any Indemnified Party shall
impose any liability on any Indemnified Party. In no event shall any site visit, observation or
testing by any Indemnified Party be a representation that Hazardous Substances are or are not
present in, on or under the Property, or that there has been or shall be compliance with any law,
regulation or ordinance pertaining to Hazardous Substances or any other applicable governmental
law. Neither the Borrower nor any other party is entitled to rely on any site visit, observation or
testing by any Indemnified Party. The Indemnified Parties owe no duty of care to protect the
Indemnitors or any other party against, or to inform the Indemnitors or any other party of, any
Hazardous Substances or any other adverse condition affecting the Property, provided the
Indemnified Parties shall make such environmental assessments available to Borrower. The
Indemnified Parties may in their discretion disclose to the Indemnitors or any other party any
report or findings made as a result of, or in connection with, any site visit, observation or
testing by the Indemnified Parties. The Indemnitors understand and agree that the Indemnified
Parties make no representation or warranty to the Indemnitors or any other party regarding the
truth, accuracy or completeness of any such report or findings that may be disclosed. The
Indemnitors also understand that, depending on the results of any site visit, observation or
testing by any Indemnified Party which are disclosed to the Indemnitors, the Indemnitors may have a
legal obligation to notify one or more environmental agencies of the results and that such
reporting requirements are site-specific and are to be evaluated by the Indemnitors without advice
or assistance from the Indemnified Parties. Any Indemnified Party shall give the Borrower
reasonable notice before entering the Property. Such Indemnified Party shall make reasonable
efforts to avoid interfering with the Borrower’s use of the Property in exercising any rights
provided in this Section 1.

2. REINSTATEMENT OF OBLIGATIONS. If at any time all or any part of any payment made
by the Borrower or received by the Indemnified Parties from the Borrower under or with respect to
this Agreement is or must be rescinded or returned for any reason whatsoever, including the
insolvency, bankruptcy or reorganization of any Indemnitor under any Debtor Relief Law (as defined
below), then the obligations of the Indemnitors hereunder shall, to the extent of the payment
rescinded or returned, be deemed to have continued in existence, notwithstanding such previous
payment made by the Indemnitors, or receipt of payment by an Indemnified Party, and the obligations
of the Indemnitors hereunder shall continue to be effective or be reinstated, as the case may be,
as to such payment, all as though such previous payment by the Indemnitors had never been made.

3. WAIVERS. To the extent permitted by law, each of the Indemnitors, for itself and
its successors, hereby waives and agrees not to assert or take advantage of:

(a) any right to require the Indemnified Parties to proceed against any other person or
to proceed against or exhaust any security held by the Indemnified Parties at any time or to
pursue any other remedy in the Indemnified Parties’ power or under any other agreement
before proceeding against the Indemnitors hereunder;

(b) any defense that may arise by reason of the incapacity, lack of authority, death or
disability of any other person or persons or the failure of the Indemnified Parties to file
or enforce a claim against the estate (in administration, bankruptcy or any other
proceedings) of any other person or person;

(c) demand, presentment for payment, notice of nonpayment, protest, notice of protest
and all other notices of any kind, or the lack of any thereof, including, without limiting

or additional indebtedness or obligation or of any action or non-action on the part of the
Indemnified Parties, any endorser or creditor of any of the Indemnitor or any other person
whomsoever under this or any other instrument in connection with any obligation or evidence
of indebtedness held by the Indemnified Parties;

(d) any right or claim of right to cause a marshalling of the assets of the
Indemnitors;

(e) any principle or provision of law, statutory or otherwise, which is or might be in
conflict with the terms and provisions of this Agreement;

(f) any duty on the part of the Indemnified Parties to disclose to the Indemnitors any
facts the Indemnified Parties may now or hereafter know about the Property, regardless of
whether the Indemnified Parties have reason to believe that any such facts materially
increase the risk beyond that which the Indemnitors intend to assume or have reason to
believe that such facts are unknown to the Indemnitors or have a reasonable opportunity to
communicate such facts to the Indemnitors, it being understood and agreed that the
Indemnitors are fully responsible for being and keeping informed of the condition of the
Property and of any and all circumstances bearing on the risk that liability may be incurred
hereunder;

(g) any lack of notice of disposition or of manner of disposition of any collateral for
the Loan;

the Indemnified Parties to collect or to obtain performance from any person or entities now
or hereafter liable for the payment and performance of any obligation hereby guaranteed;

(k) any assertion or claim that the automatic stay provided by 11 U.S.C. §362 (arising
upon the voluntary or involuntary bankruptcy proceeding of the Indemnitors) or any other
stay provided under any other debtor relief law (whether statutory, common law, case law or
otherwise) of any jurisdiction whatsoever, now or hereafter in effect, which may be or
become applicable, shall operate or be interpreted to stay, interdict, condition, reduce or
inhibit the ability of the Indemnified Parties to enforce any of their rights, whether now
or hereafter required, which the Indemnified Parties may have against the Indemnitors or the
collateral for the Loan; and

(l) any modifications of the Loan Documents or any obligation of the Indemnitors
relating to the Loan by operation of law or by action of any court, whether pursuant to the
Bankruptcy Reform Act of 1978, as amended or recodified (the “Bankruptcy Code”), or
under any other present or future state or federal law regarding bankruptcy, reorganization
or other relief to debtors (collectively, the “Debtor Relief Law”), or otherwise.

U.S.C. §9601 et seq.), as it may be amended from time to time, or any other
applicable federal, state or local laws, all such rights being hereby expressly reserved.

jurisdiction to be invalid, illegal or unenforceable, that provision shall be deemed severed from

shall be binding upon and inure to the benefit of the heirs, successors and assigns of the parties.

interest under the Note, the Security Instrument, the other Loan Documents, any or all servicing
rights with respect thereto, and this Agreement or grant participations. The Indemnified Parties

foregoing entities collectively referred to as an “Investor”) and each prospective
Investor, all documents, financial and other information which the Indemnified Parties now have or
may hereafter acquire relating to (a) the Loan; (b) the Property and its operation (including,

occupancy of the Property); and/or (c) any party connected with the Loan (including, without
limitation, the Borrower, any partner or member of the Borrower, any constituent partner or member
of the Borrower, and the Guarantor). The representations, warranties, obligations, covenants, and
indemnity obligations of the Indemnitors under this Agreement shall also benefit and apply with

pursuant hereto shall be given in the manner specified in the Security Instrument directed to the
parties at their respective addresses as provided therein.

4.11 No Waiver: Time of Essence; Interpretation; Counting of Days. The failure of any
party hereto to enforce any right or remedy hereunder, or to promptly enforce any such right or
remedy, shall not constitute a waiver thereof nor give rise to any estoppel against such party nor
excuse any of the parties hereto from their respective obligations hereunder. Any waiver of such
right or remedy must be in writing and signed by the party to be bound. Whenever used, the singular
number shall include the plural, the plural the singular, and the words “Indemnified Parties” and

(the “Guarantor”; the Borrower, Triumph and the Guarantor each being referred to herein as
an “Indemnitor” and collectively as the “Indemnitors”) to and for the benefit of
LASALLE BANK NATIONAL ASSOCIATION, a national banking association, together with its successors and

A. Pursuant to the terms of the Loan Agreement dated September 10, 2007 among the Agent, the
Banks and the Borrower (the “Loan Agreement”), the Banks have extended to the Borrower a credit
facility providing for loans in the principal amount of up to Fifty Million and 00/100 Dollars
($50,000,000.00) (subject to increase to One Hundred Twenty Million and 00/100 Dollars
[$120,000,000.00] under the terms set forth in the Loan Agreement) (the “Loan”).

B. The Loan is evidenced by that certain Promissory Note dated even date herewith (as amended,
modified and restated from time to time, the “Note”), executed by the Borrower and made
payable to the order of LaSalle secured by those certain Commercial Deed of Trust, Assignment of
Leases and Rents, Security Agreement and Fixture Filings dated as of even date herewith (jointly,
the “Security Instrument”), executed by a subsidiary of Borrower to and for the benefit of
the Agent, encumbering real property described on Exhibit “A” attached hereto, together
with the other collateral as described in the Security Instrument (the real property and other
collateral being collectively referred to as the “Property”). Capitalized terms used and
not specifically defined herein shall bear the same meaning as in the Security Instrument.

set forth below.

NOW, THEREFORE, to induce the Banks to extend the Loan to the Borrower and in consideration of
the foregoing premises and for other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Indemnitors hereby covenant and agree for the benefit of the

1.4 Notice and Access. The Indemnitors shall promptly notify the Indemnified Agent
in writing if any of the Indemnitors knows, suspects or believes there is or are (a) any Hazardous
Substances, other than those used by the property owner or tenants under leases at the Property in
the ordinary course of their businesses and in compliance with all Environmental Laws, present on
the Property; (b) any Release of Hazardous Substances in, on, under, from or migrating towards the

otherwise address any Release of Hazardous Substances at, on, in or in the vicinity of the
Property. The Indemnitors shall promptly, to the extent required of Indemnitors under applicable
Environmental Laws and at the Indemnitors’ sole cost and expense, take all reasonable actions with
respect to any Hazardous Substances or other environmental condition at, on or under the Property
or other affected property, including all investigative, monitoring, removal, containment and
remedial actions in accordance with all applicable Environmental Laws, including the payment, at no
expense to the Indemnified Parties, of all clean-up, administrative and enforcement costs of
applicable governmental agencies which may be asserted against the Property in all instances as
necessary to comply with and as required of Indemnitors pursuant to all applicable Environmental
Laws; (ii) protect human health or the environment; (iii) allow continued use, occupation, or
operation of the Property; and/or (iv) maintain the fair market value of the Property
(collectively, the “Completion of the Clean-up”). In the event the Indemnitors fail to do
so, the Indemnified Parties may, but shall not be obligated or have any duty to, cause the
Completion of the Clean-up of the Property. Upon reasonable prior notice, the Indemnitors hereby
grant to the Indemnified Parties and their agents and employees access during normal business hours
to the Property as provided in Section 1.6 below, and a license to remove any items deemed by the
Indemnified Parties to be Hazardous Substances and to do all things the Indemnified Parties shall
deem necessary to cause the Completion of the Clean-up of the Property.

1.5 Indemnification. The Indemnitors covenant and agree, at the Indemnitors’ sole
cost and expense, to indemnify, defend (at trial and appellate levels, and with attorneys,
consultants and experts acceptable to the Indemnified Parties), and hold the Indemnified Parties
harmless from and against any and all liens, damages (including, without limitation, consequential
damages), losses, liabilities, obligations, settlement payments, penalties, claims, judgments,
suits, proceedings, costs, disbursements or expenses of any kind or of any nature whatsoever
(including reasonable attorneys’, consultants’ and experts’ fees and disbursements actually
incurred in investigating, defending, settling or prosecuting any claim, litigation or proceeding)
which may at any time be imposed upon, incurred by or asserted against the Indemnified Parties or
the Property, and arising directly or indirectly from or out of, and except to the extent directly
caused by the gross negligence or willful misconduct of Indemnitors:

(a) the past, present or future presence, Release or threat of Release of any Hazardous
Substances on, in, under or affecting all or any portion of the Property or any surrounding
areas, regardless of whether or not caused by or within the control of any Indemnitor;

(b) the past, present or future violation of any Environmental Laws, relating to or
affecting the Property or the Borrower’s operations, whether or not caused by or within the
control of any Indemnitor;

(c) the failure by the Indemnitors to comply fully with the terms and conditions of
this Section 1;

(d) any misrepresentation or inaccuracy in or the breach of any representation or
warranty contained in this Section 1; or

(e) the enforcement of this Section 1, including any liabilities that arise as a result
of the actions taken or caused to be taken by the Indemnified Parties under this Section 1,
the cost of assessment, containment and/or removal of any and all Hazardous Substances from
all or any portion of the Property or any surrounding areas, the cost of any actions taken
in response to the presence, Release or threat of Release of any Hazardous Substances on,
in, under or affecting any portion of the Property or any surrounding areas to prevent or
minimize such Release or threat of Release so that it does not migrate or otherwise cause or
threaten danger to present or future public health, safety, welfare or the environment, and
costs incurred to comply with the Environmental Laws in connection with all or any portion
of the Property or any surrounding areas. The Indemnified Parties’ rights under this
Section 1 shall survive payment in full of the Borrower’s obligations under the Loan
Documents and shall be in addition to all other rights of the Indemnified Parties under the
Security Instrument, the Note and the other Loan Documents. The foregoing notwithstanding,
the Indemnitors’ obligations under this Section 1 with regard to any Post Transfer
Indemnification Responsibilities (as hereinafter defined) shall be limited to such
obligations directly or indirectly arising out of or resulting from any Hazardous Substances
that were present or released in, on, or around any part of the Property, or in the soil,
groundwater or soil vapor on or under the Property at any time before or while the Borrower
held title to or was in possession or control of the Property (the “Indemnitors’
Continuing Responsibility”); provided, however, that any Post Transfer Indemnification
Responsibilities incurred or suffered by the Indemnified Parties shall be presumed, unless
shown by a preponderance of the evidence to the contrary, to be the Indemnitors’ Continuing
Responsibility. “Post Transfer Indemnification Responsibilities” shall mean any
obligations hereunder to indemnify, defend, and hold the Indemnified Parties harmless
arising after the Indemnified Parties cease to hold a security interest in the Property or
acquire title to the Property as a result of foreclosure, deed in lieu of foreclosure, or
other transfer of the Property.

1.6 Site Visits, Observation and Testing. If Indemnified Parties have a reasonable
basis to suspect that Hazardous Materials in violation of the provisions of this Agreement are
present on the Property, the Indemnified Parties and their agents and representatives shall have
the right at any reasonable time upon prior notice and during normal business hours to enter and
visit the Property for the purposes of observing the Property, taking and removing soil or
groundwater samples, and conducting tests on any part of the Property; provided, however, that
there shall be no more than one such assessment per Property per 12-month period, unless Agent
reasonably believes a Material Adverse Changes has occurred which warrants a new assessment.
Indemnified Parties’ access and other rights shall be subject to the rights of tenants under leases
of the Property. The Indemnified Parties have no duty, however, to visit or observe the Property
or to conduct tests, and no site visit, observation or testing by any Indemnified Party shall
impose any liability on any Indemnified Party. In no event shall any site visit, observation or
testing by any Indemnified Party be a representation that Hazardous Substances are or are not
present in, on or under the Property, or that there has been or shall be compliance with any law,
regulation or ordinance pertaining to Hazardous Substances or any other applicable governmental
law. Neither the Borrower nor any other party is entitled to rely on any site visit, observation or
testing by any Indemnified Party. The Indemnified Parties owe no duty of care to protect the
Indemnitors or any other party against, or to inform the Indemnitors or any other party of, any
Hazardous Substances or any other adverse condition affecting the Property, provided the
Indemnified Parties shall make such environmental assessments available to Borrower. The
Indemnified Parties may in their discretion disclose to the Indemnitors or any other party any
report or findings made as a result of, or in connection with, any site visit, observation or
testing by the Indemnified Parties. The Indemnitors understand and agree that the Indemnified
Parties make no representation or warranty to the Indemnitors or any other party regarding the
truth, accuracy or completeness of any such report or findings that may be disclosed. The
Indemnitors also understand that, depending on the results of any site visit, observation or
testing by any Indemnified Party which are disclosed to the Indemnitors, the Indemnitors may have a
legal obligation to notify one or more environmental agencies of the results and that such
reporting requirements are site-specific and are to be evaluated by the Indemnitors without advice
or assistance from the Indemnified Parties. Any Indemnified Party shall give the Borrower
reasonable notice before entering the Property. Such Indemnified Party shall make reasonable
efforts to avoid interfering with the Borrower’s use of the Property in exercising any rights
provided in this Section 1.

2. REINSTATEMENT OF OBLIGATIONS. If at any time all or any part of any payment made
by the Borrower or received by the Indemnified Parties from the Borrower under or with respect to
this Agreement is or must be rescinded or returned for any reason whatsoever, including the
insolvency, bankruptcy or reorganization of any Indemnitor under any Debtor Relief Law (as defined
below), then the obligations of the Indemnitors hereunder shall, to the extent of the payment
rescinded or returned, be deemed to have continued in existence, notwithstanding such previous
payment made by the Indemnitors, or receipt of payment by an Indemnified Party, and the obligations
of the Indemnitors hereunder shall continue to be effective or be reinstated, as the case may be,
as to such payment, all as though such previous payment by the Indemnitors had never been made.

3. WAIVERS. To the extent permitted by law, each of the Indemnitors, for itself and
its successors, hereby waives and agrees not to assert or take advantage of:

(a) any right to require the Indemnified Parties to proceed against any other person or
to proceed against or exhaust any security held by the Indemnified Parties at any time or to
pursue any other remedy in the Indemnified Parties’ power or under any other agreement
before proceeding against the Indemnitors hereunder;

(b) any defense that may arise by reason of the incapacity, lack of authority, death or
disability of any other person or persons or the failure of the Indemnified Parties to file
or enforce a claim against the estate (in administration, bankruptcy or any other
proceedings) of any other person or person;

(c) demand, presentment for payment, notice of nonpayment, protest, notice of protest
and all other notices of any kind, or the lack of any thereof, including, without limiting
the generality of the foregoing, notice of the existence, creation or incurring of any new
or additional indebtedness or obligation or of any action or non-action on the part of the
Indemnified Parties, any endorser or creditor of any of the Indemnitor or any other person
whomsoever under this or any other instrument in connection with any obligation or evidence
of indebtedness held by the Indemnified Parties;

(d) any right or claim of right to cause a marshalling of the assets of the
Indemnitors;

(e) any principle or provision of law, statutory or otherwise, which is or might be in
conflict with the terms and provisions of this Agreement;

(f) any duty on the part of the Indemnified Parties to disclose to the Indemnitors any
facts the Indemnified Parties may now or hereafter know about the Property, regardless of
whether the Indemnified Parties have reason to believe that any such facts materially
increase the risk beyond that which the Indemnitors intend to assume or have reason to
believe that such facts are unknown to the Indemnitors or have a reasonable opportunity to
communicate such facts to the Indemnitors, it being understood and agreed that the
Indemnitors are fully responsible for being and keeping informed of the condition of the
Property and of any and all circumstances bearing on the risk that liability may be incurred
hereunder;

(g) any lack of notice of disposition or of manner of disposition of any collateral for
the Loan;

(h) any invalidity, irregularity or unenforceability, in whole or in part, of any one
or more of the Loan Documents;

(i) any lack of commercial reasonableness in dealing with the collateral for the Loan;

(j) any deficiencies in the collateral for the Loan or any deficiency in the ability of
the Indemnified Parties to collect or to obtain performance from any person or entities now
or hereafter liable for the payment and performance of any obligation hereby guaranteed;

(k) any assertion or claim that the automatic stay provided by 11 U.S.C. §362 (arising
upon the voluntary or involuntary bankruptcy proceeding of the Indemnitors) or any other
stay provided under any other debtor relief law (whether statutory, common law, case law or
otherwise) of any jurisdiction whatsoever, now or hereafter in effect, which may be or
become applicable, shall operate or be interpreted to stay, interdict, condition, reduce or
inhibit the ability of the Indemnified Parties to enforce any of their rights, whether now
or hereafter required, which the Indemnified Parties may have against the Indemnitors or the
collateral for the Loan; and

(l) any modifications of the Loan Documents or any obligation of the Indemnitors
relating to the Loan by operation of law or by action of any court, whether pursuant to the
Bankruptcy Reform Act of 1978, as amended or recodified (the “Bankruptcy Code”), or
under any other present or future state or federal law regarding bankruptcy, reorganization
or other relief to debtors (collectively, the “Debtor Relief Law”), or otherwise.

4. GENERAL PROVISIONS.

4.1 Full Recourse. All of the terms and provisions of this Agreement are full
recourse obligations of the Indemnitors and not restricted by any limitation on personal liability.

4.2 Secured Obligations. The Indemnitors hereby acknowledge that the obligations of
the Indemnitors under this Agreement are secured by the lien of the Security Instrument and the
security interests and other collateral described in the Security Instrument and the other Loan
Documents.

4.3 Survival. This Agreement shall be deemed to be continuing in nature and shall
remain in full force and effect and shall survive the payment of the indebtedness evidenced and
secured by the Loan Documents and the exercise of any remedy by the Indemnified Parties under the
Security Instrument or any of the other Loan Documents, including any foreclosure or deed in lieu
thereof, even if, as a part of such remedy, the Loan is paid or satisfied in full.

4.4 No Recourse Against the Indemnified Parties. The Indemnitors shall not have any
right of recourse against the Indemnified Parties by reason of any action the Indemnified Parties
may take or omit to take under the provisions of this Agreement or under the provisions of any of
the Loan Documents.

4.5 Reservation of Rights. Nothing contained in this Agreement shall prevent or in
any way diminish or interfere with any rights or remedies, including the right to contribution,
which the Indemnified Parties may have against the Indemnitors or any other party under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980 (codified at Title 42
U.S.C. §9601 et seq.), as it may be amended from time to time, or any other
applicable federal, state or local laws, all such rights being hereby expressly reserved.

4.6 Rights Cumulative; Payments. The Indemnified Parties’ rights under this Agreement
shall be in addition to all rights of the Indemnified Parties under the Note, the Security
Instrument and the other Loan Documents. Further, payments made by the Indemnitors under this
Agreement shall not reduce in any respect the Borrower’s obligations and liabilities under the
Note, the Security Instrument and the other Loan Documents.

4.7 No Limitation on Liability. Each of the Indemnitors hereby consents and agrees
that the Indemnified Parties may at any time and from time to time without further consent from the
Indemnitors do, permit or cause any of the following events, and the liability of the Indemnitors
under this Agreement shall be unconditional and absolute and shall in no way be impaired or limited
by the occurrence of any of the following events, whether occurring with or without notice to the
Indemnitors, or with or without consideration: (a) any extensions of time for performance required
by any of the Loan Documents or extension or renewal of the Note; (b) any sale, assignment or
foreclosure of the Note, the Security Instrument or any of the other Loan Documents or any sale or
transfer of the Property; (c) any change in the composition of any of the Indemnitors; (d) the
accuracy or inaccuracy of the representations and warranties made by the Indemnitors herein or in
any of the Loan Documents; (e) the release of any of the Indemnitors or of any other person or
entity from performance or observance of any of the agreements, covenants, terms or conditions
contained in any of the Loan Documents by operation of law, the Indemnified Parties’ voluntary act
or otherwise; (f) the release or substitution in whole or in part of any security for the Loan; (g)
the Agent’s failure to record the Security Instrument or to file any financing statement (or the
Agent’s improper recording or filing thereof) or to otherwise perfect, protect, secure or insure
any lien or security interest given as security for the Loan; (h) the modification of the terms of
any one or more of the Loan Documents; or (i) the taking or failure to take any action of any type
whatsoever. No such action which the Indemnified Parties shall take or fail to take in connection
with the Loan Documents or any collateral for the Loan, nor any course of dealing with the
Indemnitors or any other person, shall limit, impair or release the Indemnitors’ obligations
hereunder, affect this Agreement in any way or afford the Borrower any recourse against the
Indemnified Parties. Nothing contained in this Paragraph shall be construed to require the
Indemnified Parties to take or refrain from taking any action referred to herein.

4.8 Entire Agreement; Amendment; Severability. This Agreement contains the entire
agreement between the parties respecting the matters herein set forth and supersedes (except as to
the Security Instrument) all prior agreements, whether written or oral, between the parties
respecting such matters. Any amendments or modifications hereto, in order to be effective, shall
be in writing and executed by the parties hereto. If any provision or obligation under this
Agreement or any of the other Loan Documents shall be determined by a court of competent
jurisdiction to be invalid, illegal or unenforceable, that provision shall be deemed severed from
the Loan Documents and the validity, legality and enforceability of the remaining provisions or
obligations shall remain in full force as though the invalid, illegal or unenforceable provision
had never been a part of the Loan Documents.

4.9 Governing Law; Binding Effect. This Agreement shall be governed by and construed
in accordance with the laws of the State of Illinois, except to the extent that the applicability
of any of such laws may now or hereafter be preempted by Federal law, in which case such Federal
law shall so govern and be controlling. The terms, covenants and conditions of this Agreement
shall be binding upon and inure to the benefit of the heirs, successors and assigns of the parties.
The Indemnified Parties and any successor may, at any time, sell, transfer, or assign their
interest under the Note, the Security Instrument, the other Loan Documents, any or all servicing
rights with respect thereto, and this Agreement or grant participations. The Indemnified Parties
may forward to each purchaser, transferee, assignee, servicer, participant or investor (all of the
foregoing entities collectively referred to as an “Investor”) and each prospective
Investor, all documents, financial and other information which the Indemnified Parties now have or
may hereafter acquire relating to (a) the Loan; (b) the Property and its operation (including,
without limitation, copies of all leases, subleases or any other agreements concerning the use and
occupancy of the Property); and/or (c) any party connected with the Loan (including, without
limitation, the Borrower, any partner or member of the Borrower, any constituent partner or member
of the Borrower, and the Guarantor). The representations, warranties, obligations, covenants, and
indemnity obligations of the Indemnitors under this Agreement shall also benefit and apply with
respect to any purchaser, transferee, assignee, participant, servicer or investor.

4.10 Notices. All notices or other communications required or permitted to be given
pursuant hereto shall be given in the manner specified in the Security Instrument directed to the
parties at their respective addresses as provided therein.

4.11 No Waiver: Time of Essence; Interpretation; Counting of Days. The failure of any
party hereto to enforce any right or remedy hereunder, or to promptly enforce any such right or
remedy, shall not constitute a waiver thereof nor give rise to any estoppel against such party nor
excuse any of the parties hereto from their respective obligations hereunder. Any waiver of such
right or remedy must be in writing and signed by the party to be bound. Whenever used, the singular
number shall include the plural, the plural the singular, and the words “Indemnified Parties” and
“Indemnitors” shall include their respective successors, assigns, heirs, executors and
administrators. The word “include(s)” means “include(s), without limitation”, and the word
“including” means “including, but not limited to”. This Agreement is subject to enforcement at law
or in equity, including actions for damages or specific performance. Time is of the essence of
