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

1. Defined Terms. All capitalized terms used herein and not otherwise defined
shall have the meaning given to that term in the Deed of Trust.

2. Amendments to Deed of Trust. The Deed of Trust is hereby amended as follows:

(a) Pursuant to Amendment No. 2 to Credit Agreement, the maturity date of
certain of the Obligations has been extended to a date not later than
October 10, 2017.

(b) Section 3.5 of the Deed of Trust is hereby amended by deleting such section
in its entirety and replacing it with the following:

3.5 Insurance. Grantor will keep or cause to be kept the Mortgaged Property
insured against such risks and shall purchase such additional insurance to the
extent that is required from time to time pursuant to Section 9.3 of the Credit
Agreement. Without limiting the generality of the foregoing, if any portion of
the Mortgaged Property is located in an area identified by the Federal Emergency
Management Agency as an area having special flood hazards and in which flood
insurance has been made available under the National Flood Insurance Act of 1968
(or any amendment or successor act thereto), then Grantor shall maintain, or
cause to be maintained, with a financially sound and reputable insurer, flood
insurance in an amount sufficient to comply with all applicable rules and
regulations promulgated pursuant to such Act.

(c) Section 16 of the Deed of Trust is hereby amended by deleting such section
in its entirety and replacing it with the following:

16. REMEDIES NOT EXCLUSIVE

(a) Beneficiary and Trustee shall be entitled to enforce payment and performance
of the Obligations and to exercise all rights and powers under this Deed of
Trust or under any of the other Security Documents or other agreement or any
laws now or hereafter in force, notwithstanding some or all of the Obligations
may now or hereafter be otherwise secured, whether by deed of trust, mortgage,
security agreement, pledge, lien, assignment or otherwise. Neither the
acceptance of this Deed of Trust nor its enforcement, shall prejudice or in any
manner affect Beneficiary’s or Trustee’s right to realize upon or enforce any
other security now or hereafter held by Beneficiary or Trustee, it being agreed
that Beneficiary and Trustee shall be entitled to enforce this Deed of Trust and
any other security now or hereafter held by Beneficiary or Trustee in such order
and manner as Beneficiary or Trustee may determine in its absolute discretion.
No remedy herein conferred upon or reserved to Trustee or Beneficiary is
intended to be exclusive of any other remedy herein or by law provided or
permitted, but each shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law or in equity or by
statute. Every power or remedy given by any of the Security Documents to
Beneficiary or Trustee or to which either may otherwise be entitled, may be
exercised, concurrently or independently, from time to time and as often as may
be deemed expedient by Beneficiary or Trustee, as the case may be. In no event
shall Beneficiary or Trustee, in the exercise of the remedies provided in this
Deed of Trust (including, without limitation, in connection with the assignment
of Rents to Beneficiary, or the appointment of a receiver and the entry of such
receiver on to all or any part of the Mortgaged Property), be

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

deemed a “mortgagee in possession,” and neither Beneficiary nor Trustee shall in
any way be made liable for any act, either of commission or omission, in
connection with the exercise of such remedies.

(b) Without limiting the generality of Section 16(a), except as otherwise
provided in Section 16(c) below, neither the enforcement of any of the remedies
under Sections 5 and 16 hereof, the security interests under Section 9, the
assignment of Rents under Section 10, nor any other remedies afforded to
Beneficiary under the Security Documents, at law or in equity shall cause
Beneficiary, any Lender or Trustee to be deemed or construed to be a mortgagee
in possession of the Mortgaged Property, to obligate Beneficiary, any Lender or
Trustee to lease the Mortgaged Property or attempt to do so, or to take any
action, incur any expense, or perform or discharge any obligation, duty or
liability whatsoever under any of the Leases or otherwise.

(c) Notwithstanding the provisions of Section 16(b) above, Beneficiary shall not
obtain title to a deed in lieu of foreclosure or otherwise, or take any other
action with respect to the Mortgaged Property, if, as a result of any such
action, Beneficiary could, in its reasonable judgment be considered to hold
title to, to be a “mortgagee-in-possession” of, or to be an “owner” or
“operator” of the Mortgaged Property within the meaning of Comprehensive
Environmental Response, Compensation and Liability Act Of 1980 (42 U.S.C.
Sections 9601 et seq.), as amended, or any comparable law, unless:

(i) Beneficiary has previously and reasonably determined, based on a Phase I
environmental site assessment (and any additional environmental testing that
Beneficiary deems necessary and prudent) of such Mortgaged Property conducted by
an independent third party who regularly conducts Phase I environmental site
assessments and performed during the 12-month period preceding any such
acquisition of title or other action, that the Mortgaged Property is in
compliance with applicable environmental laws and regulations and there are no
circumstances or conditions present at the Mortgaged Property relating to the
use, management or disposal of Hazardous Materials for which investigation,
testing, monitoring, containment, clean-up or remediation could be required
under any applicable environmental laws and regulations; or

(ii) in the event that the determination described in clause (i) above cannot be
made, Beneficiary has previously and reasonably determined, on the same basis as
described in clause (i) above, that it would maximize the recovery to the
Secured Parties on a present value basis to acquire title to or possession of
the Mortgaged Property and to take such remedial, corrective and/or other
further actions as are necessary to bring the Mortgaged Property into compliance
with applicable environmental laws and regulations and to appropriately address
any of the circumstances and conditions referred to in clause (i) above.

(d) Beneficiary shall undertake, in good faith, reasonable efforts to make the
determination referred to in clause (ii) above, and may conclusively rely on the
Phase I environmental site assessment referred to above, and upon an opinion of
counsel, in making such determination. The cost of any such Phase I
environmental site assessment and any such opinion of counsel, and the cost of
any Phase II environmental site assessment, additional environmental testing

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

and remedial, corrective or other further action contemplated by clause (i) or
clause (ii) above, shall be paid at the sole expense of Grantor.

(e) If the environmental testing contemplated by Section 16(b) above establishes
that any of the conditions set forth in clause (i) have not been satisfied with
respect to the Mortgaged Property, Beneficiary shall take such action (other
than proceeding against the Mortgaged Property) and, at such time as it deems
appropriate, may release all or a portion of such Mortgaged Property from the
lien of this Deed of Trust, provided that prior to the release of all or a
portion of the Mortgaged Property from the lien of this Deed of Trust
(a) Beneficiary shall have notified the Lenders in writing of its intention to
so release all or a portion of such Mortgaged Property and (b) the holders of a
majority of the outstanding principal balance of the Obligations shall not have
objected to such release within thirty (30) days of the distribution of the last
of such notices.

(d) Section 29 of the Deed of Trust is hereby amended by deleting such section
in its entirety and replacing it with the following:

29. MATURITY OF OBLIGATIONS

The latest maturity date of the Obligations is October 10, 2017.

3. No Other Amendments. Except as amended hereby, the Deed of Trust is
acknowledged to be in full force and effect as written. Nothing in this
Amendment is intended to waive any rights or remedies of the Beneficiary under
the Deed of Trust, or any defaults of Grantor under the Deed of Trust. The Deed
of Trust shall continue to be a valid and subsisting lien against the Mortgaged
Property. The Grantor, in order to continue to secure the payment of the
Obligations, hereby confirms and restates [(a)] the conveyance pursuant to the
Deed of Trust to the Beneficiary of the Mortgaged Property[ and (b) the grant
pursuant to the Deed of Trust of a security interest in the Fixtures]. Nothing
contained in this Amendment shall be construed as (a) a novation of the
Obligations or (b) a release or waiver of all or any portion of the conveyance
to the Beneficiary of the Mortgaged Property or the grant to the Beneficiary of
a security interest in the Fixtures pursuant to the Deed of Trust.

4. No Oral Agreements. THIS WRITTEN AMENDMENT, TOGETHER WITH ALL OF THE OTHER
LOAN DOCUMENTS AND THE AMENDMENTS THERETO, AS AMENDED HEREBY, REPRESENTS THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

5. Multiple Counterparts. This Amendment may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
agreement, and any of the parties to this Amendment may execute this Amendment
by signing any of the counterparts.

6. Representations and Warranties. The Grantor hereby represents and warrants
that the representations and warranties made by it in the Deed of Trust are true
and complete on and as of the date hereof as if made on and as of the date
hereof.
