Attention: Mr. Tod A. Brown, Senior Vice President

Re:      Lease at 14400 Hertz Quail Springs Parkway, Oklahoma City, Oklahoma (the “Property”)

Ladies and Gentlemen:

The undersigned certifies to Moriah Real Estate Company, LLC, a Texas limited liability company (together with its successors, assigns and lenders, “Moriah”) and agrees with Moriah, as a potential purchaser of the referenced property and its mortgage lender with respect to the Property, that all of the following are true and correct as of the date of this estoppel certificate:

1.          The undersigned is the tenant (“Tenant”) under a lease dated May 30, 1997 (the “Lease”) naming The Fund IX, Fund X, Fund XI and REIT Joint Venture as landlord (together with any predecessors, successors and/or assigns, the “Landlord”) for suite no. 100 (the “Leased Premises”), located at the Property.

2.          The Lease is in full force and effect. The Lease has not been amended, modified or supplemented except as reflected in paragraph 12 below. There are no agreements or understandings, whether written or oral, between Tenant and Landlord with respect to the Lease, the Leased Premises or the Property except as reflected in paragraph 12 below.

3.          Tenant has accepted possession of and occupies the entire Leased Premises under the Lease. The term of the Lease expires on January 31, 2015.

4.          The monthly fixed, minimum or basic rent under the Lease is $63,142.88 and has been paid through the month of September       , 2010. All additional rent, percentage rent, Tenant’s proportionate share of real estate taxes and insurance, common area maintenance charges, contributions to any merchant’s association or promotional fund and all other sums or charges due and payable under the Lease by Tenant have been paid in full. No rents or other charges have been paid for more than one (1) month in advance of the due date thereof.

5.          The amount of the security deposit held by the Landlord under the Lease is $0.00.

6.          To the best of Tenant’s knowledge, both Tenant and Landlord have performed all of their respective obligations under the Lease and Tenant has no knowledge of any event which with the giving of notice, the passage of time, or both, would constitute a default by Landlord under the Lease.

7.          Tenant has no unresolved claims against Landlord and claims no offset or defense to enforcement of any of the terms of the Lease.

8.          All improvements required to be completed by Landlord have been completed and there are no sums due to Tenant from Landlord.

9.          Tenant has not assigned the Lease and has not subleased the Leased Premises or any part thereof.

10.        Tenant has no right or option pursuant to the Lease or otherwise to purchase all or any part of

Revised Exhibit “H” – Page 1

the Leased Premises or the Property. Tenant does not have any right or option for additional space in the Property.

11.        No voluntary actions or, to Tenant’s best knowledge, involuntary actions are pending against Tenant under the bankruptcy laws of the United States or any state thereof.

12.        Attached hereto as Exhibit A is a true copy of the Lease and all amendments, modifications and supplements thereto, including the following:

13.        Tenant has not received notice of any assignment, hypothecation, mortgage or pledge of Landlord’s interest in the Lease or the rents or other amounts payable thereunder.

14.        Tenant utilized $405,044.64 of the Construction Allowance (as defined in the Third Amendment), so the amount of the Termination Payment (as defined in the Third Amendment) is $284,835.15.

15.        The raised computer floor, which constitutes the grade level finished floor in two main conference rooms in the Leased Premises and the adjacent server room off of the main conference room in the Leased Premises, is part of the Leased Premises and will be the property of Landlord upon the expiration or earlier termination of the Lease.

16.        The Caterpillar generator located on the exterior of the Building (as defined in the Lease) and affixed to a concrete support pad and containment tank is part of the Leased Premises and will be the property of Landlord upon the expiration or earlier termination of the Lease.

17.        The undersigned individual hereby certifies that he or she is duly authorized to sign, acknowledge and deliver this letter on behalf of Tenant.

Tenant acknowledges that the Moriah above will rely on this letter in purchasing the Property and/or in making one or more loans secured by the Property. The information contained in this letter shall be for the benefit of and can be relied upon without limitation by Landlord and any such purchaser and/or any mortgage lender.

Notwithstanding any other provision of this certificate to the contrary, nothing herein shall be construed as a waiver of (i) any right which Tenant may have to audit any payments made under the Lease, (ii) any right to claim that any such payments were not properly charged or calculated in accordance with the Lease, or (iii) any right to recover from the applicable present, former or future landlord (including Landlord) any such payments made to such landlord which were in excess of the amount properly due under the Lease.
