1. The foregoing background information is hereby incorporated herein as if herein set forth verbatim.

2. Landlord and Tenant hereby modify the Leases as follows:

A. Tenant’s rights to cancel the Leases prior to their respective expiration dates are hereby terminated and waived, and, except as extended below, the Leases shall remain in full force and effect for their full terms as set forth on Exhibit “A”.

B. The Lease dated as of September 30, 1996, as amended, for the ground floor portion of the Building now occupied by Tenant commonly known as Suite 100 is extended to December 31, 2011.  That Lease shall expire pursuant to its terms on December 31, 2006 with respect to floors 2, 3, 4, 6, 9, 10, 20 and 21 of the Building.

From and after January 1, 2007, the rent for the ground floor portion of the Building under the extended lease shall be $16,628.00 per month, and Tenant’s share of any increase in Property Taxes and Operating Costs under Paragraph 20 of the extended ground floor lease shall be 3.10%.

E. All of the foregoing extensions shall be on the same terms and conditions of Tenant’s existing leases for the space in question, except:

(i) Tenant shall have the right to sublease any such leased space without the consent of Buyer or its successor owners so long as the sublessee shall utilize the subleased space for a purpose generally consistent with usage in other first class downtown Los Angeles multi-story office buildings, and so long as such sublessee is not an existing tenant of the Building.  In addition, there shall be no sublease to a consulate or a tenant that will add to utility, maintenance, security or other building costs above those of a normal office tenant.  There shall be no restaurant or club on the ground floor of the Building;

(ii) Tenant shall be entitled to maintain its roof top identification sign as long as it remains the responsible (as contrasted to occupying) party under its leases for the ground floor, fifth floor and eleventh floor space in the Building;

(iii) The right to maintain such roof top sign shall pass to any successor subtenant of Tenant for entire of such ground floor, fifth floor and eleventh floor space; and

2

(iv) Sixty (60) days prior to November 10, 2009, Tenant must either extend the maturity date of both the fifth floor and the eleventh floor leases to November 10, 2010, or extend one of the leases to November 10, 2011, in which event the other lease shall expire on November 10, 2009.  If Tenant fails to make such election, it shall be deemed to have elected to extend both the fifth floor and eleventh floor leases to November 10, 2010.  No lease extension will be provided for any other portion of the Tenant’s currently leased premises in the Property.

3. Except as herein provided, the Leases remain unamended and in full force and effect.
