This Amendment No. 3 (this “Amendment”) is executed as of January 21, 2013, between NOP 301 CONGRESS LP, a Texas limited partnership (“Landlord”), and WHALESHARK MEDIA, INC., a Delaware corporation (“Tenant”), for the purpose of amending the Lease Agreement between Landlord and Tenant dated May 24, 2011 (the “Original Lease”). The Original Lease, as amended by the Confirmation of Commencement Date dated September 21, 2011, Amendment No. 1 dated November 14, 2011 (“Amendment No. 1”), Confirmation of Effective Date dated September 13, 2012, and Amendment No. 2 dated November 9, 2012 (“Amendment No. 2”), is referred to herein as the “Lease”. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Original Lease.

RECITALS:

Pursuant to the terms of the Lease, Tenant is currently leasing Suites 700, 825 and 850, consisting of 35,504 rentable square feet of space in the aggregate (the “Existing Premises”), in the Building located at 301 Congress Avenue, Austin, TX 78701, and commonly known as 301 Congress. Pursuant to Amendment No. 2, Tenant has also agreed to lease Suites 400, 500 and 600 (collectively, the “Second Expansion Premises”) in the Building, pursuant to the terms and conditions of Amendment No. 2. Prior to taking possession of the Second Expansion Premises, Tenant desires to lease, on a temporary basis, Suite 210 in the Building containing approximately 2,658 rentable square feet (the “Suite 210 Premises”), Suite 520 in the Building, containing approximately 1,255 rentable square feet (the “Suite 520 Premises”), Suite 555 in the Building, containing approximately 1,432 rentable square feet (the “Suite 555 Premises”), and Suite 560 in the Building, containing approximately 1,822 rentable square feet (the “Suite 560 Premises”) (each as depicted on Exhibit A hereto), and Landlord has agreed to lease such space to Tenant on the terms and conditions contained herein. As used herein, the Suite 210 Premises, the Suite 520 Premises, the Suite 555 Premises and the Suite 560 Premises shall be collectively referred to herein as the “Temporary Premises”).

AGREEMENTS:

For valuable consideration, whose receipt and sufficiency are acknowledged, Landlord and Tenant agree as follows:

1. Temporary Premises; Tenant’s Proportionate Share; Acceptance. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Temporary Premises on the terms and conditions of the Lease, as modified hereby; accordingly, (a) from and after the Suite 210 Effective Date (defined below), the term “Premises” shall refer collectively to the Existing Premises and the Suite 210 Premises, and, except as otherwise provided herein, Tenant’s Proportionate Share shall be increased to 9.12%, which is the percentage obtained by dividing the number of rentable square feet in the Premises (38,162) by the number of rentable square feet in the Building (418,338); (b) from and after the Suite 520 Effective Date (defined below), the term “Premises” shall refer collectively to the Existing Premises, the Suite 210 Premises, and the Suite 520 Premises, and, except as otherwise provided herein, Tenant’s Proportionate Share shall be increased to 9.42%, which is the percentage obtained by dividing the number of rentable square feet in the Premises (39,417) by the number of rentable square feet in the Building (418,338); (c) from and after the Suite 560 Effective Date (defined below), the term “Premises” shall refer collectively to the Existing Premises, the Suite 210 Premises, the Suite 520 Premises, and the Suite 560 Premises, and, except as otherwise provided herein, Tenant’s Proportionate Share shall be increased to 9.86%, which is the percentage obtained by dividing the number of rentable square feet in the Premises (41,239) by the number of rentable square feet in the Building (418,338); and (d) from and after the Suite 555 Effective Date (defined below), the term “Premises” shall refer collectively to the Existing Premises and the entire Temporary Premises, and, except as otherwise provided herein, Tenant’s Proportionate Share shall be increased to 10.20%, which is the percentage obtained by dividing the number of rentable square feet in the Premises (42,671) by the number of rentable square feet in the Building (418,338). Tenant accepts the Temporary Premises in their “AS-IS” condition and Landlord shall not be required to perform any demolition work or tenant finish-work therein or to provide any allowances therefor. Landlord and Tenant stipulate that the number of rentable square feet in the Existing Premises, the Temporary Premises and the Building are correct. For the avoidance of doubt, should any portions of the Temporary Premises become part of the Premises in a different order than contemplated above (i.e., Suite 210 Premises, then Suite 520 Premises, then Suite 560 Premises, then Suite 555 Premises), the calculations of the Premises and Tenant’s Proportionate Share shall be appropriately adjusted.
