On August 19, 2015, RetailMeNot, Inc. (the “Company”) entered into Amendment No. 4 (the “Fourth Amendment”) with NOP 301 Congress LP (the “Landlord”), which modifies the terms of the Lease Agreement dated May 24, 2011, as amended (the “Original Lease”) by and between the Company and the Landlord. Pursuant to the Fourth Amendment, the Company leased an additional 4,518 square feet of office space (the “Expansion Space”) at the Company’s corporate headquarters located at 301 Congress Avenue, Austin, Texas (the “Building”), bringing the total square footage subject to the Original Lease to approximately 100,000 square feet. The Fourth Amendment provides for base rent on the Expansion Space of $28.50 per square foot plus the Company’s proportionate share of common expenses, with specified annual rent increases for all of the premises subject to the Original Lease, including the Expansion Space.

The lease term for the Expansion Space is expected to commence on or about February 1, 2016 and it expires 96 months from the date of commencement. The Company also extended the lease term on the remainder of the premises subject to the Original Lease to expire at the same time as the Expansion Space, rather than July 31, 2020 as originally provided. The Landlord also granted the Company an option to lease an additional approximately 20,000 square feet of office space (the “Additional Expansion Space”) in the Building. In the event that the Company elects not to exercise its option on the Additional Expansion Space, then the term of the entire premises subject to the Original Lease, including the Expansion Space, would be extended for an additional year. The Company has an option to extend the term of the Original Lease (including the Expansion Premises and, if applicable, the Additional Expansion Space) for an additional five years.

The Company and Landlord had previously entered into Amendment No. 2 dated November 9, 2012 (the “Second Amendment”) pursuant to which the Landlord granted the Company the right of first offer (the “Original Right of First Offer”) on any offer to a third party for any contiguous space of at least 10,000 square feet in the Building, subject to certain conditions and restrictions. Pursuant to Amendment No. 4, the Landlord granted the Company an additional right of first offer on any offer to a third party with respect to the 10^th and 11^th floors in the Building (the “Additional Right of First Offer”), subject to certain conditions and restrictions. The Additional Right of First Offer is primary to, and replaces, the Original Right of First Offer with respect to space located on the 10^th and 11^th floors in the Building.

A copy of the Fourth Amendment is attached hereto as Exhibit 10.1 and is incorporated herein by reference. Copies of the Lease Agreement dated May 24, 2011, Amendment No. 1 to Lease Agreement dated November 14, 2012, the Second Amendment and Amendment No. 3 to Lease Agreement dated January 21, 2013 were filed as Exhibits 10.6.1, 10.6.2, 10.6.3 and 10.6.4, respectively, to the Company’s Draft Registration Statement (File No. 377-00145) filed with the Securities and Exchange Commission on April 5, 2013. The foregoing descriptions of the Original Lease, the Second Amendment and the Fourth Amendment are qualified in their entirety by reference to the full text of each of these documents.
