Market Indicators Relative to prior period VACANCY NET ABSORPTION CONSTRUCTION RENTAL RATE** Q3 2018 Q4 2018 Coworking, technology and healthy initiatives drive office transformation Office properties are evolving throughout primary U.S. markets due to coworking space popularity, enhanced technology and healthconscious initiatives; all three trends are interwoven with one another and are transforming the nature of the traditional office building. Coworking is defined as a group of people (often from various companies) using a shared workspace. The popularity of this modern way of working is increasing exponentially. Not only does coworking allow start-ups and small businesses to work in open, contemporary spaces with amenities they may otherwise be unable to afford, it also provides larger companies the opportunity to test the waters in a new market by using swing space or a small satellite office prior to making a long-term commitment in a new location. In addition, office owners are able to upgrade and fully lease the remaining spaces in their buildings through the coworking model. Coworking spaces will differ from market to market, but will likely have the following similarities: high-end finishes, collaboration space and amenities; advanced technology, with the ability to work remotely; and 24-hour access to accommodate varying work hours. Not only is workspace evolving, new forms of technology, such as driverless vehicles, may transform office buildings on a larger scale and sooner than expected. While this trend is still in the testing phases and it is undeterminable when it will turn from future hype to a real-world everyday application, if it continues Note: Construction is the change in Under Construction. *Projected **Rental rates for current quarter are for CBD. Rent forecast is for metro-wide rents.

as is expected in fair-weather areas, office building owners will need to plan ahead to successfully adapt to it. According to Forbes, Uber bought 24,000 SUVs from Volvo to form a fleet of driverless vehicles that could hit the roads as early as 2019. Due to driverless transportation and the future of less all day parking needs, office building owners may eventually transform excess garage space into mixed-use environments. This mixed-use model will increase building foot traffic and add various everyday conveniences while remaining lucrative to the garage owner. In addition to the changes of coworking and technological advancements, employees are now more focused on healthy work lifestyles. Millennial employees constituted 35% of the workforce in 2017, which means there is roughly one Millennial out of every three employees. They are technologically, environmentally and health conscious. Many of the future office market changes will reflect Millennial values. Office properties are trending to be more flexible, with options for tenants such as: pet-friendly office buildings, garden areas and indoor/outdoor working centers, onsite fitness centers, convenient bicycle racks, fresh markets onsite, and chef-inspired fast casual dining options nearby, to name a few. Many of these amenities may eventually be created within the aforementioned converted garage space, thereby repurposing office building garages. Office space throughout the U.S. is evolving to include coworking space options, enhanced technology leading to the development of excess garage space into mixed-use possibilities and health-geared office buildings. While some conversions are currently happening, others may be trends which will eventually reach the Columbia market and change the nature of Columbia office buildings. Market Conditions The competitive Columbia office market has 16.19 million square feet within eight submarkets. Currently, 30,000 square feet of suburban office space is under construction. The overall quarterly market absorption was 137,511 square feet during the third quarter of 2018. The majority of absorption was within the central business district; 66,510 square feet was located within three buildings: the First Base Building; 1600 Williams Street and 1732-1734 Main Street. The Columbia market vacancy rate dropped considerably during the third quarter to 10.86%, down 86 basis points from last quarter and 12.06% lower than it was one year ago. The overall average market full-service rental was $15.97 per square foot during the third quarter of 2018, which is 2.50% lower than the second quarter of 2018 and may be due to the lower quality of the remaining available space. down from 10.12% during the second quarter to 9.54% this quarter due to 38,264 square feet of Class A office space absorption. The overall CBD submarket absorbed an astounding 102,695 square feet of office space this quarter. The average weighted rental rate rose from $20.49 per square foot during the second quarter of this year to $20.52 per square foot this quarter. However, Class A weighted rental rates dropped slightly from $22.32 per square foot during the second quarter of 2018 to $22.04 per square foot during the third quarter of 2018. Because rental rates are weighted based on the available remaining space, unless high quality space becomes available, the rental rates will likely continue to be lower in the coming quarters. Suburban The Columbia suburban market consists of 225 buildings totaling 10.49 million square feet, and there is currently a 30,000-squarefoot office building under construction in the Cayce/West Columbia submarket. The suburban submarket vacancy rate fell from 11.92% during the second quarter of 2018 to 11.58% during the third quarter, and the overall market absorption was 35,947 square feet. Class A office buildings within the suburban submarkets posted an absorption of 38,252 square feet this quarter, and the vacancy rate dropped to 6.55% during the third quarter from 8.48% last quarter. The average weighted rental rates within the suburban submarkets averaged $14.75 per square foot, and Class A suburban rental rates rose from $19.03 per square foot last quarter to $19.27 per square foot this quarter for the remaining available suburban office space. 1122 Lady Street Columbia, SC Columbia Business District (CBD) The Columbia Central Business District has 97 buildings totaling 5.69 million square feet within the market. The vacancy rate within the CBD dropped from 11.34% during the second quarter of 2018 to 9.54% this quarter; likewise, Class A vacancy is also lower, Source: Colliers International 2 South Carolina Research & Forecast Report Q3 2018 Columbia Office Colliers International

The new standard includes: all office buildings 10,000 square feet or larger, except medical office and government-owned buildings; all single tenant office buildings; buildings in an expanded geography; data for all quarters beginning in Q4 2008; and excluding office condominiums. In addition, the submarkets are separated by class levels A, B and C (A being the highest quality space and C being of lesser quality), and are also divided into 2 divisions: Central Business District (CBD) and Suburban. The Central Business District submarket consists of a highly-populated business area with infrastructure and an office building/high-rise environment, which is often accompanied by heavy daytime foot traffic. A Suburban submarket is an area or town existing as a mixed-use community within commuting distance of a larger city. Due to the adjustments of the building inventory, comparison of data included in previously published market reports should be avoided. 3 South Carolina Research & Forecast Report Q3 2018 Columbia Office Colliers International

Market Forecast The Columbia office market remains tight, with few quality spaces available to lease; this will cause the weighted market rental rate average to decline until the remaining spaces are updated or upgraded space becomes available. In addition to general suite upgrades, Columbia will begin to see office building transformations, which are beginning to occur in primary markets throughout the U.S. In order to keep up with coworking trends and technological advancements, parking garage space may eventually be developed into a mixed-use areas if the driverless car trend becomes an everyday reality. Also, office buildings will be geared toward healthy initiatives by creating more outdoor work spaces, pet-friendly environments, fast casual eating options, coffee shops or juice bars, onsite shopping, and flexible building access to accommodate the varying work schedules of Millennial employees. With no significant new construction planned for the Columbia office market and owners hesitant to build due to the rise of construction costs, the conversion of remaining building areas may be the newest trend to look for within Columbia office buildings.
