CUSTOMERS: ORGANIC GROWTH Highlights Customers Growth with DFT Once landed, our customers tend to stay with us and take on more leases 75% of our leased space represents expansions from existing customers (who have been with DFT for more than 1 year) Organic growth is testament to the reliability of our services, value of our product resulting in +180 MW of organic growth 75% One Lease 25% Multiple Leases Customers continue to grow with us 19 November 10, 2015

CURRENT LOCATIONS Elk Grove Village, IL (2 data centers) 43.8 MW Piscataway, NJ 18.2 MW Santa Clara, CA 36.6 MW Northern Virginia (8 data centers) 158.6 MW 20 November 10, 2015 12 data centers in 4 markets: 257.2 MW

HISTORIC LEASING TRENDS DFT s Historic Leasing (Annually) Current Development Capacity (1) Northern Virginia 12-18 MW 5 years Chicago 10-12 MW 5 years Silicon Valley 8-10 MW 2 years Northern New Jersey 1-2 MW -- Once Silicon Valley is out of capacity, DFT can only add about 25 MW of capacity annually, which is less than 10% capacity growth (1) Includes land under contract Result is less than 10% growth for revenue, EBITDA and FFO per share 21 November 10, 2015

CURRENT PRODUCT OVERVIEW DFT provides wholesale products Limited power density flexibility No flexibility for resiliency level Lease structure is 100% Triple Net Allows for full recovery of operating expenses Requires educating customers on the Triple Net structure Impacts new customer acquisition Slower pace of new customer acquisition 22 November 10, 2015

SITUATION ANALYSIS SUMMARY Development of existing geographies using current product yields $690 million of revenue in 2020 Revenue growth at 8% CAGR (2016-2020) Rate of growth is slower when compared to peers Must grow faster while improving profitability Must diversify customer base with high quality new logos to reduce impact of customer departure and risk of rent roll downs 23 November 10, 2015 Key challenges: accelerating growth and diversifying customers

WHOLESALE OPPORTUNITIES Multi-tenant wholesale data center market is growing In aggregate, projected demand outstrips supply, even as some geographies risk potential oversupply Growth of the Internet continues to fuel demand Rise of cloud and data storage Outsourcing increasingly attractive as it lowers total cost of ownership Prospective wholesale customer needs continue to evolve Changes in technology affect how data is managed, accessed, stored, and delivered Smaller customers continue to move data to cloud Requires innovation in design and operations to decrease costs while increasing flexibility Unmet demand and evolving customer needs create wholesale opportunities 25 November 10, 2015

Rtl. New markets provide vertical opportunities of interest 63 November 10, 2015

64 November 10, 2015 STRATEGIC PRIORITIES: NEW PRODUCTS

FINDINGS: Customers, Products & Services Prospective customers in our target markets are buying a range of density and reliability Analysis of existing and proposed data centers show range of N, N+1, N+2, 2N facilities Helpful to segment customers based on their requirements for resilience and reliability Allows us to tailor our products and services, and target marketing and sales approach more effectively Multi-tenant data center is viable in new markets and geographies Growing demand for multi-tenant data centers Desire from both prospective and current customers to diversify their locations in addition to adding capacity Requires different data center designs to suit specific market conditions Understanding of customers needs is critical to properly align products and services Multiple insights from customer analysis 65 November 10, 2015

FINDINGS: Customers, Products & Services New product and service offerings enhance existing products and help attract new customers Varied customer requirements suggest need for flexibility and adaptability in our product and ways of working Widening gap between low and high density customers Hyper-scale segment may have lower resiliency requirements as new layer of redundancy is achieved via multiple data centers in diverse geographies Desire to add computing power more rapidly favors shorter time to build rooms Resiliency levels range from N to 2N with greatest concentration at N+1 Capital and operating cost remain important to both DFT and our customers Smaller initial deployments to lower up front capital costs Preference for fixed operating costs among some customer groups Choice of product also impacts our operating and lease models Manage customer and DFT risk Assure appropriate pricing Multiple products are viable in the market 66 November 10, 2015

NEW PRODUCTS: Data Center Flexibility Support a range of power densities (100-300 watts per SF) Support a range of resiliencies (N to 2N) Agility Create shell and backbone infrastructure that can support rapid deployment of customized solutions for end users Avoids stranded UPS/Cooling capacity in low density/low resiliency configurations Future Proof Allow customers to expand in the same room as technologies evolve and power density needs increase Easily reconfigurable when lease expires and tenant occupancy changes New product adds flexibility and agility for now and later 67 November 10, 2015

NEW PRODUCTS: Data Center Features Approximately 150,000 square foot powered shell, expandable in roughly the same increment depending on lot size Shell is built with incoming utility, expandable generator plant and backbone to feed UPS systems UPS Systems may be static or rotary technology Each shell has eight (8) 10,000 square foot computer rooms Cooling solution is deployable separately and custom configured for the climate Product features allow varied deployment approach to suit the market 68 November 10, 2015

RAPID DEPLOYMENT Determine a customer s specific density and resiliency needs Optimize time to deliver customized solution Target 16-20 week build cycle Compared to 6 to 9 months to build out a phase in our current model Requires key elements to be in place Pre-engineered design solutions Inventory of component to reduce lead time Standing agreements with contractors and suppliers Rapid deployment speeds product delivery to customers 72 November 10, 2015

NEW PRODUCTS: Flexible Lease Structure Full Service lease structure is an important alternative to offer customers, particularly new customers Simplicity - the Triple Net structure is less widely understood Certainty - some customers want to be able to budget costs throughout the lease term with greater certainty than the Triple Net model allows Rent includes all costs related to operating expenses Full rent amount subject to annual escalation Exceptions: Metered Power including cooling uplift - passed through to customer at DFT cost Property taxes and insurance increased above annual escalation percentage passed through to customer Amortized capital costs that result from change in law (e.g., environmental regulation requires additional scrubbers or ADA requires additional accommodations) DFT will price full service leases so that it can recover its operating costs over the lease term and earn a risk premium New lease structure attracts new customers 73 November 10, 2015
