ROUTE 128 & INTERSTATE 495 SUBURBAN OFFICE MARKET REPORT

ROUTE 128 & INTERSTATE 495 SUBURBAN OFFICE MARKET REPORT FIRST QUARTER 2018

STRONG MOMENTUM TO START NEW YEAR Greater Boston s suburban office market encompasses over 107 million square feet and consists of eight major submarkets concentrated along Route 128 and Interstate 495. Immense pressure across the Boston and Cambridge markets has caused tenants to consider suburban locations for rent relief and future growth opportunities, however not all suburban locations are created equally. Today s tenants demand the Downtown amenity package which includes fitness centers & locker rooms, on-site conference & dining facilities as well as surrounding mixed-use vibrancy including food & beverage, entertainment and housing. As Greater Boston s premier suburban market, the Route 128 loop has garnered global recognition for its proximity to urban markets, excellent infrastructure, distinguished tenant base and top quality assets. During the first quarter, leasing velocity maintained its momentum from last quarter with 313,650 square feet of quarterly net absorption which lowered the vacancy rate to 9.7%. Interstate 495, the outer suburban belt, has traditionally served as the back office and corporate campus solution. However, as the eastern Massachusetts landscape has evolved and become more saturated, tenants are looking to I-495 locations for larger blocks of space as well as more economical solutions across all business sectors. Despite a slow first quarter, I-495 s 12-month absorption eclipsed 501,850 square feet which translates into a 15.0% vacancy rate. Looking forward, strong regional macroeconomic indicators coupled with strengthening regional demographics have the Greater Boston suburban real estate market positioned for future growth. Over the next 12 months, watch as both investors and tenants acknowledge the growing spread between Downtown pricing and the suburbs and the market adjusts accordingly. 3.5% 4.1% # 3.3% 2ND FEBRUARY MASSACHUSETTS UNEMPLOYMENT FEBRUARY NATIONAL UNEMPLOYMENT MA QUARTERLY GDP GROWTH HIGHEST GDP PER CAPITA NATIONALLY

CLASS A & B OFFICE ROUTE 128

The Route 128 market began the new year on a positive note with strong leasing velocity leading to 313,650 square feet of net absorption. Vacancy dropped to 9.7% which supported asking rate growth and brought the average asking rate into the high $20 s PSF. Generally speaking, the best performing assets cater to modern tenants including: contemporary lobbies & common areas, fitness & dining services and outdoor spaces in addition to upgraded building mechanicals and infrastructure. With great access to the MBTA Orange Line, but often not perceived as a strong office market, Medford recorded two of this quarter s larger leases. Agero, the innovative automobile experience provider, grew within the market announcing a major relocation from One Cabot to a 115,000 square foot build-to-suit at 400 Rivers Edge. Offsetting the vacating Agero was iheartradio who disclosed they will nearly double to 21,500 sqaure feet at One Cabot. To the west of the city, Boston Properties landed Simpson Gumpertz & Herger s 100,000 square foot requirement at the under construction 20 City Point in Waltham. After extensively touring the market and narrowly missing out on space at Boston Landing, SGH committed to the premier Waltham property. Joining SGH in a relocation to Waltham will be Kendall Square based Visterra who has leased 27,000 square feet at Alexandria s 275 Second Avenue which will undergo an office to lab conversion this year. The southern Route 128 market continued gaining ground, however the pace of asking rate growth has not kept up with the west and north markets. At 500 River Ridge in Norwood, Corbus Pharmaceuticals leased 32,000 square feet. The investment sales market came to life this quarter with several notable transactions. Spear Street continued its local buying spree by acquiring the former Reebok HQ in Canton for $88 million or $130 PSF. It remains to be seen whether the they have a tenant in tow or will undertake a large scale multi-tenant lease up strategy. Just around the corner, AEW picked up the newly renovated 101 Station Drive in Westwood for just north of $250 PSF. In Waltham, Jumbo Capital scooped up Stony Brook Office park for just under $300 PSF. $ 9.7% DIRECT VACANCY # 2.6% SUBLEASE AVAILABILITY # 15.4% TOTAL AVAILABILITY # 572,050 SF 12-MONTH ABSORPTION # $27.98/SF AVERAGE ASKING RATE

CLASS A & B OFFICE INTERSTATE 495

Quarterly performances were mixed across I-495 s submarkets with the net result leading to just over 72,550 square feet of negative quarterly absorption. However, over the past 12 months, the market achieved nearly 501,850 square feet of positive absorption which brought the vacancy rate to 15.0%. Generally speaking, I-495 offers less volatility than its more urban counterparts by historically maintaining a 12-18% vacancy rate with average rents in the high teens to mid $20 s for well positioned product. Several leases were signed in the Mass Pike submarket. At 35 Parkwood Drive, a formerly vacant EMC building, ownership has nearly completed their leasing campaign after signing Spring Bank Pharmaceuticals to a 29,850 square foot lease. In Westborough, the Pall Corporation leased 22,800 square feet at 1700 West Park Drive. While in Framingham, Boston Heart Diagnostics committed to 11,000 square feet at 175 Crossing Boulevard. The Route 3 North corridor, which houses some of I-495 s premier technology & defense tenants, recorded strong quarterly activity in Chelmsford. At 300 Apollo Drive, HCL America and US Alliance signed 29,050 and 20,000 square foot leases respectively. In the Northeast submarket, Andover posted strong leasing momentum with Aras Corporation nearly doubling their size to 66,300 square feet during a relocation within Andover Landing into 100 Brickstone Square. At 6 Riverside Drive, Physical Sciences Inc took 33,000 square feet in an expansion aimed to grow its tactical robotics division. The forecast for the Interstate 495 market remains bright particularly as interior suburban locations become more congested and expensive. Across the board, tenants are more real estate conscience than ever before and face the challenge of keeping costs in check while cultivating corporate culture that retains and attracts top talent. # 15.0% DIRECT VACANCY $ 1.8% SUBLEASE AVAILABILITY 20.2% TOTAL AVAILABILITY $ 501,900 SF 12-MONTH ABSORPTION # $20.66/SF AVERAGE ASKING RATE
