Contract Signed Estimated numbers of towers by SCBAM and TAM in 2016

“Leasing telecom towers …enhance the fund’s revenue and dividend to investors…and reduce the fund’s single tenant risk.”

Smith BanomyongCEO of SCBAM

Unit: # of Towers

Source: IPO Offering Circular and DIF’s SET Notification(1) As of Dec 2015, TRUE delivered all of 6,000 towers, as stated in the agreement

“DTAC has agreed to lease an initial amount of 115 slots and expects to lease more slots from DIF next year.”

Khalid ShehzadChief Technology Officer of DTAC

“TAM will focus on signing up more co-tenants for tower assets because …operators …are expanding their networks to fuel growth of their 3G services”

Telecom tower supply landscape

Supply of Telecom Towers

Source: IPO Offering Circular, company filings and public news sources(1) Estimated numbers of BTS slots demand and supply by SCBAM and TAM(2) Estimated numbers of existing towers in Thailand by SCBAM and TAM

DIF is well positioned to capture the demand for BTS slots given its neutrality and

assets that are readily available for rent

Currently the only player who actively markets telco towers to other operators

3,000 towers ready for lease within 2015 and another 3,000 within 2016

Key Drivers for Colocation

Higher frequencies require

more BTS to achieve the

same network coverage

compared to lower

frequencies

Mobile operators want to

rollout networks faster

(driven by the

requirement for 90%

nationwide 3G coverage

within 2015)

Less expensive than

constructing new towers.

Capex savings can

be used for other purposes
