PNJ’s ‘Defense: Power of Magic’ leading the free game category, surpassing 160,000 downloads.

Under the Developer Incentive Program for Open API Support Group, both firms will be rewarded with financial incentives of KRW
15 million for creating popular apps that exceed 150,000 downloads. SK Planet will pay out an addition KRW 10 million once the
published game hits the 300,000 download mark and extra KRW 10 million after reaching 500,000 mark, thereby providing
performance-based incentives of up to KRW 35 million in total.

The Open API Support Group, inaugurated in October 2011, is a community of individual developers and small-and
medium-sized IT development firms supported by Open Innovation Center to utilize open APIs of SK Planet’s 11 services
including T Map, T Store Game Center, MelOn, and free-to-play, and has to date released 16 apps. Select development projects
are given access to development infrastructure such as development space, handset for testing purposes, and technical
consulting from API Center.

In addition, SK Planet’s Open Innovation Center will receive applications for the third Open API Support Group until August 15,
with announcements for selected development projects scheduled for August 24. Visit OIC official website (http://oic.tstore.co.kr )

“I’m thrilled to hear the success of these apps developed using SK Planet’s open APIs,” said Kim Young-chul, SK Planet’s
Head of Open Collaboration Promote Center. “Going forward, we will continue to expand our API offerings to smaller
development firms as well as individual developers, and put our best efforts in building an ecosystem that drives shared growth.”
