The Share Buyback may be conducted through the Stock Exchange or outside of the Stock Exchange, either gradually or all at once, and shall be completed no later than 12 (twelve) months from the date of the General Meeting of Shareholders (“GMS”) approving the Share Buyback.

Accordingly, this transaction will not affect the Company’s revenue.

As the Share Buyback will be financed using the Company’s internal cash, it will result in a decrease in the Company’s assets and equity of up to Rp4,000,000,000,000.00 (four trillion Rupiah).

MANAGEMENT DISCUSSION AND ANALYSIS REGARDING THE IMPACT OF SHARES BUYBACK ON COMPANY'S BUSINESS ACTIVITIES AND FUTURE GROWTH

The Shares Buyback is expected to have a minimum impact on the cost of the Company’s financing which will reduce the Company's Assets and Equity by the Shares Buyback amount. If the Company uses the entire budget reserved for the Shares Buyback to the maximum amount, the total Assets and Equity will decrease by a maximum of Rp4,000,000,000,000.00 (four trillion Rupiah).

The Company believes that the implementation of the Shares Buyback will not have a material negative impact on the business activities and growth of the Company, because the Company currently has sufficient capital and cash flow to conduct and finance all business activities, business development activities, operational activities and Shares Buyback.

SOURCE OF FUNDS FOR THE SHARES BUYBACK IMPLEMENTATION
