Cienaga, April 27th, 2016

Drummond would like to inform that during this week of collective bargaining negotiations with Sintradrummond, Agretritrenes and Sintramineros, the Company presented a new offer to these union organizations. This offer can be summarized as follows:

• Term of the collective bargaining agreements: 3 years
• Signing bonus: EIGHT MILLION EIGHT HUNDRED THOUSAND PESOS ($8,800,000) subject to the signing of the collective bargaining agreements without a strike
• Wage increase: 1^st year: 6.80%; for the 2^nd: CPI of 2016 + 0.05% and for the 3^rd year: IPC of 2017 + 0.10%.
• Extra-legal bonuses: Remain the same (amount increases as a result of the wage increase)
• All benefits recognized to workers in cash are updated for the 1^st year: 6.77%; for the 2nd and 3rd year they will be increased by the CPI for 2016 and 2017, respectively
• The in-kind benefits to workers remain the same

As you can see, NONE of the benefits for workers will be reduced, much less eliminated, by the Company.

Furthermore, the negotiating committees of the Company and Sintramienergética have agreed to officially initiate collective bargaining on April 26 of this year, therefore 20 days of direct settlement stage will go until May 15, 2016.

The Company reiterates its intention to reach collective bargaining agreements with all of the union organizations, bearing in mind the limitations that the current coal market imposes on the industry.
