MPX current ownership structure

19. 1. E.ON acquires 24.5% stake from Eike Batista for a
price of R$10/share
■ Price adjusted to max R$11/share, depending on
settlement price of capital increase and MPX share
performance in subsequent 6 months
2. MPX carries out min R$1.2bn public primary offering
■ E.ON committed to subscribe for R$0.4bn at R$10/share
■ BTG retained as global bookrunner with firm underwriting
commitment at R$10/share for balance not subscribed by
E.ON and other investors
3. MPX-E.ON JV reintegrated into MPX at book value
Expected outcome after Step 3:
■ E.ON achieves ~36% direct share in MPX
■ Eike Batista reduces interest in MPX to ~24%
■ MPX financial position is strengthened to fund forthcoming
investments

Indicative evolution of MPX shareholding structure

21. Stronger capital structure and enhanced execution capabilities
21
Transaction rationale
Simplification of operating and governance structures
■ MPX becomes E.ON’s main vehicle for expansion in Brazil, instead of JV with MPX
■ E.ON and Eike Batista shall execute a shareholders’ agreement to regulate the exercise of their voting rights
Strengthening of MPX capital structure to support development pipeline
■ Strong energy demand growth expected in coming years
■ Structural need for thermal capacity to back-up hydro -> dedicated thermal auctions under discussion
■ Robust pipeline of licensed greenfield thermo generation projects and strong origination capabilities
■ Superior access to fuel resources
Enhanced execution capabilities
■ Stronger influence of E.ON in management of MPX, enhancing execution capabilities
■ E.ON’s proven expertise in construction & operation of power plants to contribute to robust process improvements at MPX

22. Robust pipeline of thermal projects to meet
Brazil’s need for a more reliable electric system
Tax-advantaged thermal power plants coming
on-line
Attractive monetization of natural gas resources
E.ON to join control group further supporting
development of strong portfolio of energy assets
Experienced management team to execute on
strategic vision
Stronger capital structure and enhanced execution capabilities to develop
robust pipeline of licensed greenfield thermo generation projects
Deficit in the demand-supply balance
Energy matrix concentrated in hydropower
Stagnated storage capacity
Reservoirs at levels similar to those of 2001’s
energy rationing
Spot prices (PLD) at historical highs for the last 10
years
Need to increase the base generation capacity
OPPORTUNITIES
INVESTMENT
HIGHLIGHTS
