The Parties shall meet periodically, at least monthly, in order to analyze the availability and conditions of energy in the market. The following activities will be carried out at this meeting:

a)	Ecopetrol will present the Ecopetrol Group’s medium- and long-term demand projections and hedging expectations.

b)	The Marketer must submit:

(i)

market monitoring and analysis,

(ii)

the monitoring of supply-demand behavior,

(iii)

the status of compliance with the Expansion Plan,

(iv)

the availability of the Supplier’s own energy, in the event that Ecopetrol has expressed its need to expand its coverage in contracts,

(v)

the projection of short and long-term prices in bilateral contracts and the Energy Exchange,

(vi)

regulatory developments that impact market behavior,

(vii)

evolution and expectations of the behavior of the different tariff components (restrictions, contributions, STN, STR, SDL, among others)

(viii)

evolution and expectations of the behaviour of the CPI and PPI, and

(ix)

those aspects that are considered necessary for a proper understanding of the state of the market.

c)	The Trader shall submit the contractual follow-up referring to the current level of coverage of the Ecopetrol Group’s demand (amount in bilateral contracts vs. amount exposed to component in the stock market).

d)	The Marketer will present hedging alternatives that meet the requirements arising from the previous analyses.

e)	Ecopetrol will evaluate the available energy opportunities presented by the Trader, based on transparent and objective criteria, in order to determine whether it applies to the Target Portfolio as an unregulated user. Based on this analysis, the following procedure will be carried out:

If the opportunities presented by the Trader meet Ecopetrol’s expectations and needs, they will materialize through the acceptance of binding offers, negotiation of bilateral contracts or the mechanism that applies.

ii.

If the opportunities presented by the Marketer partially meet Ecopetrol’s expectations and needs, the latter may accept them and, if necessary, follow the procedure described in paragraph f). In this scenario, Ecopetrol may submit alternative proposals from other suppliers to complement the characteristics of the previously defined requirement.

iii.

If the opportunities presented by the Supplier do not comply or opportunities for review do not arise, Ecopetrol may follow the procedure described in paragraph f) to ensure that its demand for non-regulated energy is met.

f)	By mutual agreement between the Trader and Ecopetrol, an open and competitive process (hereinafter, the “Call”) will be carried out through an independent third party previously approved by Ecopetrol. The Call will be carried out under the following procedure:

Notwithstanding the foregoing, the Marketer may not participate in the Call.

iv.

Each Call for Proposals will be preceded by an analysis of hedging risks, counterparty and others that apply.

The costs derived from the Call will be assumed by Ecopetrol. These costs will be settled and collected by the Trader in the month following the Call, under the terms of the Contract and will be assigned in the invoices of the Borders indicated by Ecopetrol in each Call.

vi.

The independent third party will advance the Call, evaluate the bids and present the results in accordance with the terms provided by Ecopetrol and the Marketer.

vii.

As a result of the above, the independent third party will inform the Marketer and Ecopetrol which was the successful bidder of the Call or will declare it void in the event that the proposed terms are not met.

viii.

Once the successful bidder has been selected, the Marketer will be obliged to contract the energy awarded (with the applicable mechanisms).
