The increase in sales reflect the continued rise in production
from the Gabon fields as well as the first-time consolidation of OMLs 4, 38
and 41 with two liftings carried out in the fourth quarter of 2010.

Change in accounting methods used to treat the share of oil
corresponding to the corporation tax included in profit oil: As from 1
January 2010, the corporation tax paid in kind to the State is recognised in
the Group's financial statements, generating a corresponding increase in
sales (EUR17.8m for 2010). This tax, included in the profit oil paid in kind
to the State, was not previously recognised as such. The data for 2009 and
2008 have been restated as EUR8.6m for 2009 and EUR0.4m for 2008,
respectively.

OTHER

In early 2009, when securing financing for the reserve based
loan, the Group set up hedges of operating cash flows based on oil prices.

In the first half of 2010, 7,500 bopd were hedged at a price
of $60.25/b and in the second half of 2010, 6,750 bopd were hedged at a price
of $60.7/b. Accordingly, the average hedge price for the full year 2010 came
to $60.4/b while the average price of Brent was $79.4/b; this resulted in a
negative adjustment of EUR37.9 million.

In Gabon, the Group received an exclusive development authorisation on 17
December 2010 for the Gwedidi (OMGW) and M'Bigou (OMBG) fields. Maurel & Prom
holds a 100% equity interest in these two fields for which Tulip Oil holds a
15% right of reversion (option exercisable within 120 days); if exercised,
this would reduce Maurel & Prom's interest to 85%.

View of the AEE obtained on the Omoueyi exploration licence

The Group's production in Gabon, which peaked at 20,198 boepd
on 31 December 2010, was impacted in the fourth quarter 2010 by more
extensive maintenance work than expected on the well pumps at the Onal field,
the start of water injection at the Omko field, improvements to surface
installations at the Gwedidi field, and the connection of two wells:
OMOC-N-301 and OMOC-N-302. As a result, production in Gabon averaged 16,981
boepd in the fourth quarter and 14,618 boepd for the full year 2010.

The sanding up of the OMOC-N-301 wells and a set of audit work
performed by TOTAL on the pipeline to Cap Lopez limited current production
which averaged some 17,000 bopd over the month of January 2011.

NIGERIA

In Nigeria, production was progressively integrated during the
second half of 2010.

During this transitional period, a certain number of work
projects were carried out, including in particular the installation of
provisional metering systems. Consequently, the volumes of fluids worked by
SEPLAT are currently under discussion with SPDC to establish a definitive
allocation of production share accruing to SEPLAT. Work is now underway to
install the definitive fiscal meter, which should come into operation in the
first half of 2011.

On a basis of 128 production days in 2010, field production
amounted to 17,632 boepd, or 3,570 boepd in working interest production for
Maurel & Prom.

VENEZUELA

Oil and gas production in Venezuela, after oil taxes in kind
of 30%, came to 993 barrels of oil equivalent per day for the full year 2010.
Oil accounted for 66% of production. This business, consolidated by the
equity method (EAI), is not included in the Group's sales.

GLOSSARY

Gross production: production at 100%.

Working interest production: Gross production - partner's share.

Mining royalties in Gabon: royalties are paid in foreign currencies in
Gabon.

Entitlements: working interest production - in-kind royalties - in-kind
State share of profit oil + corporation tax if the State's profit oil is paid
in kind.

Production sold: entitlements -/+ stock.

Sale price: in Gabon, prices are set by the State based on the oil
quality and benchmark prices. The mutually-agreed costs to achieve
commercial viability are then deducted from these prices.

Sales: entitlements x sale price. Sales are recognised on the production
extraction date.

Taxes and duties: profit oil due to the Gabonese State is paid in foreign
currencies for the Banio field and in kind for the Onal, Omko, Omgw and Ombg
fields. Corporation tax in Gabon is included in the State profit oil and
systematically recognised under sales.

Second-quarter sales: sales for the second quarter are calculated by
deducting sales for the first quarter from the figure for half-year sales.

Third-quarter sales: sales for the third quarter are calculated by
deducting sales for the first half of the year from sales for the first nine
months.

Fourth-quarter sales: sales for the fourth quarter are calculated by
deducting sales for the first nine months of the year from aggregate sales
for full 12 months.

This document may contain forward-looking statements regarding the
financial position, results, business and industrial strategy of Maurel &

to the extent that they are based on events or circumstances that may or may
not happen in the future. These projections are based on assumptions we
believe to be reasonable, but which may prove to be incorrect and which
depend on a number of risk factors such as, fluctuations in crude oil prices,
changes in exchange rates, uncertainties related to the valuation of our oil
reserves, actual rates of oil production and the related costs, operational
problems, political stability, legislative or regulatory reforms, or even
wars, terrorism and sabotage.
