Maurel & Prom - Postponement of General Assembly to June 29, 2011

PARIS, May 5, 2011 - Following a discussion initiated with the Board of Directors
of the Company, it was established that the value of the investment made by
SEPLAT (Nigerian company, Maurel & Prom Nigeria 45%, itself wholly owned by
Maurel & Prom) was not fully reflected in the Group stock price.

Also, to better bring out the value of each major asset of the
Group (Gabon and Nigeria), the Board has therefore decided to study the
distribution to Maurel & Prom shareholders of shares of its Nigerian
subsidiary.

This distribution will lead to a separate listing of this
company and will thus enable each shareholder to appreciate the true value.

An upcoming Board of Directors, to be held no later than May
24, 2011, will specify how to possibly attribute the shares of Maurel & Prom
Nigeria as a special dividend to each Maurel & Prom shareholder , in addition
to the dividend of 0.25 EUR per share originally envisaged.

Accordingly, the Council decided to postpone until Wednesday,
June 29, 2011 at 10 am the holding the General Meeting originally scheduled
May 12, 2011, in order to prepare in the most adapted way the details of the
resolutions to be submitted for approval by the Assembly.

Next dates: 10 May 2011 Q1 2011 Sales (after close of trading)
