c) The application for renewal must be accompanied by a plan containing an indication of the Exploration Perimeter that was kept as well as a report specifying the works carried out since the Effective Date on the relinquished surfaces and the results obtained.

3.9 The Contractor may at any time, upon three (3) months’ notice, notify the Minister that he is surrendering all or a portion of the Exploration Perimeter. In the event of a full surrender, the Exploration Authorization shall terminate automatically on the date of said notification. In the case of a partial surrender, the provisions of Article 3.8 here above shall be applicable.

In all cases, no voluntary surrender during the course of an exploration phase shall reduce the exploration work commitments stipulated in Article 4 here below for said phase, nor does it terminate the corresponding bank guarantee.

exploration period and of twenty-two million Dollars ($22,000,000) for the third Phase of the exploration period.

If on expiration of any phase of the exploration period or in the case of total or partial surrender or termination of the Contract, the exploration works have not reached the minimum commitments of this Article 4, the Minister shall have the right to call the guarantee for an amount equal to the amount of the guarantee after deduction of the estimated cost of the minimum work actually carried out.

Such cost shall be calculated on a lump-sum basis in utilizing the following unit costs:

a) three thousand five hundred Dollars ($3500) per square kilometer;

b) twenty-two million Dollars ($22,000,000) per exploration well.

Once the payment is made, the Contractor shall be deemed to have fulfilled his minimum exploration work obligations per Article 4 of this Contract; the Contractor may, except in the event of cancellation of the Exploration Authorization for a major failure in performance of this Contract, continue to benefit from the provisions of said Contract and, in the case of an acceptable application, obtain the renewal of the Exploration Authorization.

ARTICLE 9 : APPRAISAL OF A DISCOVERY AND GRANTING OF AN EXPLOITATION AUTHORIZATION

9.1 If the Contractor discovers Hydrocarbons in the Exploration Perimeter, he must so notify the Minister in writing the soonest possible and carry out, pursuant to good oilfield practice in the international petroleum industry, the necessary tests. Within the thirty (30) days following the provisional closure or abandonment of the discovery well, the Contractor must submit to the Minister a report giving all information pertaining to such discovery and formulating recommendations of the Contractor as to whether or not to pursue his appraisal.

9.2 If the Contractor wishes to undertake the appraisal works of the above-cited discovery, he must diligently submit to the Minister for approval the appraisal work program, the timetable for execution and the estimate of the corresponding budget, not later than six (6) months following the date of the notification of the discovery referred to in Article 9.1 here above.

The Contractor must then commence with maximum diligence the appraisal work pursuant to the program drawn up, it being understood that the provisions of Articles 5.2 and 5.3 here above shall apply to said program.

9.3 Within the three (3) months following the completion of the appraisal works, and not later than thirty (30) days prior to the expiration of the third phase of the exploration period defined in Article 3.2, as may be extended pursuant to the provisions of Articles 3.3 and 3.4 here above, the Contractor shall submit to the Minister a detailed report giving all the technical and economic information relative to the deposit so discovered and appraised, and establishing the commercial character or not of the said discovery. Such report shall in particular include the following information: the geological and petrophysical, characteristics, and the estimated delimitation of the deposit; the results of the production tests carried out, the nature, properties and volume of Hydrocarbons which it contains, a preliminary technical and economic study on the placement of the deposit into production.

9.4 Any quantity of Hydrocarbons produced from a discovery before the discovery has been declared commercial, if it is not utilized for the carrying-out of the Petroleum Operations, or

lost, shall be subject to the provisions of Article 10 of this Contract.

9.5 A deposit considered by the Contractor to be commercially exploitable gives him the right to an Exploitation Authorization. In such case, the Contractor shall submit to the Minister, within the three (3) months following the submission of the report referred to in Article 9.3 here above, and not later than thirty (30) days prior to the expiration of the third phase of the exploration period defined in Article 3.2, possibly extended pursuant to the provisions of Articles 3.3 and 3.4 here above, an application for an Exploitation Authorization. Said application shall specify the lateral and stratigraphic delimitation of the Exploitation Perimeter, which shall cover only the presumed limits of the deposit discovered and appraised in the Exploration Perimeter then currently valid and shall be accompanied by technical justifications necessary for said delimitation. The above-cited application for an Exploitation Authorization shall be accompanied by a detailed development and production program, including in particular for the deposit in question :

a) An estimate of the recoverable reserves, proven and probable and of the corresponding production profile, as well as a study of the methods of recovery of hydrocarbons and development of natural gas;

b) A description of the works and facilities required to put the field into production, such as number of wells, facilities required for production, separation, processing, storage and transport of Hydrocarbons;

c) A program and a schedule for carrying out the said works and facilities, including startup date for production ;

d) An estimate of development investments and exploitation costs itemized for each year as well as an economic study confirming the commercial character of the deposit ;

f) An environmental impact study of the development project, carried out by the Contractor pursuant to the provisions of the Environmental Code.

g) An outline of a Rehabilitation Plan to return the sites to their original condition at the end of exploitation.

The Minister may propose revisions or modifications to the development and production program referred to above, as well as to the Exploitation Perimeter applied for, in notifying the Contractor thereof with all justifying supporting data deemed appropriate, within the ninety (90)

days following receipt of the said program. The provisions of Article 5.2 here above shall apply to said program with regard to its adoption.

When the results acquired during the course of development justify changes to the development and production program, said program may be modified in utilizing the same procedure as that referred to here above for its initial adoption.

9.6 The Exploitation Authorization shall be granted by the Minister within forty-five (45) days following the date of adoption by the Parties of the development and production program. The granting of an Exploitation Authorization entails ipso facto the cancellation of the Exploration Authorization inside of the Exploitation Perimeter; however, the Exploration Authorization continues to be valid outside that perimeter until its expiration date, without the minimum exploration work obligation referred to in Article 4 above for the subject phase of the exploration period being modified.

9.7 If the Contractor makes several commercial discoveries within the Exploration Perimeter, each of such will give rise, in accordance with Articles 9.5 and 9.6 here above, to a separate Exploitation Authorization corresponding to an Exploitation Perimeter.

9.8 If in the course of work subsequent to the grant of an Exploitation Authorization, it appears that the deposit has an extension greater than that initially provided for in Article 9.5 here above, the Minister shall grant to the Contractor, within the framework of the Exploitation Authorization already granted, the additional portion, provided that the extension is an integral part of the currently valid Exploration Perimeter and that the Contractor supplies the technical justifications for the extension applied for.

If it appears that the deposit has an extension less than that initially provided for, the Minister may require the Contractor to relinquish the exterior portion(s) of the boundaries of the deposit.

9.9 In the event that a deposit extends beyond the boundaries of the currently valid Exploration Perimeter, the Minister may require the Contractor to exploit such deposit together with the holder of the adjacent perimeter following the provisions of Article 53 of the Crude Hydrocarbons Code. Within the twelve (12) months following the written request of the Minister, the Contractor must submit to him, for approval, a draft development and production program of the relevant deposit drawn up in agreement with the holder of the adjacent perimeter.

In the case where the deposit extends over one or more other perimeters which are not under contract, the process of extension of the contractual perimeter may be undertaken, pursuant to the provisions of the Crude Hydrocarbons Code.

9.10 The Contractor must start up the development operations including the necessary studies, not later than six (6) months following the date of granting of the Exploitation Authorization referred to in Article 9.6 here above and must pursue them with the maximum diligence. The Contractor undertakes to carry out the development and production operations according to good oilfield practice in the international petroleum industry, making it possible to ensure the optimum recovery of Hydrocarbons contained in the deposit. The Contractor undertakes to proceed as soon as possible with studies of assisted recovery in consultation with the Ministry and to utilize such processes if, in the estimation of Contractor, such processes will lead under the economic conditions to an improvement of the rate of recovery.

9.11 The duration of the exploitation period during which the Contractor is authorized to ensure the production of a deposit declared to be commercial is set at twenty-five (25) years if the exploitation is for deposits of Crude Petroleum and thirty (30) years if the exploitation is for deposits of Dry Gas, starting from the date of granting of the corresponding Exploitation Authorization.

Upon the expiration of the initial period of exploitation defined here above, the Exploitation Authorization may be renewed for an additional maximum period of ten (10) years upon an application by Contractor providing supporting information submitted to the Minister at least one (1) year prior to said expiration, provided that the Contractor has fulfilled all his contractual obligations during the initial exploitation period and that he proves that additional commercial production from the Exploitation Perimeter remains possible during the additional period applied for.

9.12 For any deposit having given rise to the granting of an Exploitation Authorization, the Contractor must, without prejudice to the provisions of Article 21 here below, carry out at his own expense all appropriate and necessary Petroleum Operations to place the deposit into exploitation, in conformity with the adopted development and production program.

However if the Contractor believes, on the basis of technical knowledge acquired on such deposit, and can make the accounting proof during the course of the development and production program or during the course of exploitation that producing from such deposit cannot be, or can no longer be, commercially profitable, even though the discovery well and the appraisal works have led to the granting of an Exploitation Authorization pursuant to this Contract, the Minister undertakes to not obligate the Contractor to pursue the works and to

explore with the Contractor, to the extent possible, technical and economic improvements which would permit the Contractor to consider the profitable exploitation of said deposit. In the case where the Contractor decides not to pursue the exploitation works and if the Minister asks him to, the Contractor shall surrender the relevant Exploitation Authorization and the rights which are attached thereto.

9.13 The Contractor may at any time, subject to so notifying the Minister in writing with an advance notice of at least six (6) months, surrender totally or in part an Exploitation Authorization, provided that he has satisfied all obligations provided for in this Contract.

9.14 The Contractor undertakes for the duration of the Exploitation Authorizations to produce annually quantities of Hydrocarbons from each deposit according to generally accepted norms in the international petroleum industry in taking principally into consideration the rules for the proper conservation of deposits and the optimal recovery of the reserves of Hydrocarbons under economic conditions for the duration of the relevant Exploitation Authorizations.

9.15 The ceasing of production of a deposit for a duration greater than six (6) consecutive months, decided upon by the Contractor without the consent of the Minister, may lead to the cancellation of this Contract within the terms set forth in Article 25 here below.

9.16 The Minister may place the Contractor on notice by registered letter with return receipt to remedy the following shortcomings within a time period of three (3) months, if the latter, without duly justified reasons:

a) Has not submitted an appraisal work program for said discovery within the time period referred in Article 9.2 here above ;

b) Has not carried out the appraisal works of said discovery in conformity with the appraisal program referred to in Article 9.2 here above ;

c) Or has not submitted an application for an Exploitation Authorization within the time period referred to in Article 9.5 here above.

If the Contractor has not remedied the above shortcomings within the mentioned time period, the Minister may then demand that he relinquish immediately and without compensation all his rights within the presumed boundaries of said discovery, including the Hydrocarbons which could be produced from it.

The State may then carry out all works of appraisal, development and production of such discovery upon condition however that it does not cause damage to the performance of the

Petroleum Operations of the Contractor in the Exploration Perimeter or any Exploitation Perimeter governed by the Contract.

ARTICLE 10 : RECOVERY OF PETROLEUM COSTS AND PRODUCTION SHARING

10.1 From the commencement of regular Hydrocarbons production carried out pursuant to an Exploitation Authorization or an early production authorization, that production shall be shared and sold in accordance with the provisions hereafter.

10.2 For the recovery of Petroleum Costs, the Contractor shall freely retain each Quarter, and for each Exploitation Authorization, a share of total production equal to fifty-five percent (55%) for Crude Petroleum and sixty-two percent (62%) for Dry Gas, calculated on total production which is not utilized for Petroleum Operations, nor wasted, or, if applicable, a lower percentage of production, or only a lower percentage which would be necessary and would suffice.

The value of the share of total production allocated for the petroleum cost recovery of the Contractor as defined in the preceding subparagraph, shall be calculated in accordance with the provisions of Articles 14 and 15 here below.

In the course of a Calendar Year, should the Petroleum Costs not yet recovered by the Contractor pursuant to the provisions of this Article 10.2 exceed the equivalent in value of fifty-five percent (55%) with respect to Crude Petroleum and sixty-two percent (62%) with respect to Dry Gas, of the total production calculated as indicated here above, the excess which cannot be recovered for the Calendar Year under consideration shall be carried forward to the following Calendar Year(s) until full recovery of Petroleum Costs or the termination of this Contract. The recovery of Petroleum Costs for any Quarter shall be scheduled in the order stipulated in the Accounting Procedure.

10.3 The volume of Hydrocarbons, related to each Exploitation Authorization, which remains for each Quarter after the Contractor has taken from total production the share necessary to the recovery of Petroleum Costs under the provisions of Article 10.2 here above, shall be shared between the State and the Contractor in the following manner, in the ratio of the applicable figure for the ratio “R” defined as follows:

Value of « R »	Share of the State		Share of the Contractor
Less than 1	31	%	69	%
Greater than or equal to 1 and less than 1.5	33	%	67	%
Greater than or equal to 1.5 and less than 2	35	%	65	%
Greater than or equal to 2 and less than 2.5	37	%	63	%
Greater than or equal to 2.5 and less than 3	39	%	61	%
Greater than or equal to 3	42	%	58	%

For the application of this Article, the ratio « R » means to the ratio of « Cumulative Net Revenue » of Contractor over « Cumulative Investments » in the relevant Exploitation Perimeter, where:

« Cumulative Net Revenue » means the sum, calculated from the Effective Date until the end of the preceding Quarter, of the value of Hydrocarbons obtained by Contractor pursuant to the provisions of Articles 10.2 and 10.3 here above ; less the Exploitation Petroleum Costs incurred by the Contractor, as such are defined and determined under the provisions of the Accounting Procedure.

« Cumulative Investments » means the sum, from the Effective Date up until the end of the preceding Quarter, of the Exploration Petroleum Costs and the Development Petroleum Costs incurred by the Contractor as defined and determined under the provisions of the Accounting Procedure.

10.4 The State may receive its share of production defined in Article 10.3 here above, either in kind, or in cash.

10.5 If the State wishes to receive in kind all of part of its share of production defined in Article 10.3 here above, the Minister shall advise the Contractor in writing not less than ninety (90) days prior to the commencement of the relevant Quarter and specify the exact quantity it wishes to receive in kind during said Quarter and the modalities of delivery, which must be specified in the lifting contract.

For this purpose, it is agreed that the Contractor shall not commit to the sale of a part of the State production, for a term which exceeds one hundred and eighty (180) days, unless he shall have obtained the written consent of the Minister.

10.6 If the State wishes to receive in cash all or part of its share of production specified in Article 10.3 here above, or if the Minister has failed to notify the Contractor of its decision to take a portion of the State’s production in kind in accordance with Article 10.5 here above, the Contractor is obligated to sell the State share of production which the State wishes to take in cash during the relevant Quarter, and to proceed with the liftings of such share in the course of such Quarter, and to pay the State within thirty (30) days following each lifting, an amount equal to the quantity corresponding to the portion of the State production share, multiplied by the sale price F.O.B., after deduction of the costs attributable to such sales.

The Minister shall be entitled to request the settling of the sales of the State share of production effected by the Contractor either in Dollars or in any other convertible currency in which the transaction took place.

ARTICLE 14 : PRICE AND MEASUREMENT OF HYDROCARBONS

14.1 The unitary market price of the Crude Petroleum used in consideration for purposes of Articles 10 and 11 here above shall be the “Market Price” F.O.B. the Delivery Point, expressed in Dollars per Barrel, as determined here below for each Quarter.

A Market Price shall be established for each type of Crude Petroleum or blend of Crude Petroleums.

14.2 The Market Price applicable to Crude Petroleum lifted in the course of a Quarter shall be calculated at the end of each Quarter under consideration, and shall be equal to the weighted average of prevailing prices obtained by the Contractor and the State in the course of their sale of Crude Petroleum to Third Parties in the course of the Quarter under consideration, adjusted as appropriate to reflect differentials in quality and density, and on the terms of F.O.B. delivery and payment terms provided the quantity sold in such manner to Third Parties in the course of the Quarter under consideration corresponds to no less than thirty percent (30%) of the total of the volumes of Crude Petroleum extracted from the Exploitation Perimeters existing under this Contract, taken as a whole, and sold in the course of the said Quarter.

14.3 If such Third Party sales do not take place during the Quarter under consideration, or if they constitute less than thirty percent of the total of the quantities of Crude Petroleum of the Exploitation Perimeter granted under the present Contract taken as a whole and sold in the course of the said Quarter, the Market Price shall be arrived at by comparison with the « Current International Market Price » for the Quarter under consideration of the qualities of Crude Petroleum produced in Mauritania and in neighboring producing countries, taking into account differentials of quality, density, transport and terms of payment.

« Current International Market Price » shall be a reference price based on Dated Brent prices, as such are published in “Platt’s Crude Oil Marketwire” or similar internationally recognized

publication, averaged for the month(s) during which sales were made and adjusted for differences in quality, API gravity, terms of FOB delivery and payment terms. If Dated Brent is replaced by another internationally recognized reference crude, the published quotes of the replacement crude shall be used instead.

14.4 In particular the following transactions are not taken into account in calculating the Market Price of the Crude Petroleum:

a) Sales in which the buyer is an Affiliated Company of the seller as well as sales between entities making up the Contractor;

b) Sales which include some consideration other than payment in freely-convertible currency or sales attributable in whole or in part to motivations other than the usual economic incentives attached to sales of Crude Petroleum on the international market (such as barter contracts, sales from government to government or to governmental units).

14.5 A committee presided over by the Minister or his delegate and including other representatives of the State and those of the Contractor shall meet at the request of its president, at the end of each Quarter, to establish, according to the stipulations of this Article 14, the Market Price of the Crude Petroleum produced, applicable to the Quarter elapsed.

ARTICLE 1: GENERAL PROVISIONS

1.1 Purpose

The purpose of this Accounting Procedure is to set the rules and methods of accounting for the verification of Petroleum Costs to provide for their recovery and for the purpose of sharing production in accordance with Article 10 of the Contract, as well as the rules to determine net profits of the Contractor for purposes of calculating the tax on industrial and commercial profits.

1.2 Statements

The accounts, books and registers of the Contractor shall be maintained consistent with the rules of the applicable accounting plan in Mauritania and the practices and methods in use in the international petroleum industry.

Pursuant to the provisions of Article 20.2 of the Contract, the accounts, books and registers of the Contractor shall be kept in the English language using the Dollar as the unit of account.

Anytime, whenever it is necessary to convert into Dollars expenses and revenue paid or received in any other currency, these currencies shall be valued on the basis of the rate of exchange quoted on the foreign-exchange market of Paris, in accordance with terms determined by mutual agreement.

1.3 Interpretation

The definitions of words which appear in this Appendix 2 are the same as those of the corresponding words as they appear in the Contract.

The word « Contractor », has the meaning given to it by the Contract, and may sometimes refer to the Operator when the Contractor is made up of several entities and when Petroleum Operations are conducted by the Operator on behalf of all these entities, or sometimes the reference is to each of these entities whenever the obligation of each individual entity is being addressed.
