ARTICLE (1)

PURPOSE AND OBJECTS OF THE COMPANY

1.1

The purpose and objects of the COMPANY will be as follows:

	a)		To undertake land and shallow water seismic data acquisition business in the Countries, for the exploration and/or production of oil, gas, water, minerals and/or other mineral resources, by using exclusively onshore or shallow water vibroseis, explosive, or airgun sources and recording equipment temporally deployed on the earth surface or sea bed (the “Activities”).

			For the avoidance of doubt, “shallow water seismic” is defined as Ocean Bottom Cable (OBC) operations realized close to the shore in shallow water depth and which typically represent an extension of land/transition zone seismic surveys (whether concomitant or not).

	b)		To undertake all geodetic, mapping and survey activities in direct relation with the Activities.

	c)		To undertake import, export, management, maintenance and repair of any and all equipment necessary or useful to the Activities.

	d)		To undertake direct or indirect participation in any business, firm or company whose object would be primarily to promote and conduct the Activities.

	e)		And, generally, to undertake any business, industrial, mining, financial, personal or real property operations relating directly to the Activities.

1.2

It is understood that, notwithstanding article 10.1 hereinafter:

	a)		until COMPANY has been registered and fully licensed in [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] to conduct the Activities in such countries and until completion of the client contracts in progress at the date of such local registration(s)/license(s), the equipment transferred to COMPANY under the APA will be leased to CGG at a leasing hire to be mutually agreed and the clients contracts will continue to be carried out by CGG.

	b)		CGG will be entitled to continue activities in [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] through the relations it currently has with [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT]

			The equipment presently located in [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] and to be sold to COMPANY will be then leased to CGG for its operations in [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] with [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT], at a lease rate to be mutually agreed until such date as decided by CGG.

CGG will be entitled to continue its current activities in the Jebel Ali Free Zone, through its branch, and consisting of importing, exporting, maintaining, repairing and upgrading offshore and onshore vehicles and equipment, procuring spare parts, services and providing technical support to CGG’s and its affiliates’ operations, including those of the COMPANY, when required and under terms and conditions to be mutually agreed.

1.3		In case clients request offers or services or the COMPANY wishes to provide offers or services including both (i) the Activities, as defined in the first paragraph of Article 1.1 a) and (ii) other products or services such as, but not limited to, equipment, offshore streamers seismic data acquisition, permanent or semi-permanent seismic data acquisition, field monitoring and/or instrumentation, processing and/or interpretation (the “Excluded Business”), such Excluded Business will not be part of the COMPANY business. The COMPANY will promptly inform CGG of such business opportunities and CGG will decide whether to pursue those business opportunities in relation with the Excluded Business or not.

		In case CGG decides to pursue such opportunities:

	•		the part of the contract with clients related to the Activities will be fully carried out by the COMPANY; and

	•		the part of the contract with clients related to the Excluded Business will be carried out by CGG or any of its affiliates.

		In such case, CGG and the COMPANY will do their best efforts to have a tripartite agreement with the client under which they will act severally or to have separate agreements with clients for the Activities (the agreement with client being signed by COMPANY) and for the Excluded Business (the agreement with client being signed by CGG). If any of such schemes is not accepted by the client, CGG will decide whether the contract with the client will be signed by the COMPANY or CGG acting as prime contractor. In such case the Excluded Business (if the COMPANY is the prime contractor) will be fully subcontracted to CGG or the Activities (in case CGG is the prime contractor) will be fully subcontracted to the COMPANY on a back-to-back basis, the subcontracting party assuming and benefiting from all rights and obligations under the contract with the client as far as they relate to the Excluded Business or the Activities, as if it was the prime contractor.

		For the avoidance of doubt, in case a request or an offer is only related to an Excluded Business, such opportunity or offer will be conducted by CGG, exclusively in its own name and on its own behalf.

1.4.		It is hereby understood that according to the articles of incorporation of Arabian Geophysical & Survey Company Ltd (“ARGAS”), a Saudi company conducting land seismic acquisition business in the Kingdom of Saudi Arabia and in which TAQA and CGG are the shareholders, TAQA and CGG have agreed that ARGAS and the COMPANY shall co-operate for the Activities in the GCC Countries according to the terms and conditions attached hereto as Appendix I.

		Therefore, as long as such cooperation between ARGAS and the COMPANY will be in force under the terms and conditions attached hereto:

COMPANY shall not promote or conduct any of the Activities (Article 1.1 a) in the Kingdom of Saudi Arabia; and

COMPANY and ARGAS will cooperate for the Activities in the GCC Countries according to the terms and conditions of ARGAS’s articles of association attached hereto as Appendix I.

ARTICLE (2)

		Such purchase price will be paid by TAQA to CGG as soon as possible after Completion and in any and all cases by or on July 8, 2006, by wire transfer to the following CGG’s bank account or any other account notified by CGG :

		BNP PARIBAS Branch : Massy Saclay 2/12, Chemin des Femmes 91300 Massy France

It is understood that such indemnification by CGG to TAQA will be limited to a percentage of the above mentioned liabilities ; such percentage being equal to the percentage held by TAQA in the share capital of the COMPANY at the date such liabilities become final for the COMPANY.

			CGG hereby represents and warrants that, at the date of the present Agreement, there is no pending litigation involving the COMPANY, whether as claimant or defendant.
