However, if the JDA withdraws all awards in respect of Block 3
and places Block 3 in a subsequent bid round, then the Parties shall use reasonable endeavors to execute a mutually acceptable bidding agreement (using the AIPN Bidding Agreement Form as a model) and submit a joint bid for Block 3.

without any further obligations to the other Party.

United States Tax Election.

If, for United States federal income tax purposes, this Agreement and the operations under this Agreement are regarded as a partnership, each Party elects to be excluded from the application of all of the provisions of Subchapter "K", Chapter 1, Subtitle "A" of the United States Internal Revenue Code of 1986, as amended (the "Code"),
to the extent permitted and authorized by Section 761(a) of the Code and the regulations promulgated under the Code. Operator, if it is a U.S. Party, is authorized and directed to execute and file for each Party such evidence of this election as may be required by the Internal Revenue Service, including all of the returns, statements, and data required by United States Treasury Regulations Sections 1.761-2 and 1.6031(a)-1(b)(5) and shall provide a copy thereof to each U.S. Party. However, if Operator is not a
U.S. Party, the Party who holds the greatest Participating Interest among the U.S. Parties shall fulfill the obligations of Operator under this Section. Should there be any requirement that any Party give further evidence of this election, each Party shall execute such documents and furnish such other evidence as may be required by the Internal Revenue Service or as may be necessary to evidence this election.

No Party shall give any notice or take any other action inconsistent with the foregoing election. If any income tax laws of any state or other political subdivision of the United States or any future income tax laws of the United States or any such political subdivision contain provisions similar to those in Subchapter "K", Chapter 1,
Subtitle "A" of the Code, under which an election similar to that provided by Section 761(a) of the Code is permitted Operator (or each U.S. Party if required for such purpose) shall make such election as may be permitted or required by such laws and each Non-U.S. Party shall join therein to the least extent necessary to permit such election to be effectively made. In making the foregoing election or elections, each U.S. Party states that the income derived by it from operations under this Agreement can be adequately
determined without the computation of partnership taxable income.

Unless approved by every non-U.S. Party, no activity shall be conducted under this Agreement that would cause any non-U.S. Party to be deemed to be engaged in a trade or business within the United States under United States income tax laws and regulations or to be subject to any U.S. tax reporting or payment obligations that it would
not otherwise be subject to.

	
7.

Agreement, and telephone numbers for the Parties are listed below as a matter of convenience only.

"Received" for purposes of this Article shall

Execution Version

Addax accepts the terms and conditions set by the JDA for the awards of Block 4 and specifically acknowledges and agrees to pay the signature bonus and fulfill the minimum work program attributable to the Assigned Interest and the Retained Interest.

Addax may not withdraw from the PSC after the Assignment prior to the completion of the Work Program for Phase I of the Exploration Period of the PSC (“Phase I”). However, after the completion of the Work Program for Phase I, nothing contained in this Section 3 shall prevent Addax from relinquishing its
Participating Interest and withdrawing from the PSC in its sole discretion in accordance with the terms of the PSC and the JOA. The Parties agree to support the position in the JOA that if Addax elects to relinquish its Participating Interest and withdraw entirely from the PSC and the JOA after the completion of the Work Program for Phase I, any preemption rights, preferential purchase rights, or similar provisions shall not apply to Addax's interest and Addax will convey back to ERHC, free of all costs and encumbrances,
the Assigned Interest and all Addax obligations provided in this Agreement shall terminate (except for obligations incurred prior to the withdrawal) and neither Party shall have any further obligations to the other Party.

Undertakings of the Parties

Addax shall pay to ERHC by wire transfer of readily available funds, (i) no later than ten (10) days after the execution of this Agreement, the sum of One Million Three Hundred and Fifty Thousand US dollars (US$ 1,350,000), and (ii) no later than ten (10) days after the execution of the PSC in respect of Block 4 or
the acquisition of the Assigned Interest by Addax, whichever is later, the sum of Sixteen Million Six Hundred and Fifty Thousand US dollars (US$16,650,000).

	 	
(b)
	
ERHC and Addax shall both participate in the negotiation of the PSC and Addax, in consultation with ERHC, shall act as the lead negotiator for the Parties during such negotiation. Addax shall appoint negotiators mutually acceptable to ERHC who shall be authorized to participate in the PSC negotiations with ERHC and on behalf of Addax. Both Parties shall be advised of upcoming meetings
with the JDA and consult regarding strategy, contract terms and conditions, and the progress of negotiations. Each of such Parties shall be entitled to be present at and participate in all negotiations with the JDA, if possible.

	 	
(c)
	
Neither Party shall have the right to bind the other Party without such Party's prior written approval.

	 	
(d)
	
Notwithstanding anything to the contrary contained herein, each Party shall bear its own costs related to the negotiation and execution of this Agreement, the PSC and the JOA.

Except as provided in the next sentence, if Addax terminates this Agreement for any reason prior to the Transfer Date, and subsequently acquires an interest in Block 4, it shall immediately notify ERHC, and upon request, execute such documentation as is necessary to vest ERHC with an interest consistent with the terms
and conditions of this Agreement. However, if the JDA withdraws all awards in respect of Block 4 and places Block 4 in a subsequent bid round, then the Parties shall use reasonable endeavors to execute a mutually acceptable bidding agreement (using the AIPN Bidding Agreement Form as a model) and submit a joint bid for Block 4. If the bid is successful, this Agreement shall then apply to bid interest acquired by the Parties. If the bid is not successful and neither ERHC or Addax is awarded an interest in Block
4, then either Party may acquire an interest in Block 4 from one or more of the successful bidders without any further obligations to the other Party.

any such invalid provision shall be deemed severed from this Agreement without affecting the validity of the balance of this Agreement.

	 	
(f)
	
Modifications.

There shall be no modification of this Agreement except by written consent of all Parties.
