If a Substitute Well is proposed under the Operating Agreement and Ridgewood is not a participating Party, this Participation Agreement shall terminate and the terms of the Operating Agreement shall apply and govern the interests of the Parties.

Article IV
Operating Agreement and Area of Mutual Interest

4.1 All operations on the Contract Area shall be governed by the Operating Agreement attached hereto as Exhibit “B”. The Parties to the Operating Agreement may, by agreement amongst them, amend the Operating Agreement from time to time. The Parties agree that all provisions of the Operating Agreement shall apply to all operations conducted after the Effective Date within the Contract Area, except as otherwise provided in this Agreement. Should any conflict or inconsistency exist between the Operating Agreement and this Agreement as to the matters addressed herein, or in the event this Agreement addresses matters not included in the Operating Agreement, this Agreement shall prevail.

4.2 LLOG shall provide Ridgewood with any and all raw well data and information obtained and/or results of analyses performed through the conduct of the drilling of any xxxxx by LLOG on the Contract Area in which Ridgewood is a participant, as further provided for in Exhibit “C”, and any additional data and/or information that Ridgewood may become entitled to pursuant to the terms of the Operating Agreement.

4.3 LLOG and Ridgewood hereby create an Area of Mutual Interest (“AMI”) covering the South-half of the South-half (S/2 S/2) of Green Canyon Block 97. This AMI shall terminate three (3) years after the Effective Date, unless earlier terminated by the terms herein. If a Party acquires an interest or a right to acquire an interest in Green Canyon Block 97 (the “Acquiring Party”), the interests of the Parties shall be seventy five percent (75%) to LLOG if Ridgewood is the Acquiring Party and twenty five percent (25%) to Ridgewood if LLOG is the Acquiring Party. Under any circumstance, within fifteen (15) days after the date on which the Acquiring party acquired the interest (or the right to acquire the interest), it shall notify the non-Acquiring party in writing of such acquisition. The notice shall describe the interest acquired and the actual costs, burdens and/or obligations reserved or to be reserved to acquire such interest. Upon receipt of such notice, the non-Acquiring party shall have thirty (30) days after receipt of the notice to exercise its right to acquire its share of such interest. Upon receipt of the non-Acquiring party’s share of the costs or upon receipt of the non-Acquiring party’s written acceptance of the burdens or obligations which must be incurred to earn the interest, the Acquiring party shall assign the appropriate interest to the non-Acquiring party.

Article V.
Reimbursement of Land Sunk Costs and Assignment of Leases

5.1 Within five (5) business days of Ridgewood’s execution of this Participation Agreement, Ridgewood agrees to pay LLOG $248,075.00, which represents Ridgewood’s proportionate share of the Lease bonuses, rentals and geological and geophysical costs (“Land Sunk Costs”) incurred by LLOG prior to the Effective Date for each Prospect.

Thereafter ownership of the Leases in the Contract Area shall be as follows:


	LLOG	75%
	Ridgewood Energy Corporation	25%

The form of assignments into Ridgewood shall be similar to the form of Assignment attached hereto as Exhibit “D”. Ridgewood shall bear its proportionate 25% share of the Lease royalty and its proportionate 25% share of the overriding royalty burdens on the Leases, such overriding royalty interest burdens being more fully described on Exhibit “E” attached hereto.

5.3 Any assignment(s) of record title interest delivered by the Parties pursuant to this Agreement shall be delivered without warranty of title, whether express or implied, except as to persons lawfully claiming by, through or under the assignor, but not otherwise, and shall be free and clear of all burdens or other encumbrances on the leasehold, except for the assignor’s share of the lessor’s royalty, overriding royalty and those existing burdens as set forth in Exhibit “E” attached hereto. Further, any such assignment(s) delivered by the Parties pursuant to this Agreement shall be subject to the terms of this Agreement, the MC 489 Agreement and the Operating Agreement.

5.4 The assignment(s) of record title interest executed pursuant to this Agreement require approval by the MMS. The assignee under any assignment(s) of record title interest executed pursuant to this Agreement shall promptly (i) file of record any assignment of record title interest in the appropriate governmental records and (ii) file for approval with the MMS (or other applicable governmental agencies) all assignment documents for the assigned interest. Should approval of the MMS (or any other similar governmental agency having jurisdiction) be denied, the Party receiving notice of such denial agrees to provide the other Party with written notice of such occurrence, along with a copy of all associated written communications, and the Parties agree to develop a revised form of assignment in an effort to meet the MMS’ or other appropriate agency’s requirements for approval. In the alternative, each Party shall execute and deliver, or cause to be executed and delivered, such other documents and take such other actions as a Party may reasonably request in an effort to comply with any such approval requirements. Ridgewood shall execute the necessary “Designation of Operator” form (MMS Form 1123) designating LLOG as the operator of the Leases and as designated applicant for oil spill financial responsibility for the Leases, along with any other documents required to allow LLOG to serve as operator of the Leases.

5.5 Either Party’s rights and obligations hereunder may be assigned to a willing and financially able party subject to the terms and conditions of the Operating Agreement. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective heirs, successors, representatives and assigns and shall constitute a covenant running with the lease comprising the Contract Area.

ARTICLE X
MISCELLANEOUS PROVISIONS

10.1 This Agreement together with the instruments referred to herein and the Exhibits attached hereto, embody the entire agreement between the Parties with regard to the subject matter hereof, and supersede all other prior agreements, arrangements, understandings, negotiations and discussions, whether oral or written between the Parties relating to the subject matter hereof and there are no warranties, representations or other agreements between the Parties in connection with the subject matter hereof except as specifically set forth in this Agreement or in subsequent documents delivered pursuant thereto.

10.2 Except for the definition headings contained in Article 1, all of the captions, numbering sequences and paragraph headings used in this Agreement are inserted for convenience only and shall in no way define, limit or describe the scope or intent of this Agreement or any part thereof, nor shall they have any legal effect other than to aid in a reasonable interpretation of this Agreement.

10.3 Each Party has had the benefit of independent representation with respect to the subject matter of this Agreement. This Agreement, though drawn by one Party, shall be considered for all purposes as prepared through the joint efforts of the Parties, and shall not be construed against one Party or the other as a result of the preparation, submittal or other events of negotiation, drafting or execution hereof.

10.4 Each of the Exhibits attached to this Agreement are incorporated into this Agreement by reference as fully as if the text of each Exhibit were set forth within the body of this Agreement.

10.5 In the event of any conflicts or inconsistencies between the provisions of this Agreement and any other agreement, including any agreement referenced herein to be executed by the Parties hereafter, the provisions of this Agreement shall control to the extent of such conflict.

10.6 The Parties agree that prior to making any public announcement or statement with respect to the transactions or operations contemplated by this Agreement, the Party desiring to make such public announcement shall obtain the prior written approval of the other Party to the text of such announcement or statement, which approval shall not be unreasonably withheld; provided, however, that any Party shall have the right, for any reason, to deny approval in the event the announcement or statement specifically names or otherwise identifies said Party.
