or before December 31, 2008 (the “Obligation Date”), MEI as operator under the
Operating Agreement, shall (i) commence or cause to be commenced the drilling
of the IEW at a location that is [REDACTED] and (ii) subject to Article 3.2,
drill the IEW to the Objective Depth in accordance with the AFE and Well Plan.
Ridgewood and Stone, having reviewed the Well Plan and AFE with all particulars
(i.e. casing program, mud system, logging/evaluation program, and TD criteria),
hereby acknowledge their agreement with the IEW well design, including but not
limited to, well location (surface and bottom-hole) and the projected
penetration point into the objective interval and do hereby approve such Well
Plan and AFE for the IEW. In the event operations aren’t commenced on or before
the Obligation Date, then Ridgewood and/or Stone may terminate its respective
participation in the IEW and this Agreement by notifying MEI and LLOG in
writing within ten (days) of the termination of the Obligation Date. In the
event Ridgewood or Stone elect to terminate its participation, such party will
re-assign its interest previously assigned and MEI and LLOG will promptly
reimburse the assigning party for all sums previously paid by such party

After the Promote End Date, and subject to election
rights under the Operating Agreement, Ridgewood’s cost bearing percentage (and
ownership percentage) shall be 25.00% of all subsequent costs incurred in the

After the Promote End Date, and subject to election rights under the Operating
Agreement, Stone’s cost bearing percentage (and ownership percentage) shall be
10.00% of all subsequent costs incurred in the IEW or any Substitute Well, and

impracticable and preclude drilling the IEW (or any Substitute Well) to the
Objective Depth, then and in such event any party to the Operating Agreement
described in Article IV below may propose within ninety (90) days
following rig release for such well the drilling of a substitute well

provided all costs with respect to the IEW and any Substitute Well will be
added together to calculate the Cumulative Cost Point for purposes of
determining when Ridgewood’s and Stone’s cost-bearing interests reduce as
provided in Article 3.1. If the Promote End Date has not occurred, and a.) the
IEW has not reached Objective Depth and b.) a Substitute Well is proposed,
approved, timely commenced under the Operating Agreement and Ridgewood and/or
Stone are not a participating party(ies), this Participation Agreement shall
terminate as to such non-participating party(ies), subject however to the provisions
of Article VIII, and such non-participating party(ies) shall reassign to MEI
and LLOG any interests previously assigned to such non-participating party(ies)
pursuant to Article 5.2. Notwithstanding the above, if the Promote End Date has
not occurred, and a.) the IEW has not reached Objective Depth and b.) a
Substitute Well is proposed, approved, timely commenced under the Operating
Agreement and Ridgewood and/or Stone are not a participating party(ies), such
non-participating party(ies) shall have the option to tender to Mariner and
LLOG a cash payment equal to such party’s proportionate share (for Ridgewood
33.3333% and for Stone 13.3333%) of the difference between cumulative costs
incurred in the IEW and $41,010,503.00, and such payment shall entitle such
non-participating party to retain operating rights from the surface to 100’

below the stratigraphic equivalent of the deepest producible interval
encountered in the IEW in which it was a participating party. The provisions of
this Article 3.2 shall apply to each successive Substitute Well, if any.

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 and Stone shall each execute the necessary “Designation of Operator”
form (MMS Form 1123) designating MEI as the operator of the Lease and as
designated applicant for oil spill financial responsibility for the Lease,
along with any other documents required to allow MEI to serve as operator of
the Lease. MEI, Ridgewood and Stone shall each execute the necessary
“Designation of Operator” form (MMS Form 1123) designating LLOG as the operator
of the [REDACTED] Lease and as the designated applicant for oil spill financial
responsibility for the [REDACTED] Lease, along with any other documents
required to allow LLOG to serve as operator of the [REDACTED] Lease.

          5.5      Any
Party’s rights and obligations hereunder may be assigned to a willing and
financially and otherwise able party subject to the terms and conditions hereof
and 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 permitted assigns and shall constitute a covenant running with each of the
leases comprising the Contract Area.

          5.6      Should
any Party, individually or jointly with others (the “Acquiring Party”), acquire
an interest in the [REDACTED] (the “AMI”), then the Acquiring Party shall,
within thirty (30) days following the execution of a definitive agreement, give
written notice thereof to the other Parties, which notice shall include a full
description of the particulars of the acquisition, including the nature, amount
and proportion of the interest involved, and the cost, terms and conditions
upon which it was acquired or is proposed to be acquired. The other Parties
shall then have the right and option, but not the obligation, for a period of
thirty (30) days from the receipt of such notice, to elect to acquire its
prorata share (based on ownership in the Lease) of such acquired interest by
giving written notice to the Acquiring Party of its election to participate in
the acquisition. Such prorata share shall be equal to each Party’s Lease
interest set forth in paragraph 5.2. above, multiplied by the interest acquired
by the Acquiring Party. During the 30-day notice period, the Acquiring Party
shall, upon request, furnish copies to the other Parties or make available for
inspection, at the other Parties’ expense, all leases, assignments, contracts,
and other documents pertaining to the acquired interest(s) involved that are in
the Acquiring Party’s possession or subject to its control. Promptly upon
receipt of the written notice from a Party indicating its election to
participate, the Acquiring Party shall execute and deliver an assignment
conveying to that Party, without express or implied warranty of title, the
appropriate undivided share of the Acquiring Party’s right, title and interest
in and to the acquired interest involved, subject to that Party paying or
reimbursing the Acquiring Party for such Party’s share of actual consideration
paid or agreed to be paid for such acquisition and agreeing to promptly
discharge such Party’s share of all obligations incurred as consideration for
such acquisition. A Party’s failure to make such election within the aforesaid
30-day period shall conclusively constitute a waiver by the Party of its right
to receive a share of the acquired interest.

          Any
acquired interest which becomes owned by all Parties pursuant to this AMI shall
be committed to the operating agreement to which the acquired interest is
subject to, or if none, then an operating agreement in the form of the
[REDACTED] Operating Agreement, naming MEI as Operator provided MEI is then the
Operator of the [REDACTED] and owns an interest in the [REDACTED]. This AMI and
the rights and obligations for each Party set forth herein shall expire on the
earlier of: a) one year from rig release from the IEW (or Substitute Well
therefor) if the IEW is completed as a dry hole or December 31, 2010, and,
notwithstanding any other provisions in this Agreement to the contrary, this
Article 5.6 shall not terminate until December 31, 2010 and shall survive any
prior termination of this Agreement.

ARTICLE VIII

TERM

          8.1      Other
than Article 5.6, which shall expire on December 31, 2010 as more fully set
forth therein, the term of this Agreement shall terminate upon the earlier of:
(i) ninety (90) days after the date or rig release from the IEW or, if there is
any Substitute Well(s), then ninety (90) days after the date of rig release
from the last Substitute Well (subject, however, to the provisions of Article
3.2 of this Agreement which may result in the earlier termination of this
Agreement in the event of a Substitute Well(s)), or (ii) by the mutual
agreement of the Parties, or (iii) the occurrence of the events set forth in
the last sentence of Article 3.2, whichever event occurs first. Upon
termination of this Agreement, any and all future operations to be conducted on
the Lease or on the [REDACTED] Lease for the joint benefit of the Parties shall
be conducted under the Operating Agreement. Termination of this Agreement shall
not relieve any Party from any obligations hereunder accruing or accrued prior
to the date of termination, nor deprive any Party of any right or remedy
otherwise available to such Party. Furthermore, upon termination of this
Agreement, the provisions of Articles 6.1 and 7.1 and the provisions of Article
X shall survive such termination.

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, including
without limitation, the Offer Letter, 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. Notwithstanding the foregoing, this
Agreement shall not supersede any existing agreement between MEI and LLOG. This
Agreement may be supplemented, altered, amended, modified or revoked only in
writing, signed by all Parties hereto.

          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,
unless the Parties otherwise expressly so provide.

          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 or delayed. Nothing contained in this Article 10.6 shall
be construed to require any Party to obtain approval to disclose information to
any State or Federal governmental authority or agency, to the extent required
by applicable law or by any applicable rules, regulations or orders of any
governmental authority or agency having jurisdiction, or as necessary to comply
with any disclosure requirements of applicable securities laws or any
applicable stock exchanges, or if otherwise permitted under the terms of the
Operating Agreement.

          10.7    This Agreement may be
executed by signing the
original or a counterpart hereof. If this Agreement is executed in multiple
counterparts, each counterpart shall be deemed an original and all of which
when taken together shall constitute but one and the same Agreement with the same
effect as if all Parties had signed the same instrument. This Agreement may
also be ratified by separate instrument referring to this Agreement and
adopting by reference all the provisions of this Agreement. A ratification
shall have the same effect as an execution of the original Agreement.

          10.8    Disputes
arising under this Agreement shall be resolved in accordance with the dispute
resolution provisions of the Operating Agreement.

          10.9    If any provision of this
Agreement is for any
reason held to violate any applicable law, governmental rule or regulation, or
if the provision is held to be unenforceable or unconscionable, then such
provision shall be deemed null and void; but the invalidity of that specific
provision shall not be held to invalidate the remaining provisions of this
Agreement. All other provisions in the entirety of this Agreement (including
all Exhibits) shall remain in full force and effect unless the removal of the
invalid provision destroys the legitimate purposes of this Agreement, in which
event this Agreement shall be canceled and terminated. In the event any
provision of this Agreement is or shall become unenforceable because of changes
in applicable laws, or interpretations thereof, or should this Agreement fail
to include a provision that is required as a matter of law, the validity of the
other provisions of this Agreement shall not be affected. If those
circumstances should arise, the Parties shall negotiate in good faith the
required modifications to this Agreement to place themselves in the same
position (insofar as possible), as they would have been in but for the change
in applicable laws or interpretations thereof. If they cannot agree, the matter
shall be resolved in accordance with the dispute resolution provisions of the
Operating Agreement.

          10.10  This
Agreement does not benefit or create any rights in any person or entity not a
party to this Agreement. Further, each Party represents that upon execution of
this Agreement it has secured all necessary management approvals or other
corporate approvals necessary to make this Agreement a fully binding contract.

          10.11  It is not the purpose or intention
of this Agreement to create, and this Agreement will never be construed as
creating, a joint venture, mining partnership or other relationship whereby any
Party will be held liable for the acts, either of omission or commission, of
any other Party, and the liabilities of each of the Parties hereto shall be
several and not joint or collective. However, solely for federal tax purposes,
if the Parties intend and agree for this Agreement to constitute a partnership,
then the Parties will make a separate written election, under the authority of
Section 761(a) of the Internal Revenue Code of 1986, not to be excluded from
the provisions of Subchapter K of Chapter I of Subtitle A of said Internal
Revenue Code of 1986. 

          10.12  No
waiver by either Party of any default by the other Party in the performance of
any provision, condition or requirement herein shall be deemed to be a waiver
of, or in any manner a release of the other Party from, performance of any
other provision, condition or requirement herein, nor deemed to be a waiver of,
or in any manner a release of the other Party from, future performance of the
same provision, condition or requirement; nor shall any delay or omission of
either Party to exercise any right hereunder in any manner impair the exercise
of any such right or any like right accruing to it thereafter.
