    Article
II

    Initial Test
Well

    


    


    2.1           Initial Test
Well.              
 NEWFIELD, as operator under the Operating Agreement (defined in Article
III below), and subject to rig availability and obtaining all requisite permits,
agrees to use reasonable efforts to commence, or cause to be commenced, on or
before [Redacted], actual drilling of the [Redacted] ("ITW") at an approximate
surface coordinate location of[Redacted]. The ITW is to be drilled as an
Exploratory Well (as such term is used in the Operating Agreement) to 22,000’ MD
/ TVD or a depth sufficient to test the stratigraphic equivalent of the ’21,000’
and 22,000’ Sand’ (the “Objective Depth”), whichever is the lesser depth.
 An Authority for Expenditure (“AFE”) for the ITW is attached to this
Agreement as Exhibit “A-1” (the “Approved AFE”) and by the execution hereof,
each of NEWFIELD and RIDGEWOOD agrees to participate in the drilling of the ITW
in accordance with the terms hereof.  Contemporaneously with the
execution of this Agreement, RIDGEWOOD agrees to execute and deliver to NEWFIELD
a counterpart copy of the Approved AFE.

    


    The
failure to timely commence the drilling of the ITW and the Parties agreement to
terminate this Agreement, shall result in the termination of this Agreement, the
return of the Cash Consideration by NEWFIELD to RIDGEWOOD and the reassignment
from RIDGEWOOD to NEWFIELD of all of its record title interest in and to the
Leases.    Otherwise, there shall be no penalty for failure
to timely commence the drilling of the ITW.

    


    


    2.2           Substitute Well.  
In the event the ITW should encounter rock salt, heaving shale, excessive
water flow, excessive pressure, igneous or other impenetrable formation or other
conditions which would render further drilling impracticable or uneconomic and
preclude the ITW from reaching the Objective Depth, then and in such event
NEWFIELD shall have the exclusive option to propose within sixty (60) days
following the abandonment of the ITW drilling of a substitute
well (“Substitute Well”) therefore, provided same is drilled to the
Objective Depth and under the same terms and conditions as the
ITW.   RIDGEWOOD shall have no obligation to participate in the
Substitute Well; provided RIDGEWOOD shall have thirty (30) days, or forty-eight
(48) hours in the event that a rig is on location, from receipt of the AFE for
the Substitute Well to elect whether it shall participate in such Substitute
Well. Failure to respond within the time period allowed shall be deemed to be an
election not to participate in the Substitute Well.  In the
event  NEWFIELD does not propose a Substitute Well within the time
period provided for above, then RIDGEWOOD may propose the drilling of a
Substitute Well pursuant to the terms of the Operating
Agreement.  NEWFIELD or Ridgewood shall have the continuing option to
drill additional Substitute Wells, provided that no more than sixty (60) days
elapse between the date the drilling rig was released from the last operation on
such Substitute Well and the commencement date of drilling operations for the
next Substitute Well drilled therefor.

    2.2.1  
If the ITW fails to reach its Objective Depth, and RIDGEWOOD’s share of costs
and expenses incurred in connection with the ITW has not yet reached the Promote
Cap, then:

    


    (i) if a
Substitute Well is proposed and RIDGEWOOD elects not to
participate therein, then RIDGEWOOD shall pursuant to Article 4.3,
reconvey to NEWFIELD a 15%  record title interest in and to the Leases
and this Agreement shall terminate and neither Party shall have any further
obligations or liabilities hereunder, except with respect to the fulfillment of
payment and indemnity obligations accrued prior to such
termination;

    


    (ii)  if
a Substitute Well is proposed and RIDGEWOOD does elect to
participate therein, this Agreement shall remain in full force and effect
as though the Substitute Well was the ITW; and

    


    (iii) if
a Substitute Well is proposed and RIDGEWOOD elects to
participate therein, but such well is not drilled, RIDGEWOOD shall retain
its undivided fifteen percent (15%) record title interest in and to the Leases
previously conveyed by the Assignment hereunder and any future operations on the
Prospect by the Parties shall be governed by the Operating
Agreement.

    


    2.2.2  
If the ITW fails to reach its Objective Depth and RIDGEWOOD’s share of costs and
expenses incurred in connection with the ITW has reached the Promote Cap,
RIDGEWOOD shall retain its record title interest in and to the Leases received
by the Assignment pursuant to Section 4.2 hereof, and the consequences of
RIDGEWOOD’s election to participate or not to participate in the Substitute Well
shall be governed by the provisions of Article 16 of the Operating Agreement as
described below.

    Subject
to Sections 2.2.1 and 2.2.2, in the event that a Substitute Well is proposed by
RIDGEWOOD and drilled in accordance with this Agreement, the interest of any
non-participating Party in the drilling of such Substitute Well shall be subject
to the terms and conditions of Article 16 of the Operating Agreement as
described below; however, notwithstanding anything to the contrary in this
Agreement, in the event NEWFIELD elects not to participate in the drilling of a
Substitute Well, and RIDGEWOOD bears all or a portion of such Party’s interest
in the Substitute Well, the acquired interest shall not be subject to the
acreage forfeiture provisions of the Operating Agreement, but instead will be
subject to the non-consent penalty percentages applicable to Exploratory
Operations as defined in the Operating Agreement Article
16.5.1.  Regardless of whether RIDGEWOOD elects to participate or not
to participate in a Substitute Well, NEWFIELD shall retain the Cash
Consideration, as such term is hereafter defined.

    


    


    2.3           ITW Drilling
Costs.  RIDGEWOOD shall bear and pay thirty percent (30.0%) of
the actual costs to drill and test the ITW to Casing Point ; however, if prior
to reaching Casing Point the actual aggregate cost of the ITW, and any
Substitute Well therefor, exceeds one hundred percent (100%) of the dry hole
cost estimate provided for in the Approved AFE (“ Promote Cap”), RIDGEWOOD shall
bear and pay fifteen percent (15%) of the actual costs to drill and test the ITW
thereafter.  Casing Point shall be defined as that point in time when
the ITW (or Substitute Well therefor) has reached its Objective Depth and all
open hole logs and tests have been conducted in accordance with the Approved
AFE.  If RIDGEWOOD elects to participate in a Substitute Well, any
cost to drill the ITW will be carried over to the Substitute Well to calculate
the Promote Cap for purposes of determining when RIDGEWOOD's cost-bearing
interest reduces to fifteen percent (15%).  Subject to the terms and
conditions of this Agreement, all operations in the ITW subsequent to Casing
Point, shall be conducted in accordance with the terms and provisions of the
Operating Agreement and, subject to participation elections, shall be shared 15%
by RIDGEWOOD and 85% by NEWFIELD et al, its co-owner, and their successors and
assigns.

    


    Article
III

    Operating
Agreement

    


    3.1           Operating Agreement. The Leases will be
subject to that certain Offshore Operating Agreement by and between NEWFIELD, as
Operator, and the Non-Operators designated therein, dated effective July 1, 2008
(the “Operating Agreement”), which is attached hereto as Exhibit “B”, and which
will govern operations upon the Leases (subject to RIDGEWOOD’s right to earn an
interest in the Leases per this Agreement).   At the time
RIDGEWOOD executes this Agreement, RIDGEWOOD shall also execute and deliver the
Operating Agreement, at which time it shall be deemed to be a party
thereto.  If there is a conflict between the terms and conditions of
this Agreement and the terms and conditions of the Operating Agreement prior to
the earlier of: (a) reaching the Objective Depth in the ITW or (b) RIDGEWOOD’s
costs and expenses incurred in the ITW and any Substitute Well therefor reaching
the Promote Cap, then the terms and conditions of this Agreement shall
control.  Thereafter, the Operating Agreement shall control.
Notwithstanding the foregoing, the provisions of Article 27 of the Operating
Agreement (Area of Mutual Interest) will be applicable to the Parties hereto
from and after the Effective Date and should RIDGEWOOD be required to reassign
its interest in accordance with Article 4.3 of this Agreement then the
Reassignment will also include any and all rights or interest acquired by
RIDGEWOOD, as applicable, pursuant to said Article 27.

    6.3           Relationship of the
Parties.  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.  Solely for purposes of federal income taxation and purposes of
certain state income tax laws which incorporate or follow federal income tax
principals as to tax partnerships, however, Each of the Parties hereto agrees
not to elect, under the authority of Section 761(a) of the Internal Revenue Code
of 1986, to be excluded from all the provisions of Subchapter K of Chapter I of
Subtitle A of said Internal Revenue Code of 1986.  With regard to the
resulting tax partnership, the Parties hereby incorporate by this reference, as
if set forth herein in full, the tax partnership provisions set forth on Exhibit
“J” to the Operating Agreement, with the tax partners in such tax partnership
being NEWFIELD, RIDGEWOOD and the other parties to the
Operating Agreement with the Tax Reporting Partner being NEWFIELD. 
This Agreement and operations hereunder relate solely to the Prospect, and no
Party hereto shall have any obligation of any kind to any other Party hereto as
to any other lease, land or minerals (whether in the vicinity of the Lease or
not) by virtue of this Agreement or such operations or otherwise except as may
be provided in the Operating Agreement, Article III hereof or evidenced by
written agreement of such Parties.

    6.4           Rentals.  To the
best of NEWFIELD's knowledge, as of the effective date of the assignment, all
rentals and any other payments due pursuant to the terms of the Leases subject
to this Agreement have been properly and timely paid and said Leases are now in
full force and effect as of the Effective Date.  As of the Effective Date
of this Agreement, RIDGEWOOD will be responsible for its prorata share of the
rentals on the Leases.

shall control to the extent of such conflict.

subject to the arbitration provisions of the Operating Agreement.

    


    6.9           Severability.  If any

for required disclosures, including but not limited to disclosures to
governmental agencies and/or stock exchanges, or as otherwise provided for in
